Abstract
The present invention is a fully functioning two-wheel drive bicycle with a shock-absorbing front fork. The drive train which supplies power to the front wheel is incorporated into a modified frame and comprises a rear wheel driven by the traditional chain or shaft mechanism and the front wheel driven by a series of rigid shafts transferring power from the driven rear wheel to the front wheel. The drive train lengthens and shortens in parallel with the shock-absorbing front fork.
Claims14
A two wheel drive bicycle comprising:
- a power transferring mechanism;
- a frame, the frame including a head tube;
- a steering mechanism pivotably attached to the head tube;
- a rear wheel rotatably mounted on the frame;
- a front wheel rotatably mounted on the steering mechanism;
- a rear wheel drive for transmitting power from the power transferring mechanism to the rear wheel;
- a front wheel drive for transmitting power to the front wheel, wherein the front wheel drive includes at least one drive component passing at least partially through the head tube;
- and
- wherein the steering mechanism includes a suspension system for absorbing shock applied to the front wheel.
A two wheel drive bicycle comprising:
- a power transferring mechanism;
- a frame;
- a steering mechanism pivotably attached to the frame;
- a rear wheel rotatably mounted on the frame;
- a front wheel rotatably mounted on the steering mechanism;
- a rear wheel drive for transmitting power from the power transferring mechanism to the rear wheel;
