Abstract
An integrated high-performance and light-weight electric drive system for a bicycle is disclosed comprising an integrated unitary motor-controller-drive system that can be inserted into and removed from a first tube portion of a bicycle frame through an open bottom bracket shell portion of the bicycle frame. A longitudinally-extending battery pack configured to be electrically connected with and to provide electrical power to the electric motor and the controller may be configured to be inserted into and removed from a second tube portion of the bicycle frame through the open bottom bracket shell portion of the bicycle frame. Some or all of the electrical components may not be visible from the exterior of the bicycle. A unique digital torque sensing and control system is described along with regenerative braking and other unique features.
