While e-bikes might seem like a dream come true, they do have their drawbacks and limitations. Firstly, the bike is only 7-speed, which means mountain bikers riding 21-speed bikes can easily outdistance and overtake this e-bike easily. Secondly, the 30-mile charge limitation may be limiting to some bikers. This bike is also not for young children as only children 14 years and older are encouraged to ride it. Also the rider must not be heavier than 310 lbs.
