The core of the Specter’s power is the Bafang M620 (G510) motor, the flagship of Bafang’s lineup. The M620 motor holds a royal flush of specs: mid-drive, 1000w, torque sensor, 160nm torque, and both throttle and pedal assist. In layman’s terms, the motor has excellent balance, power, and utility, feels intuitive, and is used in high-powered cargo, mountain, and high-speed.

The torque-sensing pedal assists from the motor is a standout feature for climbing. With a press of the feet, the electric system would deliver power perfectly tailored to the pressure of the pedals. The predictability and immediacy of the torque sensor gave the perfect amount of energy in almost any condition. The match of intuition and technology makes this an excellent motor for rough and varied needs, something a cadence-based motor cannot do.
