The 20-in size sits at the top of this range and ships without training wheels, because a rider on a 55.1 to 65 in frame has already learned to balance. Seat height runs 26.5 to 28.5 in for a 25 to 27.5 in inseam, and a quick-release lever changes it without tools. Capacity on this size is 166 lbs A hand brake and rear coaster brake both stop the bike, and a kickstand parks it. Tires use five layers of rubber, cord ply, inner tube, and a protective layer. Reflectors, a bell, and a front basket come fitted. ASTM and CPSIA compliant.
