  • Equiped with the Bosch Performance CX which 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 HardSeven comes with agile 27.5" wheels for trips on light terrain. You also have the choice between a high-end lightweight carbon frame or two different drivetrain options in our aluminum bikes.


    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.

    We developed this component especially for the Bosch driven models for a perfect, wear-optimized force transmission from motor to the chain.
    The Haibike Sprocket
    Bosch Performance CX drive has a significantly smaller sprocket compared to classical chainrings and rotates 2.5 times faster than the revolution of the crank. This causes less teeth to transmit more force.

    Custom sprocket

    Many of our models with Bosch drive unit come with a specially developed Haibike sprocket. Each sprocket is milled out of a solid block by a computer-controlled milling machine (CNC). The special shape of the teeth ensures 100% contact to the chain, thus guaranteeing a long life for both the chain and the sprocket. Together with the integrated chainring guide on the sprocket and the chain guard on the pulley wheel, chain jack is nearly impossible.

    The Haibike carbon frames in the unidirectional laminate technique: Especially light, rigid and highly resilient thanks to the parallel alignment of fibres.
    The Haibike UD Carbon Frames
    Being one of the first manufacturers on the ePerformance market, Haibike uses carbon as frame material since 2014. We use our long classic frame manufacturing experience here. Numerous European and World Championships, as well as one silver medal at the Olympic Games, were won on our Haibike carbon models.

    All frame parts made of carbon

    All XDURO and SDURO carbon frames are made of carbon components only (except for the SkidPlate). Every single part is laminated by hand. During this process, the carbon fibre is positioned according to a set plan, parallelly and in accordance with the later stress direction (unidirectional laminate). The advantage is that the tear strength can be used efficiently, very rigid parts can be defined and other parts can be designed with more flex.

    Highly resilient and efficient

    The result is a highly resilient frame which does not only translate every single bit of energy in propulsion, but also reduces the overall weight by its extraordinary low frame weight from 2.790g in a Fully and 1.950g in a Hardtail.

    Small, compact and well protected: the new Bosch Purion. Despite the small size of the remote, the display provides all of the important features and information.
    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.

    Optimized for ePerformance bikes, the Bosch Performance CX motor was developed with a focus on creating a more sport oriented unit.
    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.
