Abstract: A motorcycle has a frame assembly including a main frame supporting front and rear wheels on a central line thereof. A connecting member is mounted on the main frame between the front and rear wheels, and a subframe is mounted on the connecting member and is capable of banking laterally about the connecting member. At least one of the front and rear wheels is a drive wheel. At least the drive wheel is capable of preventing the main frame from banking laterally. Centrifugal forces generated upon cornering are counterbalanced by centripetal forces produced when only the subframe banks laterally. The drive wheel supported on the main frame which does not bank has an increased road gripping force. Thus, high-speed cornering is made possible.

Abstract: An electric drive unit for vehicles which are normally rider propelled, such as bicycles and tricycles, has a wheel driven by an electric motor for propelling the vehicle by frictional engagement with the front wheel tire. A control lever mounted on the handlebar is manually actuated to exert a pull on a cable which is slidably encased in a flexible sheath which is incapable of contracting. A support for the lever provides a fixed abutment for an upper end of the sheath, so that the motor mounting bracket, against which the lower end of the sheath abuts and which is yieldably supported, is displaced downwardly, by distortion of the sheath, to move the friction wheel into engagement with the vehicle tire.
