The core of the Specter’s power is the Bafang G510(M620) motor, which itself is the flagship of Bafang’s lineup. The G510 motor holds a royal flush of specs: mid-drive, 1000w, torque sensor, 160 N.m torque, and both throttle and pedal assist. In layman’s terms, the motor has great balance, power, utility, feels intuitive, and is used in high-powered cargo bikes, mountain bikes, and high-speed bikes alike.
The torque-sensing pedal assist from the motor is a standout feature for climbing use. 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 delivered the perfect amount of power in most any condition. The match of intuition and technology make this an excellent motor for rough and varied conditions, something that a cadence-based motor simply cannot do.
