    Abstract: 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.

    Abstract: Techniques are disclosed for a rear triangle configuration for a micromobility transit vehicle. In accordance with one or more embodiments, a micromobility transit vehicle is provided. The micromobility transit vehicle may include a seat tube, a wishbone seat stay including a fork and post connecting the fork to the seat tube, a collar connected to the post and rotatable about an axis defined by the post, and a lock cable connected to the collar to rotate about the post. The fork may be connected to a pair of chain stays, such as via a pair of rear dropouts, to extend around a portion of a rear wheel. The rear dropouts may include a vertical dropout structure and positively lock to an electric motor, such as via complementary structures. A channel may be disposed in a rear dropout to receive a motor cable running to the electric motor.
