Everything about the SilverRider 12-inch Trike is comfortable, so children will want to pedal for hours. The seat height makes it appropriate for children ages 3 to 5-years-old yet it is designed with thoughtful safety features to offer peace-of-mind. Who says fun and safe cannot be used in the same sentence? Spokeless steel wheels are complemented by durable rubber tires and heavy duty handgrips will not make little hands sore with extended use. The seat has a back support and nonslip surface, the pedals have no exposed hardware and it is made with a one-piece welded crank. To further reduce the risk of injury, there is a no-pinch point steering limiter. Lifetime service and replacement parts are available and it ships fully assembled with a 5-year guarantee.
