Abstract: Various motorized mid-drive units are disclosed. The motorized mid-drive unit can be configured to drive a vehicle, such as a bicycle, having one or more cranks and a driven wheel. The motorized mid-drive unit can include an electric motor, a reducer, a gearbox (which can include one or more gears), a first one-way bearing, and a second one-way bearing. The first one-way bearing can enable power from the electric motor to be delivered to the driven wheel. The second one-way bearing can enable power from the one or more cranks to be delivered to the driven wheel. The reducer can reduce a rotational speed output from the electric motor which may be delivered to the driven wheel. The motorized mid-drive unit can propel the vehicle with the one or more cranks, with the electric motor, and/or simultaneously with the one or more cranks and the electric motor.

Abstract: A personal mobility vehicle, such as a scooter, includes at least one battery and motor for powering at least one driven wheel. The vehicle also includes a braking assembly configured to isolate the motor from the at least one driven wheel such that power is terminated from the motor to the at least one wheel in response to a user engaging a braking assembly of the vehicle. The vehicle can include a switch or position sensor that interacts with the braking assembly to initiate the isolation of the motor from the at least one driven wheel and the switch or position sensor preferably is inaccessible to the foot of the user.
