Four wheel sizes share one kids sport bicycle platform so riders can match the 12 to 18-in wheel options and saddle ranges to their height and inseam. The 14-in model supports up to 145 lbs, with a 20 to 21.5-in saddle height to help kids reach the ground. An adjustable handlebar and seat let the bike fit growing riders over time. Dual hand and coaster brakes give two ways to slow or stop, and anti-slip pedals help maintain secure footing. Detachable training wheels improve balance for beginners, while front and rear reflectors enhance visibility.
