The Motor System
The mid-drive motor constantly samples relevant information at a frequency of up to 80,000 Hz via a torque sensor and two-speed sensors. The resulting data on crank torque, vehicle speed and the speed of rotation of the pedals is made available to the controller, ensuring precise control of the vehicle while achieving the highest possible efficiency. The Ultra Drive System puts the rider in complete control. In spite of a generous power output and a maximum torque of more than 160 N.m, the motor operates in virtual silence. The modular motor design and integrated controller make disassembly easier and improve service responsiveness.
The high-contrast LCD display delivers all important information at a glance and can also be read in direct sunlight without difficulty. The BAFANG handlebar controller gives good feedback, is extremely robust and easy to use. The additional output can be individually controlled by five support levels. The user interface is clearly legible and intuitive to use. This display is protected against contact and ingress of water and dirt and complies with protection class IP 65.
