ABSTRACT:
A motor-assisted pedal tricycle has two parallel rear wheels mounted on corresponding first and second axially-aligned axles via overriding clutches. The axially-aligned axles are connected to a differential which is driven by an electric motor, and which allows the first and second wheels to rotate independently of one another. Power may also be applied to one of the rear wheels via a pedal mechanism, which is connected to the wheel via an overriding clutch. The tricycle may be operated using pedal power and motor power independently or in combination. Moreover, the rear wheels may rotate in a forward direction independently of the differential, the motor, and the pedals when the motor and the pedals are not in use, or when the vehicle is travelling at a speed faster than that which can be attained under power of the motor and the pedals either independently or in combination.
