ABSTRACT:
A power assisting device for manually operated vehicles, such as a bicycle, which takes the form of a motor which rotatably drives a driving wheel. The motor is mounted on a mounting frame. The mounting frame is connected through a linkage assembly to the frame of the bicycle. The driving wheel is connected by a suspension system to the mounting frame so that relative movement can occur between the driving wheel and the frame. The transmission of power between the motor to the driving wheel is accomplished through a pair of driving belts which are connected through an idler pulley. The idler pulley is mounted through a automatic belt tensioning device to the mounting frame.
