• 24 Inch Inner Tubes

    Discover our complete selection of 24-inch bike inner tubes, designed to cover every riding style and compatibility on the market. From kids’ bikes to mountain bikes, urban bikes, cargo bikes, e-bikes, and wheelchairs, you’ll find the inner tube perfectly matched to your tire. Our range spans a wide spectrum of tire widths and includes all major ETRTO standards used in 24-inch wheels, ensuring a precise and reliable fit.

How to choose the right 24-inch inner tube

The 24-inch size is unique in the bicycle tire world because it includes several different internal rim diameters. That’s why it’s essential not to rely solely on the “24-inch” marking, but to always check the ETRTO size printed on your tire sidewall (for example: 50-507 or 47-559). This number guarantees proper compatibility between your tire, rim, and inner tube.

Our range of 24-inch inner tubes covers all common use cases found on the European and international markets, organized into several main categories.

1. MTB, Junior, BMX & Compact Cargo standard – ETRTO 507

This is the most widely used 24-inch standard, commonly found on kids’ and youth bikes, 24-inch mountain bikes, BMX bikes, many city bikes, as well as some compact cargo bikes and electric bikes.

In this category, you’ll find inner tubes compatible with a broad range of tire widths, from versatile everyday sizes (24x1.50, 24x1.75, 24x1.90, 24x2.00, 24x2.10) to wide and extra-wide tires (24x2.25, 24x2.35, 24x2.40, 24x2.60, 24x2.80, 24x3.00, 24x3.50, and up to 24x4.00).

2. Narrow profiles, specialty bikes & wheelchairs – ETRTO 520, 534 and 540

These sizes are primarily used for manual or active wheelchairs, certain junior bikes with narrow tires, as well as older or specialty bicycles. The corresponding inner tubes are slimmer and feature a different internal diameter than the MTB standard.

Common configurations include:

  • ETRTO 520: 24x0.90, 24x1.00, 24x1 1/8
  • ETRTO 540: 24x3/4, 24x1.00, 24x1 3/8 (very common on wheelchairs)
  • ETRTO 534: the classic 24x1 1/2 size

3. The specific ETRTO 559 case

Some less common setups use a 559 internal diameter, such as 24x1.95 (47-559). These inner tubes are not interchangeable with 507 standards and must be selected strictly according to the exact ETRTO size printed on the tire.

Why inner tube quality matters

Whether it’s for a child’s bike, the reliability of an electric bike, or the daily use of a wheelchair, inner tube quality is critical. Our inner tubes are selected for their elasticity, long-term air retention, and reinforced valve bonding (Presta or Schrader, depending on the model), helping reduce the risk of punctures, pinch flats, and premature air loss.

  • Narrow profiles: 24x3/4, 24x0.90, 24x1.00, 24x1.10, 24x1 1/8, 24x1 3/8, 24x1 1/2

Pro tip: Before ordering, always check the valve type required by your rim and confirm the exact ETRTO size printed on your tire. This ensures perfect compatibility and lets you get the best performance out of your 24-inch inner tube.
