This three-wheeler can be converted into a shopping cart in less than eight seconds. Instead of conventional ball bearings in the steering unit, we used iglidur® bearings and thrust washers. In addition, a plain bearing is used in the connection between the front and rear sections, which is largely responsible for the fact that the tricycle can be reassembled quickly. In both places, the bearings support large loads. That‘s no problem for the igus® bearings, which are also completely lubricant- and maintenance-free.
