Abstract
A bicycle comprising a front wheel and a rear wheel supporting a frame. A bottom bracket of the frame defines a first axis, a second axis and a third axis. A pedal crank assembly is supported for rotation about the first axis and includes a first driven gear and a first drive gear. A second gear is supported for rotation about the second axis. A third driven gear and a third drive gear are supported for rotation about the third axis. An electric motor drives the first driven gear and the first drive gear rotates in response to rotation of the first driven gear. The first drive gear engages and rotates the second gear, which drives the third driven gear. The third drive gear rotates in response to rotation of the third driven gear. The third drive gear is rotationally coupled to the rear wheel.
