Frame: We matched double butted tubing precisely to the requirements of the Bosch drive, so as to ensure the best combination of safety and fun. Our Agile Ride Geometry (ARG), tweaked for 2017, and the low positioning of the Bosch drive unit and battery (ODP) both play a key role in achieving this. We gave the WLS frame a short and significantly lower top tube in order to improve manouevrabililty and rider confidence. Details like the IS-mount integrated into the area between seat and chainstays contribute to the clean looks. Available in sizes 14 and 16 inch with 27.5in wheels, and in 17 and 19 inch as a 29er.
Agile Ride Geometry
We ran innumerable tests to develop the Agile Ride Geometry in our series of big wheel bikes. We also added the 27.5in wheel size to the very well received portfolio. Three important details lead to the very agile character. Increased fork offsets let us achieve the same trail as our 26in bikes without having to steepen the head angle, thus maintaining generous toe clearance to the front wheel. Secondly we shortened the chain stays without compromising the seat angle. We invented a patented construction to mount the front derailleur to give us more tyre clearance while keeping a conventional seat angle, leading to a perfect riding position for every rider size. Last but not least we kept the BB height the same as on our 26in bikes. These measures lead to a natural riding position. Every mountain biker will feel immediately at home on a CUBE 29er or 27.5.
