Abstract: A system and method for operating a pedally propelled vehicle gear system, includes a multi-speed gear configured to provide varying gear ratios between a gear input element and a gear output element, wherein the method includes receiving a shift control signal indicating that a gear shift should be performed, providing a boost control signal to the motor to run at a boost torque bT for a boost torque time period tbT, providing a dip control signal 154 to the motor to run at a dip torque dT for a dip torque time period tdT, wherein the boost torque is higher than the dip torque.
