You can then push the valve stem (attached to the tube) through the rim and get most of the tube out in the open. The valve needs to be taken apart, which really only means screwing off one ring. Now that the tyre is open on one side you can reach for the tube.
The moment you place the third lever the second one usually drops and the rest of the lifting can be done by hand. (A bit further if the tyre bead is very tight.) Repeat that for a third lever. After the first one is in, you turn the wheel slightly and about 10 cm further you place another tyre lever.
You wedge the lever between the tyre and rim and once it is placed, you attach the other end to the spokes. Now you need to lift one side of the tyre off the rim. It can stand on the saddle and handle bars. You start by turning your bicycle upside down. Tyre levers, patches, a piece of sand paper and vulcanising glue. It may be a small box, but it contains everything you need. You don’t need it to repair a puncture and if I have trouble with a valve, I just buy a replacement valve. The box also contains valve rubber, but I wouldn’t know what to do with that. The box contains three tyre levers, a number of self-adhesive rubber patches, sand paper and tube solution (vulcanising glue). Simson, type “Normaal” meaning standard or quite obviously ‘normal’. The only tools you need fit in a very small repair box that virtually every Dutch family has in the house. Not only the Dutch bicycles have a classic look, the tool boxes have a very 1930s feel as well. So how can we repair a flat tyre if we don’t even know how all that works? Easy: we don’t remove the wheel. Never mind the enclosed chain case that would also be in the way. I really haven’t a clue how it works exactly, but both the hub gear and the brakes are in there somehow. Dutch bicycle wheels, however, cannot be removed easily. One of the many bicycle shops is of course happy to do the required maintenance on your bicycle, but repairing a puncture is considered so easy, that everyone should be able to do that. But there is one thing that almost every Dutch child learns to do at a young age: how to fix a flat tyre! A flat tyre. So the Dutch generally perform almost no maintenance on their bicycles themselves. Dutch bicycles require almost no maintenance.
