depends what you use ebike for.
OCCASIONAL US3E IN SAMMER ONLY, replacement for car, riding in Canadian winter you need stuff which is reliable.
If you ride in 10 subzero you cannot stop to fasten loosened up connector or other crappy stuff like bad generic no name throttle.
USA manufacturing culture is light years above Chinese get rich fast manufacturung culture. You pay for well designed well executed smooth, no shudder, no whine like turbine , no jerking one of the best i98f no the best motor /controller in the world which LASTS, made quality metal , CNC machined with PRECISION.
Bottom line if you want reliable?
