Rift Zone Junior 24" Bike

Marin Rift Zone Junior 24" is a proper full-suspension trail bike for young riders who want more than just casual riding. It combines a lightweight aluminum frame, 130 mm rear travel and trail-ready components to deliver control, comfort and confidence on real off-road terrain. It is a strong choice for kids and young teens progressing on singletracks and technical trails.

Marin Rift Zone Junior 24" – what it is for

Marin Rift Zone Junior 24" is a youth full-suspension trail bike designed for young riders who want to ride actual trails, not just bike paths or easy gravel roads. Inspired by the full-size Rift Zone platform, it brings real mountain bike performance to a smaller format that suits younger and lighter riders.

Its Series 3 6061 aluminum frame, MultiTrac suspension platform and 130 mm of rear travel create a bike that feels capable, stable and fun on rough terrain. Up front, the X-Fusion Velvet RLC fork with 130 mm travel helps smooth out roots, rocks and trail chatter, while the Shimano 1x11 drivetrain and hydraulic disc brakes make the bike practical and dependable for trail use.

One of the biggest advantages of the Marin Rift Zone Junior 24" is that it can grow with the rider. The frame is built around 24" wheels but is designed to fit up to 26" wheels, making it a smart long-term option for families looking for a more future-proof mountain bike.
