What
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.

Just mathed max speed (at 300 RPM as stated on aliexpress and with 0 friction or losses (unlikely))
(300*(508*3.1415)/1000/1000)*60
300 rpm 508mm wheel diameter (20*25.4)
