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

We can recommend you the tube that you can purchase here.

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

Because in certain cases the rubber can expand, 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). Also, 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.
