Can anyone suggest a good quality non GM controller that works with the standard GM hub motors....36V to 60V. Also can anyone confirm that the 1000W hub kit & 500W hub kit share the same hub with only an uprated controller? Both looks the same to me! Also you may like to see pic's of my new fat treads (Maxxis Hookworms 26"x2.5" High pressure 65psi to 110psi) Recommended for road going E-bikes, Nice rollers!....Cheers & good luck.
