16 Inch Bike Tubes

16 inch bike tubes are commonly used on kids’ bikes, some folding bikes, and small scooters. These tubes are designed to fit tyres with an ETRTO inner diameter of 305mm, ensuring a secure and reliable fit when installed correctly.

Understanding 16 Inch Tube Sizing

Tube sizing can be confusing, especially since it's often written in different formats. A typical 16" tube might be labelled 16 x 1.75–2.125, meaning it will fit any 16" tyre with a width between 1.75" and 2.125". You may also see metric sizing such as 47-305, which refers to a tyre that is 47mm wide and has a 305mm inner diameter. The most important thing is to match the ETRTO diameter (305mm for most 16" tyres) and choose a tube that fits the width range of your tyre. All our tubes in this category are made to suit standard 305mm diameter tyres.

Valve Types

We stock a variety of valve options to suit different rim types and preferences, including:

• • Schrader (car valve) – common on kids’ bikes and easier to inflate with standard pumps
  • Presta (skinny valve) – often found on higher-end folding bikes or older road bikes
