Rock Machine RIFF Tr 24 kids’ bike Gloss Limerock Grey is a children’s mountain bike for everyday riding both off-road and on cycle paths. It sits in an affordable performance class for riders who already care about handling, gearing, and properly functioning brakes. The 24" wheel concept is aimed at kids moving up from smaller wheel sizes to a more full-featured riding position.
The frame is made from an aluminum alloy, offering a sensible balance of stiffness and durability for kids’ off-road use. The design is based on a trail-focused kids’ MTB, where stability and control over rough terrain matter. Front suspension is provided by a Blizz 24" fork with aluminum legs and reinforced tubes. The colorway is grey, labeled Gloss Limerock Grey.
Drivetrain: Shimano SL-M315-8R shifter works with eight speeds. The Shimano RD-M310-L rear derailleur is paired with a Shimano CS-HG31-8 11–34-tooth cassette and a KMC Z8.3 chain.
Brakes: Shimano MT200 hydraulic disc brakes use Shimano ASMRT26S rotors. Both front and rear diameter is 160 mm.
Wheels and tires: One1 KTTD8F and One1 KTTR8R hubs are quick-release and have 24 holes. Rubena Cheetah 24 × 2.10 tires provide more volume for grip and smoothing out bumps.
Cockpit: One1 Alloy handlebars have 10° backsweep, 600 mm width, and 30 mm rise. The One1 MAS-MD60368 Alloy stem has a 15° angle, and the grips are VELO.
The aluminum frame delivers direct steering response, which is noticeable when changing direction in slower technical sections. The 24 × 2.10 tires boost confidence on gravel and roots thanks to a larger contact patch. Hydraulic brakes with 160 mm rotors provide consistent modulation on descents and in wet conditions. The 11–34 cassette range helps keep cadence on short climbs as well as on flat ground.
The bike is designed for kids who ride regularly and want a kids’ MTB with hydraulic disc brakes. It’s a good fit for easier trails, forest roads, and commuting, where a wider tire and a suspension fork make sense. Compared to entry-level kids’ bikes with mechanical brakes, it offers a clearer bite point and requires less lever effort.
