Description

Some parts of this page are translated automatically, so please excuse any imperfections.

Rock Machine Catt JR 20 is a lightweight junior mountain bike ideal for children who want to safely explore the world of cycling – whether on bike paths, in the park, or on light terrain.

Thanks to its thoughtful construction, it combines durability, easy handling, and fun, enticing young riders to more outdoor adventures.

The frame and fork of the bike are made from 6061-T6 aluminum, which is heat-treated for greater strength and low weight.

The bike features 20″ wheels, which are the perfect size for younger riders – they are easy to handle and naturally respond to changes in direction and speed.

Reliable wheels with solid rims and quality hubs handle both city asphalt and light forest trails.

MicroShift drivetrain with 1x7 gears allows smooth shifting according to the terrain, so the child can easily tackle gentle hills and enjoy a smooth ride on flat surfaces.

Brakes provide good braking performance with sensitive modulation, which is important for safe riding and speed control even when the bike encounters uneven surfaces.
