<p>The invention relates to a pedal vehicle, in particular a bicycle, with a driving device which has a power-transmission device, in particular a chain, which is arranged between a pedal wheel and a driven wheel of the pedal vehicle, and with a frame. In order to improve the efficiency, a curved piece (1) is proposed which can be driven in a reciprocating movement with respect to a base part (8) fixed to the frame, and is connected to at least one foot pad (4) which is connected via a connecting rod (6) to the eccentric part of a crankshaft (9) which, for its part, bears the pedal wheel (1). <IMAGE></p> |
