This is a 2017 model size MEDIUM 29er hard tail. 

Nothing embodies the enjoyment and the fun of biking as perfect as a CUBE e-mountain bike. And hardly an E-MTB can accommodate the equipment and performance of the CUBE Reaction SL. In the framework newly developed for 2017, our engineers put their entire knowledge and demonstrate in an impressive manner what is possible in high-end aluminum frame construction. A bike that will make you smile, kilometers by kilometer.


Our E-MTBs are already among the best. Nevertheless, we do not rest on this success, but try to go a step further each year. Thanks to the completely new design for 2017, with a clear focus on the best possible integration of Bosch drive technology into the frame, we achieved an even cleaner and sporty look, improved handling and last but not least increased efficiency. Our Agile Ride geometry (ARG) makes the Reaction Hybrid SL the reference in handling on e-mountain bikes. Its low center of gravity and the perfect combination of agile steering and traction stability guarantee an unmatched driving pleasure. The internal cable guide protects the cable against damage and allows an easy and comfortable switching process.
