Life on two wheels

Kolos No.4 expedition bike meets the conditions for use for long-distance cycling, the expeditions to the edge of the world with the full equipment for a long-term stay on the way. Zbyněk Michal from the ZigZagCycling project put the frame set Kolos to a great load test on the road from Ústí nad Labem to Japan covering 19,000 kilometres. The bike Kolos No.4 was also a reliable tool for the 7,000 km long Silk Road and many other expeditions across Europe.

The core is the light yet robust frame from a chrome-molybdenum steel (CrMo) which comes just for your figure. It's sturdy, flexible and equipped with all the necessary screw fittings for installation of all equipment.

We offer the expedition bike Kolos No.4 in a recommended configuration, as it appeals to us. However, this doesn’t mean that its design is definitive. Choose the gear shifting according to the intended use, supplement the bike with top-class Ortlieb bags or replace the handlebars for those which would suit you more.

If you take a close look at the Configurator, you will see that the bike can be modified in a fundamental way using options from the wide range of fittings towards the lighter gravel bike and the robust electric bike with a unique Pendix drive and Alfine gear shifting.

It depends on the adventure, which you want to experience with your Kolos and on your financial budget.

If you don't find exactly what you need in our Configurator, just contact us and we will prepare an individual quotation after we verify the compatibility, availability and price of the parts preferred. The same applies also to the installation of other nuts countersunk in the frame, if 2 screw fittings for the beverage baskets are not enough.

The result will always be a completely individual product – the bike that's been designed for you and your adventures only.
