This 12-in takes a 19 in to 20.5 in inseam, noticeably longer than most bikes on this wheel size, which means a tall 3 or 4 year old gets a proper fit here instead of being pushed onto a 14-in frame a year early. The saddle runs 19.5 in to 21.5 in for riders 31.5 in to 41.3 in tall, and the seat is rated to 145 lbs Tire rubber is mixed to resist cracking as well as wearing, which is what usually finishes a bike left out in the sun. Hand and coaster brakes, reflectors, a bell, and anti-slip pedals are fitted. ASTM and CPSIA tested.
