ABSTRACT:
An auxiliary driving mechanism associated with the front wheel of a bicycle is equipped with a pair of pneumatically actuated cylinders secured in place by a pair of spaced triangular fixing brackets and connected to the handlebar of the bicycle pivotally operated up and down by a rider's hands so as to actuate the cylinders in driving connection to the shaft of the front wheel thereof by way of sprockets and transmission devices. The pivotal handlebar of the bicycle is also coupled to the front fork by way of a head tube and a handlebar stem so that the rider can also steer the bicycle with ease and safety. Moreover, the pneumatic cylinders can also be used as pumps for inlation of the tires when necessary with the help of extension tubes.
