BICYCLE WITH FRONT AND REAR DRIVES WITH REPOSITIONED CRANKS, EXTENDED PEDAL LEVERS DRIVE

摘要

Improvements in a bicycle with four wheel drive. The front wheel drive uses arm and forearm powered system for a steerable bicycle that allows bikers to also exercise arm and forearm muscles. The drive incorporates lever fulcra located forward of the main handle bar. The main lever serves as handle grip at one end. The lever arm's length extends to the fulcrum. The rear wheel drive uses a sectorial pedal arc motion and reduces the number of leg muscles to propel the bicycle. The lever arms extend from the pedal foot pads at one end, to the fulcra located at the rear and lower (3rd) quadrant at the back of the rear wheel. The pedals rest higher above the road surface and allows a biker to negotiate over highly irregular or rough, uneven terrain with reduced possibility of pedals or rider's feet hitting ground objects.
