The Max Mid-Drive Motor by Bafang and its torque sensor constantly measures how hard you pedal and calculates the level of assistance. The motor provides more assist the harder you pedal, and less assist the lighter you pedal. Its on-demand acceleration makes you turbo through traffic. Its power can be used to tackle climbs with gradients up to 25% without any effort. In spite of generous power output and a maximum torque of more than 80Nm (among the most powerful on the market), the motor operates in virtual silence. The Bafang Max Drive System has a 250W motor. It’s extremely silent, almost unperceivable. A torque sensor and two-speed sensors transmit data to the controller with an 80k Hz frequency, allowing a fluid and precise ride.
