Cube has been at the forefront of the e-mtb movement for some years and had a serious proposition in earlier version of the Cube Stereo Hybrid a few years ago.

Cube has certainly worked the numbers well on this flagship bike with four sizes, and is loaded with purposeful and high end components. At 160mm travel front and rear we feel this is where the e-mtb is best placed to have the most fun uphill as well as downhill. This is an evolved beast and as such hits a spot in the 2017 Dirt 100, the first year that we’ve included a selection of e-bikes.

Cube boldly say that this bike is at the forefront of “performance enduro riding” and they’ve certainly sweated the details when it comes to the frame layout and geometry. The Stereo Hybrid has a chainstay length a touch shorter than many e-bikes but most notable is the bottom bracket height, which is in a great position to aid the cornering character. They’ve kicked the head angle back to a shade over 66 degrees; up to date and ready for action. But what about the suspension hardware?

This is the first time a shock with a piggyback reservoir has been fitted into the Cube Hybrid frame set and it’s likely that it’ll need it. The hammering that the bike is likely to endure given its attacking geometry means no holding back. The unstoppable Fox 36 Factory takes care of matters up front with a Float X with Evol chamber and Kashima coating out back. We were interested to see how the standard width fork shapes up to other Boost built e-mtb’s and the performance of the rear damper. It’s true we do prefer the Boost sizing on forks but the 36 was nevertheless hard to fault with its supportive damping and control. The rear damper was not a match for the fork, something we have experienced with Cube bikes in the past and it really needs a more substantial tune here. An improvement on the 2017 model?

‘The Cube can be worked hard into tough terrain, the bike driving confidence up with every turn’

Rolling on a 148x12mm Boost rear wheel, Super Gravity Hans Dampf tyres from Schwalbe, the Cube uses a DT CSW EM wheelset with 28 spokes which raised an eyebrow or two, weighing in at the lighter end of the scale. We’re real fans of the Magura MT7 brakes and the bike comes with a 200/180mm disc set up. Gearing is 15T up front with 11-42T at the rear. Overall it’s all about lightweight, fast speed.

The super grippy Schwalbe tyres offer an instant advantage over the weak rubber fitted to some e-mtb’s. The Cube can be worked hard into tough terrain, the bike driving confidence up with every turn. You soon recognise that the weight and grip combination gives bucket loads of traction and support. The geometry makes for excellent handling and steering characteristics too.

A cluttered cockpit of cables and displays needs tidying, the Bosch Purion system would be better and is now standard on the 2017 version of this bike, along with SRAM EX1 gearing as seen on the Trek Powerfly LT. Cube have upgraded the bar to an 800mm wide model from RaceFace too. Wise moves on all fronts.


  • Price: £4199 (2016) // £4999 (2017)

Cube has put together a great package with the latest version of the Stereo Hybrid. The wheelset, tyres and brakes in particular are of note and are areas that are often looked on many e-bikes, even on the higher priced models. With a few tweaks the damper tune this bike could be near the top of our e-mtb rankings as the travel on offer and geometry here make for a great all-action bike.
