There are a few steps to repair punctured bicycle tyre. First, you need to loosen the tyre. Use a spanner to help you unscrew the nuts. Then, put a screwdriver in between the tyre and the rim. Push out the inner tube.
Inflate the tube and put it in a basin of water.Submerge the whole tube.If the tube is leaking, there will be bubbles at the point of leakage. Put a pin into the hole and then take it out of the water. Dry the tube.
Next, inflate the tube again. When it is full of air, pull out the pin. Put glue on the hole. Let it dry and then put a plaster on the same spot. Make sure that it is firmly in place and leave it to dry again.
To check whether there are any more leaks in the tyre, inflate the tube again and put it into a basin of water. If there are no more bubbles, it means that there are no more leaks. Now you can put the tube back into the tyre.
