I bought a used Ecotric Bison with 30 miles on it.
The second ride up a 1000foot steep hill the controller failed, also the phase connectors were heat damaged.
I installed a used 30a KT controller. the first ride with the new controller up a 1000foot steep hill the magnets broke free inside the motor. It made a loud scraping noise.
I have glued the magnets back in place using JB weld and epoxy thinned with acetone. the bike is working now but I do not trust it anymore!
