A bicycle includes a frame, a charging circuit carried by the frame and configured to capture energy associated with movement of the bicycle, a power module carried by the frame, and a switch disposed electrically between the charging circuit and power module. The power module, in response to an indication that the bicycle is travelling downhill, closes the switch to enable energy transfer between the charging circuit and power module.

A wheel hub capable of being coupled to an axle of a wheel such that the wheel hub is rotatable around the axle. The wheel hub includes a housing adapted to be rotatably supported on the axle, a motor including a stator and a rotor, and a battery module. The stator is adapted to be fixedly connected to the axle. The rotor is connected to the housing via a transmission mechanism. Both the battery module and the motor are located inside the housing, but the battery module is placed external of the motor. Since the battery cells are located outside of the motor in the wheel hub, there is provided great flexibility to the number of battery cells installed in the power wheel.

A drive apparatus for an electric bike includes a hollow housing body, an internal ring gear fixed to the housing body, and a main shaft. At least two motor units are mounted in the housing body. Each motor unit includes a support bracket and a number of motors mounted on the support bracket. Each motor drives the internal gear through a transmission mechanism to rotate the housing body about the main shaft. The motors share one controller. Peaks of the motor cogging torque can be staggered.

Electronic bicycles may communicate with each other to provide a communal biking experience to their riders. The electronic bicycles may collect rider data about their riders and may adjust the output parameters of the electronic bicycles based on the rider data. For example, the electronic bicycles may identify a weaker rider of the riders and may adjust the output parameters of the weaker rider's electronic bicycle to minimize a difference in the operation of the weaker rider's electronic bicycle and the stronger rider's electronic bicycle. Additionally, a parent rider may establish rider restrictions on an electronic bicycle ridden by a child.

Techniques are disclosed for systems and methods associated with a micromobility transit vehicle battery connection and lock. In accordance with one or more embodiments, a micromobility transit vehicle is provided. The micromobility transit vehicle may include a frame, a battery configured to be received at least partially within the frame, and a battery lock within the frame. The frame may include a downtube having a recess disposed therein. The battery may be configured to be received within the downtube and the recess to establish a continuous surface comprising one or more outer surfaces of the downtube and one or more outer surfaces of the battery. The battery lock may be positioned within the recess and configured to engage the battery to lock the battery in place.

An electric wheel hub is provided, including: a shell; a motor assembly, including a stator, a rotor and a shaft, the stator and the rotor being received in the shell and relatively rotatable, the rotor being connected and rotatable with the shell, the shaft defining an axial direction and a circumferential direction, the shaft being movable in the axial direction and disposed through the stator, the shaft and the stator being relatively non-rotatable in the circumferential direction; and a battery unit, received in the shell, electrically connected with the motor assembly.

An electric wheel hub is provided. The electric wheel hub includes a shell, a motor assembly and a battery unit. The motor assembly is disposed in the shell and has a stator, a rotor and a shaft. The shaft is detachably inserted within the stator. The rotor is rotatable with the shell and rotatable relative to the stator. The battery unit is disposed in the shell and electrically connected with the motor assembly. The battery unit has a cartridge and batteries positionally received within the cartridge.
