Hello,
As my previous purchase fell through, I'm still looking for a speed pedelec. My criteria:
- cheap. second hand.
- safe
- capable of 70km one way in 0-5°C temperatures. Yes, I realise this will require about 2Kwh of battery if I want to optimise battery life.
- at least a semblance of being EU street legal, meaning speed pedelec chassis number and license plate
- ok with modifications that break EU street legality, as long as I can be reasonably certain insurance won't complain
- no drm, meaning no Bosch or other evil manufacturers
- maintainable and future proof
- as open hardware as possible
- software as free and open source as possible
That might mean I'm looking for:
- a second hand speed pedelec with EU certification and a Bafang M500 or M600 mid motor. If such a thing exists, because the only model I seem to be able to find is the Fantic Issimo, which is not what I want.
- alternatively, an existing speed pedelec with a broken rear hub motor with a fairly standard that will take a Bafang M500 or M600 mid motor. Perhaps certain older models with broken rear hub motors would work?
- a VESC based motor board like the Flipsky Mini FSESC6.7 running free/open source software
- an ESP32 based ebike controller board running free/open source software
- an ESP32 based display running free/open source software
This looks like it's the more common path taken by diy enthousiasts, so that's worth a lot to me. It's just not clear to me if any Bafang based mid-drive speed pedelecs were ever legally introduced to the EU market...
So an alternative might be:
- an older speed pedelec with Bafang rear hub motor and uart comms (quite a few cheap older EU blessed ones around)
- a spare Bafang motor with uart comms
- a lishui controller with open firmware
Thoughts? Suggestions?
Kind regards,
