Read more
The Solo Support bicycle from 4Wieler is an innovative bicycle with
stability and sturdiness as the most important property. The Support bicycle is a sturdy bicycle for 1 person that cannot fall over and when folded it serves as a rollator.

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.
