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.

Available on the Megatrail: Our mixed-wheel build, The MX Rally. Check out the details
