This location is particularly important in mountain bikes, when centrally mounted it gives excellent weight distribution ensuring you're not hindered when riding. It also maintains that classic mountain bike look.


The S Series is equipped with front and rear Shimano Alivio derailleurs, which when used together not only feel like a traditional pedal bike, but offer a multitude of gear options for different terrains and gradiants. Those gears are accompanied by a brushless and non-resisting electric motor to instantly transform this into an E-Bike you will keep going back to.

Natural mineral oil as hydraulic fluid, environmentally friendly and is neither toxic nor corrosive. For soaking up the bumps, the S Series mountain bikes come equipped with the Suntour XCM30 front shocks, designed to take big impacts, these are suited for hard terrain bikes.
