Cube Stereo Hybrid 140 HPA SL 500 27.5 2017 Electric bike

The Stereo Hybrid HPA 140 SL is the undisputed top dog of All-Mountain e-bikes. Given the innovative energy that we've ploughed into designing this bike, it's fair to call it one of the most advanced Hybrid full suspension bikes of all time. The features exclusive to the SL version will make you the envy of everyone. And once you've experienced the performance and subtly unfolding power of the new Bosch CX drive, you'll want to ride it hard along all your favourite trails - and seek out and explore new singletrack - time and time again.

The 7005 High Performance Aluminium (HPA) frame is based around our much-admired Agile Trail Geometry (ATG) and Efficient Trail Control (ETC) suspension design. Using Tuned Drive Position meant that we were able to optimise chainstay length, making for surprisingly lively handling on the trail. And, since that means you'll probably be riding faster than ever, we specced wider 148mm Boost hubs to improve stiffness and reliablity. Gear cables run internally - hidden away, tidied up and protected from damage. Another highlight is the CUBE Performance Cover, designed especially for All-Mountain use. Integrated impact protection absorbs the initial energy on making contact with the ground, while the shock absorber takes on and neutralises the rest. The drive unit and frame are optimally protected against impacts - and the included chain guide keeps the chain away from the chainstay on even the roughest trails.

We selected components to perform one function: provide 100% All-Mountain performance. Incredibly responsive suspension performance and massive reserves for tackling the roughest terrain come courtesy of a brace of Fox's suspension components: a Float 34 fork up front and Float DPS EVOL shock at the rear. Even in appalling weather, Shimano's hydraulic XT brakes with 180mm rotors will stop you reliably and quickly. And, for 2017, we just had to select SRAM's XO1 Eagle 12-speed drivetrain. With a massive gear range driven through a 10-50 tooth cassette, it's the ultimate e-bike transmission. Working in combination with Bosch's most powerful CX Drive Unit, 75Nm torque and makes this bike a formidable weapon with which to tackle even the steepest of mountain climbs. Grippy Schwalbe Hans Dampf tyres - in Super Gravity trim at the rear - with a RockShox Reverb Stealth dropper post, Race Face cockpit and 760mm wide bars all make light work of technical singletrack.
