I've built 20 ICE cafe racers over the past 15 years but figured I'd finally dabble in putting together an electric urban toy. Here in the flat FL Gulf Coast, top speed target is around 50mph... either 18 or 20s.
Will see how well these BOMA MY1020 motors work. Pretty beefy but they could have done a more aggressive press fit of the laminations on to the axle. The magnets are retained by two flat thin steel rings so that's good, i hope. Have drilled out the end caps for better cooling. The controller is huge sadly... a lot of aluminum.
Pretty skeptical that 25h chain will handle this setup but t8f rear sprockets stop at 54T. Using a freewheel, no regen.
Still harvesting cells from Ring packs (PITA) and deciding on battery details...
