Project Content
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.
