I bought this for my 6 year old for his birthdays some may call me crazy but he wears a full face helmet. Anyways this direct bike is made well and he has hours of fun. We get ally charge it everynight and it last the day. I would say he rides it well over an hour a day and it still have power. I have also rode it and it pulls my weight well. He has so much fun! I don't really think this product is meant for teenagers because a teenager would be to big. I can ride it but it's not comfortable. My kids 6 and 8 are the perfect size and have a blast.
