Marlin 6 is the perfect ride for progressing your skills on the trails.

Integrated rack and kickstand mounts make it easy to add accessories to this versatile steed.

The 2026 Marlin 6 Gen 3 features a lightweight aluminum frame, 100mm RockShox Judy front suspension fork that cushions rocks, roots, and bumps in the trail, 10-speed fuss-free Shimano CUES shifting, and the serious stopping power of hydraulic disc brakes.

Marlin models in sizes XXS and XS have a curved top tube and lower standover height that makes it easier for smaller riders to mount and dismount
