    Aluminium Superlite, Gravity Casting Technology, Agile Ride Geometry, Boost148, Fully Integrated Battery, Advanced Internal Cable Routing, 1.5 Headtube, Kickstand/Fender/Carrier Mounting Points, 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. 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. 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. Size Split, The right bike should fit you perfectly. That's why we created Size Split. 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. Fender/Rack & Kickstand Option, It's the little details that make the difference. With the option to easily fit full length mudguards, a luggage rack and kickstand you can make your bike that little bit more versatile and easier to live with. Wet roads, stuff to carry or nowhere to lean your bike up when you arrive? No problem – we've got it covered. 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... 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. X-Connect, X-Connect is the simple way to attach a compatible ACID light to your CUBE bike. With a connector built into the headset and the wiring hidden in the frame, all that's left to do is attach the light, plug it in... and off you go. See and be seen, the easy way. Not identified
