Suspension Like No Other
High main pivot gives it a bump-swallowing rearward axle path. The Guidler pulley kills the pedal kickback of high pivot systems. The 4-bar linkage keeps braking smooth, traction high and pedaling crisp.

Descend into Greatness
It’s a hell of a climber but come on. Jekyll was born for the downs. Every part of it crafted for the sweet embrace of speed, every element designed to help you wring a bit more of velocity’s nectar from those steep, chunky, high pucker lines you love.
Best. Suspension. Ever.
4-bar meets high pivot meets idler pulley meets size-specific kinematics. For real. If you’re not up for suspension buzzword bingo, just know that it grips, floats, and pedals like nothing else. It’s always up for getting down.
The Gravity Cavity
The shock tucks cleanly into the twin spar downtube, keeping the bike's center of gravity as low as possible. Wicked stability, instant line changes and one-of-a-kind looks.
Built for You
Well, not you specifically. But someone just like you. With our Proportional Response design, everything - from the suspension layout to the geometry, even the length of the chainstays - is completely customized by size, for performance built just for you.

Features
Guidler
Idler pulley + chainguide = Guidler. Clever, right? Idler eliminates feedback from the high pivot swingarm, keeping your pedal stroke smooth, even when the terrain isn't. The guide, well, it guides.
Suspension Built for You
A rider's center of gravity drives how the suspension performs, yet most bikes use the exact same layout for all sizes. Proportional Response Suspension alters the design by size for truly next-level performance.
Proportional Response Geometry
Long, slack and low – and fully size-specific. As the front of the bike gets longer with each size, the chain stay length increases proportionally, keeping the rider centered between the wheels for true “made for you” handling.
Guardhouse
Downtube protector keeps your frame safe from roost and strikes, while letting water and debris pass through.
The Ai Advantage
Our Ai Offset Drivetrain delivers more tire and mud clearance in the swingarm, and more even spoke angles for a stiffer, stronger rear wheel.
