Bicycle

a light-wheeled vehicle propelled by the rider, consisting of two wheels attached to a frame composed of tubing. Between these is arranged an axle, attached to lower part of frame, to which are affixed two pedals, one on either side; to this axle is attached a sprocket-wheel over which runs an endle chain connecting with a smaller sprocket on the rear wheel. There are also chainle bicycles, in which a system of cogs takes the place of the chain. The frames are distinguished as “diamond” and “drop;” the former used by men, the later by women cyclists. The rider sits upon a saddle attached to a seat-post affixed to the frame; he there steers the machine by means of a handle-bar, which turns the front wheel in any direction required. 'The momentum of the vehicle, and the proper use of the steering bar keeps it in an upright position.
