Extended 3-year warranty!

Kolos No.4 bikes will not disappoint you in any form. Whether a cross bike, or a more equipped trekking bike or a fully assembled expedition bike. All our models will be a reliable support on your journeys. Kolos No. 4 bikes are sold with an extended 3-year warranty.

Colossally up hill and down dale!

Kolos No.4 Gravel Bike corresponds to the current trend of robust “road bikes” for extremes, but moreover, offers a wide range of an individual specification.

The core is the light yet robust chrome-molybdenum (CrMo) frame which comes in three sizes, just for your figure. It is sturdy and flexible – especially designed for strenuous cycling.

We offer Kolos No.4 Gravel Bike in a recommended configuration, as it appeals to us. However, this doesn’t mean that its design is definitive. For example, this bike goes perfectly with the set of backpacking Ortlieb bags: Frame-Pack, Seat-Pack and Handlebar-Pack which can be selected in the Configurator.

If you take a close look at the Configurator, you'll see that the bike can be modified in a fundamental way using options from the wide range of fittings towards a simpler fitness bike, a more demanding adventure bike or a fully equipped bike for long-distance expeditions.

It's only up to you what adventure you want to experience with your Kolos bike and what's your financial budget.

If you don't find exactly what you need in our Configurator, please contact us and we'll prepare an individual quotation after we verify the compatibility, availability and price of the parts preferred.

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