| I bought this bike at a thrift store where I stop by every so often to buy electric scooters for a whopping $50. The batteries were bad but the bike itself is in excellent condition. The bike ran fine with the stock equipment but I wanted a full twist throttle and a true PWM controller, so I bought a Yi-Yun, which in my opinion are the best Chinese controllers you can buy. Hopefully it will have better throttle control and more power when I get done with it. I will be reverting back to 12aH batteries once I find some for cheap enough. | |
