A 16-in kids bike for a rider 41.3 in to 51.2 in tall with a 20 in to 22 in inseam, on a saddle that travels between 21.5 in and 25 in The front hand lever exists for managing pace down a gentle slope, not only for coming to a halt, which is where speed control gets learned before a real hill makes it urgent. Back-pedaling grabs the rear wheel as the second option any time a hand leaves the bar. Textured air tires hold damp pavement, a thumb bell and reflectors sit at both ends, and the seat is rated to 110 lbs Training wheels detach when balance arrives.
