More dynamic and range, but less weight
Shimano's EP801 e-drive offers dynamic power and a lightweight system that supports the JAM² 7.9's agile geometry. You have two motor support profiles that you can customise to your needs. Thus, you can easily switch via the display between a smooth and continues profile for your ride to the trails and a very dynamic, progressive profile for your actual trail ride. It's all up to your preferences. Furthermore, our specially developed, integrated, yet removable battery supports your super long rides with 720 Wh. Additionally, a USB-C port on the top tube gives you the opportunity to charge your devices.

Optimised kinematics for strong progression
With the F.O.L.D. kinematics of our JAM² 7. series, you are ready to shred even more. It combines the well-liked sensitivity of our F.O.L.D. with a strong bottom-out resistance. The characteristics are completely progressive which results in a chassis that offers a lot of stability in rough terrain. Especially e-mountain bikes with their additional weight of motor and battery benefit from more progression. This allows you to handle any trail while the chassis still provides comfort for long laps. Furthermore, the lower standover of the JAM² 7.9 gives you more space to play on the trail.

More fun on the trails
Riding performance first. The JAM² 7.9 will make your ride better – every time. An agile, nimble geometry in a slim, compact design will push you over all kind of trails whether technical or flow. The FLIP CHIP at your JAM² 7.9's linkage can be used to adjust your geometry to an even more aggressive riding style. The small adjustment of the head angle from 65,5° to 65° changes your whole set-up goal making it even more downhill-oriented. Additionally, the specially developed C.I.S. (Cockpit Integration Solution) design ensures a clean cockpit and constantly seamless shifting and braking. On top, all your essentials fit in the tool bag between top and down tube (except size S).
