As a true all-mountain bike, JEFFSY delivers convincing performance for everything from after-work rides and blasting your favorite single track to epic alpine crossings. Our versatile all-rounder is both an efficient climber and a playful companion for technical descending, high speeds and fun jumps. And JEFFSY features a bottle mount. So if you only have room for one bike in your garage, and that bike has to do it all, JEFFSY is your weapon of choice!
The JEFFSY is a versatile all-rounder with impressive climbing capabilities and the gravity DNA that all YT bikes share. Thanks to our award-winning V4L suspension technology, it is very sensitive off the top, with good mid-stroke support and plenty of end-stroke progressivity.
This gives the JEFFSY plenty of pop and agility in both the 27.5-inch and 29-inch versions. The JEFFSY wants you to pull up off every little lip, but it also has enough in reserve to give you a feeling of safety in rough terrain and on big jumps. And on the climbs, the ergonomic seated position and the high anti-squat give JEFFSY plenty of drive.
