Here's a brand new* tensioned and true wheel. Specifically using one of #Enviolo's "Heavy Duty" hubs (#N380 equivalent) that should hopefully be able to handle the output from the #Bafang#BBSHD motor.
* The hub is new, the rest of it (spokes, rim, tire, etc) are used. Here's the old wheel those parts came from, which had a #Nuvinci#N330 hub that was very broken thanks to the Bafang motor.
