No.6 folded


Such are the Kolos No.6 folding bikes.

The Kolos No.6 folding bike is based on the now classic concept of folding bikes with 20” tyres (406). This type of bike is becoming more popular due to the fact that while maintaining a small size of 87x38x68 when folded, it is comfortable to handle and provides a good riding experience. The Kolos No.6 is recommended for cyclists, both men and women with a height of 150 to 190 cm, who want to use the bike in combination with public transport, a train or a car. A folding bike is suitable for owners of small flats, who struggle with space and where parking a normal size bike is complicated.

Choose your favourite colour, suitable installation and equipment from our wide-ranging offer in our configurator and create your Kolos according to your desire, needs and budget. We will build you a folding bike in your preferred colour and fitted with accessories that will fit you like a tailored suit.

In addition to the configuration options, the level of processing and the favourable weight (12kg), the Kolos No.6 folding bike excels in its practicality of the selected parts. For example, using the front hub with standard 100 mm spacing and fitting both of the wheels with standard 36 spokes makes the otherwise problematic service of a folding bike much easier while maximizing wheel strength.

When folding, then only with Kolos!
