The history
The origin of 4 WielerThe history of the 4Wieler
The most fun and only really safe bike that you can’t fall with.
It has already won several awards, including the prestigious Dyson Sustainable Design Award and the audience award during the Graduation Show of the Design Academy, both during the Dutch Design Week in Eindhoven. After these successes, Lennart and his father Herbert Vissers decided to take the Feetz into production in 2006.
Soon there were also many questions to make a stable adult tricycle or disabled bicycle in addition to the dynamic tricycle Feetz. But with three wheels it turned out not to be possible to make a sufficiently stable and safe bicycle that really helps people with stability problems.
This is how the SupportBike was created with four wheels. So narrow that the bike fits through any door. But much more stable than tricycles for adults. 4Wieler was finally created at the beginning of 2010, after the splitting of the dynamic tricycle Feetz and the stable four-wheeler SupportFeetz.
After the split, the SupportFiets continued under the banner of 4wieler to provide tailor-made solutions to customers with the same care, passion and enthusiasm if necessary. 4Wieler attaches great importance to personal contact with customers and we are happy to visit you without obligation to introduce you to the 4Wieler of your choice and to try out the bicycle in your own familiar environment.
What customers say
The Duofiets
In 2011, the 4Wieler DuoFiets was designed and put into production. On a 4Wieler DuoFiets, the driver and passenger sit comfortably next to each other, the driver on the left operates the bicycle and watches the traffic. The passenger next to it can choose its own gear and can pedal along, but that is not necessary. Nice and healthy exercise in the open air is the motto of 4Wieler and that in a position just like on a normal bicycle: on a saddle and pedaling down. If the co-driver needs more support, a backrest with armrests can be mounted behind the saddle. For the feet, there are also balance pedals with foot straps. And for the passenger who can no longer cycle, there is a seat or chair and a footrest instead of the saddle. The Duofiets also steers and rides very lightly and if both riders can cycle then pedal assistance is not immediately necessary. At the beginning or at any time later, the Duofiets can be equipped with electric pedal assistance. Like all 4-wheelers, the Duofiets also distinguishes itself with its well-thought-out technical solution and the unique spring-loaded front wheel suspension in combination with a beautiful, modern design. A duo bike is multifunctional: baskets, boxes, bins and suitcases made of reed, wood, aluminum and leather can be mounted on the front and/or back. Also child seats and benches and cargo trays by the way.

From the Duofiets to more

Then the Duofiets can be transformed into a Duo-Picnic-Fun bike, a Duo-Sportive Senior Bike, a 7-person Family Holiday bike, a Duo-Meeting Bike (for 2 or 4 people) or a Duo-Vrachtfiets in just a few steps. There are plenty of ideas for the coming years to develop new products that contribute to healthy and pleasant mobility for everyone up to old age. Below are two images of the 4Wieler 3 wheel tilt bike: the sporty alternative to a cargo bike. This will be available soon.
