Five-layer tires stack a rubber outer buffer cord ply inner tube and protective layer to resist cuts on rough sidewalks. Two removable training wheels come along for the balance stage. A front bag holds a snack instead of a basket that spills and streamers a bell reflectors and mudguards finish the ride. Seat rated to 110 lb
