Kids Bike Merida MATTS J.20 (2025)
Adult riders know all too well that having the right equipment is essential to enjoying riding - so why do people accept low quality, heavy and unreliable kit for their kids? The MATTS J20 delivers the same quality ride as our adult bikes because it uses the same advanced aluminium frame technology, along with high-quality, big brand equipment such as the smooth shifting Shimano drivetrain and SR Suntour fork with custom tuned spring. 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!
