Start-Up

Kronfeld Tragfläche® is a German-engineered, innovative bike luggage carrier designed for versatility and durability. It features a telescopic design that expands to carry various items, from bags to child seats, while maintaining stability and precision. Crafted from high-quality stainless steel, the carrier is rust-resistant and built to last, with a focus on sustainability and practicality. It can be customized with multiple color options and is compatible with standard bike frames using M5 mounting points.

The Tragfläche® originated from founder Karl’s passion for kite surfing and a need for a practical transport solution. Developed through collaboration with universities and rigorous testing, the product combines engineering expertise with thoughtful design. It’s a lightweight, adaptable, and cost-effective alternative to traditional cargo bikes.

Our aim is to develop innovative products for sustainable and green mobility. We are currently building the company and working on the market entry. The main part of our business model is collaboration and cooperation with distributors and OEM Manufacturers. The tasks in this StartUp are quite diverse, and you will be challenged in many fields.
The focus of this internship will be on prototype development with the aim of fabricating and testing—a step on the way from concept to prototype.
