Handy in case of flat tyre
I had a puncture while riding my bike and the tyre went flat. After going to a petrol station and filling it with air the product sealed the tube for two days, until tyre went flat again.
Good product with a video with clear instruction to change the tyre.
An excellent product!
Bravo
Quick and easy to change a tyre essential stock to keep the kids mobile
Inner tubes for £3 you can't beat this price anywhere. I bought 2 just in case the tyres pop so hopefully they work.
Seems to be made from good thick rubber. Time will tell how good these tubes are in the long run for puncture resistance and general wear and tear
Did what it said
Perfect
Upon fitting the inner tube to the tyre with some air in it, it seems the tube is longer than the tyre. It kind of folds a bit (BTWIN Foldable bike) after fitting.Who knows if it's still folder once fully inflated. So far it still holds the tyre and works....
Bought a pair for my fold up bike and sons BOX. These are superior to the cheap innertubes sold by other shops.
I think maybe on this occasion it would have been better to have paid for a better quality tube
I'm sorry to read that you have had a puncture.

Additional Product Information
Composition
Main fabric
- 10% Brass
- 90% Rubber - Isobutylene isoprene rubber - butyl
How to choose an inner tube
Check the information indicated on the sidewall of the tire (diameter and width). For example, 20 x 2.10 means your tire is 20 inches in diameter and 2.10 inches wide. On the tire sidewall, you will also find the dimensions in mm in ETRTO international units. For example, 50-406 means a tire that is 50 mm wide and has an inner diameter of 406 mm (approx. 20 x 2.00).
Removing an inner tube
Remove the old inner tube using B'Twin tire levers
Checks to carry out before installing an inner tube
Check the condition of your tire and replace it if necessary. Make sure no objects are lodged in the tire. Check the condition of your tire rim strip. A rim strip that is even slightly bent can cause punctures. Check that your rim does not have any other issues that could damage your inner tube.
Mounting the inner tube
Watch our video before you start. Pre-inflate the inner tube slightly to avoid pinching. Insert the valve, making sure you are using the correct valve for your rim. Put the inner tube entirely inside the tire so that it fits inside the rim. Take care not to pinch the inner tube when fitting.
Mounting the tire
Start mounting the tire at the valve. Finish mounting the tire at the valve to avoid pinching the inner tube. Never mount your tire with a screwdriver or a tire lever, as you risk pinching and puncturing the inner tube.
Inflating the tire
Inflate your tire carefully, to the pressure recommended by the manufacturer (visible on the tire sidewall in PSI or bars, 1 bar = 14.51 PSI). Regularly check that your tire is in the correct position as you inflate it.
Tip from the pros
To prevent any puncture from pinching and to achieve the best performance, we recommend checking and, if necessary, pumping up your front tire before each ride.

Storage instructions
Carry your inner tubes in a container to protect them from getting punctured (B'Twin carry case, original packaging, etc.).
Care instructions
To find out the size of your wheels, check the information printed on the tire wall. Always carry a spare inner tube and a pump.
