Each Haibike SDuro HardSeven 4.0 has a 27.5-inch wheel diameter that is more stable and sure-footed, while offering very low rolling resistance, especially at high speeds. The larger diameter wheels enable this E-MTB to sail over bumps and holes to give a smooth ride and all day long comfort, while also allowing the rider to push hard over technical terrain. A perfect ebike for those looking to start taking their riding off road, while still having the versatility to offer comfort and speed on paved trails.
