Description

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

The lightweight and playful junior bike Rock Machine Riff JR 24 is designed for younger teenagers and bigger children who want confidence in rough terrain and a comfortable ride around the city.

The foundation is a 6061-T6 aluminum frame with a rigid fork, heat-treated for higher strength and durability.

The rigid Thunder 24" fork made of lightweight alloy helps keep the bike's weight low and steering precise.

Thanks to the 24" wheels, the bike is maneuverable enough yet offers better terrain clearance than smaller children's models.

The drive is designed as 1×8 speeds, which is the ideal combination of simplicity and functionality.

Braking is handled by Tektro J310 rim brakes, which are lightweight, well-modulated, and low-maintenance – the perfect solution for young riders.

Recommended child height 125 - 150 cm.
