Abstract
A system is provided for shifting gears in a cycle. The shifter system includes a motor that delivers a torque to propel the cycle. A variable ratio transmission is coupled with the motor. A cable transmits movement to shift the variable ratio transmission. A cable pulley is connected with the cable and is rotated to move the cable. A lever is coupled with the cable pulley and imparts rotation to the cable pulley. A sensor is positioned to detect an initial input on the lever that does not rotate the cable pulley. A controller interrupts the torque from the motor in response to the initial input and prior to a shift in response to the transmission of movement by the cable.
