The HardSeven 4.0 comes with agile 27.5-inch wheels and a 120mm suspension fork for trips on light terrain. The powerful Bosch Performance CX motor paired with a responsive aluminum frame creates a lively ride, while a SRAM 11-speed drivetrain and Tektro hydraulic disc brakes ensure you have the gearing and braking power to get up and down steep hills with confidence. You can keep track of your ride metrics via the easy-to-read handlebar-mounted LED display so you always know when it's time to make your way back to the trailhead, and the selectable assistance levels let you dial-in your preferred amount of power for an enjoyable experience everywhere you ride.

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 Integrated Motor Concept
Haibike technically and visually perfected the integration of the motor into the frame.
The motor is the technological core and defining characteristic of an eBike. Thanks to our Gravity Casting motor interfaces we 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 SkidPlate is a useful protective device from a technical perspective, but also allows us to optically integrate the motor to make it part of the frame. Unlike other integration concepts, the motor looks like a natural part of the eBike.
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.
