The HardSeven Carbon 8.0 features a high-modulus carbon frame and comes with agile 27.5-inch wheels and a 120mm suspension fork for fast trips on light terrain. The powerful Bosch Performance CX motor paired with a SRAM 11-speed drivetrain and Tektro hydraulic disc brakes ensure you can pedal up and down steep hills with confidence, and a handlebar-mounted display lets you monitor ride metrics so you always know when it's time to make your way back to the trailhead. Selectable assistance levels let you dial-in your preferred amount of power for an enjoyable experience everywhere you ride.

Haibike SkidPlate

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

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 2012, 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. 

Plastic as ideal raw material

This is why we also use a special, shock-resistant plastic. This material conducts the incoming forces very well but stays dimensionally stable even under severe deformation at the same time compared to other materials which do not switch back to their original shape after deformation. The production in the corresponding color perfectly hide scratches and smaller damage. If required, the SkidPlate can simply and cheaply be exchanged.



Haibike Step-In Battery Concept

Technically precise and visually compelling: the unique integration of the Bosch battery, developed exclusively by Haibike.

Integrating batteries into frames in both an elegant and technically feasible manner is one of the biggest challenges in the design and engineering of eBikes. Our Step-In Battery Concept proves it is possible.

Visually and technically convincing

To reduce the visual "weight, " we sink the Bosch battery slightly into the downtube. Thanks to the combination of hydroformed tubes and special castings we can dispense with welds and thus eliminate inaccurate attachment points. This technique also reduces the distance between the motor and battery by 11mm.



Haibike Full Carbon Interface

The Full Carbon concept allows us to elegantly mount the Bosch motor without adapters or holder plates which increases the weight, size and tolerance of the frame.

Normally the Bosch motor is mounted via adapters or holder plates to the carbon frame, which increases the weight, the size and increases tolerances. For this reason, we developed the Full Carbon Concept that elegantly solves all three problems.

The motor is directly screwed to the carbon frame, without using additional adapters. We consciously avoided metal cores in the interface and designed a carbon interface. The result is a mount that optimally transmits force into the frame, reducing the weight and the space required, while increasing both stability and precision


Haibike UD-Carbon Frame

The XDURO carbon frame is created via a unidirectional laminate method, making the frame light, stiff and tough, thanks to a parallel alignment of the fibers.

As one of the first manufacturers in the ePerformance market using carbon as a frame material, we benefit from our years of experience making performance bike frames. While riding Haibike carbon bikes, athletes have conquered numerous European and World Championship titles, including an Olympic silver medal.

All frame parts made of carbon

On XDURO carbon frames every frame component (except for the SkidPlate) is made out of carbon. Each piece is handmade so the carbon fibers are aligned parallel via a specified plan that follows the subsequent stress directions (unidirectional laminate). This concept allows us to exploit the tensile strength of the carbon fibers to create areas with particularly high stiffness and others with more flex.

Durable and efficient

The result is a heavy-duty frame that converts every ounce of energy into propulsion. The low frame weights significantly reduce the total weight of the bikes.


Bosch Performance CX Drive Unit

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

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.

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.
