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.
