Ride further with less effort.

The Haibike sDuro HardSeven 7.0 is an electric mountain bike that will allow you to explore harder to reach trails with ease. The Haibike Sduro uses powerful Yamaha PW-X drive system that integrates the motor in a compact manner without separate mounting plates that decrease the visual volume of the engine.

The Yamaha PW-X Center mount unit (bottom bracket motor) drive unit is more compact, lighter, stronger: the new Yamaha PW-X definitely has the edge on its predecessor across the board. It has a "triple sensor" system is what holds the product concept of "smooth and powerful" in place. The three sensors are the: 1. a torque sensor that detects pedalling power, 2. a speed sensor that detects the bicycle's speed, and 3. a crank sensor that detects the number of rotations through pedalling. By equipping the three sensors to the unit, the rider is supported by continuous assistance under every riding condition. A more sensitive freewheel and double the number of pawls should lead the cranks to engage much more rapidly and create a more direct and responsive ride as well as greater reliability in this sensitive area of electric bike motors.

The LCD multi function Drive Controller is designed for and has the specs to satisfy all forms of riding.
The newly adopted vertical display makes information such as remaining assist distance highly visible. Attachment is also ergonomically designed, with the display in the centre of the handle bars and switches adjacent to the hands. The display can be controlled without taking your hands off the handle bars, resulting in a safer ride, and smoother control of the switch.

Impact-resistant plastic SkidPlate, similar to a helmet, the SkidPlate protects the motor from damage and is strong enough to absorb even the hardest of strikes that would otherwise damage the motor. Conventional eBike motors sit low in the frame and run the risk of being damaged by strikes to the underside of your bike. In 2012 Haibike introduced the SkidPlate, a simple protective element that effectively protects the motor from below.

The centrepiece of the frame: the motor interface. At this connection point, many important functions come together: the engine mount, swing arm and shock mounts, and the battery and downtube connection. The more stable the interface is, the more stable the entire frame is.
