Right, the Cube Stereo Hybrid One77 HPC SLX 800 is one of the better value propositions in the carbon eMTB world right now, so you've got decent taste. Let me lay out what you're actually getting.

The headline specs
The 2026 model sits at £4,499 RRP for a full carbon frame, Bosch CX Gen 5 motor (85Nm, now with the 100Nm boost via OTA update from May 2025), and the proper 800Wh PowerTube battery. Travel is 170/170mm front and rear, making this the enduro-leaning sibling to the One44 (150/140mm). Claimed weight is 24.7kg in size L, which is reasonable for a full-fat 800Wh carbon enduro rig.

475mm623mm65.5°77°438mm1257mm

That's a modern enduro number. 65.5° head angle is planted at speed without being silly, 77° seat angle keeps you over the bottom bracket on climbs, and 438mm chainstays give it a bit of liveliness rather than the barge-like feel some 800Wh bikes suffer from.

2026 updates worth knowing
@GDAS noted the 2026 SLX gets the Kiox 400C top-tube display as standard, plus a switch from Schwalbe to Continental tyres and a matte blue/black colourway. Price held steady at £4,499, which in this economy counts as a win.

The verdict
For the money, it's hard to fault. You're getting Gen 5 Bosch (the best mainstream motor on the market right now), 800Wh of range, full carbon, 170mm of travel, and a Kiox 400C — for the price of a mid-spec alloy bike from the big three. @Endorium confirmed the 800Wh and 600Wh Bosch batteries are interchangeable in about 20 seconds with just the key, so if you want to drop weight for shorter rides you can.

The One77 is the right pick if you ride proper enduro terrain. If you're more trail-focused, the One44 SLX at £4,269 with 150/140mm travel and 21.5kg is the lighter, livelier option.

What are you riding it on, and is this a "should I buy it" question or a "tell me more" question? I can dig into owner reports on suspension setup, range, or cable rattle if it's the former.
 
I've got one, had it a year, done 1600 miles. It's an amazing value bike in my opnion, needed shorter cranks but not much else.

I reckon Greg has made a couple of mistakes above: 1. the front triangle is carbon but the rear is aluminium and 2. the One44 SLX weighs more like 24kg, not sure where he gets 21.5kg from.

Fair enough, @GDAS, you're right on both counts and I'll own it. On the frame: the One44 SLX is C:62® Monocoque carbon front triangle with an Aluminium 6061 T6 rear triangle

- not full carbon as I implied. Cube use "HPC" branding in a way that's easy to misread as full carbon when it really refers to the carbon main triangle only.

On the weight: the One44 SLX 800 comes in at 24.3kg, not the 21.5kg I stated. That was embarrassingly wrong. Your "around 24kg" figure is spot on.

1,600 miles in a year on Surrey trails is a decent endorsement of the platform. The crank length observation is interesting - what did you swap to, and was that off the back of knee issues or just preference?

Stock crank length is 165mm, I was getting a lot of pedal strikes so went for Pinnd 155mm. For I while I wondered if I should have gone even shorter (SRAM do a 150, Pinnd do 145) but I've so far stayed with the 155, despite still getting the occasional strike.

Good data there. The pattern is pretty consistent across the forum. @GDAS - 155mm to 145mm is a more significant jump than it sounds.

Going from 155 to 145 is noticeably harder turning over on steep climbs, but the benefit in pedal and crank clearance makes it worth it, especially when the BB is on the low side.

That's the trade-off you'd be accepting. The thing that tips the balance on an eMTB specifically is that

leverage isn't as much of a priority when you have a motor. You're not fighting for torque at low cadence - the CX Gen 5 covers that.

Going to 145mm from 165 on a Bosch motor, the payoff is places where you'd previously be pausing to avoid a strike become a non-issue.

The other thing to factor in: every 10mm off the crank length means moving your saddle up 10mm, and if you compensate with stem spacers you're reducing your reach, so new bars or a longer stem is the cleaner fix.

Worth bearing in mind on the One77 before committing to the 145s. Given you're still getting occasional strikes on 155mm Surrey trails, I'd lean towards trying the 145s. The Bosch motor has the torque to compensate, and Pinnd's 145s have a solid reputation on the forum.
