Supporting design

To keep the weight down on this mountain e-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, when centrally mounted it gives excellent weight distribution ensuring you're not hindered when riding. It also maintains that classic mountain bike look.

The 29ER

20" frame and 29" rims gives the S5 greater ability in rough terrain and across bumps or obstacles, especially when it's combined with a Bafang motor producing 45 Nm of torque. For soaking up the bumps, the S5 mountain bike comes equipped with the Suntour XCM HLO DS 29" front shocks, designed for durability and high impacts, these are suited for hard terrain bikes.
