The 20 inch size is where a child's bike stops being a starter machine. It carries a 166 lb weight capacity rather than the 145 lbs of the smaller frames, fits a rider 55.1 to 65 inches tall with a 25 to 27.5 inch inseam, and suits ages 8 and up, so it stays useful through the years when a bike is transport rather than a toy. The frame measures 54 by 23 by 33 to 35 inches and weighs 26 pounds. Two brakes cover every situation: a hand brake on the bar and a rear coaster brake operated by pedaling backwards. A kickstand is fitted, which the smaller sizes in this line do not get, so the bike parks upright against nothing instead of being laid on its side. Note that training wheels are not supplied at this size, since a rider of 8 and up is past needing them. Tires are anti-slip rubber built in five layers, taking in a rubber outer, a buffer layer, cord ply, an inner tube, and a protective layer, which is what keeps grip and puncture resistance across wood floors, brick roads, asphalt, and cement. The seat and handlebar both adjust with a quick release lever, the saddle running 26.5 to 28.5 inches, so no tools are needed to set the fit. Comfort and visibility come from non-slip pedals, an ergonomic seat, an anti-slip grip, a bell, and front and rear reflectors. Ribbon streamers and a doll seat finish it. The frame is solid metal with rubber, PP, PVC, and TRP, arrives largely pre-assembled in Rose Red, and is ASTM and CPSIA compliant.
