How did Ziemi actually get started?
Aug 18, 2025
For my master’s program, I was given the assignment to design a solution for an e-bike manufacturer targeting food delivery riders in Los Angeles. They often ride in a hurry and in the dark. In L.A., there aren’t really bike lanes, which leads to many accidents. I came up with the idea that cyclists, just like performers on a stage, should be in the spotlight. That’s how the idea for Ziemi was born, derived from “See me”.
The concept of Biomotion isn’t entirely new in the cycling industry. Reflectors on pedals, in spokes, and reflective clothing have been around for a while. But to be visible, you need a light source. And by the time a car’s headlights catch you, the driver’s reaction time is already limited. Ziemi makes you visible earlier because you light yourself up.
I quickly realized that there was also a need in the Netherlands for a safer traffic environment. Due to poor or missing lighting, the number of cycling fatalities had risen to a record high, so I decided to bring Ziemi to the Dutch market. We optimized the business plan and go-to-market strategy at YES!Delft, and Ziemi was subsequently officially patented by Arnold & Siedsma.

Co-founder of Ziemi
Om Ziemi te lanceren, startten we in 2020 een crowdfunding campagne. Dit voorkwam een banklening en liet direct zien of er animo was voor ons idee. Binnen een maand verkochten we de eerste 500 prototypes en haalden €36.000 op. In het debuutjaar verkochten we 2000 stuks.
Verkeerspsycholoog Gerard Tertoolen vindt het idee achter Ziemi sterk. "Je bent goed zichtbaar en ziet een mens in plaats van een klein lampje. Dat is voor automobilisten fijn," legt hij uit. "Het heeft vooral een voordeel van dichtbij, want dan zie je wat de ander gaat doen. Een fietser kan onverwachte bewegingen maken en dat zie je door zo'n lampje dus sneller." 🤝
