Project Content
Kronfeld Tragfläche® is an innovative startup dedicated to revolutionizing mobility through sustainable, user-friendly solutions. Our core mission is to empower individuals to embrace cycling as a practical and eco-friendly alternative to traditional transportation methods.
Our flagship product is an extendable luggage carrier designed to upgrade regular bikes and e-bikes, offering flexible, spontaneous, and sustainable transport solutions. By providing a viable alternative to cargo bikes and trailers, we aim to make cycling more accessible and versatile for everyday use.
We are driven by a commitment to sustainability, resource efficiency, and simplicity. Our research and development efforts focus on creating innovative low-tech solutions that align with our vision of reducing environmental impact while enhancing mobility.
As part of our growing team, you will contribute to shaping the future of urban transportation and help us build a community around eco-friendly mobility. 

This internship offers a diverse range of tasks, focusing on marketing and brand awareness.
You will primarily assist in digital and analog marketing, creating content for social media, blogs, and newsletters, and engaging with the cycling community. If you're passionate about biking and planning bike trips, you’ll have the chance to report on them through digital and analog media as part of your internship. You will also help plan and organize events, fairs, and promotional test events.

Your tasks will include:
  • Supporting marketing campaigns to promote our products.
  • Planning and coordinating events and test promotions.
  • Creating content for social media and other channels.
  • Conducting market and competitor analysis.
  • Assisting with public relations and media outreach.

If relevant research or development projects arise, you will have the chance to contribute and potentially use them for your thesis or university project.
