Rigorous and fascinating investigation into the efficiency and potential surprising feature sets of completely chainless/belt-less bicycles. For example: - Infinite gear range allows optimal pedaling technique, can ensure riders are always in the perfect gear, for higher human efficiency and reduced fatigue. - Extremely advanced control system inherent to the design also allows real-time tailoring the pedaling resistance for example, detecting which leg is weaker and increasing resistance on that side of the stroke to increase training intensity for the weaker leg. - Regenerative braking might make this work with a really small battery/capacitor bank instead of a normal sized e-bike battery. Downsides mentioned: - Bicycle mechanical efficiency so bad basically necessitates a battery. (But this also allows some really cool future features!) - Control system software gets incredibly complex and doing it bad results in a terrible rider experience. - Weight (generator at pedals, motor at wheel, battery)
