Love the Monster Trucks Custom Shop? Then get ready for some 2-wheeled fun. The Racer Bikes Design Shop allows you to customize cool street bikes with an assortment of stickers and metallic paints. After the bikes are fully created, rev them forward a couple of times, press down on the riders' helmets and watch them race! Set includes two 51/2x 4 bikes with molded riders. Ages 5 and up.
