Rock Machine RIFF Tr 20 kids’ bike Matte Deep Ocean Blue is a children’s mountain bike designed for off-road riding and family trips. It’s built around a durable aluminum frame and a simple seven-speed drivetrain. The spec targets the affordable segment, where function, low-maintenance service, and the right wheel size are what matter.
The frame is made from 6061-T6 aluminum with heat treatment, which supports stiffness and long-term durability. The geometry matches a kids’ MTB with an emphasis on stability and easy tracking. Up front, a rigid Alloy Custom Tubing fork reduces weight and simplifies maintenance. The Matte Deep Ocean Blue colorway falls within the blue range and improves the bike’s visibility in traffic.
Drivetrain: microSHIFT DS45-7R shifter controls 7 speeds and works with the microSHIFT RD-M21SS rear derailleur. The Shimano CS-HG200-7 cassette offers a 12–28-tooth range, and the chain is a KMC Z8.3.
Brakes: The Tektro MDM 280 brakes are rim brakes, aimed at straightforward servicing. The controls are set up for smaller hands, and modulation is predictable at lower speeds.
Wheels and tires: The wheels are 20" and are built on Stars J19SD rims with 24 holes. Rubena Cheetah 20 × 2,10 tires add volume for traction and cushioning on gravel.
Cockpit: One1 Alloy MTB AL-153BT handlebars and the One1 MAS-MD60368 Alloy stem hold an MTB position with good control. A Selle Royal Junior saddle is paired with a One1 Alloy 27,2 mm seatpost and VELO grips.
The combination of an aluminum frame and a rigid fork transfers pedaling power without unnecessary losses, which you’ll notice on flats and mild climbs. The 2,10-wide tires increase stability and help on roots and loose gravel. 24-spoke rims and quick-release hubs make servicing and tube changes easier. The seven-speed range with a 12–28 cassette supports a steady pace on bike paths and in light off-road terrain.
The bike is intended for kids moving up to a 20" MTB and wanting to ride off the pavement. You’ll appreciate it on trips with parents as well as on gravel roads, where handling and simple operation matter most. In concept, it matches kids’ hardtails with a seven-speed drivetrain and a rigid fork.
