Abstract
Electrical machines, for example transverse flux machines and/or commutated flux machines, may be configured to be coupled to an electric bicycle or other light electric vehicle. Certain exemplary electrical machines may be configured with a high torque density and/or lower operating losses, providing improved operational characteristics to an e-bike. Moreover, certain exemplary electrical machines may replace a gear cassette on a bicycle, allowing conversion of the bicycle from manual to electric operation.
