New Cube Reaction Hybrid SLX 800 2026
Reaction – Urban and off road capable

The Cube Reaction Hybrid 2026 combines the efficiency of a hardtail with the seamless support of Bosch’s Performance CX drive unit, making it a highly capable electric mountain bike for trail riding, commuting, or weekend adventures. The 800Wh PowerTube battery is neatly integrated into the frame, giving the bike clean lines and long-range performance.
Attention to detail is everywhere: an integrated seat clamp and internal cable routing enhance the sleek design, while a pre-installed chain guide adds reliability on rougher terrain. The frame is ready to accept ACID mudguards and a luggage carrier, and with X-Connect, adding a compatible ACID front light is as simple as plugging it into the headset.
For riders who want to go even further, the Reaction Hybrid is PowerMore-ready, allowing the addition of an optional 250Wh range extender. And thanks to Cube’s Size Split system, there’s a perfectly proportioned frame for almost every rider.

Bosch Purion 200 display
Control unit with compact colour display and fully networked in the smart system: that’s the Purion 200. The all-in-one solution ensures an uncluttered handlebar, is in close proximity to the thumb and offers a razor-sharp display of ride data as well as simple, ergonomic control of all eBike functions. Combine the Purion 200 with an additional display – for even greater convenience.

Big travel. Bosch power. Trail ready.

Reaction Hybrid SLX 800 – in depth
When you’re exploring new places, the last thing you want is to be worrying about your bike. That’s why the Reaction Hybrid SLX is equipped with Shimano’s XT 12-speed gears and matching XT 4-piston hydraulic disc brakes. Together, they offer easy use and exceptional reliability, so you can just concentrate on the ride. It’s the same story with the Fox 34 Float AWL suspension fork, which combines smooth bump-swallowing comfort with excellent steering precision. The Bosch CX drive and 800Wh PowerTube battery speak for themselves, offering quiet and unobtrusive pedal assistance for miles of smiles. The Newmen Performance 30 wheelset is shod with 2.6in Schwalbe Smart Sam tyres for excellent grip and ride comfort. And we even fitted a remote dropper post, for increased confidence on tricky trails. Where’s your next adventure?
