The Cube Stereo Hybrid ONE77 HPC SLX 800 is built for riders who demand more from their e-MTB – more travel, more control, and more capability in big mountain terrain. The C:62 carbon main frame is paired with an aluminium rear triangle, delivering 170mm of suspension travel at both ends via Cube’s Efficient Trail Control four-bar system. Agile Trail Geometry ensures stability on steep descents without losing agility in technical sections, while the angle-adjustable headset lets riders fine-tune handling to their style.

At the heart of the bike is Bosch’s Performance Line CX motor, delivering up to 120Nm of torque for powerful, natural-feeling assistance on demanding climbs. The fully integrated 800Wh PowerTube battery provides the range for long days in the mountains, with the Bosch Kiox 400C display offering clear ride data and intuitive control through a top tube-mounted controller.

Suspension duties are handled by a Fox 38 Float Rhythm GRIP fork and a Fox Float X Performance shock, both air-sprung and easily adjustable to rider preference. Shimano’s proven XT drivetrain provides precise, reliable shifting across a wide 10-51T cassette, while powerful XT BR-M8220 4-piston hydraulic disc brakes with 203mm rotors deliver confident stopping power on steep, technical descents.

The mullet wheel setup – a 29” front wheel for rollover ability and a 27.5” rear wheel for agile handling – uses Newmen Performance 30 tubeless-ready rims, wrapped in Continental Argotal (front) and Kryptotal (rear) 2.4” tyres for grip and stability on rough trails. A dropper seatpost, ACID finishing kit, and trail-focused cockpit complete the build, ensuring comfort and control wherever you ride.

The Stereo Hybrid ONE77 HPC SLX 800 is a true big mountain e-MTB – long-travel suspension, Bosch power and practical features combine to make it ready for enduro lines, steep descents and epic all-day rides.

Bosch Performance Update 2.0

Bosch have dropped a fresh update for the Performance Line CX and CX-R motors, and it’s a big one for riders who want more punch on the trails. The update is available for the latest generation motors with the codes BDU384Y and BDU386Y, and it can be installed straight from the Bosch eBike Flow app. Nice and easy.

Once you’ve downloaded Performance Update 2.0, you can crank the motor up to a huge 120 Nm of torque, with up to 600% support and 750 watts of peak power. Bosch have also tweaked things so the motor can hold that power for longer when the riding conditions allow.

The 600% support figure only kicks in between 0 and 15 km/h, so it’s all about helping you power up steep climbs and tricky sections. The maximum assisted speed stays the same at 25 km/h.

As with previous Bosch updates, you can still customise the motor settings in the app to suit your riding style. Whether you want maximum power for steep tech climbs or a more natural feel on longer rides, you can dial it in how you like it.

Performance Update 2.0 is available for all CX Gen 5 and CX-R Gen 5 motors. It also brings Extended Boost (Bosch Overrun) and support for the new drivetrain tensioner system, which helps reduce lag when you get back on the pedals. Bosch are also adding more features and connectivity options, including Garmin integration and new power supply options.

One thing worth keeping in mind — more power means more stress on drivetrain components, so increased wear is expected over time. If you’re unsure about compatibility, servicing or upgrading components, get in touch with us and we’ll be happy to help.
