Turn The Lights On!

 Today the Winter Solistice arrives at 10:59 am local (US Eastern Standard) time.  

Given that there will be less daylight today than on any other day this year, this image seemed appropriate:

It was taken during the "Glow Ride," an annual London Cycle Link event held in October.  The ride, they say, is about visibility, specifically, to "raise awareness that you can cycle in London," according to Mateus Butterwick, LCL's program coordinator.

Those riders will have even more opportunities to use their lights today than I will:  There will be even less daylight in London than we'll have here in New York.

From Watts To Lumens...To Lux

Until recently, we chose light bulbs according to watts because the wattage of an incandescent bulbs correlated to its size.  The number of watts, however, was an expression of the amount of energy it used.

During the 1980s, halogen bulbs replaced incandescent bulbs in bike lights. Still, bike lights were rated by wattage.  That designation continued even after Light Emitting Diodes (LEDs) replaced incandescent and halogen bulbs about twenty years ago.

Since LEDs use so much less energy, watts aren't a useful way to measure a bike light.  Bike lights thus came to be rated in lumens, which a measure of their light output.  (One lumen equals one candle.)  However, Kryptonite, which has just introduced a new line of bike lights, argues that lumens don't tell the story:  While a lumen count tells us how much illumination a bike light emits, it doesn't measure the effectiveness of the beam.  We want a light that allows us to see or be seen, but doesn't blind someone driving in the opposite direction.

That is why Kryptonite is rating its lights by a new unit:  the lux, which measures the illumination of a surface at a specific distance. According to the company, this measurement takes into account the quality, rather than mere quantity, of light because it takes into account how the light is focused.

Note:  I have not seen Kryptonite's new lights, so please don't take this as an endorsement of them.  However, I use, and have used, their locks.  If their lights are as well-designed, I think they'll be very, very good.

A Mission To Be Seen

Bicycles with integrated lighting systems are usually associated with touring bikes and randonneuses from the constructeurs and, to a lesser degree, high-end builders in other countries.  A few production bikes have been supplied with generators built into a bike, or more commonly, a hub, and lights built onto racks and fenders, if not the frame itself.  

Such bikes usually have wires routed into the fenders or racks so they are not only not visible, but not vulnerable to being snagged and snapped.  A few bikes have wiring built into the frame itself.

While it's nice to have lights built into a bike that's frequently ridden in the dark, they are vulnerable to theft if the bike is frequently parked on the street, particularly in the same spot.  Also, light technology has improved dramatically (though, I admit, I prefer the styling of old lights) and a built-in system might tie its rider to an inferior technology.

The latest technology in bike lights, and lighting generally, is Light Emitting Diodes (LED).  This makes smaller, sleeker and lighter (in weight as well as luminosity) units that can fit more easily on different parts of the bike.  They are as much an advance as halogen lights were when they appeared about 35 years ago and displaced the incandescent bulbs that had been in use almost since their invention. (A few lights were made with fluorescent bulbs, but the idea never caught on because they're not good at throwing a beam forward, even through a lens with the best of optics.)

Apparently, someone out in San Francisco wanted a built-in lighting system with the advantages of LEDs.  The result is that Misssion Bicycles, a local company, has just introduced a bike with LEDs built into the inside each fork blade and on the rear of the seatpost.  They are powered by a rechargable battery inside the headset that can be turned on by a cap on the stem.  Thus, the bike shares one characteristic of those custom bikes with integral lights:  wires that run through the frame.

Such a system, to me, makes sense on a bike used for commuting in an urban area.  The lights wouldn't do much to help a rider see the roadway ahead, but they will help him or her be seen in traffic--which I know, from experience, is far more useful for night riding on city streets.  And they would be more difficult to steal than other kinds of lights when the bike is parked.  The one downside I can see is that if the lights need to be replaced and a new technology displaces LEDs.

Ring Around With Bikesphere

When you're in the big city, it's all about being seen.

I'm not talking about the paparazzi spotting you in a trendy Meatpacking District bar or along a Paris boulevard--although I could be.  Rather, I am referring to cycling along a city's streets and byways, especially at night.

These days, most of us are using "blinkies" attached to our helmets, bags or bikes.  On most urban thoroughfares, brighter is better, as you want to stand out among the streetlights, neon signs and other sources of ambient urban light.  Many of us have also taken to wearing reflective vests over our clothing.  There are also all sorts of other accessories made of reflective materials we can use.

Now Michelin--yes, that Michelin--has come up with a new and possibly better way of making us more visible to drivers and others.  

Its new "Bikesphere" is a "smart" device that attaches to the handlebars.  It has light and proximity sensors that analyze what's going on around the cyclist.  If a car approaches, it laser-projects a red ring of light around the cyclist.  As the car draws closer, the projection intensifies and is more visible to both the cyclist and motorist.

This beacon is meant to show a "safe" distance between the motorist and cyclist.  According to Michelin, more than t 20 percent of drivers don't honor this distance--usually because they don't realize how close they actually are to a cyclist--and cause more than 5000 avoidable crashes every year.

In daylight, and in good-visibility conditions, Bikesphere saves its batteries and activates only its shining "position lights".

Bikesphere is the first product to come out of Michelin's Trendy Drivers movement, which crowdsources ideas and provides funding for them.  Currently, Bikesphere is not available for sale, and Michelin has not yet given as to when it might be.

Trying To Shed Some Light

Early the other morning, Daylight Savings Time ended.  That meant moving the clocks back an hour, which means that it gets dark an hour earlier.  Of course, that means day begins an hour earlier, for now.  But within a few weeks, we'll "lose" that hour, as well as an equal amount of time at the end of the afternoon, as the days grow shorter overall.

That means, among other things, that most of my rides home from work will be done in the dark.  I suspect the same is true for other commuters.  And some of us will be doing at least some part of our "fun" rides in the dark, whereas we might have been doing them in daylight a couple of weeks ago.

Many of us will therefore be using our lights more than we had been--or using them, period, after months of not using them at all.   I fall into the former category:  I don't avoid night riding; in fact, there are times I enjoy a ride begun after sunset.  However, during the weeks and months of long days, I do my nocturnal rides mostly by choice; some of the riding I'll do in the dark for the next few months will be out of necessity.

Thus, I and other riders will be making more use of our bike lights. 

It used to be that here in New York--and, I suspect, in other American cities--one rarely saw a cyclist with a high-end lighting system.  The prevailing wisdom has always said that bike lights in the city are "for being seen, not for being seen by".  Most city streets are well-lit enough that you don't need a bright headlight to see potholes or other road hazards, not to mention the traffic and turns ahead. If anything, I think that for city riding, a headlight needs to offer more side than front visibility so that drivers approaching an intersection without a signal can more readily see a cyclist approaching.  Also, I think good side visibility is useful in very tight intersections where, even if the cyclist stops well short of the crosswalk or the "stop" line, a driver could turn into the cyclist's path--or the cyclist him or her self--if he or she is not seen.

Schmidt hub generator (for disc brakes)

If anything, it always seemed (at least to me) more important to have a good tail light, preferably a good, bright "blinky".  That is assuming, of course, that you are a nice, law-abiding cyclist (which you are--right?) who always rides in the direction of the traffic.

These days, though, I'm seeing more cyclists with more sophisticated (and expensive) lights than the removable "blinkies" I use.  Some are riding with hub generators; others with rechargeable battery packs carried in water bottle cages in other attachments.  And I have seen some very high-tech looking lights mounted on handlebars, brake bolts and fenders.

Planet Bike Super Flash

Such systems no doubt have their advantages.  But, for the time being, I still prefer the Planet Bike Super Flash  I've been using on the rear and PB's Beamer for the front.  I think I've spent more on batteries for them than I spent on the lights themselves--and it's not because the lights "eat" the batteries:  the lights simply hold up well.

Planet Bike Beamer

I think I'm reluctant to buy anything more complex or costly because, well, what I have seems to have worked for me (for seven years) and because I often park where theft is a concern.  Once, when I parked my Bontrager mountain bike, someone cut the White Industries hubs out of my wheels; I worry that someone might do the same to a generator front hub if I were to use it. 

"Bottle" generator

Bottom-bracket mounted generator

Also, even though I've heard that the all of those new generators and super-lights are better than what was available before, I'm skeptical.  Perhaps it's because when I came of age (as a cyclist, anyway), most of the bike lights available were, simply, junk.  "Bottle" generators were inefficient, chewed up tires and made a lot of noise ; generators that mounted on bottom brackets and ran off tire treads also ate up tires, didn't work on treads that were too knobby or too smooth, and simply skidded over tire treads if they were covered with rain or snow.  Battery lights were heavy, clunky, mounted on flimsy brackets and put out less light than the ones powered by generators.  Really, the best light--as Tom Cuthbertson noted in Anybody's Bike Book--was the "armband" flashlight made by Wonder and a few other companies.  I used to wear one on my left leg, just below my knee, on the theory that the light bobbing up and down would signal, to motorists, that a cyclist was ahead.

Wonder "armband" light

Maybe one day, if I ever decide to build a dedicated tourer or randonneuse, I'll build a wheel around a Schmidt hub dynamo or something like it.  But as long as I have to park on city streets, I think I'm going to stick to relatively inexpensive removable lights.

A Night Ride And A Long Lunch

Today I didn't ride.  I didn't go to any museums.  I have what are, perhaps, reasons or excuses--depending on your point of view--for both.

One is that after I wrote yesterday's post, I took a late night ride into the wee hours of morning

and through a rainstorm I should have seen coming. Clouds thickened and skies darkened even before night fell; I guess I was fooled when hours passed and it hadn't yet begin to rain. 

I had just pedaled up the hill of Montmarte and was starting my descent of the Rue Ronsard when the la deluge a commence.

I zigged and zagged down the Right Bank streets and across the Pont de la Concorde faster than Lindsey Vonn on the slalom at Val d'Isere.  Then I dodged cars picking up and dropping off very fashionable (even by Paris standards) at cafes and nightclubs in the Latin Quarter.  By the time I got back to my apartment, I was soaked and giddy.  Despite the very late hour, it took me about an hour to fall asleep. 

Getting back so late from a bike ride meant, of course, that I woke up late.  It was probably just as well:  If I'd awakened earlier, I probably would have tried to do some shopping, drop into a gallery--or take another bike ride--before a lunch date with a friend I hadn't seen in eleven years. 

Even though dejeuner translates as "lunch", those two words don't mean remotely the same thing.  The French are known for long lunches during the week.  But on a Saturday that happens to be a fete nationale (L'assumption), dejeuner can fill any and all of the hours between the morning coffee and sundown.  At least, that we somehow managed to do that:  After we finished our crepes, we walked from the Montparnasse to St. Germain des Pres and St. Michel, crossing the bridge to l'Ile de la Cite (where the Notre-Dame Cathedral and Sainte Chapelle are located) into Beauborg and le Marais--stopping a couple of times along the way for coffee.

The walk was, I felt, as much a part of "lunch" as the crepes and coffee.  I wouldn't mind another lunch like it with Jay, my old friend.  I just hope I won't have to wait another eleven years for it.
 

Leaving In A Fog

She is British.  She lived her entire life in England before I brought her over in July.  So it makes sense that Vera would be accustomed to weather like we had last night.


Upon leaving work, I encountered the densest fog I can recall having seen in New York.  I literally could not see from one corner to the next, a distance of about 150 metres.  Yet, I didn't feel I had to make much of an effort to get home:  She seemed to be able to find the way.  All I had to do was pedal, and that wasn't so hard.

 

A Grand Record And, How I Became Queen of the Road

I didn't post yesterday because I was a bad girl.  I stayed up well past my bedtime and partied.  At least I rode my bike to and from the bash.


Being the warmest day we've had since October, lots of people were riding for the first time this year.  One of them, I suspect, rode this bike:

It was parked in the same rack, at my second job, where I've seen a Pinarello.  I couldn't get a better photo of it because the bikes were parked so close together.  But I think you can see that it's a nice bike:  a Motobecane Grand Record, circa 1973.

The frame was made with Reynolds 531 double-butted tubing, those nice curly Nervex lugs and Campagnolo dropouts.  The bike was originally equipped with a mixture of high-quality French components and Campagnolo Nuovo Record shifters.

This specimen still has the shifters.  However, the crankset was replaced with what looks like a late-model Sugino AT triple.  It's a fine piece of kit, and allows for a small sprocket of 24 teeth.  I'm guessing that its owner wanted a triple, which wasn't possible with the original crankset.

This is the Specialites TA "Professional" crankset, which is what originally came on the Grand Record.  A number of European bikes, including a couple of models from Raleigh, sported this fine piece of machining and polishing.  Notice that the chainrings were attached to only three arms, as was common on cranksets (including Rene Herse's) until the 1970's.  Nearly all modern chainrings attach to either five or four arms.  The newer designs are supposed to be stiffer and more secure.  That may well be true, but plenty of really strong riders rode--and even raced--on three-arm cranks.


Anyway, these days replacement chainrings for those three-arm cranks aren't available from many other sources besides eBay.


After work, I went to the party I mentioned.  A colleague was celebrating a round-number birthday; the guests included some other colleagues as well as friends of hers I'd never met before.  They were all astounded that I rode there.  "But it only took me 45 minutes," I pointed out.  


The colleague offered to let me stay at her place.  I would've accepted, except that I remembered Charlie and Max.  Did I leave enough food for them?  And how full was their litter box?, I wondered.


So I assured my colleague that I had a good time.  I think she knew that, as I was one of the last people to leave.  But I fibbed about something else:  I said I would ride my bike to the Long Island Rail Road station, which was only two blocks away, and take the train home.  


You can guess what I did instead.  I rode home, about twenty-one miles.  It's not a great distance, certainly, and as I didn't drink any alcohol (I never do.), I could easily ride in a straight line.  As it turned out, even if I couldn't, it wouldn't have been much of a problem because the roads I took were almost completely free of traffic at that hour.  

Surprisingly, I didn't feel tired, even though I started to ride at about four in the morning.  The weather had gotten chillier, but I didn't put on the tights I'd brought with me.  So I rode with my legs bare below the hem of my skirt.  I didn't feel cold; I felt invigorated.  And the full moon was so bright that, had I stopped, I could have read Ulysses.  But I didn't stop, not even for a traffic signal.  Some of them were blinking their red lights, but--OK, I was a bad girl--I ran a couple of red lights.  OK, maybe more than a couple.  If a girl runs a red light and no one's there to see it....


And, I'll admit something else:  I took some main roads on which I wouldn't normally ride.  I'm not talking about the Long Island Expressway; I'm talking about main local thoroughfares like Jericho Turnpike, Hillside Avenue and Queens Boulevard (a.k.a. The Boulevard of Death).  


As I was riding those nearly empty streets, I thought for a moment about a Pinky and the Brain episode.  In it, Brain carries out his latest scheme for taking over the world:  He gets Pinky to help him create an alternative planet Earth.  He lures people to it by offering free T-shirts, which he correctly identified as an irresistible draw.  So, emptied of its former inhabitants, Brain finally "takes over" this world.


The difference was that I didn't suffer the empty feeling Brain had in the end.  Instead, by the time I got home, I was starting to feel tired.  And I fell into a very nice sleep--after I fed Charlie and Max.

Night Commute

Today I rode to, and tonight I rode from, work--in a sundress. When I got to work, I slipped on a cardigan (which is half of a twinset) in a shade of blue like the one in the bands on the dress.


One of the things I'm enjoying about teaching an evening class is the commute home.  I'm only doing it twice a week, but it's enough to remind me of an aspect of cycling I've always loved.

Riding at night, even if only for a commute, has its own rhythms and therefore requires its own mindset.  What I've always loved, of course, is the calmness that fills the air, and me, from the time the sun sets.  I especially like it after teaching a class, which requires an energy entirely the opposite of what I feel on a ride under moonlight. Plus, as it happens, the route I took tonight (I have four different routes to and from work.) takes me through some residential areas that are possibly the most resolutely middle-class in Queens or New York City:  They are quieter than, say, the stretch of Broadway around the corner from my apartment. 


Ironically, for all that I'm praising night riding, I almost never end up riding at night by design.  It's usually been the result of working later in the day, as I am now, or of getting lost or otherwise seeing plans go awry.  One of the few times I deliberately went on a late-night ride was when I met up with a Critical Mass rally in Columbus Circle about a dozen or so years ago.   I didn't do another CM ride for a number of reasons.  For one, I'm not crazy about riding in such large groups.  And, for another, I really would prefer not to be arrested or go to jail, even if only for a few minutes.   Finally, I'm not quite certain about what organizers are trying to accomplish.


On the other hand, being out at night by choice can be enchanting, if you're in the right areas.  That happened to me during my tours in France and other places.  In particular, I think of the time I rode in circles (squares?) around Orleans and found myself pedaling ,or seeming to pedal, with the rhythms of moonlight reflected on a Loire that seemed to be just barely rippled by the breeze and in the almost silvery shadows of leaves on the vines and pear trees.


Now, I didn't see vineyards or pear trees, much less chateaux, on my ride home.  But I still had the air that was beginning to cool down after another day of 90-plus degree weather.
