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. 
This internship will focus on marketing and brand awareness. You will accompany us and plan events, fairs, and promotional test events. You will support our marketing team, and if we identify a research or development project, you will have the option to utilize your effort for your own project.
