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.
Claims20
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;
- and
- a pair of handles connected to the frame.

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 pair of handles connected to the frame;
- 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;
- and
- 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.
