Abstract: Provided is a freehub torque and speed sensing device, including a freehub, a dynamic assembly and a static assembly. The freehub includes a freehub body (2) and a freehub fixing housing (1) sleeved on an outer side of the freehub body (2). A load connection portion (204) is disposed at one end of the freehub body (2). A torque sensing deformation unit (203) is disposed at the freehub body (2) adjacent to the load connection portion (204) and includes at least one sensor. The dynamic assembly rotates with the freehub body (2). The static assembly is fixedly connected to an external fixing structure body and includes a primary control unit. The dynamic assembly includes a secondary control unit electrically connected to the sensor. A torque signal is transmitted between the primary control unit and the secondary control unit in a wireless manner, and the primary control unit supplies power to the secondary control unit in the wireless manner. In this manner, the whole vehicle assembly is more convenient and safer, and the signal stability is high.

Abstract: An electronic bicycle includes a torque control system that controls what torque is applied to wheels of the electronic bicycle by electronic hub motors. The torque control system may determine a torque to apply to the wheels based on user input signals. The torque control system also may detect when the wheels of the electronic bicycle are slipping, and adjust the torque to minimize the time that the wheel is slipping. Additionally, the torque control system may determine a coefficient of friction between the wheels and the ground and determine a maximum torque to apply to the wheels based on the coefficient of friction. Furthermore, when braking, the torque control system may determine whether torque is applied to the wheels by passive braking or by active braking.

Abstract: A hybrid pump-action vehicle and therapy device may include a pumping arm attached to a lower pump-action assembly. As the pumping arm is actuated, the lower pump-action assembly moves forward and rearward in response to the pumping action and powers movement of the vehicle. The lower pump-action assembly may be releasably connected to the pump arm so that the pump arm can be disengaged from the pumping action but still be usable for steering. A motor may also be provided to provide assistance or full power to the vehicle based on a user-selectable amount of assistance. And finally, the vehicle may be configured such that it can be collapsed to a fraction of its operating footprint to enable easy transport and storage.

Abstract: A coaxial mid-drive power device of a bicycle includes a reducing structure and a hollow shaft motor engaged with the reducing structure that are disposed in a motor base. An output end of the reducing structure is operatively coupled with a one-way bearing bracket with a sprocket base via a one-way bearing. A crank spindle engaged with the one-way bearing bracket through another one-way bearing penetrates through the motor base. The two one-way bearings respectively have opposite rotation directions and are respectively located on different sides, i.e., an inside and an outside, of the one-way bearing bracket. A strain gauge disposed on the crank spindle is electrically connected to an annular conductive rail assembly engaged with the crank spindle and an elastic sheet assembly on a control circuit board in the motor base, hence the strain gauge could directly obtain a change in a torque of the crank spindle.

Abstract: An electric assist vehicle is described, which may have a cargo area, a drivetrain including an external crankset and an electric motor, and a speed control system. The speed control system automatically limits the maximum operating speed of the vehicle based, at least in part, on a load mass (e.g., a gross weight) of the vehicle and/or the cargo area of the vehicle. Limiting the speed includes, for example, reducing the power of the electric motor and/or increasing a braking force on the vehicle.
