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.

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.

Las Bicimaquinas de Guatemala

Tourists ride "pedi cabs" and "bicycle taxis" in cities all over the world. People spin pedals in boats that are shaped like Disney characters and almost everything else imaginable.  Pizzas are delivered in contraptions that are part-bike, part-cart.  And cyclist Bryan Allen pedaled a gossamer across the English Channel in 1979.




It seems that pedal power has been used to propel humans and objects across time and space ever in just about every way imaginable. (Cycling to Mars, anyone?)  So, it's a bit surprising that more people haven't thought about other ways of using the energy people generate when they spin their feet.  

An organization called Maya Pedal has been doing just that.  Founded in 1997 as a collaboration between Guatemalan bicycle mechanic Carlos Marroquin and Canadian organization, Maya Pedal has created several "bicimaquinas" fashioned from various combinations of used bicycles and parts, wood, concrete and metal.  Each machine is handcrafted, unique and costs about $40. 



One example is this bicycle mill, fitted to a hand-powered  grinding mill or corn thresher. It can grind three pounds of any type of grain--typically yellow maize (corn), soybeans or coffee--per minute. 




Another bicimaquina looks like a stationary bicycle with a blender above its front wheel.  Actually, that's what it is. But, attached to the wheel is a rotor that substitutes for the electric motor found in the blenders most Americans use.  The faster you pedal, the faster the mixer blade--which can attain speeds of 6400 RPM--spins.

Other Bicimaquinas include  water pumps, coffee depulpers, generators, washing machines and even juicers nut shellers.  That last has proved a real boon to a women's cooperative that makes peanut butter near Sololá .  "Shelling the peanuts used to be the most labor intensive part of the business," says Maya Pedal coordinator Johanna Mesa Montuba.  "Now they just load them up in the machine and it takes a quarter of the time."  And the juicers, she says, are convenient because the women can take them to soccer games and other public events, where they can sell fresh juice.

Bicimaquinas have become popular in the Guatemalan countryside because they are cheap and easy to maintain:  no small consideration in remote areas where supplies are difficult to find and bring in.  And, if someone can't pay the full price of the machine up front, Maya Pedal will allow that person to purchase it in installments.  This is a real help to those, especially women, who want to start their own small businesses but have little or no money.

Really, what better way is there to use old bikes and parts? And to think that  I used to be so proud of myself for building "parts bin bikes"!

Power To The People: Bicycles At Occupy Wall Street

I haven't been posting as often as I had been a few months ago, mainly because my classes are bigger this year and, it seems, falls into one of two categories: those who need more and those who demand more.  I guess that's just part of being in the current economic situation.


And so is Occupy Wall Street.  I've gone to it three times and learned that bicycles are becoming an integral part of their protest, movement, or whaotever you want to call it.  That's not surprising, really, when you consider than in much of the world (and, increasingly, in some parts of the US), bikes are transportation for the "99 percent."  And, as a form of recreation, it's far less energy-intensive, and less expensive than other activities.


However, bikes are an important part of OWS for practical reasons.  Some of the protestors got there, or come and go (as I did) on two human-powered wheels.  Some of those who've stayed are transporting food and water (which, interestingly,they're getting from the taps of local homes and businesses) on bike-towed trailers or tricycles.  


But what I found most interesting of all can be seen in this photo:

Yes, this young man is powering his cell phone and laptop computer with  power he pedals into a generator.  Someone at OWS started rigging up these bicycle-powered generators after police seized the gas-powered ones they'd been using.  Now, in addition to making power for cell phones, laptops and other electrical and electronic devices, the generators are being used for a variety of milling and grinding purposes, including the making of compost, which they are using themselves in Zuccoti Park and giving to farmers who are selling fruits, vegetables and other foods in nearby markets.


While I'm on the subject,  Crowdrise, Times Up and other organizations are accepting donations of bicycles, as well as tires, tubes and other parts--and, of course, money to buy bikes and parts--for OWS.


If OWS turns into a full-blown revolution, will bicycles be credited (or blamed)?  After all, what revolves more--and is therefore more revolutionary--than a bicycle wheel?
