Frame: The double butted aluminium Superlite frame was developed specifically to match the requirements of the new Bosch system, and we've upgraded it for 2017 to include clean-looking, low-maintenance internal cable routing. The frame is extremely stiff despite being very light - and that means fantastic drivetrain efficiency and superb steering precision. That's a good start, but it's really the combination of our in-house Agile Ride Geometry (ARG) and the optimal positioning of the Bosch system (ODP) that transforms the Reaction Hybrid Race into a fleet-footed, fast-accelerating trail rocket with the kind of handling that most e-bikes can only dream of.
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.
