I have just about had it with this kit . When I got it the internal controller was defective . After several weeks gary convenced Golden Motors it was defective . Two months ago the bike started to cut out , the first time when I hit a bump . Then it became a regular thing . Turn it on all lights say go , twist the throttle , goes about 5 feet and cuts out . I cleaned the switch it was better but I still had to turn the switch on and off every time it cut off . I decided to replace the switch with a battery cut off switch for a boat . The switch is rated at 300A at 48v continuous . It worked one day . I spent another day checking the connections and it still cuts out . I think that I might have a bad connection inside the battery that I cannot see . Should I remove the internals and check? How do you pull out the cells to check . If this doesn't work the motor is coming off the bike and I will be peddling . At least I know I can go somewhere on my bike . One more comment , I don't go very far from my bubble and I have done the math . My truck gets 14 mpg , I use $40 worth of gas per month ,thats $480 per year . Its cheaper to use my truck than spend anymore money on more Golden Motor replacement batterys .
