A quick release lever on the seat post raises the saddle from 19.5-in to 21.5-in in seconds, so this 14-in kids bicycle keeps fitting a 3 to 5 year old through a whole season. The tires are built in five layers, pairing a rubber outer tread with a buffer layer, cord ply, inner tube, and protective liner to shrug off thorns and glass. Two detachable training wheels let the bike run in beginner or two-wheel mode, and a hand lever plus a rear coaster brake handle stopping. Non-slip pedals, a bell, and reflectors complete the setup, and the frame ships mostly assembled with a step-by-step manual.
