Merida’s Matts J20 is a versatile kids mountain bike offering a durable and lightweight aluminum frame with reliable Shimano gearing, rolling on 20” wheels. A quality bike perfect for kids around 7 – 9 years, between 111-130cm in height. The frame is made from the same 61 Racelite aluminum as the adults’ Merida bikes, then painted and lacquered in the same professional way, so the bike still looks great even after a few years of tough knocks. The Shimano Tourney drivetrain with Revo twist-grip 1x7 speed shifting provides a modern gear ratio and allows young riders to maintain a secure grip on the handlebar with just a twist of the thumb and index fingers to shift gears, allowing them to focus on the way ahead. Short reach break levers with linear caliper brakes provide easy to service stopping power. Hidden mounts for a Carrier Rack and Mudguards maximize adaptability options and a kickstand is already included out of the box.

* All specifications listed are subject to change without notice. Please note that our specifications may be impacted by manufacturer component substitution changes caused by high global demand for bikes and resulting supply chain issues in the bike industry. We recommend confirming the specifications with your local Evo Cycles showroom if you have any questions.
Bike Weight: Many brands strive to list the lowest possible weight, but in reality weight can vary based on frame size, finish, hardware and accessories. The most accurate way to determine any bike's weight is to have your local showroom weigh it for you.
