Abstract

Abstract A two-wheeled toy vehicle including a wheel drive motor and capable of maintaining an upright position during operation without the assistance of a third wheel or the like. The exemplary embodiment is configured in the form of a motorcycle and includes an electric drive motor and batteries therefor located below the axis of rotation of the wheels to provide the vehicle with an extremely low center of gravity thereby enhancing its stability during operation. The vehicle can be operated as a free running vehicle or, in the alternative, can be provided with a tether of variable length and with a variable speed control, both of which can be controlled by a user during operation of the vehicle.

Claim 11
Dependent Claim 71 words
The vehicle of claim 8 further including a pair of means, one on the underside of each of said battery receiving means, and normally elevated above the surface on which the vehicle may travel for engaging the surface on which the vehicle is traveling when the vehicle tips a predetermined degree for rebounding therefrom to move the vehicle to an upright position thereby maintaining stable operation during movement of the vehicle.
Claim 12
Dependent Claim 107 words
A two-wheeled vehicle comprising: a. a vehicle frame; b. a front wheel rotatably mounted on said frame; c. a rear wheel rotatably mounted on said frame; d. an electrical motor mounted on said frame connected to said rear wheel to rotate the same; e. a battery housing mounted on said frame in a rearward position on said frame above the axis of rotation of said rear wheel; f. whereby when a battery is received in said housing said vehicle has an extremely rearwardly located center of gravity so that torque applied to said rear wheel by said motor will cause the vehicle to do a wheel stand.
Claim 13
Dependent Claim 107 words
A two-wheeled vehicle comprising: a. a vehicle frame; b. a front wheel rotatably mounted on said frame; c. a rear wheel rotatably mounted on said frame; d. an electrical motor mounted on said frame connected to said rear wheel to rotate the same; e. a battery housing mounted on said frame in a rearward position on said frame above the axis of rotation of said rear wheel; f. whereby when a battery is received in said housing said vehicle has an extremely rearwardly located center of gravity so that torque applied to said rear wheel by said motor will cause the vehicle to do a wheel stand.
