Cube Reaction Hybrid Youth 400 2020 - Electric Mountain Bike
Why shouldn't youthful enthusiasm be rewarded? That was our starting point for the Reaction Hybrid Youth, which uses the same technologies and frame construction techniques as our adult Reaction Hybrid frames. The oversized dimensions of the gravity cast down tube – along with the 1.5in head tube – help create a stiff backbone for a bike that, let's be honest, is going to be ridden with enthusiasm and quite likely a healthy disregard for risk. This is also home for the Bosch battery, whilst the smooth and powerful drive unit sits in its own housing under a cover that's accessed by a single screw. Internally routed cables keep gears shifting smoothly with minimal maintenance and, should your young ripper find themselves riding even more challenging lines, an upgrade to a stealth dropper post is quick and easy. Feed their enthusiasm – and see the positive reaction.
Building a perfectly proportioned, balanced e-MTB that handles brilliantly and fits smaller riders really well isn't easy, but our engineers love a challenge. The brand-new Reaction Hybrid Youth has all the features of our new adult Reaction Hybrid frames, in a 13.5in size that's ideal for the super-keen junior riders in your family. Powered by Bosch's superb fourth-generation CX drive unit, its 400Wh battery lives neatly inside the down tube and can be charged in situ, if needed. The 1.5in head tube, big cross-section down tube and oversized chain stays provide an efficient platform for the Bosch system to boost your young rider's power output, channelled through Shimano's smooth-shifting and incredibly reliable 10-speed Deore transmission to the 2.35in rear tyre. We selected powerful Shimano hydraulic disc brakes with a large 180mm front rotor, for dependable stopping power in all weathers. There's a kickstand mount for an easy upgrade, and it's even possible to fit a remote dropper post if you find you have an aspiring World Champ on your hands. And the Suntour XCM fork ensures that, however keen they get, there's plenty of help on tap to keep the rubber side down and the wheels rolling. Because enthusiasm should be rewarded, but safety's important too. The Reaction Hybrid Youth 400 has got it all covered, so you can get even more out of your family riding time...

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimeters for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but is like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the e mountain bike column.
