Driving is believing

A 4Wieler can view and test you at 4Wieler in the Innovation and Expertise center in Leiden. There you will receive the essential information about the unique characteristics of the bicycle and what they have as an advantage for you. Your safety comes first, which is why a test drive is mandatory and 4Wielers are not for sale through dealers. If traveling to Leiden is not an option for you, we can make an appointment at your home.

“Making a test drive is mandatory and free in Leiden. Together we will examine and decide whether you can safely enter traffic by bicycle.”
