A study and try-out of the current available techniques for propelling bikes with electricity. This has nothing to do with my lack of car :)

Basically I want to convert a normal bike to a nice electric one, and aim to find the cheapest/easiest/most current way to do so.

Features that would be nais :

  • Regenerative braking
  • Cruise Control
  • Rear wheel propulsion, bike trailer ready
  • Gears :)

Not much in the case of innovation, but a fun project and something not many people consider to be an option.


Woop, motorkit and batteries arrived \o/.
Dropped of bicycle & motor at local bikeshop for them to respoke the wheel with motor inside. Hopefully done in ~2 weeks.

Meanwhile i'll wait for BMS before starting to make a batterypack.
