FAQs
Can I use these for my bike?
These are specifically designed for stroller and pram wheels. While they share size characteristics with some small children's bikes, please verify your specific wheel size before use.
Do I need a special pump?
No, the bent Schrader valve is the same standard valve found on car tires and most bicycles, allowing you to use almost any standard pump.
How do I know which size I need?
Check the sidewall of your existing stroller tire; it will list the dimensions (e.g., 12.5 x 2.25). If it matches our listed sizes, these tubes will fit.
Why is the valve bent?
The bend is intentional to make it easier to attach a pump head to wheels where the frame or brake assembly might otherwise block a straight valve.
Is it difficult to install?
It is a standard maintenance task. If you can remove your stroller wheel, the tube replacement is straightforward, though using plastic tire levers is recommended.
Troubleshooting
Tube will not hold air after installation
Check that the valve core is tightened securely and ensure the tube was not pinched between the tire bead and the rim during installation.
Tire appears lumpy or uneven
Deflate the tube slightly, massage the tire around the circumference to ensure the tube is seated correctly, and then re-inflate slowly.

Setup, Compatibility & Care
To install, you must remove the wheel from the stroller frame. Deflate the old tube completely, pry the tire edge from the rim using a plastic tire lever, and remove the faulty tube. Before inserting the new tube, check the inside of the tire casing for thorns, glass, or debris that may have caused the previous puncture. Partially inflate the new tube before seating it within the tire to prevent pinching. Ensure your tire markings match the supported sizes (12.5 x 2.50, 12.5 x 2.25, or 12 1/4) before attempting installation. Regularly inspect tire pressure to avoid pinch flats and keep the valve caps tightened to prevent dust entry.
