The tyre we use has a diameter of 584 mm (27.5") and is 42 mm (1.65") wide. If you wish to change the tyres, a width up to 44 mm would fit the Cowboy bike. You can find a recommended tyre directly on our website.

We can recommend the tube that you can purchase here.

Other inner tube models can work, too. You need to pick a model that matches the size of your tyres, i.e. 42 mm - 584mm or 1.65" - 27.5" for the original Cowboy tyres and have Presta valves. Replacing those valves with Schrader valves is not possible as they aren't suited for the Cowboy rims.

Because rubber can expand in certain cases, don't be surprised to see that 26" models can also fit 27.5" tires (e.g., the Schwalbe SV12 26" Presta inner tube is compatible). Brands usually mention several widths of compatible tires (e.g., 40 - 584 and 47 - 584). Simply make sure that 42 mm is included in the range of compatible widths.
