Abstract
The present disclosure relates to transmission systems for vehicles and especially those for use in electric bicycles, where human power is augmented with electric motor derived power. The present disclosure includes various embodiments, where the electric motor is of the harmonic drive type and wherein there is provided a secondary axle or bracket which provides the output of the systems, driven by both the manual input and the motor input, and wherein these two inputs are insulated from one another by placement of one-way clutches, between the flex-spline and the secondary axle or bracket and between the bracket and the primary drive axle. A modular assembly for such transmission systems and a method of assembly and disassembly are also disclosed.
