2025 Cube Reaction Hybrid Pro 800 - Step Thru Electric Mountain Bike - Smaragd Grey / Prism

Season:2025

Brand:Cube

Code:808252

With its 800 Wh battery, powerful Bosch motor and elegant CUBE design, the Reaction Hybrid Pro 800 blends mountain bike ruggedness with hybrid ease of use. The result? It's a bike that can go pretty much anywhere, from city streets to mountain trails and everywhere in between.

We specialise in really neat frame design, and the Reaction Hybrid is no exception. With the 800 Wh PowerTube battery neatly concealed and the Bosch CX drive housed securely, its svelte lines disguise lots of clever features. It's PowerMore-ready, making it easy to add up to 250 Wh of extra battery capacity. The integrated seat clamp and cable routing complement the clean aesthetic, whilst a UDH gear hanger makes it as future-proof as possible.

There's a built-in chainguide mount too, and it's also ready to accept ACID mudguards. And, with Size Split, it's easy to find the perfect fit for every rider. We've thought of everything, so you can just ride.

Professional Opinion
  • Fully Integrated 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 us to design beautiful e-bike frames that are as brilliantly functional as they are good to look at.
  • Accessories
    Accessories like a kickstand, fenders and luggage carrier can really extend the versatility of your CUBE bike. We designed mounting points that integrate so neatly with each frame, you'll barely notice they're there – but they also provide a simple, strong and secure attachment for any future upgrades.
  • 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.
  • Integrated Seatpost Clamp
    Our Integrated Seatpost Clamp is all part of our quest to sweat the details, so that you can reap the rewards. Its minimalist design suits the frame's pared-back aesthetic. And, of course, that's important – because why wouldn't you want your bike to look great? But it also saves a few grammes too. And that matters just as much...
  • 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.
  • SizeSplit
    The right bike should fit you perfectly. That's why we created SizeSplit. For shorter riders, the smaller 27.5in wheel standard allows us to build frames that fit well while remaining agile and sure-footed. And, for taller riders, we built a range of sizes around the fast-rolling 29er wheel standard. Whichever one you choose, you can be sure of a fit that makes your bike feel as though it was built just for you.
  • Boost148
    A wider hub makes a stiffer wheel, and a stiffer wheel means better handling. That's the thinking behind the Boost 148 rear hub standard, which allows wider flange spacing for better wheel performance without impacting on shifting accuracy or drivetrain efficiency. Simply put, you can go faster and harder with better handling and stronger wheels.
  • Additional Mounting Points
    There are times when it's really useful to have a lock or a multi-tool with you, but what if you don't have a suitable bag? The Reaction Hybrid Performance frame has you covered, with dedicated mounting points below the top tube specifically designed to accommodate a compatible lock or tool. Convenient, rattle-free and always to hand...
  • Agile Ride Geometry
    For off-road riding you need a bike that responds quickly, but also feels stable and secure. That's where Agile Ride Geometry comes in. Offering an ideal blend of on-demand steering precision, climbing agility and descending stability, it's perfect for every rider who values their time on the trail. If you're a mountain biker, you'll instantly feel at home...
  • Universal Derailleur Hanger
    One standard for all: gear hanger replacement made easy thanks to the innovative Universal Derailleur Hanger. With a design that includes some room for pivoting to help prevent chain jams, it improves shifting performance and works with all drivetrains. Best of all, it's a standard part that is available anywhere.
  • Gravity Casting
    Gravity Casting moulds liquid aluminium into highly complex frame sections, resulting in extremely strong structures that can better withstand stress. For example, with our Hybrid models we're able to produce a motor mount that's optimised to cope with the loads placed on it in this specialised application, without adding unnecessary weight or sacrificing strength.
  • 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.
  • Frame Organics
    A bicycle frame is an amazing piece of engineering. And now, with our Smooth Welding technology, we're able to give it the elegant appearance it thoroughly deserves. With no visible weld beads, one tube appears to flow seamlessly into the next.
  • Direct Mount Chainguard
    No-one wants an oily or dirty chain anywhere near their clothes. So, since chains can get oily and dirty over time, we developed the Direct Mount chainguard. It's neat, unobtrusive and helps keep your clothes away from moving parts so that you arrive at your destination clean and fresh.
  • SIC 2.0 (optional)
    Easy to fit and even easier to live with, the optional Semi-Integrated Carrier 2.0 is the perfect way to extend the versatility of your CUBE bike. Strong and versatile, it's the ideal way to convert your bike to a tourer, take on the daily commute, or even go shopping with your bike. Have it your way.
