Hey there! Nice work, looks great! I've built a few of these and the biggest concern with those motors (I've tried them before) is that they aren't made to handle the torque of even small hills. They'll burn out on mile 25. It's not the wattage that's the problem, they just start to slip and burn out unless you gear them down a lot, but then you lose a lot of their speed. Maybe I've just always bought cheap stuff. Also worried about the tension on the chain, is it adjustable? I also had trouble with XT90 in the past. I would melt them. Proper soldiering iron fixed that. Nice build! It's super unique!

To get up steep hills, you need not only a powerful motor, but also chains and gears to handle that power:

Sure, for these absurdly powerful e-moped conversions. But even ordinary bicycle chains need to be able to handle 1000W, which is more than the vast majority of ebikes.
