    摘要: A variable pedal driving device for a bicycle, the device allowing the bicycle pedals to slide along crankshafts during operation of the device. Each pedal is coupled to a slide pipe slidably mounted on a crankshaft. The slide pipe is in turn connected to an eccentric member mounted on the main shaft of the driving device. When a pedal is driven in a forward direction, the eccentric member causes the pedal to extend out to a maximum distance from the main shaft, for more efficient driving of the bicycle.

    摘要: A pedal driving mechanism for a bicycle which contains structurally improved pedal arms on which pedals are installed to increase the rotary radius of the pedals during the running of the bicycle to obtain optimum driving energy with minimum physical energy consumption, wherein the structure of pedaling mechanism defines a joining line formed by the tooth-coupling of a fixing gear and a rotary gear with the axle line of a driving arm at a right angle, and the trace of the linkage formed by a connection arm and a connection link is set to move in a spiral motion forced to rotate with respect to the center of the fixing gear.
