The chain cover on this 14-in kids bike is clear, so a 4 year old can watch the chain and sprocket turn while fingers, laces, and pant cuffs stay outside of it. Underneath sits a familiar learning kit: a hand lever at 30 to 31 in high, a rear coaster brake, and two side wheels that unbolt when they are no longer wanted. Silver paint hides scuffs better than a bright finish, and the cushioned saddle slides from 20 to 21.5 in for riders 37.4 to 43.3 in tall.
