Golden Motor E-Bike Conversion

I converted my Costco bike to an e-bike using a Golden Motor 48V 1000W rear hub kit from Golden Motor Canada (buy from Gary at GM Canada if you want exceptional customer service!). Top speed is about 45-50km/h, although I have gone a little over 60km/h on a slight downhill. Specs: - 26“ rear 1000W hub motor - External controller - 48V 1000W 12ah lithium-ion battery - Twist Throttle, cruise control, reverse switch, horn - Top speed ~50km/h on flat, no wind, fully charged, rider 170lbs, tire
