Valves - angled and straight
Inner tubes will have either a straight valve or an angled valve. Here is a brief description of the different types.
Angled Valves
An angled (bent) valve sticks out from the side of the wheel and makes it easier to inflate the tyre. It can be inflated the same as a normal bicycle valve. The angle of the valve can vary from 45° to 90° depending on the manufacturer. It is also known as a Schrader valve
Straight Valves
A straight valve is the same as the valves found on cars and most bicycles. It can be inflated the same as a normal bicycle valve. It is also known as a Schrader valve
The Schrader valve is the most universally used and known valve variety. They’ve been used on most motor vehicles and bicycles since their invention in 1891, courtesy of August Schrader.
A Schrader valve has a wide valve stem, into which a small valve core is inserted.
Schrader valve cores use a small spring that keeps the valve in the closed position.
When the valve’s spring is depressed, the valve opens, and air can pass through the Schrader valve.
Schrader valves are also referred to as American valves, as they were patented in the United States in 1893, just two years after their invention.
Inner tubes fitted with the above valves can be inflated with a standard hand pump, a selection of which can be found either below this listing or in the "Maintenance" section which can be accessed from the main menu.

Tyre Levers are needed to remove your existing tyres. The levers we sell are made of hard wearing nylon which will not damage your wheels.
A Pump is needed to inflate your tyres during fitting and to keep them inflated for improved performance and longer life.

Tyre and Tube Fitting Instructions
If you are just fitting a new inner tube:
- Remove your wheel from the pram, (not always necessary but makes life easier).
- Deflate the inner tube, once the air is out, pinch the tyre walls together to make it easier to lever off.
- Use a tyre lever, or two levers if your tyre is tight, and lever one side of the tyre off the rim.
- Remove the inner tube, and then you can take the tyre off completely.
- Check the wheel for any sharp objects / rough surfaces that could cause a puncture
- Check the tyre (if not replacing) for any sharp objects, do this by running your fingers around the inside carefully and remove foreign objects.
- Once happy, put one side of the tyre back on the rim
- Inflate your new inner tube just enough to shape it (a couple of pumps), this will make it much easier to fit - Don't try to fit a fully deflated "floppy" inner tube as you will probably nip it when fitting.
- Insert the inner tube into the tyre with the valve in line with the valve hole in the rim
- Push the valve into the valve hole
- Now you can put the other side of the tyre on the rim, if possible do this with your thumbs as levering a tyre on can sometimes pinch the inner tube. If you do need to use tyre levers be careful not to damage the new tube.
- Once the tyre is on you can inflate to the recommended PSI, you can use some Schwalbe Easy Fit to help the tyre slip into place under the rim bead. Its not always necessary but makes it easier. You can also use fairy liquid! but you'll need to clean that off after.
- Finally, check to make sure the tyre bead is seated properly on the rim.
- Now just put your wheel back on and you're good to go.
If you are replacing the tyre and the inner tube
- Remove your wheel from the pram, (not always necessary but makes life easier).
- Deflate the inner tube, once the air is out, pinch the tyre walls together to make it easier to lever off.
- Use a tyre lever, or two levers if your tyre is tight, and lever one side of the tyre off the rim.
- Remove the inner tube, and then you can take the tyre off completely.
- Check the wheel for any sharp objects / rough surfaces that could cause a puncture
- Once happy, put one side of the new tyre on the rim
- Inflate your new inner tube only just enough so it has a "bit of shape", this will make it much easier to fit - Don't try to fit a fully deflated "floppy" inner tube as you will probably nip it when fitting.
- Put the semi inflated inner tube in the valve hole of the wheel, and push the tube up into the tyre.
- Now you can put the other side of the tyre on the rim, if possible do this with your thumbs as levering a tyre on can sometimes puncture the inner tube. If you do need to use tyre levers be careful not to damage the new tube.
- Once the tyre is on you can inflate to the recommended PSI, you can use some Schwalbe Easy Fit to help the tyre slip into place under the rim bead. Its not always necessary but makes it easier. You can also use fairy liquid! but you'll need to clean that off after.

- Now just put your wheel back on and you're good to go.
TIGHT & UNEVEN FITTING TYRES:
- Another useful tip for fitting tight tyres, or tyres that you are having trouble sitting evenly on the rim, is to warm them up first, on a radiator or in a warm airing cupboard. This makes them more pliable and a bit easier to fit.
MIS-SHAPED TYRES:
Check out this video before fitting. Click Here for video.It is a good idea to warm up the tyre and manipulate it to get it as near to normal shape as possible. Mis-shaped tyres are fitted the same way as any other tyre, but special attention should be paid to the part of the tyre which is misshapen. Once the tyre is on the wheel you should inflate it a little at a time and make sure the misshapen part is not coming off the rim, if it is simply push it back into position and add a little more air.
ALWAYS KEEP MIS-SHAPED TYRES INFLATED TO THE MAXIMUM P.S.I.
