Leading the revolution in 
trail bike freedom

As a highly refined and extremely versatile trail bike, the Megatrail is built for everything from conquering high-alpine adventures to shredding bike park laps, or just slaying your after-work rides. And when it’s time to turn the Rad up to 11, Gravity Mode™ provides a 20-second, one-bolt geometry toggle that transforms the bike into a downhill dominator--it's like having two bikes!

The Megatrail's design achieves best-in-class pedaling, next-level cornering, and downhill authority. The leverage curve works well with both air and coil shocks, providing support while pedaling, small bump sensitivity, and progression for hard bottom-out resistance regardless of shock choice. Extremely well-tuned anti-squat characteristics and mid-stroke support create a very efficient pedaling platform.

Freedom Linkage

We used our background in racecar engineering to create the Freedom Linkage, a versatile platform that gives you the freedom to tune the suspension characteristics based on your local terrain and riding style.

Alongside performance, our engineers design for refinement and eliminating unnecessary complication. This creates a platform that's made for goin' fast, yet is easy to maintain and built to last. Plus, it's built right here in our Colorado facility in the good ol' U.S. of A.
