Our E-Mountainbike hardtail frames were already highly regarded, but that wasn't good enough for the CUBE design team. The Reaction Hybrid SLT sets a new benchmark in E-Mountainbike design thanks to its sophisticated, gravity cast down tube and bottom bracket design. Completely enclosing the battery under a water-resistant cover, it's more than just an aesthetic upgrade. The lower centre of gravity, combined with our proprietary Agile Ride Geometry, results in even better handling than before. It also frees up enough space inside the frame for two water bottle mounts – and you can charge the battery without removing it, too. In keeping with the frame's elegant looks, we ran cables internally to reduce clutter and the need for maintenance, and the Boost 12mm thru-axle at the rear helps with power transfer and steering accuracy.
