Kids Bike Merida MATTS J.20 PLUS (2025)
The MATTS J20 Plus is a fat-tyred monster truck that offers the control and grip of chunky 20" oversize tyres, paired to a rigid fork that keeps excess weight to the absolute minimum. Add in our kids specific finishing kit, powerful hydraulic disc brakes and a smooth Shimano drivetrain and you’ve got an awful lot of fun without the fat. Suits heights from approx. 109-129 cm tall.
Our MATTS J range is designed for the heroes of tomorrow, which is why we put all the know-how gained from years of making adult bikes into lightweight, high-quality machines for kids to enjoy. High-quality components chosen specifically for the needs of children are married to our aluminium frames that are created with the same painstaking attention to detail and quality of finish as the rest of our bikes. That’s the only way to guarantee that young riders get the same enjoyment of cycling, safe in the knowledge that their bike will never let them down. Whatever your age, your level of ability or your size, we have the perfect first MERIDA ready for you. See you on the start line!
