Details

The SDURO Hardtails are the optimal choice for those looking for an eMTB for easy terrain or tours. The wide variety of bikes and the attractive price-performance ratio make this series one of the most successful worldwide.

Technology

    Made of shock-resistant plastic, the light component protects effectively from scratches or motor damage.
    The Haibike SkidPlate

    Especially eMTBs often suffer from impacts or stone chipping which damage the low-situated motor severely. Therefore, we were the first manufacturer to introduce the SkidPlate back in 2013, a protection element which protects the bottom side of the motor.

    Bottom side protection

    Here the concept of a 'sacrifice part' applies: Similar to a helmet, the SkidPlate absorbs impact forces by deformation or destruction which would otherwise damage the significantly more expensive motor.

    The heart of the Haibike alu frame: light, highly robust and complex manufacturing with a special casting technique known from the motorcycle industry.
    The Haibike Gravity Casting Interface

    It is the heart of the frame: the motor interface. Here, many crucial functions such as motor mount, rocker and damper mount, as well as the interlocking battery and lower connection. A robust frame is based on a sturdy interface.

    Casting technique known from the motorcycle industry

    Therefore, since 2010, we use a casting technique which is known from the motorcycle industry, the so-called Gravity-Casting technique. In this process, negative forms made of compressed sand are placed in big forms. These sand forms are then filled with an alloy of alu and zinc and afterwards rotate in precisely calculated axes. Due to gravity, the alloy spreads evenly and results in an even casting thickness.



    Light, robust and precise

    Thanks to this procedure, extremely robust components can be produced which are then exposed to an extensive X-ray control in order to achieve the casting seal of approval. A subsequent, computer-controlled postprocessing ensures stable precision.

    Small, robust and displays important information and functions.
    Yamaha LED Display
    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.

    Powerful, reliable and proven: The PW engine from eBike drive pioneer Yamaha provides dynamic support up to 20mph and allows a dual chainring.
    Yamaha PW Drive Unit
    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 70Nm, its compact size, and its low noise, the Yamaha PW is one of the best eBike systems for sporty use.
