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.

Disclamer: Height is a good general guideline to discover the appropriately sized frame, but bear in mind that it is only the first part of the bike fitting process; please also note that your inseam length and arm length will play a big part in your overall comfort. Other factors to consider are your torso length, lower back and hip flexibility, preferred riding position, core muscle strength, and experience with riding. All of our Bike Barn stores are qualified to help perform a bike fitting for you - stop in for a checkup if you are looking to upgrade your comfort level!
