Abstract
A lever driven bicycle with synchronous drive ratio control is disclosed. The lever driven bicycle may include a pair of drive levers pivotable around an axis. The lever driven bicycle may also include a force applicator connected to each drive lever, each force applicator configured to receive an application of a force to rotate a drive wheel. The lever driven bicycle may further include a control mechanism connected to the pair of drive levers, the control mechanism configured to synchronously adjust a drive ratio of each drive lever.
Claims12
A lever driven bicycle comprising:
- a pair of drive levers pivotable around an axis;
- a force applicator connected to each drive lever and configured to receive an application of a force to rotate a drive wheel;
- a force converter connected to each drive lever;
- an adjustment mechanism linked to each drive lever configured to adjust a location of the force converter with respect to a corresponding drive lever;
- and
- a control mechanism configured to adjust the drive ratio of the drive levers, the control mechanism comprising two synchronously rotatable output shafts, wherein each synchronously rotatable output shaft is linked to a respective adjustment mechanism and rotation of the synchronously rotatable output shaft causes the adjustment mechanism to adjust the location of a respective force converter.
