LCD Display

The control center of the SX Series is the LCD C300, with 6 driving assistance modes, speedometer, odometer and battery status along with the ability to measure distance travelled in several configurations.

Seamless Design

To keep the weight down on this e-mountain bike, while at the same time ensuring rigidity and confidence when riding, the bicycle frame is made of lightweight aluminum alloys to which the powerful LG battery has been integrated into the frame. This location is particularly important in mountain bikes, as when centrally mounted it gives excellent weight distribution ensuring you're not hindered when riding. It also maintains that classic mountain bike look due to the battery being inline to the downtube.

Shifting Gears

The SX 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 gradients. 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.

Stopping the Bumps

To stop your SX Series, it comes with front and back Shimano MT200 hydraulic disc brakes, with a 3-finger brake lever. A disc brake with a high, precisely metered braking force in its powerful design. Opposing pistons prevent vibrations. Natural mineral oil as hydraulic fluid, environmentally friendly and is neither toxic nor corrosive. For soaking up the bumps, the SX Series e-mountain bikes come equipped with the Suntour XCM HLO DS front shocks, designed to take big impacts, well suited for hard terrain bikes.
