on simplicity in cycling

  Increasing numbers of urban bicyclists are abandoning multi-gear propulsion systems in favor of less complex mechanisms with fewer moving parts. In theory, a mechanical system with few moving parts is less prone to failure than a system with many moving parts, as the more complex system contains more elements that could fail (think of the many levers, wires, and gear-wheels on a ten-speed bicycle compared to the single gear-wheel on a child's bike). Among the individuals rediscovering the fixed-gear or single-gear propulsion system are urban bicycle messengers.

  The rugged and far-ranging operator known as the bicycle messenger traverses dozens of miles of urban landscape in varying weather conditions carrying heavy and unwieldy packages on her back. In her effort to maximize her workable hours by reducing repair- and maintenance-related down time, the bike messenger put to use one of the most simple bicycle-specific propulsion systems she could find – the fixed-gear.

  While the simplicity and reliability of the fixed-gear propulsion system has gained wide popularity in recent years, I have re-discovered an even more simple system for propelling myself forward by bicycle – by pushing off with the foot from vertical surfaces or from the ground. While perusing randomly a tome-like dictionary at Central Library, I stumbled across a picture of the early bicycle, upon which the rider moves forward by pushing off from poles, hydrants, curbstones, etc.

  In this picture we can see that the device is missing standing-fins upon which the operator might rest his feet and balance (which would be included on a modern design). There is no mechanical propulsion system, and the wheels roll freely in any direction. On the one hand, this device is merely a large, steerable scooter upon which the operator can sit; the omission of a propulsion system other than the kicking leg may be too much for the velocipedist who faces hills or whose routes lack vertical surfaces. On the other hand, urban environments are filled with vertical surfaces the operator might kick from (electrical poles, parking meters, and street signs, to name a few), and most of Earth's cities are flat and covered with layers of asphalt (which makes for a smoother ride).

  People with whom I have spoken have voiced their disdain for the fixed-gear bicyclist – they claim he has retreated too far into the bicycle's past. They deride him for seeming to have abandoned needlessly the improvements made to Baron von Drais' original design. Perhaps, however, the smog-riding bike messenger he has not retreated far enough.

  Long live the vondrais!
