摘要： Techniques are disclosed for systems and methods associated with a powertrain for a micro-mobility fleet vehicle. The fleet vehicle may include at least one drive wheel to provide tractive contact between the flee vehicle and a road surface, an electric motor mechanically coupled to the drive wheel and configured to provide motive force for the fleet vehicle, a brake resistor configured to provide dynamic braking of the motor, and a motor controller electronically coupling the brake resistor to the motor. The motor controller may be configured to control the motive force provided by the motor using the brake resistor. The motor controller may be configured to limit a speed, power, and/or acceleration of the motor using the brake resistor based on an operational environment of, and/or on a directive received by, the fleet vehicle. The brake resistor may provide a relatively wide range of traction control for the fleet vehicle.

摘要： A bicycle drive unit includes a planetary gear mechanism, a first motor and a power switching mechanism. The planetary gear mechanism includes an input body, an output body and a transmitting body. The input body receives a rotational input of a crankshaft. The output body outputs the rotation of the planetary gear mechanism to the outside. The first motor controls the rotation of the transmitting body. The output body rotates in a direction corresponding to a first rotational direction when rotation in the first rotational direction is input from the crankshaft to the input body. The power switching mechanism rotates the output body in a direction corresponding to a second rotational direction when rotation in the second rotational direction is input from the crankshaft to the input body.

摘要： A brake system for a bicycle includes a number of brake members constructed to engage one another, such as a rotor and a shoe or pad. At least one of the brake members includes fiber reinforcing members. The fiber reinforcing members are distributed throughout the brake member and communicate the braking loads across a substantial portion of the brake member. The braking member is further constructed to distribute the heat associated with a braking action in a generally uniform manner across the brake member. Preferably, the brake member is formed with carbon-type fibers suspended in a Bismaleimide type material. Such a construction provides a powerful, lightweight and robust brake system.
