Abstract
Abstract A power assisted pedicycle. The present invention is directed to a power assisted pedicycle such as a bicycle or tricycle. The power assisted pedicycle has a power package having a housing having therein an engine directly driving a propeller which provides motive force. A throttle control cable extends from the engine to a point on the pedicycle at which it may be conveniently adjusted.
