Abstract
A bicycle includes: a frame that supports a front wheel and a rear wheel; a pair of up-and-down links that are respectively provided on a right side and a left side of the frame in a front view; a pair of pedals that are respectively supported by the pair of up-and-down links; and a drive unit that drives the rear wheel. A front end of each of the pair of up-and-down links is pivotally attached to the frame, and a rear end of each of the pair of up-and-down links is respectively connected to each of the pair of pedals. The drive unit includes a pair of crank arms that are arranged point-symmetrically at an angle of 180° in a front view, and a force that depresses each of the pair of pedals so that the pair of pedals alternately swing is transmitted to the pair of crank arms through the pair of up-and-down links. The bicycle further includes a horizontally-holding mechanism that holds each of the pair of pedals approximately horizontally while rotating of each of the pair of up-and-down links.
