This Bike Carrier Can Carry More.

And is adaptable.

... just like you. It allows you to transport up to four bicycle bags and can hold up to 40 kg. And as if that wasn't enough, you can also take a child with you in addition to your luggage with the Kronfeld Tragfläche®. There is enough space for everything and everyone.

That's why it's called a trip.

The Tragfläche® teaches your luggage to fly.

Here the Tragfläche® is fully packed on the way to a trip to the sea. If you go camping or do a sport that requires a lot of equipment, transporting it by bike is no longer a problem.

That’s why we always say “Ready for takeoff!”

We're getting started with Startnext!

With our visit to Eurobike in July 2024, we are also starting our Startnext crowdfunding campaign. The goal is to realize the first series production. With your support, you can make this dream come true and also be one of the first to hold the Tragfläche® in your hands.

Every contribution brings us closer to our goal. We thank you in advance!

The future rides bicycles.

And your luggage is in the future too!

Thanks to the easy handling and the infinitely variable adjustability of this luggage rack wonder, your normal bike can compete with cargo bikes. Hand on heart: There's usually not much else you want to take with you. With the Tragfläche®, these situations no longer tempt you to take the car. The environment will thank you, and so will your nerves.

I don’t have a car. The Kronfeld Tragfläche® gives me the opportunity to stay environmentally friendly and still be able to get to all the different kite spots with all of my kite gear. I can start in Wiek and ride to the other side oft the boden and kite there – without having a car!

Finally I can go shopping with my child straight after nursery without a bike trailer.
