Product Description


The Haibike SkidPlate

Especially eMTBs often suffer from impacts or stone chipping which damage the low-situated motor severly. 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 colour perfectly hide scratches and smaller damage. If required, the SkidPlate can simply and cheaply be exchanged.

The Haibike IntegratedMotor concept

The motor is the technological heart and optically the basic feature of an eBike. Thanks to the GravityCasting Interface, we are able to slightly remodel the motor and as a result, get rid of the mounting plates. Thus, we reduce the construction space to a minimum and the optical volume to a fraction of its original size.

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.

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.
