Bike club. Rent instead of buying. Your bike flexibly with a subscription.

New school. New ways. New Bike.

When driving becomes a passion.

Do you still remember the moment your child rode alone for the first time? This radiance. This freedom. This ACADEMY upGrade 4 is the bike that takes this feeling to the next level - more control, more fun, more confidence on every path.

Developed as a consistent upgrade to the proven Grade series, the upGrade 4 combines everything that children really need: a bike that is light enough to master - and strong enough to grow with them.

For parents who don't make compromises.

We know: When your child is on the bike, you want to be safe. Hydraulic disc brakes at the front and rear ensure that your child comes to a safe stop at all times - in the rain, on gravel, downhill. No effort, no uncertainty. Just trust.

The light aluminum frame with age-appropriate geometry ensures that the bike does not overwhelm the child - but rather inspires them. Less weight means more control. More control means more courage. And more courage means unforgettable moments.

EQUIPMENT

Lightweight aluminum frame & aluminum fork – maximum rigidity, minimum weight
Age-appropriate geometry – perfectly tailored to your body size and driving experience
Hydraulic disc brakes VR & HR – reliable braking performance in any weather
8-speed chain drive with short rear derailleur – precise, smooth shifting for any terrain
Vario stem – Ergonomically adjustable for the optimal sitting position

The upgrade that lasts.

Children grow quickly. But the memories of the trips, the adventures, the first steep hills – they remain. The ACADEMY upGrade 4 is not just a bicycle. It is the companion for the years when little drivers become big personalities.
