The Radius JR Runner Bike will teach your toddler important motor and balance skills while they grow big enough for their first real Bike. The low step through alloy frame reduces weight and allows for easy mounting and confident riding; while the steel fork offers a more stable ride. The Child specific saddle optimises comfort while the child specific grips minimise hand slippage. Saddle and handlebar heights are adjustable to allow for a perfect fit and room for growth.
