Unfortunately, a flat tyre is something that can happen to any of us.
The terrain (thorns, brambles, glass, nails, etc.),
or the way the bike is used (jumping over obstacles such as rocks, steps, curbs, potholes, etc.),
are the most common causes, respectively, of flat tyres due to a puncture (small hole) or pinching (small grooves close together).
On the other hand, if a flat tyre is a frequent occurrence, this could be because:
- The bike was improperly assembled at the factory, leaving the tip of one of the spokes exposed, which is puncturing the inner tube.
- The tyre or the inner tube is faulty (porous)
- A previous puncture was improperly repaired and a foreign object (thorn, bit of glass, metal shard, etc.) got into the rim or the tyre.
It's important to properly diagnose the flat and make sure the tyre and wheel rim are free from any foreign objects before doing the repair.
You don't know how to put a tyre on or take one off, how to repair or change an inner tube?
1. The simplest thing to do is not to touch your wheel and use a can of puncture repair foam as a temporary solution:
Screw the end of the sealant tube onto the valve of the flat tyre (valve should be in the lower position) and squeeze and hold to inject the foam into the inner tube. The tyre should become full and firm once more, allowing you to get back home safely.
2- If you've purchased our €1 breakdown insurance, you can have your tyre repaired at any Decathlon workshop.
3- To repair or replace the inner tube yourself, please refer to one of the video tutorials which you'll find below.
