Ridgeback MX20 - 2026
The MX20 — Shift Up a Gear and Go Further
The MX20 is the perfect kids bike for riders aged 5½ and upwards who are making the exciting move to gears and going further than ever before!
With 7-speed gearing to tackle the ups and downs of both hills and energy levels, your young rider will always have the right gear for the job. Easy to adjust for a perfect fit as they grow, the MX20 is built to keep up with every twist and turn. And with grippy tyres ready to handle paths and tracks, there's no limit to where the ride might take them.
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.
Better Brakes — Brake levers are closer to the bars and adjustable for reach to suit smaller hands, and work perfectly with our smaller diameter grips.
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.
