All new Cowboy bikes come with a 2-year warranty (1 year for Circular bikes). If you would like to extend this period by 1 year, you can do so on our website when purchasing your Cowboy bike or anytime through your Cowboy app, provided you are still under warranty. Warranty extensions can only be purchased once per bike. If the previous owner has already extended the warranty, it will not be possible to extend it again.
