hello everybody, i need advice about choosing a motor for my new fatbike
short version :
just bought a fatbike with 100mm BB, want to diy electrify the bike with 48v, and i would prefer a mid drive over a hubmotor .
from all i read about it i have to chose from two options :
bbshd from bafang, -> best to choose the 120mm model and add some "spacers" to make the chainline ok without touching the frame -> great performance but expensive solution.
or
tongsheng tsdz2, much cheaper and decent performance but i can't find a stock 750w version for 100mmbb fatbikes,
- there is a fatbike moded version on an italian shop http://www.shop.future-bike.it/futurebikeshop/prodotto/active-torque-fat/ but it is a lot more expensive : 595€ for a 48v 500w 100bb (best to choose bafang then) or 89€ just for the fat bike shaft extention:
+ shipping and having to dismount/remount, ofcourse
- on aliexpress there seem to be a 100mm bb version but no info about the power (250/500/750w ?) only that it is compatible with 36/48/52v battery. see here : https://tinyurl.com/y3wrmcz3
questions about the tsdz2 and the existing 500w and 750w versions : is there a real hardware difference or is it only the setup/programation ?
if real hardware difference; is it only the controller or someting else ?
can i buy for example a 36v 100mm bb with hx18 display version and
0 -have it to run ok on a 48v battery with no modicication ? will i fry everything directly or will it run meh untill reprograming ?
1 - just "reprogram" the controller to be 750w ?
2 - buy a spare 750w? controller and just replace the original one with the remaining hardware to run ok ?
for example here : https://tinyurl.com/y5q26662 but they never tell the real power on spare controlers
should i better buy the BB 100mm 48V VLCD5 version ? no problems for custom firmware with the "old" vlcd5 ? no problems to make it behave exactly like or better than the real stock 750w version via firmware reprograming ?
the difficulties, added to the prices make me wonder if ishould not better buy a simpler and cheaper 1500w hubmotor wheel.
what would you recommend ?
thank you
