Abstract
An electrically assisted bicycle is disclosed, including a modified elongated frame, such that the storage battery and motor may be mounted at a low level between the pedals and the rear wheel for a more stable and smooth ride and to lessen the likelihood of wheel hop, and to make the vehicle easier to hold upright at rest. The motor and pedals are efficiently coupled so that either or both simultaneously may power the driven wheel; and either power source can remain stationary, causing no drag, while the other propels the vehicle.
