Anyone used the 1500w ebay hub motor?

People use thicker spokes for looks.

As you can tell by my builds I've never been a fan of fancy looking ebikes. TBH I am very hesitant to swap everything over to a brand new Trek 700X50C cuz the current frame is bad, busted seat tube, mis-threaded bb cup, and a funky 3rd bar in the triangle messing up my battery placement.

Might not fit on the spokes with 20" bicycle rim.

The smaller diameter the wheel the stronger it is. Ultimate durability comes from using motorcycle and moped rims which come at the cost of they are heavy. You will get less flats as the tires are thicker then bicycle tires. Motorcycle rims are smaller then bicycle rims.

Go for ultimate durability which means buy good quality components no matter which way you go.
I once had that spoke tension tool but no longer. What tension would be right though? Doubt I could even fit that tool on the little spokes

Thanks for this link and great info. Got me worried my standard 20” bmx rims aren’t going to survive 150 motor amps.

The bend of the spoke in the hole of the flange doesn’t look secure. The head doesn’t sit flush.

im working on my xf40, i can share some measurements of where my spokes bend

i think the spoke hole centers on motor are about 239.6mm straight across, my calipers dont open that wide so went from axle to spoke hole center and doubled it then minused axle diameter
dont mind the marrettes :lol:
