This electric bike has been a blast for my little dude. The hard thing about these kids... They grow up! He is too big to ride the bike now. Battery hold a charge and I haven't seen just degregation in the life cycle. Run times are super long! It also depends on the 3 levels and extent of the ride. We would ride the bike for 30 to 45 minutes each time we went out. The battery would last at least a week with everyday riding. Hit me up for questions.
