2023 Cube Reaction Hybrid Performance 625


Take the road less travelled, just because you can. The new Reaction Hybrid Performance uses the power assistance of Bosch’s Performance Line motor to help take you to new places. Elegant Cube design, a trapeze frame option and sizesplit sizing means there’s a Reaction Hybrid Performance with your name on it. Where will it take you?

Completely new for 2023, Cube’s versatile and rugged Reaction Hybrid Performance is built around Bosch’s quiet, powerful Performance Line motor with 75Nm torque. It’s Bosch Smart System-equipped and capable of accepting a battery up to 625Wh for worry-free longer rides. There’s a clever flat mount for an optional kickstand, an option to add an integrated frame lock, and mounting points for a multi-tool or lock under the top tube. We even incorporated a tool into the seat clamp, and internal cable routing and a new speed sensor setup translate to clean lines and minimal maintenance. And, with a Trapeze frame option and SizeSplit, it’s easy to find the perfect fit for you.

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…

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.

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.

Cables connect your handlebar controls to vital components like gears and brakes, but there’s no need for them to get in your way. With Internal Cable Routing we’ve reduced clutter and maintenance by running cables through the frame, keeping them out of the way of dust and water contamination – or damage from abrasion – as well as cleaning up your bike’s appearance.

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.

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.

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.

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…
