Abstract

The present invention relates to a bicycle including: a frame for disposing a front wheel spaced apart from a rear wheel; a rotary shaft rotatably arranged in the frame; a pair of pedals for rotating the rotary shaft; a rear wheel shaft rotatably installed in the frame, and having the rear wheel mounted thereto; and a pair of transmission devices each of which has a driving sprocket mounted on the rotary shaft, a slave sprocket disposed on the rear wheel shaft, and a chain for interconnecting the driving sprocket and the slave sprocket. As the bicycle of the present invention is provided with a pair of transmission devices for transmitting power via the pedals, the bicycle may run via one transmission device even upon the occurrence of a breakdown of the other transmission device.
