XDURO Dwnhll 9.0 2019 - Bosch Electric Bike

TheHaibikeDwnhll models combine the ability to shred thedownhills as well as any gravity bike, with the capability to master steep, technical, uphill climbs. The limits of what was previously possible on aneMTB have been thrown wide open. 

EspeciallyeMTBs often suffer from impacts or stone chipping which damage the low-situated motorseverly. Therefore, we were the first manufacturer to introduce theSkidPlate back in 2012, a protection element which protects the bottom side of the motor. 

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 motors pose two challenges for engineers at once when developing an efficient chassis: its construction size and its relatively small sprocket. Usually, the chainstay bearing has to be installed close to the point of contact between chain and sprocket. Due to the small size, this would result in the bearing running directly through the motor which is, of course, impossible. Therefore, we created a simple but efficient concept: the Haibike Sprocket Equalizing System (S.E.S).
