This is the children’s electric bike with two maximum settings so parents can control the acceleration to fit a child’s age. A switch on the underside allows parents to set the maximum speed at 6 mph or 10 mph, providing the flexibility for the bike to grow with the child. The 25" wheelbase provided stability for helping riders balance and the bike frame is only 3 1/2" above the ground, allowing children to easily place feet on the ground when needed. The handlebar levers provide easy access to a gentle acceleration and confident braking while the pneumatic wheels and brushed 250-watt motor combine for exciting, fun rides around the neighborhood. The bike frame is made from steel and durable molded plastic. The rechargeable battery allows the bike to travel up to 10 miles after a four-hour charge via the included AC adapter. Ages 8 to 14. 37 1/2" L x 11 1/4" W x 20 1/2" H. (33 1/4 lbs.)
