Let me first just say I really love this bike and in three months have put 500 miles on it. Use it to go a few miles to the train station, to the gym, and to the grocery store. It is solidly built, has great acceleration, battery life is no problem for the way I use it, braking is excellent, it can go on grass, dirt trails, sand, rough terrain, most anything, the headlight is strong and very bright, the full electric or pedal assist are great. Overall I absolutely love this bike...
