The only thing we have to fear is each other

 As the season of darkness settles on us in the northern hemisphere, bike commuters have to decide whether to continue or suspend their activities until the sun returns again. The biggest danger in night riding is the same as the biggest danger in daylight: motor vehicles.

Cycling is scary enough in full daylight. We hear all the time about riders injured or killed, often by drivers who evade prosecution by leaving the scene. Even if the offender is tracked down, the penalties for ending a cyclist or pedestrian's life are usually laughably mild. If you want to be reminded over and over again how cheap life is, just try to get around without an armored vehicle.

Just recently, a rider here in New Hampshire was killed by a hit-and-run driver. She was a retired police officer training for a benefit ride. As luck would have it, there was enough information from the scene for police to track down the driver and start putting together a case against him. The assault occurred around 10:30 in the morning. That should be prime time for drivers to be awake, aware, and observant. Last I saw, the maximum time he could serve in prison for killing someone in this way was seven years for negligent homicide. And who ever gets the maximum sentence? Maybe a cop killer will, but it still seems like way too little. And if she'd lived, paralyzed and incapacitated, the penalty would be less, because "thank God no one was killed."

Crashes occur. For the most part, operator error is to blame. Even if the cause is defective equipment, it's probably because someone wasn't maintaining the vehicle properly. Look at you own life and think about how many risks you have gotten away with over the years. I most definitely include myself. You get going, driven by a real or imagined sense of urgency, and your visual field narrows as your speed increases. We are remarkably good at making quick ballistic calculations on the fly, but when it fails it can fail spectacularly, as the accumulated risks all converge at once. The unintended consequence could be as mild as a bent fender or as grotesque as a pile of crushed and shattered vehicles, with brains and entrails splashed across the highway. Oopsie.

A bicyclist has no shell of metal, plastic, and glass to take the impact. Any contact tends to be a serious one for the cyclist, simply because of the size and mass of the vehicles involved. Even when cyclists hit each other, the ground is the next stop. There have been fatal crashes where only cyclists and their surrounding environment were involved. Cyclists have struck and killed pedestrians. On popular paths, conflicts are common, because the bicyclists and pedestrians directed there are not a placid herd of grateful plodders. They exhibit the full range of personalities, including the aggressive and the oblivious.

When I lived in a more urban environment, 1979 to 1987, I commuted by bike exclusively, because I did not have a car. The season of darkness is not as long and deep in Annapolis, Maryland, as it is in central New Hampshire, but I did have to ride in the dark a lot. I equipped the bike with the best lights I could get at the time, and I had no problems. But the built environment has a lot more ambient light at night. My commuting route changed as my residence and workplace shifted to different cross-sections of the general area, so sometimes I had short stretches of unlighted road, but they were also not busy at the time. Now all the roads are busy down there, and what were dark and empty stretches are obliterated by lighted sprawl.

Up here, my route is much longer and follows roads that are almost entirely unlighted. The longest part is on a two-lane rural highway with a narrow shoulder. Where it enters Wolfeboro it is narrower, with more bends, and no shoulder. I'm fortunate to live north of town. The route in and out of Wolfe City from the south is much nastier.

Coming out of town, when I will be in the dark in the fall and winter, I could use the Cotton Valley Trail for part of it, and I did, for several years. Before that was an option, and recently, since the pandemic made the trail crowded, I have ridden an indirect but safer route out of town, that bypasses the bendy bit of Center Street. Inbound on Center Street, drivers are compressing and slowing, which makes them more attentive to obstructions like a bike rider. Headed out of town, they're decompressing, speeding up, and have far less patience with some sweaty idiot interrupting their flow. Yes, they need some character education, but since it's unlikely to work, I choose not to do it with my flesh. I evade. However, I have to rejoin the route out where Route 28 assumes its highway configuration, with longer sight lines and a bit of shoulder. The only way I can completely evade the motoring public is to quit riding.

Park and ride options are contrived, because the only places to hang a car are off my direct route. Competition for parking increased when the pandemic sparked the boom in outdoor activities like biking and walking. And as winter deepens the parking places are not plowed out.  That may change as winter activities on the trail system developing around the Cotton Valley Trail expand, but then competition for parking increases even more. And an unattended vehicle may invite theft.

If the only challenges were weather and darkness, I would not hesitate to ride the whole route through much of the winter. Snow and ice make wheels impractical, but most winters are not completely snow covered from end to end, especially in recent years. I have studded tires for one of the bikes rigged for commuting. Without motorists, would there be any incentive to keep the roads clear? Maybe if bike transportation was the norm, or at least much more common, some sort of taxation method would fund road maintenance. Extra points if it didn't involve tons of corrosive substances to melt the ice. Cyclists already pay taxes, but if we were more major beneficiaries of the road network it would be reasonable to make sure that we paid an amount that addressed our actual strain on resources. And just rolling the snow to a firm, frozen surface would give non-fat studded tires a good enough grip. If it's softer than that I'd ski to work.

I've noted before that drivers seem to become more aggressive when cloaked by darkness. It didn't seem that way in Maryland, but it certainly seems that way here. The highway stretch is actually not as scary as Elm Street, which has some tight turns and undulating hills. Traversing the glacial plains, the topography isn't rugged, but it's not flat, either. The road makes a convenient connection to Route 16, so it funnels traffic from as far away as Maine. It's not bumper to bumper busy except on holiday weekends, when it seems to have become a popular bypass for drivers trying to get around backups on Route 16 southbound. Then they all jam up trying to get back out of Elm Street into the crawling southbound flow. At the hours that I use it, I only have the normal local traffic to deal with. But the sparse traffic contributes to the problem of motorist impatience.

In the darkness, motorists are blinding each other with their headlights as they charge toward each other in the narrow space. If it's only a couple of vehicles in each direction, they will endure a moment of tension as they try to negotiate the gap in the radiance of their dueling floodlights. Add a bike rider, and it's just too much to ask of poor drivers who have to put up with so much frustration in their lives.

Day or night, my riding style is heavily influenced by the competition for space on the road. I have never ridden in a place where motorists would peacefully accept a cyclist claiming lane space at a comfortable, relaxed pace. Years of riding will make you smoother, more efficient, and generally faster, but age takes its toll. In nature, you'd be the gazelle that gets dropped by the herd and provides dinner for the lions. Until that time, you develop your own style to keep friction at a manageable level. Riders who are scrappy and enjoy friction will ride in a way that they know will antagonize the motoring public. Or they might ride without regard to laws and conventions because they consider it a right of sorts, and accept the friction as part of the cost. I prefer to try to facilitate everyone's flow as much as I can without subordinating myself -- or cyclists in general -- to the motoring majority. There's a certain bending of the law that helps everyone to keep moving. It's not a zero-sum game. It's a negotiation.

Not everyone deals reasonably. The motorists hold the upper hand in a contest of force. A cyclist has no defense against someone unreasonable. Every driver around you has a personal set of rules that they're applying to you. It seems to me that one limit that some of them set is sunset. When I was much younger and faster, I would routinely ride the commute into October, with only marginal lights. I detected few hassles beyond the normal ones that come with riding on the roads. I carried less back then, and rode a lighter bike. But even then I shut the game down before mid October. I would push it until I could no longer pretend that I'd made it home before dark. Now, with really functional lights, but an older engine and a heavier bike, I would ride happily in the darkness, but it puts me into forbidden territory with these few but regular fellow road users on my route who have decided that I don't belong there after sundown. No alternate route avoids the worst part without a long detour. Is the living free worth the increased risk of dying? Any road cyclist who tells you that they don't think about the possibility of getting maimed or killed every time they go out is either lying or has no imagination at all.

The convenience of Daylight Relocating Time

Daylight Relocating Time arrives this coming Sunday in the states that observe it. Let the whinging begin!

I get that it's disruptive. It may get worse as we age. But throughout my childhood I looked forward to the later daylight. As an adult racing cyclist, I found it very useful as well, for training rides after work. Even without training in the mix, it extends the safe(r) period of riding on the road by putting daylight where a lot of us have to use it, in that span between quittin' time and supper time.

If anyone with the power to set policy is listening, if you decide to stop playing with the clocks, please leave them in the DST position, for this late daylight. I have had to ride in the predawn darkness at times, but riding toward and into the coming day is still better than having to deal with early sunset. Or we could adopt Universal Time overlaid with local time, so that things that need to be scheduled will all be on the same clock (see you at "14:00" for that morning meeting!), but each locality has the option of responding to its own photoperiod and sun angle in a more natural way. Sounds like a mess, but at least it would be a novel mess. And whatever number we set on our alarm clocks, we wouldn't have to shove it one way and then the other twice a year.

I think about this today, because it's totally beautiful outside, and I was considering a bike ride. The weather looks conducive for the coming week, and the long range forecasts indicate that the pattern may have shifted for good. Even more importantly, a man at the conservation commission meeting last night, whose family has been here for generations, wished us all a "good mud season" as we adjourned, meaning that, in his experienced observation, this winter has run its course. That means that any saddle toughening I go through now will probably be good for the rest of the season, unlike years when I make false start after false start and go through that "kicked in the ass" feeling multiple times.

The hitch today was that I was up late last night after the meeting, so I got a slow start this morning. And the best of the day came after the sun got up far enough to put out real warmth. There's no point in going out when it's still in the 30s when the middle of the day will be so much nicer. But it's also my last day off before the work week resumes, so I have a list of things that need to get done, plus some residual paperwork from last night's meeting. I calculated the time needed to gear up, get out, and put everything away again, and substituted some ski-trudging as the quicker and easier activity to launch.

On the subject of freezing and thawing, I might actually plan to ride when the temperature is below freezing, if my route includes dirt roads. We're entering the notorious mud season. Even though the scant snow cover means that the mud season will be short and mild, dirt roads will still be better for riding when an overnight freeze paves them for a few hours.

Daylight Relocating Time would have allowed me to knock off a bloc of time-sensitive chores and still have enough light for a worthwhile ride before sunset. We're not quiiiiiiiiite there yet. It's close, but DRT would make it a very comfortable margin.

The frost heaved roads don't present much of a problem to me actually piloting my bike, but they do make drivers even more erratic as they bob and weave through the hummocks and holes. That occupies more of their attention than the unexpected sight of some bike rider's lights in the dusk. All through the winter I have seen pedestrians in the dusk and darkness, while I was driving, presenting what they think are adequate lights. In every case the display has been more confusing than anything else, even if it was bright. None of them were bright enough to stand out against the glare of oncoming vehicle headlights blasting me at the same time I was trying to keep track of the flickering fireflies of foot traffic.

I know my bike lights are bright enough to gain me a measure of respect on the road, but they're still a lot smaller than car and truck lights, especially some of these new trucks that have four low beams blazing at all times. Whoever is responsible for designing those should be strapped in a chair with his head in a clamp and his eyelids held open with alligator clips, and be forced to stare into that sociopathic wall of light until his eyeballs turn into raisins. Right next to him should be whoever is responsible for the shitty light dispersal pattern of LED headlights in general, staring into a bank of those. They just made a bad situation worse.

Dinky little lights

The early onset of snow and ice forced me into the car more than a month sooner than in past years. This has given me a lot of time to look at fellow road users through the windshield, the way the vast majority of road users view those of us who aren't in a motor vehicle.

I've seen the whole range, from people with no lights to people with conspicuous outfits combining illuminated and reflective elements. The more brightly lighted are certainly more noticeable, but even the most conspicuous is hard to see.

I've discussed the drawbacks of aggressively conspicuous lighting before. That's a different problem. What I noticed most recently is the way night lighting and reflectivity for non-motorized users fails to define them even if it makes them quite noticeable.

Starting at the dark end of the spectrum, pedestrians and cyclists start right out with different minimum recommended lighting. Way back when I was a kid, my father said we should carry a flashlight when walking the dog at night, so that drivers could see us when cars came by. Flashlights are a lot better now, and pedestrians are a lot rarer. I appreciate it when I'm in my car or on the bike and people on foot have a light. But from the car it still doesn't provide instant and definite positioning. The same goes for cyclists with the minimum required lighting, or even a notch better. Any oncoming motor vehicle blasts out the smaller lights of the non-motorized travelers and narrows the space in which to pass safely. More than once I have pulled over and stopped completely rather than go forward into the visual field of blaze and blackness. Any normal driver will just bull through and hope for the best.

More powerful lighting definitely improves the situation for a bicyclist at night. The most powerful head and tail lights define you as a vehicle better than in daylight. But the sheer size of the headlight is never as large and definitive as the lights on a car or truck. If you're on a road where it's inadvisable to take the full lane, you're off to the side a bit, ambiguously lighted and generally moving more slowly than the large, motorized sensory deprivation tanks in which most teens and adults spend most of their lives in developed countries.

The lights on motor vehicles are designed not only to allow drivers to see where they are going in the absence of other light. They also define the shape and size of the vehicle. They are a symbolic language and an aid to navigation. At a glance, a driver can identify the other vehicles by their lights, determine their direction of travel and approximate their speed. Non-standard lighting causes immediate confusion. You will notice this at accident scenes where emergency vehicles are in unusual positions and emergency responders with reflective vests and lights are moving around a scene, particularly early in the response, when drivers are still flowing through the area. You'll see it at construction zones. You'll see it when a motor vehicle is escorting people on foot who might for some reason be using the public right of way for something like a long-distance charity relay or similar event. I have been unable to dig up a link to a story about it, but I recall years ago -- pre-internet -- that a mixed group of fraternity and sorority students were doing a charity run, escorted by a truck with floodlights on the back of it. They were in the right lane of a four-lane, divided highway when a driver ploughed into the runners, killing several. The white floods on the back of the escort truck made it visible, but not identifiable.

At highway speeds -- and even at the lower speeds -- drivers need automatic cues that trigger automatic responses, because they are so conditioned to business as usual. Are they wrong? Of course they're wrong. Drivers should be on the alert at all times for unusual circumstances that require them actually to pilot their craft. Wrong they may be, but they are also normal. The vast majority of the time, they only encounter each other, normally lighted and operating within a fairly narrow range of deviations. Even the speed changes and weaving of a texting idiot fall closer to the norm than the dinky little lights of a bike or pedestrian, or the bright but unfamiliar look of a motor vehicle engaged in non-standard activity.

Take your super-equipped rider with fully reflective garments and lots of lights. You will trigger reports of space aliens, but you still don't give drivers a quickly assimilated spatial reference that they can use to set up a seamless pass. You're just weird looking. I don't say that you shouldn't do it. Just don't be surprised when it fails to provide anything close to perfect safety and confidence. On the approach, even that display can be obliterated by the lights of oncoming traffic. And it didn't really claim your space in the first place. The illuminated human outline of a full reflective suit does reinforce that you are at least humanoid. But that very spectacle might lead to target fixation, as the driver gravitates toward you, gaping in fascination at this apparition floating through the darkness. You're little better off than the rider with just a really decent head and tail light, reflector leg bands and an odd couple of blinkies.

Are there statistics on this? Probably not. Someone would have to care, and get the funding for the study, tabulate and publish the results. I base my conclusions on my own observations as a prisoner in my car, going off to grub for my pittance each day.

Out of the car, we riders and walkers have adapted to the night. It's easy to forget how invisible you are under even the best of circumstances. That's why I don't feel like a pampered pet of the machine age, wallowing in my privilege as I loll in the recliner and pilot my chariot. I feel like I'm making a sacrifice for the team, performing anthropological and sociological research by spending time as a motorist, and studying its effects both physical and psychological. I would prefer to spend more of the time as a brave outrider, facing the elements and making the world a better place one pedal stroke at a time. But the world isn't there yet. Someone has to guide the transition.

Autonomous elements in a semi-autonomous vehicle would improve the passing situation independent of lighting at night. If motor vehicles had sensor systems that could identify the size, speed, and direction of any object in their space, both oncoming and overtaking vehicles could take over from their meat pilots to slow down and make space for a bicyclist or pedestrian. With the push for fully autonomous vehicles, and new models advertising range-finding features, this could be a reality fairly soon. Meanwhile, most of us poor schmucks have to drive vehicles from the current fleet of rust buckets, and depend on our own poor senses to get us safely around.

Evolution could be hastened -- albeit harshly -- by equipping the newer vehicles with weapon systems that would identify and destroy older motor vehicles and their occupants, thus reinforcing the de facto minimum financial threshold for full participation in society and making the roads and highways safer at the same time. I'm not saying this is a good idea. But I guarantee that someone, somewhere, has been thinking it, along with plenty of other judgmental prescriptions for "improving" our species. Real classic antique cars would have to be equipped with transponders to mark them as better than old junkers driven by low-income dregs.

Of course in America the powers that be would rather keep requiring low income people to dig up some kind of personal transportation, preferably a junky car, than expend public monies on public transportation or alternative transportation infrastructure. There's no profit in that stuff, and profit is God.

Observation from the darkness

A few weeks ago, I observed in a post about aggressive driving in early autumn, that motorists on my route seemed particularly irritable on a small secondary road near or after dark.

Murphy's Law as it relates to motorists passing bicyclists states that the drivers will synchronize their speeds so that the pedaler and the motorists are all squeezing through the same space at the same time. In daylight this is annoying enough. At night, it is particularly hard on drivers, blinded by oncoming headlights, trying to find a safe passage. Those of us who drive, think about how often you maneuver on faith alone, because the glare has eliminated all sight of the roadway at a time when you really can't stop. Now put your pedaling self into the picture.

For the majority of situations, a decent set of lights and some added reflective material will make a cyclist adequately visible. A decent set of lights also provides enough light for the cyclist to see the road ahead. But when the road is narrow, a little hilly, and bendy, a cyclist presents much more of a challenge to drivers.

By the law, cyclists in many jurisdictions have the right to take the lane to prevent passing. This is a good idea a lot of the time anyway. It isn't always a good idea, though. You have to develop your own judgment about when to herd, and when to let 'em run.

Unfortunately, impatient local drivers will perform the most insane maneuvers to pass a cyclist, day or night, on my route. But even the ones who are somewhat more likely to take a moment will seldom take more than a moment before launching themselves around me. This factor more than any other impels me to change to the park and ride when daylight grows short. Faced with the sudden threat of each other, motorists will blame the easier target: the guy on the bike.

Is it a form of surrender, to give up the road because motorists don't have the patience and judgment to behave decently around other road users? Yes. But the death or injury of a cyclist would serve no purpose. It would not advance the point of view that motorists should learn to drive with more generosity. Someone would point that out, but it would join a jumble of other assertions that would leave us all where we started -- except for the poor schmuck who had gotten slammed by an armored vehicle.

Evolution moves slowly, on a broad front. We can each help it along in ways we'd like to see, but ultimately an individual's survival comes down to moment-by-moment combinations of skill and luck. Accumulated skill can enhance luck, but uncontrolled variables will remain. If you want to see what the future turns out to be like, you have to survive to get there.

Visibility liability: look-away lighting

On the park and ride commute on Saturday, I was riding on one of the causeways of the Cotton Valley Trail. It's dead straight, dead flat, contained between the rails, and highly popular for the morning exercise of dog walkers, joggers, strollers, and the elderly.

Up ahead, coming slowly toward me, I saw an elderly woman using a walker. We've passed before. She lives around here. She's actually a really good sport about accommodating riders. Depending on the distance between us and options for pulling off, she or I might stop. She moves v-e-r-y slowly, as you might expect.

Beyond Walker Woman my eyes were assaulted by a strobe so bright, with a flashing rate so rapid, it was like being tasered in the retinas. The rider with this light was as far behind Walker Woman as I was in front of her. We were both riding slowly. Walker Woman made the call to pull aside at a bench. I made my way carefully to her and onward toward Taser Strobe Guy. When I reached him, I remarked on how annoying his light was, but I had no time to linger and elaborate. I was on my way to work.

I wanted to ask why he felt he needed such an aggressive and hostile light on a path where he would encounter no motor vehicle traffic. I also question in general the effectiveness of a light so nasty that you want to avoid looking at it and whatever it is attached to.

A study of lighting on snow removal vehicles determined that flashing lights make it harder for an approaching vehicle to judge distance from the vehicle with the flashing light. I've also observed that the fiercely aggressive, bright flashers on emergency vehicles make it very hard to see where to go when passing through an emergency scene, even at a crawling speed. I use my flashing lights very sparingly now, and use steady mode for cruising. To be noticed and dismissed is about like not being noticed at all. A bicyclist should assume they have not been seen and plan accordingly.

If the strobe is a conscious act of aggression, I can understand it even if I condemn it. We all get frustrated at times. Some of us are frustrated at all times. But something that is of dubious value in traffic is of no value whatsoever on a separated path where you are only pissing off fellow non-motorized users.

In an added twist, Taser Strobe Guy came into the shop a couple of hours later to have us check out his rear derailleur. I did not check the bike in, but I did do the repair. I also did not preside when he picked the bike up. He had a scornful attitude toward the skill needed to adjust his shifting. I did overhear that. Maybe he overcompensates for a mechanical inferiority complex by insulting the people on whom he relies to keep his machine working. There's another poor strategy to go with his aggressive overuse of strobes.

Devise and Conquer

A bike mechanic should do more than absorb and repeat the industry's latest technical information to keep pushing the wave of product rollouts down the long shore of history. The master of the craft knows you have to deal with a lot of other stuff that washes up in front of you after drifting derelict or perhaps breeding in the depths.

A minor challenge that has bubbled up in the last decade is, "where do I put the blinky light on this bike?"

The lights themselves usually come with various mounting options. Some of them actually solve the problem effectively. But the combination of seat height, seat bags, and other factors can make the mounting more of a token gesture. Why have an in-your-face flashing light when you end up mounting it down around hubcap level?

Yesterday I had to put Superflash lights on two low-priced bikes with sprung seats and suspension seatposts. This is a combination that makes on-bike mounting difficult, especially with the trend for frames with low stand-over clearance. The suspension mechanism on the post and the thickness of the cushy saddle mean that the solid part of the seat post may be buried in the frame. Even if a bit of it shows, it may be so low that the light is practically eclipsed by the rear tire.

Your average blinky user will not clip it to their clothing. That's too much to remember. They want the light on the bike. There it will remain, while its first set of batteries dies, bursts and destroys the circuitry. So I should not care whether the light is in the best possible location. But I can't help trying to do things in a neater, more functional way if I can.

After studying the bikes yesterday I realized I could take a bolt out of the seat spring assembly on the left side and devise a mounting point that would take the seat stay clamp provided with the light.

Step one: longer bolt. The nut has a step on it which will engage the hole in a washer that will form the top of the mount.
A metal washer and a rubber faucet washer go on the bolt next.
At this stage the bracket is assembled with a section of aluminum ski pole, a bottom faucet washer, a bottom metal washer and a nut to hold the whole thing together.
Here is the light bracket in place.
It's Superflash!
And there you have it. Ready to blink.
 
The rear rack limits how low the seat can go with this rig, but that would be as true with any other seat post mount. Mounting to the seat stay just puts the light down in the ground clutter.

Not a momentous accomplishment, but a nice little craft project.

New glove design

Your faithful reporter has found this prototype of a cycling glove that puts the high viz where you can really use it.
The manufacturer's name has been obscured because they have not decided whether to release the product. Obviously it has its controversial aspects.

Uncivil Twilight

Around here, drivers seem to get more aggressive in September. This year it was a month late, possibly as a result of climate change. The increase in pushiness reinforced the second level of driver misbehavior that comes out after sunset.

When I got really good lights I tried pushing the commuting season into the months of darkness. Immediately I noticed that on certain parts of my route I could not control traffic as well as I do in the summer, even with summer's traditionally recognized heavier traffic and influx of "idiots from away." October brings the ghouls and goblins, the creatures of darkness, I guess. And a lot of them drive pickup trucks.

Fortunately, I can switch to the park and ride option, which uses mostly dirt roads and the rail trail. I've run into one or two off-season trail abusers over the years, but it's nothing like the rudeness on the road.

At different hours the mix of drivers might turn more compliant. I doubt it on the near end of my route, because night time brings out the hot rodders and tire shredders. They seem really attracted to the intersection near my house. It may be the only place for three miles in any direction where there's room to do a doughnut. Then there's a great straightaway in front of my house for the approach and the getaway.

To avoid the attention of violent redneck humorists I have gone night riding a few times around my neighborhood with only a headlight, no tail lights or reflectivity of any kind. At the first hint of an approaching vehicle I would dive for the ditch, snap off the light and freeze. If you can't be seen, acknowledged and respected, don't be seen at all. But when you do that you find out how many vehicles go by you on what seemed like a nearly deserted road. Don't be in a hurry to get anywhere.

An awful lot of human survival in general seems to depend on not meeting a psychopath at the wrong time. No strategy of defense or avoidance is perfect. And there are always the idiots.

Conditions are only slightly better driving a car in all this. You don't get more respect from other road users who are aggressive or inattentive. You just have a bit more armor plating. But the park and ride is better than no ride at all. I know its limitations.

The World is Plunging into Darkness! Prepare!

Half the world, anyway. It's called fall and winter. Daylight is below 12 hours in the Northern Hemisphere now, and shrinking steadily to the long night of the Winter Solstice. It's time to light up. Try it, you'll like it.


Dynamo lighting completes my mountain bike commuter. It opens up options for dirt road and trail cruising, too.

The rack I scavenged looks like an Axiom. It has a tail light bracket built in. It also has two savage spikes on one of the side supports, perhaps to hold a small tire pump. I've already punctured my hand, pulling the pump hose off the valve stem after inflating my tire. Before I saw those off and then discover I have a use for them I'll try sticking wine corks on them


Right after I took these pictures of the Cross Check I improved the tail light mounting with two old-style reflector brackets in place of the P-clamps I had used in the original setup. The reflector brackets hold the light more correctly perpendicular to the road. The P-clamps had a tendency to creep a little and tuck the light under, aiming it ever so slightly downward. It was visible, but its imperfection nagged at me until I found a better way.

Speaking of better ways, for the most unprotected span of wiring on the mountain bike, under the rack to the tail light, I found some clear plastic tubing to use as a conduit. I did not want to run the wire down the side rail of the rack in case I put panniers on. The top hooks would chew the wire.

Dynamo lighting is really cool. We have an account with Peter White now, so our shop can sell these fun, effective lights to our local clientele, but so far I am our best customer. I would buy at least one more set of the Busch and Muller IQ Cyo R Plus headlight and Toplight Line Plus tail light to mount on one more frame that takes 700c wheels. Then I could transfer the dyno wheel from one bike to another. I already got the spare connectors.

Hey, when the sun goes down at 4 p.m. you can stay out half the night and still get to bed at a decent hour.

Being seen

As this blonde New England princess prepared to T-bone me by running a stop sign with her shiny Volvo station wagon full of handsome family, I reflected in the moments left to me how handy it would be if I could burst into flames at will. I guess it's something like the fictional Ghost Rider, although I've never seen more than a movie promo for that.

She added extra bait for me by stopping at the sign and remaining stopped as I approached. Extra points for that.

She wasn't trying hard enough, because she failed to mow me down. She might have thought that shoving herself right up to me as I crossed the intersection -- with the right of way -- was simply an efficient use of space. Maybe in her mind, she never intended to run over me. Unfortunately, lady, I can't read your mind. What there is of it, anyway.

I've previously wished for the ability to throw showy but basically harmless lightning bolts. I still want that. But nothing expresses disdain like bursting into flames in front of someone who has just done something idiotic that put you at risk. Do ya see me NOW?!

It would be great.

OK, so it snowed


I measured about eight inches of snow at my house. Someone told me Wolfeboro logged 16. I don't know about that. Warm weather immediately started taking the cover away. Because of other necessities, four days passed before I could even think about trying to ride my dark-time path commute.

Snow survives in many shaded places. However, really shaded places didn't receive as much snow because the trees intercepted the sticky snow on the way down. The sun then melted it the next day, so it fell as warm water onto the thinner accumulation under the trees. Where we find deep drifts is in clearings that filled up, but where the low sun of late fall can't penetrate easily to bring the most warmth.



 The parking lot didn't look too promising, but I needed a ride after several days without one.


 Zoom! After the first ugly bit, the path appeared completely clear.
 Luck ran out, but for how long? I was committed to the route by then.
 This section made me work. Someone had been training a sled dog team with their off-season wheeled rig.
Woof! This was just one snowy section. I was running late, so I didn't stop to document every obstacle. Some were deeper than this, but for a much shorter distance.

The work day was pleasant and unremarkable. In addition to various employment-related tasks I also installed a helmet mount for a Beamer light to see how it might improve my lighting options.  The Black Diamond Cosmo headlamp I've been using as my "zombie spotter" is light and affordable, but I thought I might like to add a light with more range. The Beamer helmet bracket was cheap enough. I figured I could use the Beamer as my zombie spotter and the Cosmo as my dashboard lighting, aiming it down toward the computer on my handlebars while the Beamer sends its light out along my line of sight.

The term "zombie spotter" came to me as I rode alone through the spooky woods on a late October night. You know, you hear a noise from the dark forest and whip your head around to see what made it. Usually I don't see anything. Whatever might be crunching and crackling is headed away from me and that's just fine.
Zombie spotter and dashboard light

The day never felt warm, with a high in the 40s and a gusty wind, but it was above freezing. The snow had not miraculously vanished between morning and evening commute, but it was better at the end of the day. I never got sent sideways on the evening run, but I nearly did on the morning rush to town.

The augmented helmet light array picked up glowing eyes from the brimming swamp beside the path several miles out from town. If I lived in the south I would guess it was a 'gator. Up here I'm thinking it was a beaver. Can't think what else might be looking up at me from a pond when it's 38 degrees and dark. I suppose any northern aquatic small mammal is as likely. In any case it was just a glint as I hurried past. That section of the path was clear to the dirt, so I was taking advantage. No point giving the zombies a good fix on me by going slowly. I've gotten this far in life by making myself a moving target.

The Cosmo and the Beamer put out very comparable illumination. Neither one had a longer range, but they joined forces if I angled the Cosmo to place its light patch adjacent to the Beamer's. If I really want range and power from my helmet light I will have to invest in one of the modern super-lights. I don't know if I care that much. The dynamo light does a great job by itself down the road or trail.

Thinking about the hub

The dynamo hub seems like a good move to streamline my on-board light system. The bottle generator won't go to waste. It can move to the rain bike, on which I already run more rugged tires that may stand up to the wire-brush wet weather drive roller offered by Peter White.

In the world of generator hubs, the Schmidt SON seems to be the gold standard. My budget does not extend to gold, so I have to shop around. This economic fact has guided every cycling purchase since I started my adult cycling habit in college. In my racing years it was a point of pride to find cool components for your bike that looked good and functioned well for less than the price of the legendary Campagnolo. It was also great to find sweet deals on the Campy itself.

Contenders for a bargain gem in the dyno-hub market include the Sanyo H27, the SRAM i-Light and several models by Shimano.

My first impulse is to avoid Shimano. I developed that habit in the 1990s, when they were basically a malignancy in the cycling industry, spreading fast, killing other companies not just on the basis of product quality, but unfairly on the basis of size or less aggressive marketing. Their devotion to obsolescence preyed on consumers and retailers alike. Most of their stuff was not as awesome as the advertising said it was, it was merely good enough. It was shoved down the cycling world's throat on the end of a battering ram of marketing and preferential pricing for OEM spec. However, the big ugly behemoth has also continued to offer some nice basic components for those of us who like to mix, match and roll our own. You just have to remember two things: don't buy their proprietary crap that does not play well with others and stock up on the stuff you like, for the day when they quit making it at their whim.

I can get the SRAM or Shimano hubs wholesale. SRAM isn't exactly the good guys when it comes to obsolescence and tweaky innovation. They actually offer less to the tinkering cyclist than Shimano does, because their barcons are index-only. I have no brand loyalty, I have individual product loyalty. I suggest you do the same.

In the end, what matters is function for price. That's where I may have to roll the dice and do my own product testing, one wheel at a time. So it's not a question of what hub to buy, it may be what hub to buy first. Or scrape up the coin for the Schmidt, assuming the high price really does indicate the best long-term investment.

Of course I will welcome any input from users with a tale to tell. I'm not doing this right away.

It's all fun and games until you hit a skunk (and other observations from the night commute)

Chortling merrily at the power of my new light system I ventured into the deepening dusk of late October and November on the park-and-ride version of my commute. On this route I am only exposed to traffic for a couple of blocks between the shop and the beginning of the trail, and again briefly where the trail crosses Center Street. After that it's just me and the wildlife for several miles.

Regardless of apocryphal cougar sightings, none by me, my wildlife encounters have been limited to small birds at close range and some waterfowl at a distance on the sections of lake I get to see. I gave passing thought to deer, moose and coyotes. Only the moose really worried me. In some places the trail runs on a high embankment with a steep dropoff on either side into wetland. If I startled a moose on one of those I could get stomped before I could get away. They're not exactly quick-witted. But you can ride for many years without encountering a moose at all, let alone at close range. So I've felt pretty serene on my car-free private pathway.

Two nights ago, zipping along in the darkness, I rode into a fresh cloud of skunk spray. It wasn't aimed at me. It wasn't enough to leave a scent on me or my equipment. It is enough to make me peer with a bit more urgency into the shadows beside my patch of light. The whiff I got was only a warning shot. Imagine what a mess a real skunk hit would make.

Fallen leaves have also gotten deeper as autumn has advanced. They make the rail crossings harder to see, especially at night. I overshot one the other night, bouncing over the railroad ties for several bike lengths as I slowed to a stop.

The fun turns where the trail goes toward the Allen A town beach also get more interesting in total darkness. I'd been feeling pretty cocky in deep dusk, because the faint remaining light gave me a slightly wider picture. On my first run through there after the time change turned twilight into night, I found out I don't know the turns as well as I thought I did. I managed to avoid hooking a tree, but not by much.

Wednesday and Thursday nights I took Route 109 past Lake Wentworth to Bryant Road rather than stick to the possibly skunky trail through the spooky forest. A sliver of moon reflected off the smooth waters of the lake. I did have to herd traffic a little. The Superflash still smartens 'em up, but I don't think I'll make the detour a regular thing.

Herding in darkness is trickier than in daylight because I don't have full use of my peripheral vision when doing head checks at night. On Wednesday I left my helmet light on. On Thursday I turned it off because I felt it confused drivers behind me and might also blind them. Without the helmet light I no longer had light aimed where I was looking when I checked the margins of my light patch or looked for obstacles extending in from the sides. On the plus side, drivers seemed less squirrelly.

The generator is about to eat its second drive roller since I installed it. The first one probably wore prematurely because I had not dialed in the alignment perfectly. The second one lasted longer, but it's nearly gone after about a month. The alignment seemed to have drifted very slightly, but I wonder if it also wears faster because the tire is slightly irregular. The uneven pressure has a greater effect as the roller wears down.

I ordered four of them when the first one wore out. I carry a fresh one in the trunk so I can replace it anywhere. I carry spare shift cables for the same reason. I've had some very pleasant roadside breaks while replacing a shift cable. I much prefer it to replacing tires. Tire replacement is a dirtier job.

A dyno hub will alleviate this problem. It would mean building another wheel, though. I don't know how much longer I will push the commute for this year. I have enough rollers to last a while.

Turning heads

For various reasons I have made my autumn conversion from full road commutes to park-and-rides. This puts me on the Cotton Valley Trail, aka the DERT (Disappointing Example of a Rail Trail) for almost six miles each way.

The DERT was built with the rails in place. Long sections run between the rails, giving inadequate space for comfortable, safe passing when bikes meet from opposite directions. The fill varies from firm packed mineral products to loose granules that are only secure to ride on after a soaking rain gives them temporary consolidation. Numerous rail crossings challenge the rider throughout the trail's length. There have been many injuries. In spite of these statistics, the rail users responsible for its shortcomings are quite defensive of their role in its construction. Such ironies seem to make up much of life.

For me it boils down to this: I get the best use out of the path when cold weather has driven nearly all other users off it. I can deal with the crossings at my own speed and nearly never have to accommodate oncoming bike traffic. It angles away from my regular route, so it doesn't tempt me in the warmer, lighter months unless I take a fun but lengthy detour over a mostly dirt road. I used to ride that detour a lot. Now I want the time more than the pretty, traffic-free route. But in the dark and chilly end of the commuting season I can salvage bike miles and save some gasoline by resorting to the path.

Only the first mile of the ride home uses streets. For those I run the whole light array in all its flashing splendor. Once on the path, however, I don't need all the flashing lights because no motor vehicles are going to mow me down. If one does, the operator has to be pretty messed up to get on the path in the first place. The only somewhat likely candidate would be a dirt biker or someone poaching the path on an ATV.

By reducing my lights to the single head and tail light powered by the generator I present a more vehicular aspect. I've noticed cars slow way down when they're on a road that crosses the path and I'm coming up to the intersection in the dark. I wonder if I have been reported as a motor vehicle on the path. One car that slowed almost to a stop while crossing was far enough along to have passed without the slightest risk to either of us. Only the strength of my headlight drew their eye and sparked their curiosity. Coming out of a dark path where they probably expect no one at this time of year makes it particularly conspicuous.

Final modifications

I wanted to nudge the generator roller a little higher on the sidewall of the rear tire to see if it would run a little more quietly and hold up better. To do this I had to cut away some of the fender.

I had tried using files and a Dremel tool to remove some plastic. Those methods removed almost no material. Rather than use more force, sharper blades or coarser implements at higher RPMs I went to the elegant power of the light saber.

Cafiend home and shop mechanic light saber kit

The trusty Chinese knock-off of a Swiss army knife has served as my light saber many times.

Lighting it up
I had to repeat the heating process numerous times to maintain a heat level that provided a smooth cut. Light saber technology is rather primitive as yet.

The roller has plenty of clearance in this smooth arc.

Setting the generator height and angle made me scrutinize the rear rim. A telltale small hop directed my gaze to the section where a small stress crack has developed at one spoke eyelet. This is the life cycle of the modern wheel. This rim is six years old and has more than 12,000 hard miles on it. It's the third wheel on the Cross Check since I built the bike in 2000. Since 2000 I have ridden this bike more than any of my other options. The rainy-day fixed gear probably comes second.

New rim is on order. The Salsa Delgado Cross served me pretty well, but I'm liking the Sun CR 18 these days. It has a triple-box construction and is still lighter than the Delgado. They all crack eventually. We'll see how it goes.

The Courtesy Switch

On the commute this morning, once we got into town, drivers were passing too fast and too close, as usual.

I reached back and flipped the switch on the Superflash.

Instant courtesy. It was bizarre.

Big G, riding ahead of me, did not know what I had done. When we got onto a quieter street I pulled up to him and explained. I switched off the light. I don't want to waste it where I don't need it.

Look! Up ahead! It's SUPERFLASH!

Today I got my Planet Bike Superflash blinky light. I put it in the middle of the three lights I wear on my bum bag, retiring the loyal but less flashy unit that had served there for several years.

I'd been impressed by the Superflash when I saw the one on my brother's Trice this summer. In full daylight I could see the flash from as far away as I could see the trike at all.

Turbulent clouds created dramatic light effects as the sun went down tonight. Bright sun would break through to illuminate colorful leaves or white buildings, highlighting the contrast with the slate-gray clouds. As the sun dropped below the western hills, twilight advanced.

Drivers rushed past me on this Friday of a holiday weekend. Finally I got tired of it. I hit the button on the Superflash.

The result was immediate and gratifying. I could tell by the sound of tires on chip seal, and grumbling engines, that drivers were slowing down five or ten miles an hour. Almost without exception, they swung wide as well. They passed politely and sedately before resuming speed.

A few minutes later I had activated the whole system: generator light, Beamers, and the flanking blinkies.

The whir of the dynamo gets higher as my speed increases. The light becomes incrementally brighter as well, urging me to ride even harder. The beam is strong and white. It seems to intrigue drivers. The sharp power of the Superflash and the steady, relentless illumination of the generator light indicate a power disproportionate to a cyclist's size.

In a more populated area where life is plentiful and cheap, the mass of drivers would probably shove on past with their usual disregard. Around here, though, a transportation cyclist is a strange bird, worthy of a second look, especially when equipped with something better than the typical toy light. When the novelty wears off I may get less respect from drivers here, too. Right now, though, the difference is night and day.

Refinements


While I was replacing the generator drive roller I figured out how to make the tail light mounting work better. The generic seat stay clamps I'd put back there pulled the light crooked. For some reason I could not get them to bend exactly the way I wanted. I was able to adjust the angle and get a more solid mount by inserting the thinner set of spacers from a linear-pull brake pad. We've accumulated a large coffee can full of these. They come in handy for all sorts of little tricks like this.

With the generator remounted and carefully aligned, the light works better than it has since the first night. It impressed me then. Now I realize its true power.

I'm so eager for darkness to fall, I start my ride home with my eyes closed.

People perceive night riding as more dangerous than riding in daylight. With inadequate lights that is certainly true. On rural roads without many other sources of light, a good set of cyclist's lights stands out. With fewer distractions from the scenery, the night driver tends to look where the headlights point.

At intersections the cyclist's small lights may not catch the eye of an impatient motorist. Flashing modes help there, but the wise cyclist assumes no one has seen, and rides with appropriate caution. But in the darkness a cyclist can see headlights coming around bends or approaching from cross streets, giving better warning of other vehicles than we get in daylight.

Motorists react to the sight of something different. Because bicycles don't have a standard light configuration, each little variation may serve to engage the motorist's curiosity. That's probably a bicycle up there, but it could be some weird space alien thingy. You have to hope then that the motorist does not subscribe to the "kill it before it multiplies!" school of thought popular in 1950s sci-fi flicks. Tinfoil helmet covers and cheesy ray guns may buy you crucial seconds in which to make a getaway. Extra points if you ride in a closely-tailored pastel colored jumpsuit.

Those of us who pedal get treated like an alien species anyway. Our garb often inspires harsh commentary. It might as well be a space suit.

Talk about mud flaps, my bike's got 'em

Last week was not a good one for riding. I had a bad cold, so I missed the day with the nicest weather. The next two days brought nastier weather than I felt like riding in, especially finishing up in deep dusk, regardless of the lights. But I finished off the week with a ride on Saturday.

I spent a few hours yesterday getting the fenders on the Cross Check. I won't expose it to road salt, but I will have to take some rain with it if I intend to try commuting into the darker months. Either that or get a thermonuclear light set on Silver the rain bike. I'm sorely tempted. I have to pay off the first light before I can get another one.

Maybe I'll try to revive my ancient set from the 1980s for Silver. If I do that it will probably prevent me from flipping the wheel because it needs to stay in the same position relative to the generator. I would use the Sanyo bottom bracket generator, so maybe I could rig a sliding bracket. I just don't know if everything works. I'll probably just wuss out and take the car in case of real rain.

The front derailleur presses on the fender when I shift to the outer ring. It's not bad enough to prevent shifting or move the fender significantly, but it's annoying. If I space the fender back from the seat tube I can't get the rear wheel in and out of the dropouts. Mildly annoying since I tend to be a bit neurotic about function and aesthetics within my own strange standards. I hate for things to be just slapped in there. I just need to ride it to see if it will bug me.

Cross Checks are prone to toe overlap. It already made the bike a bit tricky on technical terrain. The fenders increase the overlap. I was surprised how little I encountered it on test-circles in my driveway, however. On low speed, tight turns I would have nipped the front wheel even without the fender. Again, only riding will tell me whether I can put up with it. I know how great it feels to hit a wet stretch of road and not have a spray of water and grit come squirting up all over everything.

On the way home on Saturday I discovered my generator drive roller wasn't turning consistently. The drawback to the stand light feature is that in less than full darkness you might not notice that the generator's output is repeatedly interrupted. The backup power kicks in to keep the beam shining, albeit at less than full intensity. I happened to notice the odd rhythm coming from the generator, so I stopped to investigate. The rubber roller was almost completely worn away in just a few rides. I nursed it the rest of the way home because I had to.


I believe I did not have the bracket tight enough. I was trying to keep from marring the paint too badly, using a rubber shim under the radius of the clamp. I accepted that the set screw on the inside of the seat stay would have to bite in. I hoped to limit the damage to that. As a result, the generator could wiggle out of alignment and lose contact with the tire. Or I could have a bad generator, but it will cost me another roller to find out.

I have not had the best luck with prompt shipping from Peter White Cycles. Neither of my orders so far have shipped on the day they were placed. The first order included all the equipment for the light set, so I accepted the delay. But this one is four rollers in a padded envelope. If I had planned to ride tomorrow I would be out of luck. Shipping from such a short distance definitely only takes overnight, but that's from the time it actually ships.

Fortunately the weather is supposed to be wet again and I carpool with the cellist on Wednesdays. With luck the errant rollers will have rolled in with tomorrow's mail.

Lights! Camera! Action!

As reported earlier, the light project ironically cost me the bike ride this morning.

I left the house with the bike ready to ride. I had everything I needed except sufficient time to arrive at work within even my highly flexible standards of punctuality. So when I finally got home for good at 8:30 p.m., there was plenty of darkness, and no reason not to tool up and down in front of the house to see if this rig is as good as I hoped it would be.
The generator is so much lighter and more compact than my ancient Union. The Sanyo that mounted to the bottom bracket was pretty cool, and new versions are available, but I'll probably go with a dyno hub if I move away from this sidewall model.
The tail light would not mount centered on my ancient Blackburn Expedition rack. I have an Axiom rack in my salvage pile in the crawl space, but the tail light bracket is tucked up under the projecting end of the rack. That protects the light from such mishaps as accidental breakage and possibly being seen by overtaking vehicles. Mounting this thing made me think about the problems with bike tail lights. They should really be mounted higher than any part of your average bike. Thus I maintain my large (and growing) collection of blinking lights on myself.

My two Beamer 3 headlights added useful fill light to the patch thrown by the IQ Cyo R Plus. Even without them, though, the generator light alone threw a subtly ample field of light down the road. The R version has a reflector and is hooded to direct light near the bike. This is very useful at low speeds on rougher surfaces. It still directed enough light down the road for me to feel secure in an upper-mid-range gear on this brief trial. Further supplemented by my helmet light this should be a formidable array.

LEDs don't put down the hard white light of a halogen bulb. That's what I meant by subtly ample. At first the bluish tint seems too close a kin to the navy blue of night itself. But then you realize that night has been negotiated with, rather than banished in the hard-edged way of filament lighting. I love the long useful life of LEDs and the endless energy of the generator as opposed to the helpless anxiety of fading batteries when you clearly have more ride than electricity left.

Wires present one of two drawbacks to installed on board lighting, weight and clutter collectively being the other one. I understand why sexy randonnée bikes have internal wiring. But I often think our vain habit of hiding the plumbing and wiring inside the walls of our houses is just a fussy invitation to really expensive problems when something goes wrong. I did the best I could to lead the wires simply and directly, with only sufficient slack to avoid straining splices and connections. After dark, the feeling of power and the fact that the details of the mounting are largely invisible cancel out any remaining aesthetic qualms.

I haven't put on the permanent fenders yet. I try to avoid wet weather on the multi-gear bike. Realistically, however, wet weather finds me. I also go forth on wet mornings when fair afternoons are predicted. I'm starting to view the clip-on fenders as hypocritical and insufficient. Nothing like a spatter of wet grit to remind you that the vanity of fenderlessness is not worth the crap that gets all over you and your bike.

I have to say, it was still gross cleaning the crud out of the fenders. And I had to remind myself to look at my tires when I didn't have a view of the top of them all the time.

In any case, the bike is ready to go. I can refine the setup as needed.
