Abstract
A weight-bearing device includes a single wheel, a frame attached to the wheel, and an electric motor attached to the frame. The electric motor is configured to rotate a first gear, connected to a second gear with a chain. The second gear is connected to the wheel. The second gear and the first gear may have a gear ratio of greater than 8:1.
Claims21
A weight-bearing device comprising:
- a single wheel configured to contact the ground;
- a motor having a power source and an output shaft;
- a first gear rotationally fixed to the output shaft;
- a second gear connected to the single wheel with a unidirectional torque transfer device, the second gear and the first gear having a gear ratio greater than 6 to 1;
- a chain between the first gear and the second gear;
- a frame including a weight-bearing surface tangential to the single wheel, the frame connected to the single wheel;
- a pair of handles connected to the frame, the pair of handles including:
- a first climbing handle connected to a first terminal end of the pair of handles and oriented approximately perpendicular to one of the pair of handles;
- and
- a second climbing handle connected to a second terminal end of the pair of handles and oriented approximately perpendicular to another of the pair of handles;
- and
- a twist throttle configured to control the motor.

A weight-bearing device comprising:
- a single wheel having a hub radially centered in the single wheel, the hub having a hub first end and a hub second end;
- a frame having a frame first side and a frame second side, wherein the frame first side is connected to the hub first end and the frame second side is connected to the hub second end, the frame being rotatable relative to the single wheel and including a weight-bearing surface tangential to the single wheel;
- a handle assembly, including:
- a handle support connected to the frame;
- a first handle attached to the handle support, the first handle having a first terminal end;
- a second handle attached to the handle support, the second handle having a second terminal end, wherein the first terminal end is separated from the second terminal end with a gap;
- a first climbing handle connected to the first terminal end and oriented approximately perpendicular to the first handle;
- and
- a second climbing handle connected to the second terminal end and oriented approximately perpendicular to the second handle;
- an electric motor mounted to the frame;
- a first gear configured to be rotated by the electric motor, the first gear having a first tooth count;
- a second gear connected to the first gear by a chain, the second gear connected to the single wheel with a unidirectional torque transfer device, the second gear having a second tooth count, wherein the second tooth count is at least 8 times greater than the first tooth count;
- and
- a twist throttle configured to control the motor.
