CUBE ACID 240 HYBRID ROOKIE PRO 400 ACTIONTEAM

The Acid 240 Hybrid Rookie gives younger riders an extra power boost, so they can tackle longer family rides and keep up with the grown-ups. Making use of the same technologies as our full-size e-mtbs, it features a Bosch Active drive unit coupled to Shimano's easy-to-use 9-speed gears. Suntour's XCT JR fork is designed specifically with younger, lighter riders in mind and helps smooth out the trail ahead. A kid-friendly cockpit and saddle make for a super-comfy ride position. And there's a set of powerful hydraulic disc brakes, for safe stopping. Put the spark back in your family rides...

Frame description
It's fair to say that Bosch didn't have perfectly proportioned kids' bikes in mind when they designed their world-beating drive systems, but that hasn't prevented us from neatly integrating it into the Acid 240 Hybrid Rookie's frame. Using the same design and construction techniques as our adult hybrid mtbs, we've built a junior hybrid that's both fun to ride and safe as well. Internal cable routing significantly reduces maintenance, and we even included mounts for a CUBE kickstand.
