Please tell me what do you think about that setup, I’m starting to build my own mountainboard, has to have speed and range, below I created a part list, is mainly Chinese, but I guess is worth using, at least some of this parts
if you are looking at doing a chain drive system you could have a look at sprockets and chains on https://www.gearsandsprockets.co.uk/ i’ve found these guys to be a one stop shop for this type of stuff.
probably want a 04b chain and sprocket to go with it, would have to ask around about chain on mountain boards as i have no experience with building them.
You need to balance kv and voltage to get you good speed and torque balance.
The difference is that the vesc 6 uses better hardware and is more reliable at higher voltage. It also has higher current abilites which you really need for a mtb
