How do I know if my bike has an inner tube?

The best way to check what size inner tube you need is to look on the sidewall of your tyre. Tyre manufacturers print the size on the sidewalls, so look out for numbers such as ‘700x23c’ for a road bike, or ’26×1. 75′ which is for mountain bikes.

Are bike tires and tubes the same size?

The size is almost always written somewhere on the sidewall of the tyre. Inner tubes typically state a wheel diameter and width range for which they will work, e.g. 26 x 1.95-2.125″, indicating that the tube is intended to fit a 26 inch tyre with a width of between 1.95 inches and 2.125 inches.

Can you change an inner tube without removing the wheel?

A flat tire may be repaired either by replacing the inner tube or by patching it. To replace the inner tube, you must remove the wheel from the bicycle.
