Ridgeback Dimension 16 - 2026
For young pedallers aged 3½ to 6 years old, the lightweight Dimension 16 is a compact package of fun that builds real riding confidence from the very first pedal stroke!
Easy to adjust for a perfect fit as they grow, the Dimension 16 is built to keep up with your little rider every step of the way. A handy chain case keeps everything tucked neatly away — no messy chain, no fuss — while easy-rolling tyres help young adventurers make smooth progress along paths and tracks with confidence.
Easy-Pedal Cranks — Our pedal cranks are ergonomically correct, proportional to the child's leg length. They also place the pedals closer to the bike's centre so that children can pedal as smoothly and naturally as possible.
Smaller Grips — Our handlebars and grips are narrower diameter so they fit small hands better, for confidence and control as well as better ability to reach the brakes safely.
Faster Tyres — Special edition Nutrak Speedsters with puncture resistance roll comfortably and smoothly.
Lowered Frames — Our frames are lower where it counts, making it easier to get on and off and increasing clearance for greater confidence.
Steering Limiter — To help prevent falls when learning to co-ordinate pedalling and cornering, the steering has a limit stop that helps avoid an over-steering situation.
