  • Smart crank control for E-bike
    Patent number: 10479445
    Abstract: The bike's crank speed and crank position are sensed via a micro controller, torque sensor, gyro and accelerator disposed on the bike's crank. External power and control signals can be passed to and from the crank micro controller and the e-bike controller through a throttle connector of the e-bike controller via slip rings around the crank hub with and with pogo pin connectors connected to the respective slip rings. Throttle data can also be provided to the e-bike controller wirelessly via a wireless dongle coupled to the throttle connector of e-bike controller.
    Type: Grant
