Excellent bike, my kids love it!... throttle response is good, breaks are nice, very comfortable ride not just for kids, also for adults. only downside is, the lead-acid batteries are very heavy and takes 10+ hours to fully charge and of course they dies fast in about 30-45 mins of run time. The weight with the lead-acid batteries makes it a pain to lift on the front side, only a strong kid or an adult can lift the front part of the bike. rear part with the metal handle is okay to lift.
