A:AnswerMy son got his at 4 and outgrew it by 6. Did buy a bigger motor and upgraded the batteries as well. We have an older one that had the real shocks. These new ones don't.
A:AnswerIt depends. If he/she can ride a bike with no training wheels. Should never start a kid with training wheels anyway. A balance bike is best. Training wheels create bad habits.
Either way depending on the size of the kiddo, i would say 3 is probably to small. We got my sons his when he was 4. He is not 6 and has pretty much outgrown it.
A:AnswerBike lasts about 8-12 hours of use. Maybe less the bigger the user. It takes 12 solid hours for a full charge and battery is what is what is listed on ourchase
