Folding the bike

You can fold the bike within a few seconds thanks to the smart design. For example, you can use it as a walking aid, which is useful for shopping, walking or when you have to take the train. Due to the support and stability that the 4 wheels offer, it is also very easy to get on and off. With the parking brake you have support on the bicycle instead of the other way around, so the risk of falling is minimal.

Easy to store

The Solo Support bike from 4Wieler is only 66 centimeters wide and fits easily through any door. Doors in the Netherlands are generally between 70 and 90 centimeters wide, so you still have 4 centimeters of clearance. When folded, the bike only takes up 120 x 66 centimeters.

"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

"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."
