Details
On long jaunts over country trails, nothing beats the comfort and efficiency of Haibike's SDURO HardNine e-bike. This 29er rolls fast and smooth thanks to a 100mm suspension fork and wide all-terrain Schwalbe tires, while the 9-speed Shimano drivetrain paired to Yamaha's powerful 500-watt electric motor provides the assistance you need to conquer long rides. Hydraulic disc brakes give you control on steep descents and maintain power even in wet weather, and a smart mix of cockpit components ensure a great fit. And, to make sure you don't overextend your journey, a handlebar-mounted LED display provides important information and selectable functions within easy reach.
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.
The centerpiece 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.
The motor is the technological core and defining characteristic of an eBike. Thanks to Haibike's Gravity Casting motor interfaces, they can integrate the motor in a compact manner without separate mounting plates. This concept reduces the space required to mount the motor and decreases the visual volume of the engine.
The Yamaha PW unit is proven to be a powerful and reliable motor. Thanks to its Zero-Cadence system, it supports the rider from the first revolution of the crank. As one of the few motors available allowing a dual chainring, the Yamaha system is able to offer a broad range of gears providing more gear options out on the trails. Given its high maximum torque of up to 80Nm, its compact size, and its low noise, the Yamaha PW is one of the best eBike systems for sporty use.
The Yamaha LED display is a compact yet robust display and remote unit. Despite its small size, it provides the rider with all essential information. Positioned on the left of the handlebars, the remote is easily accessible. Information available includes: the selection and display of the support levels (Off, Eco+, Eco, Standard, High), the current speed, the battery charge level, and the remaining range. The display also allows you to switch on and off of the main light.
