Three reasons for Tragfläche®

Flexibility and more transport capacity

The Kronfeld Tragfläche® gives you the freedom to adjust your bike as needed. Whether you need to transport little or suddenly require more space – with just a few adjustments, you can extend the cargo area and create room for everything you want to carry on the go. For families, the Tragfläche® is particularly practical, as it offers space not only for a child or child seat but also for groceries, sports equipment, or other items. And when the extra space is no longer needed, you can easily retract the Tragfläche® – your bike remains slim and maneuverable. This flexibility makes your bike the ideal companion for spontaneous transport – without the limitations of fixed cargo bikes or trailers.

Cost-effective and sustainable alternative

Our extendable cargo rack is the cost-effective and eco-friendly alternative to expensive cargo bikes and cars. Made from stainless steel, which can be endlessly recycled (recycling without end), and its robust construction that lasts a lifetime, it reduces your resource consumption and lowers global waste. Our solution supports sustainable production practices (SDG 12) and eases urban traffic, contributing to sustainable urbanization (SDG 11). By efficiently using existing resources and creating a flexible, space-saving transportation option, it also strengthens local industry, innovation, and infrastructure (SDG 9). This way, you can transport more spontaneously – without compromising on eco-friendliness or budget.

Practical for everyday use and space-saving

The Tragfläche® offers a versatile solution for more transport capacity without permanently enlarging your bike. Thanks to the telescopic mechanism, the cargo rack can be extended in just a few seconds, keeping your bike compact and maneuverable. This allows you to move freely in the city, pass through narrow passages, and easily use public transport, elevators, or bike parking – a major advantage over bulky transport solutions. Especially in urban areas, where every centimeter counts, the Tragfläche® enables spontaneous and flexible transport without limiting your mobility. Your bike remains practical for everyday use and always ready for action.
