BUT LESS WEIGHT: Shimano's EP8 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.
