Ride more trails with less effort. The Haibike sDuro HardSeven 4.0 27.5" Electric Mountain Bike - 2018 is a hardtail electric mountain bike that features a powerful Bosch motor to boost you natural pedalling power. With 120mm of front suspension travel to smooth the trail, this is an eMTB that is ideal for trail centre adventures.

Bosch Performance CX Drive Unit:

The Bosch Performance CX has been specially optimized for sporty use. The motor delivers a constant maximum torque of up to 75 Nm up even to a high speed range.

The motor offers an impressive maximum torque of 75 Nm. The “Direct Flow” technique also guarantees powerful support in the lower cadence levels. Trail Control offers a dynamic power management system, that allows the rider to choose the optimum support level (50-300%) for the terrain they are riding, their riding style, and the distance they are looking to cover. “Shift detection” protects your chain by cutting off the torque from the motor during shifting for smooth gear changes.

Bosch Purion Display:

The new compact display is a combination of remote control and display. Positioned on the left of the handlebars, the display provides key information through a small, easy to read display. Its compactness and location make it ideal for extreme ePerformance bikes whose riders seek a display that is reduced to the essentials and well-protected.

All the main functions can be directly controlled: support level (Off, Eco, Tour, eMTB/Sport, Turbo), switching on and off the eBike light, walk-assist, the current speed, the day trip and the total mileage of the bike, and the range, or how far the current charge level of the battery will last in mileage. A backlight in the display makes all information easy to read even in the dark.
