You know you're on a great trail bike when it just gets out of the way and lets you enjoy the ride. It's the reason that, for the Stereo Hybrid ONE44 HPC SLX 800, we began with a 150mm Fox 36 Float Rhythm fork and matching Float Performance shock. Combined with a Newmen Performance 30 wheelset and Continental Kryptotal 2.4in tyres, it's the closest we can get to a magic carpet ride. Bosch's CX motor and an 800Wh battery deliver up to 120Nm of torque to the trail via Shimano's slick-shifting, legendarily reliable XT 1x12 gears, while the Kiox 400C display shows you what's going on. And strong, progressive Shimano XT 4-piston hydraulic disc brakes with 203mm rotors bring you safely to a stop, on demand. With a remote dropper post included in the mix, you simply need to add your spirit of adventure... and ride.Frame descriptionA great bike is all about the detail, and the Stereo Hybrid ONE44 HPC's frame is chock-full of clever details. You'll notice the Internal Cable Routing because it so neatly complements the High Performance Carbon main triangle's clean lines, while the angle-adjustable headset means you can tailor the handling to your specific requirements. A Direct Mount chain guard keeps the gears on the straight and narrow, and the neatly integrated Bosch top tube controller plus Purion 400 display show you what's going on with the powerful Bosch CX drive and 800Wh PowerTube battery at a glance. With a 150mm fork and 140mm of rear-wheel travel, it's ready to take on the toughest of trails. The UDH dropout means it's future-proof, too. And, with Size Split, there's a wide range of sizes to suit most riders.
Mountain biking just got even more exciting. Our Stereo Hybrid ONE77 HPC SLT 800 is the reason. This powerhouse combines a lightweight carbon frame with progressive mullet geometry, an adjustable head tube angle, a capable four-bar suspension system (FSP 4-Link), and of course, the now even quieter Bosch CX drive unit with a massive 800 Wh battery. And that’s not all. How about Sram’s wireless AXS XX Eagle Transmission? Or the carbon Newmen Phase 30 wheels, complete with a set of super-solid, grip-laden Schwalbe tires? We’ve outfitted the 29 inch front wheel with a Schwalbe Magic Mary and the 27.5 inch rear wheel with a Tacky Chan, both 2.4 inches wide. The whole setup is screaming for speed, speed, and more speed. Thankfully, reliable stoppers are on board: Magura Gustav Pro brakes. The suspension components are from Fox’s Factory series; a 36 Grip X2 fork in front and a Float X2 Factory shock in the rear. Let those mountains come – you’re ready for them.A significant performance boost for compatible CUBE bikes fitted with selected BDU38 Performance Line motors will be available from 4 May 2026. The upgrade is available simply by using the Bosch eBike Flow App. No other action is needed.After downloading Performance Update 2.0 via the eBike Flow app, you can now choose to increase these peak values up to 120Nm torque , 600% support and 750 watts, with peak power also available for longer periods depending on riding conditions.Maximum rider support of up to 600% is limited to speeds between 0 and 15km/h (this doesn't affect the speed limit of 25km/h for pedal assistance, which remains the same). Some trekking and city bikes equipped with hub gears may have lower performance increases to remain within manufacturer recommendations.More boost. More precise control. Performance, redefined.
Challenging trails need a suspension set-up to match, which is why we gave the Stereo Hybrid ONE77 HPC SLX a Fox Float 38 Rhythm fork and Float X Performance shock. Together, they deliver 170mm of rock-swallowing travel front and rear, with loads of adjustment so you can get it dialled. The Bosch CX drive and 800Wh PowerTube battery give your pedalling an unobtrusive but very effective boost, via Shimano's legendary XT 1x12 gears – and the top tube-mounted Kiox 400C display shows you exactly what's going on. Meanwhile, the mullet Newmen Performance 30 wheelset – shod with Continental Argotal and Kryptotal 2.4in tyres – is held in check by Shimano's new XT hydraulic disc brakes. Add it all up and, with a remote dropper seatpost, too, it's the perfect formula for big mountain fun.Frame descriptionThe Stereo Hybrid ONE77 HPC frame – with 170mm travel front and rear and a mullet wheel setup with 29in front and 27.5in rear – is all you need for big days out on big mountain trails. But, as with all CUBE designs, the devil is in the detail. So, for example, we added Integrated Cable Routing for super-clean looks, and then threw in an angle-adjustable headset so that you can tweak the handling to your taste. The 800Wh PowerTube battery sits unobtrusively in the carbon down tube, just above the Bosch CX drive. A UDH dropout on the aluminium rear triangle is tough and future-proof, and we also added a Direct Mount chain guide to keep you driving forwards even when the going gets rough.
