Large-sized drive in the new D-Series from BionX

BionX has already cooperated closely with Wheeler for the "Evo 2.0" bike, and now comes the next prank: BionX has implemented functions in the D-Series motors that are intended to position the drive as an expert for off-road use. Wheeler is also presenting a Falcon full-suspension bike that relies on the new D-Series drive.

The most striking feature of the new drive is the very slim design of the motor housing. And that the spokes are not attached to the flanges of the motor housing hub, but are pulled far into the center of the wheel. The BionX engineers have the following arguments for this design: "By increasing the motor diameter, the magnetic components move at a higher tangential or circumferential speed. By increasing the motor diameter, less electrical power is required to generate torque. This enables us to build a lighter motor. This design makes a significant contribution to the 250% higher continuous output." As the motor housing on the rear wheel is not subject to dynamic loads, it is possible to use extra-light motor housings with an exceptionally narrow profile. The rear wheel therefore weighs just 3.9 kg.

The spokes of the D-Series motor are positioned close to the center of the wheel and BionX lists the advantages of the special spoking method: The result is a more dynamic wheel with more flex in the vertical direction. This offers the sporty rider more comfort, more grip and more traction on the trail. The drive offers a maximum torque of 50Nm and a nominal torque of 25Nm.

Wheeler is launching the E-Falcon, E-Eagle, E-Protron and E-Passera models for the 2014 season. Here is the E-Falcon with 100 millimeters of travel and 29er wheels.

The new D-Series motor celebrated its premiere at Eurobike 2013. For the 2014 model year, a number of OEM bikes "powered by BionX" will be equipped with the new motor - starting with Wheeler, the official launch partner.
