Cube Reaction Hybrid SLX 2025 - ADVENTURE ON!

The Cube Reaction Hybrid SLX 2025 is a performance-driven e-MTB built to conquer any trail. Its seamless integration of Bosch's powerful e-system delivers powerful capable performance, while features like PowerMore compatibility and integrated cable routing enhance both capability and aesthetics. If you're ready to push your limits and explore new horizons, the Reaction Hybrid SLX is your key to unlocking unforgettable off-road adventures.

Cube Reaction Hybrid SLX 2025 - Sage Green/Prism

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 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 AWL Float suspension fork, which combines smooth bump-swallowing comfort with excellent steering precision. The Bosch CX drive and 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?

Fully Intergrated Battery 

 

The Fully Integrated Battery system tucks the power of Bosch's battery out of sight, safely inside the confines of your bike's downtube. Hidden beneath a splash and dust-proof cover and secured with a lock to prevent theft, it allows the frames to be brilliantly functional as they are good to look at.

 

Modular Battery System

 

In many ways the battery is the heart of an e-bike. That's why, with our Modular Battery System, we've made a setup that's easy to use. You can charge the battery on or off the bike, and we've made room for even high capacity batteries. You'll wonder how you ever managed without it.

Advanced Internal Cable Routing

 

Gear and brake cables need a way to get from handlebar controls to frame – but what if there was no need for holes near the head tube? We came up with a design that takes cables into the frame via the headset, maintaining full internal cable routing but making it even neater and less obtrusive.

Aluminium Superlite

 

CUBE's Aluminium Superlite starts with heat-treated 6061 aluminium, which has the qualities – high fatigue resistance, good stiffness, low weight and excellent strength – that are important for a bicycle frame. Then we make it into double butted tubes, to reduce weight without sacrificing any of its strength. The result? Exceptionally light, strong and tough frames.
