Realistic front and rear suspension cushion the bikes solid rubber tires over bumps. Includes stabilizer rails to help beginners learn motorcycle control. Requires four hour charge using included charger. Transmitter requires one 9-volt battery. Ages 8 and up. 16 1/2 L x 6 W x 11 1/2 H. (3 1/2 lbs.)
