How do I know what size inner tube I need?

Check the numbers printed on the tyre sidewall. Match the wheel diameter and tyre width range to the inner tube listing.

What is the difference between Presta and Schrader valves?

Schrader valves are wider and similar to car tyre valves. Presta valves are narrower and commonly found on many road and performance bikes.

Can I use a slightly different inner tube size?

Inner tubes can cover a small range of tyre widths, but they should still match the listed size range. Avoid forcing a tube that is clearly too small or too large.

Are e-bike inner tubes different?

Many e-bikes use standard tube sizes, but heavier bikes can place more strain on tyres and tubes. Always match the exact tyre size and keep pressures correct.

Why does my new inner tube keep puncturing?

Repeat punctures can be caused by sharp objects still inside the tyre, rim tape issues, incorrect fitting, low pressure or a damaged tyre.

Should I replace the tyre at the same time?

If the tyre is cracked, worn, split or has embedded debris, replacing the tyre as well as the tube is often the safer option.

Replacement Bike Inner Tubes

Inner tubes are one of the most common replacement parts for bikes and e-bikes. Choosing the right size matters because a tube that is too small, too large or the wrong valve type can be difficult to fit and less reliable.

How to Match an Inner Tube to Your Tyre

Check the tyre sidewall for sizing before ordering. You will usually see the wheel diameter and tyre width printed on the tyre, along with whether you need a Presta or Schrader valve.
