Cube Acid 240 Hybrid Youth 400 24w 2020 - Electric Mountain Bike

We're not going to bore you with all the details, but let's just say that fitting the Bosch drive system and battery into a mountain bike frame suitable for kids isn't as straightforward as our engineers have made it look. A long experience of working with this superb drive system has given them the knowhow to build an exceptionally neat aluminium frame around it, putting the drive unit in precisely the right position for the best handling and semi-integrating the battery into the down tube for a sleek, elegant look. There's a tough 30.9mm seat post, internal cable routing to keep gear shifting clean and precise without the need for fiddly maintenance, and we even included mounts to fit a CUBE kickstand. All that's left to do is for your junior rider to jump on, and show the adults how it's done.
Why should adults get to have all the fun? The Acid 240 Hybrid Youth brings the power and versatility of our renowned e-bike range within reach of the youngsters in your family, giving them an extra power boost so they can tackle longer rides and keep up with the grown-ups. Making use of the same technologies and design features as our full-size e-MTBs, it features a Bosch Active drive unit with Purion controller, and a 400Wh battery for long-lasting power. We won't bore you with all the details, but let's just say that fitting the Bosch drive system into a mountain bike frame suitable for kids wasn't as straightforward as our engineers have made it look. It's all designed with safe handling and our usual emphasis on durability in mind, so your kids can enjoy the ride and you can too, knowing that we've taken care of all the details. The Suntour XCT JR fork is designed specifically with younger, lighter riders in mind and helps smooth out the trail ahead, while Shimano's easy-shifting 9-speed transmission has the range your junior rider needs to make light work of any climb. Put the spark back in your family rides, and get your child an Acid 240 Hybrid Youth...

* 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.
