I spent 2 months researching price vs quality in the e-bike market and have found out that you don't have to settle for one or the other. The Cybertrack 300 completely exceeded my expectations on all fronts. Im 6'3" 211lbs. and still this bike performs amazingly. The delay between the throttle and response is very minimal, it gets up to 20.8 mph in about 6-7 seconds, Ive made it 23 miles using throttle only and still hadn't drained the battery completely. The pedal assist is more fun to use than the throttle and it functions great as a regular bicycle as well. It's a bigger bike too so it was able to accommodated my height and weight. Definitely a solid bike that doesn't sacrifice quality in order to be more affordable. Im Very Happy with this purchase and would recommend this bike to anyone looking to give e-biking a try.
