The Fisher-Price Rock, Roll 'n Ride Trike is a fun custom kids tricycle . It starts out as a stationary rocker trike and with a flip of the rocker base, it converts into a kids trike with a parent-controlled handle. Finally, when your child is ready, you can remove the base of this Fisher-Price Trike and it converts to a stand-alone tricycle that your child can confidently steer and pedal on his own.
