Abstract
A multi-speed system configured to increase the speed or decrease the pedaling effort of a lever propelled bicycle. The multi-speed system is composed of a manual control device 70, mounted on the frame close to the rider's hand placement on the handle bars, and other connected components configured to change wheel rotation per pedal. It has the ability to transfer manual force to the transmission means to change propulsion speed and effort. Depressing a control lever 2 down will allow the rider to increase in speed and lifting the control lever 2 up would allow the rider to decrease pedaling effort.
Claims1
A lever propelled bicycle with a tubular symmetrical frame, wherein the lever propelled bicycle comprises:
- A lever propelled bicycle with a tubular symmetrical frame, the bicycle comprising:
- right and left lever machines, wherein each of the lever machines is “L” shaped and has a shorter side in a generally vertical position and a longer side in a generally horizontal position when the lever machine is at a lowest rotated position and wherein each of said lever machines has a fulcrum near an upper end of the shorter side;
- a first linear transmission means connected to the shorter side of the right lever machine and a second linear transmission means connected to the shorter side of the left lever machine;
- said first linear transmission means operable to pull with rotational force a connected rotational drive component within a respective right upright tube member of said bicycle to rotate a coupled rear wheel in a forward driving direction and said second linear transmission means operable to pull with rotational force a second connected rotational drive component within a respective left upright tube member of said bicycle to rotate the coupled rear wheel in a forward driving direction.
