Looking cool and riding with confidence is a package deal on the Piston. It features SmartStart technology: a major feat of kid-size engineering designed to outsmart physics so kids in motion stay in motion. That means kids get to focus on having a blast on their bikes. They also get a stopping option that's easy and intuitive thanks to the rear coaster brake. At the same time, a front hand-brake opens up the world of "big kid brakes." Other features include a quick-release seatpost for easy adjustment, a chainguard, and a stylish race plate to complete the look. Give your child a ride made just for them with the Piston.
