| 摘要 |
Embodiments described herein are configured to receive forces generated by a user moving their appendages, and convert the force into mechanical force and/or energy. More specifically, embodiments may convert axial and/or tangential force into rotational force. The rotational force may be utilized to power devices, drivetrains, vehicles, such as bicycles, tricycles, kayaks, boats, etc. |
