    摘要: A method for controlling an electric drive motor of an electrically drivable bicycle includes determining a cadence of a rider of the bicycle, and operating the electric drive motor under specification of (i) a first predefined target speed for the electric drive motor, which is lower than the cadence of the rider, and (ii) a first predefined torque for the electric drive motor, when the determined cadence of the rider exceeds a predefined cadence threshold value. The method further includes operating the electric drive motor under specification of (i) a second predefined target speed for the electric drive motor, which is higher than the first target speed, and (ii) a second predefined torque for the drive motor, when a rider torque exerted by the rider on a drive train of the bicycle exceeds a first predefined rider torque threshold value.

    摘要: A method for operating a drive system of an electric bike includes (i) increasing a motor torque generated by way of a motor of the electric bike for a predetermined first time interval, (ii) reducing the motor torque immediately after the first time interval for a predetermined second time interval, and (iii) changing a transmission ratio of a gearshift system of the drive system during the second time interval.

    摘要: A shifting device includes a transmission device, a first controller and a first communicator. The transmission device is configured to shift a transmission ratio of a human-powered vehicle. The first controller is configured to control the transmission device. The first communicator is configured to perform communication with a drive unit for a human-powered vehicle. The drive unit includes a motor configured to apply a propulsion force to the human-powered vehicle. In a case where the first controller shifts the transmission ratio. The first controller is configured to control the first communicator so that the first communicator sends first information to the drive unit in a case where the first controller shifts the transmission ratio. The first information includes at least one of information related to a shifting time of the transmission ratio and information related to a shifting period of the transmission ratio.

    摘要: A bicycle with an electric pedal assist motor capable of driving a chainring independent of cranks includes wheel speed sensors and crank cadence sensors. The wheel speed sensors and the crank cadence sensors measure wheel speed and crank cadence, respectively, and provide the measured wheel speed and crank cadence to controller of the bicycle. The controller activates motor overdrive based on the measured wheel speed and/or the measured crank cadence.

    摘要: A transmission structure of a hub motor has a hub shell, an axle, a motor unit, and a clutch assembly. The clutch assembly connects with the hub shell and the motor unit, and includes a driving ring, an output disc, a fixing base, a clutch disc, and a pressing ring. The motor unit drives the driving ring to rotate. The output disc is capable of driving the hub shell to rotate. The driving ring drives the clutch disc to rotate and further drives the pressing ring; the pressing ring then pushes the clutch disc to contact the output disc and further drives the output disc to rotate. The fixing base is magnetic and is disposed between the output disc and the motor unit. The clutch disc is magnetically attractable such that the clutch disc separates from the output disc when the motor unit stops working to prevent the motor unit from providing resistance.

    摘要: A bicycle derailleur comprises a circuit board, an electrical user interface, a motor housing, and a motor unit. The electrical user interface includes a user accessing portion configured to receive a user input. The motor housing includes a motor accommodating space. The motor unit is provided in the motor accommodating space and configured to generate rotational force and configured to be electrically connected to the circuit board. A first direction is defined from the circuit board toward the electrical user interface or from the electrical user interface toward the circuit board. The plurality of second directions is defined to be perpendicular to the first direction. The motor unit is at least partly provided between the user accessing portion of the electrical user interface and the circuit board when viewed in at least one of the plurality of second directions.

    摘要: An actuation and traction system for a pedal-actuated electric vehicle like electric bicycle, electric tricycle, or electric quadricycle comprises an electric motor, a transmission comprising an epicyclic device and a variable speed drive actuated independently of the pedals wherein the variable speed drive comprises an actuator that discretizes the ratio, and two expandable pulleys wherein the transmission of the motion occurs through a cascade of gears adapted to obtain the desired transformation ratio between the electric motor that rotates at high speed, and the pinion that actuates the chain for transmitting motion to the wheel of the electric vehicle.
