A beautiful machine

A bicycle is an intriguing machine. It uses no form of external power, yet it propels its owner to speeds uncapable on foot. The bicycle’s passenger is its engine. It is a relatively simple machine, yet provides an efficiency unclaimed by vehicles that consume, combust, and exhaust. The bicycle provides virtually no harm to the environment. What a beutiful tool the bicycle is. As it multiplies the distance a person can travel based on a set effort, it also improves the fitness of that person.
