摘要： A drive train for a human-powered vehicle comprises a drive unit, a sprocket arrangement, and a total gear range quotient. The drive unit includes a motor configured to impart propulsion to the human-powered vehicle. The sprocket arrangement is operatively coupled to the drive unit. The sprocket arrangement comprises a plurality of rear sprockets and a plurality of gear ratios respectively corresponding to the plurality of rear sprockets. The plurality of gear ratios includes a largest gear ratio and a smallest gear ratio. The total gear range quotient is obtained by dividing the largest gear ratio by the smallest gear ratio. The total gear range quotient is larger than 5.

摘要： A method for controlling electronic shifting of a bicycle includes identifying, by a processor, a torque at a crank arm of the bicycle. The processor compares the identified torque or a parameter based on the identified torque to a predetermined band. The predetermined band has an upper limit and a lower limit. The processor determines a target cadence based on the comparison. The processor determines a cadence band based on the determined target cadence. The method also includes controlling the electronic shifting of the bicycle based on the determined cadence band. The controlling of the electronic shifting of the bicycle includes actuating a motor of a derailleur of the bicycle for the electronic shifting of the bicycle when a cadence of the bicycle is outside of the determined cadence band.

摘要： Disclosed is a method for controlling power supplied to an electric drive system of an electric bicycle. The method includes determining a pedal assist power level for the electric drive system, determining a first current to be applied to the electric drive system based on the pedal assist power level, detecting a user selected boost assist at a first input while the first current is being applied to the electric drive system, and determining a second current to be applied to the electric drive system based at least in part on both the user selected boost assist and a boost trigger, the boost trigger being received via a second input.

摘要： A transmission control system is configured to be used with a human-powered vehicle that includes a crank, a first rotation body rotated independently from the crank, a drive wheel, a second rotation body rotated independently from the drive wheel, a transfer body that transfers rotation force between the first and second rotation bodies, and a transmission that controls the transfer body and shifts a transmission ratio. The transmission control system includes a motor that drives the transfer body, a first detector that detects at least one of acceleration and vibration of the human-powered vehicle, and an electronic controller configured to control the motor in accordance with a detection result of the first detector upon generation of a shift request for the transmission in a state in which the drive wheel is rotated and a rotational angle of the crank is maintained in a predetermined range.

摘要： An electric front derailleur is basically provided with a base, a chain guide, a linkage and an electric motor unit. The base is configured to be mounted to a bicycle. The chain guide is configured to guide a chain. The linkage movably couples the chain guide to the base in a forward-rearward direction to move the chain guide between a retracted position and an extended position in a mounted state where the base is mounted to the bicycle. The electric motor unit is supported on the base and operatively coupled to the linkage to move the chain guide between the retracted position and the extended position. The electric motor unit is arranged at least partly closer to the bicycle than the chain guide.

摘要： A bicycle rear derailleur including a base member, a chain guide, an actuator, and a controller. The chain guide is movably coupled to the base member. The actuator is operatively coupled to the chain guide to move the chain guide relative to the base member. The controller is electrically connected to the actuator to move the chain guide relative to the base member from a current stop position to a target-stop position. The controller is configured to change a current rear shift position corresponding to the current stop position based on a front shift position of a front derailleur.
