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
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.

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.
Schaefer Valve inner tube is authentic, durable and long lasting. Would recommend to use Schaefer products for B’TWIN
I have two Tilt 120 Folding Cyles. It's something with these tubes. They don't hold air well for even a week if I am not using the cycles and every time there's a flat tyre it's not because of a nail or something external. The puncture is always near the valve where it's pressed against the rim of the wheel. And once that is the case, any cycle repair shop you visit will advise you to change the tube because the fix won't last. Now I have to change tubes on all 4 tyres because I cannot trust when they'll go out. 2 front tubes (of the 2 cycles) gave in when I rode them a few days ago). I am going with a diff. brand for the tubes this time. If not for the tubes or the frequent loss of air pressure/punctures, I'd totally recommend Tilt 120 to everyone, including adults. What a shame! This must have been fixed by now.

Check the information indicated on the sidewall of the tyre (diameter and width).For example, 20 x 2.10 means that the tyre is 20 inches in diameter and 2.10 inches wide.On the tyre sidewall you will also find the dimensions in mm in ETRTO international units. For example, 50-406 means a tyre that is 50mm wide and has an inner diameter of 406mm (approx. 20 x 2.00).
Remove the old inner tube using B'Twin tyre levers
Check the condition of your tyre and replace it if necessary.Make sure no objects are lodged in the tyre.Check the condition of your tyre 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.
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 tyre so that it fits inside the rim.Take care not to pinch the inner tube when fitting.
Start mounting the tyre at the valve.Finish mounting the tyre opposite the valve to avoid pinching the inner tube.Never mount your tyre with a tool or a tyre lever, as you risk pinching and puncturing the inner tube.
Inflate your tyre carefully, to the pressure recommended by the manufacturer (visible on the tyre sidewall in PSI or bars, 1 bar = 14.51 PSI).Regularly check that your tyre is in the correct position as you inflate it.
To prevent any puncture from pinching and to achieve the best performance, we recommend checking and, if necessary, pumping up your front tyre before each ride.
