A detachable doll seat behind the saddle gives a teddy bear or doll a place to ride along, which is often what gets a hesitant four year old back on the bike. The 16-in size fits riders roughly 4 to 7 with a saddle spanning 22 to 25 in and a handlebar at 30 to 31 in, and the frame carries up to 80 lbs Stopping happens either by hand lever or by reversing the pedals into the coaster brake. Puncture-proof wheels shrug off thorns and speed bumps, and reflectors sit on both wheels as well as front and rear. ASTM and CPSIA certified.
