Been using some bafang motors, from BBS02 750W, M600, M500, M410, M510 and now build 2 M820 system. I think for now and for me M820 is the best for riding eMTB. Less weight make different handling for thin person like me (55kg).
This are my 2 build of M820.
I'm using this 2.3 firmware on my latest build. Seems less battery consumption than my other bike on 3.2 firmware.
This is my latest build with Tantan E67 frame with 540Wh DIY internal battery.
Display shows 70km with 57% battery left. But actual distance on strava about 65km with 1100m...
Second ride 38km 597m elevation gain. Battery left 57% from 70%. So total distance with yesterday ride is 65km with 1122m elevation gain, battery left 57%. It's quite economical on battery consumption. Only using maximum of level 3 assist.
Finally I can finish my E67 build. Final weight with 540Wh DIY battery is 20kg. Little higher than expectation but with tight budget it's OK. Maybe I have to change that heavy Magic Mary tire to Maxxis Dissector to get less 600gr weight.
Today I test ride about 26km and 580m elevation gain...
from Indonesia to send back motor to China for warranty will cost about $200, not yet the shipping cost from China to Indonesia. The risk of DIY thing :ROFLMAO: :ROFLMAO: :ROFLMAO:
