A motorized bicycle system includes an electric drive system generating a first drive torque through an electric drive motor and a mid-drive gear box system. A pedal drive system produces a second drive torque via a spindle system. A clutch system regulates the first and second drive torques to create a third output torque for driving a wheel of the bicycle. The mid-drive gear box system features a gear reduction stage with concentric gears around the pedal drive system's spindle body. Additionally, a parallel axis idler gearset includes two idler gears transmitting torque between gears of the gear reduction stage. This innovative system efficiently combines electric and pedal power for enhanced bicycle performance.
