The Cube Stereo Hybrid 160 HPC SL 625 27.5 Electric Mountain Bike is smaller and more agile than its larger-framed stablemates, the Stereo Hybrid 160 HPC 625's frame is designed to punch above its weight. With the 625Wh battery and fourth-generation Bosch drive unit housed entirely inside the down tube, it's as powerful as it is good to look at. Hidden by a cover with shock protection, push-button access and a hidden lock, the battery is both secure and easy to access. The trunnion shock mount, oversize linkage bearings, Boost 148 rear end and 1.5in head tube all contribute to accurate tracking, even when it's all coming at you thick and fast. And sorted, race-inspired geometry gives you the advantage you need to show the trail exactly who's boss.
