Abstract
The present invention entails a three-wheel vehicle having a main frame structure, a front wheel, a pair of laterally spaced steerable rear wheels, and a seat disposed intermediately between said front and rear wheels. A jack shaft is rotatively mounted rearwardly of the front wheel and is driven by a pedal assembly having a drive shaft rotatively journaled transversely about the axis of the front wheel. Operatively associated with the jack shaft is a multi-speed chain drive that is drivingly interconnected between the pedal assembly and the jack shaft. The jack shaft further includes an output end or side that drivingly connects to the front wheel. Consequently, it is appreciated that torque is transferred from the pedals through a multi-speed chain drive to the rearwardly disposed jack shaft and the torque associated with the output side of the jack shaft is transferred back to the front wheel for driving the same.
