What customers say

"The stable 4Wieler is the solution for me"

“The clear folder has been thoroughly researched. Mr. de Bruin can't wait for the custom made 4Wieler to be delivered. "I am still reasonably healthy, but there is always wind and my balance is deteriorating. There are narrow polder roads with larger vehicles than before. I no longer feel comfortable with this. The stable 4Wieler is the solution for me. different, but it comes almost naturally, I really advise everyone to transfer early if you are afraid of falling. ”

Aad de Bruin - Medemblik

"I can't fall anymore and I'm very happy about that"

Recently Mrs Rovers (93) can be seen cycling again in Uden. A miracle, written off by everything and everyone because of her back and rheumatism, you can watch her 'rush' by on a duo bike, enjoying and chatting. "I really am there, just write it in large letters, very happy about that. The movement, the stability, the ease and the ultimate feeling that the fear of falling has disappeared. I am very surprised that I have not yet found another four-wheelers pass by."

Marietje Rovers - Uden

"A safe bike ride to Utrecht is possible again"

Until recently, Mrs. Willemsen with a spinal cord injury could no longer experience the environment moving. "I want to cycle for the rest of my life. Talking will come naturally. I have to and want to keep moving. Sitting still is not for me. The fear of falling in a tricycle remained. It didn't feel completely stable. That's why I "I kept looking for something that is more stable. And then luckily I ended up at 4Wieler in Leiden. A safe and familiar bike ride to Utrecht is possible again. I'm feeling the weather and it's no longer a problem."

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.
