All about inflating your bicycle tyre – BESV

Need to inflate your bicycle tyre? This is the right way to do it!

It seems so simple, and in fact it is: inflating the tyre of your BESV e-bike. You just have to do it right to be able to enjoy your bicycle to the full. For example, it is very important that you use a pump that fits the valve of the e-bike. Another important question: how much pressure should the tyre have? This article answers these questions and explains step by step how to inflate a tyre correctly.

Why it is so important to inflate your tyre properly

An incorrectly inflated tyre can cause many different problems. This is because tyres are specially designed to function at a certain air pressure. A tyre that is inflated too hard or too soft is more likely to get punctured, which is the last thing you want, right?

It is also important to find the right balance between performance and comfort. Are you inflating the tyre too soft? Then your wheels will have more rolling resistance, which means you’ll have to pedal harder and won’t last as long on a full battery. On the other hand, tyres that are too hard give too little suspension, which means that you will feel every bump in the road in your wrists. Not cool!


French valve (Presta)

The French valve (also called Presta valve) is somewhat narrower than a Dutch valve and is equipped with an extra turning cap. Because the diameter of the valve is smaller, the hole in the rim (through which the valve protrudes) is also smaller. Ideal for sporty bikes with thin rims, such as racing bikes and sporty e-bikes. Our BESV Trekking models are also equipped with French valves.

Car valve (Schrader)

Do you own a mountain bike, such as a BESV e-MTB? It will be fitted with a car valve, or Schrader valve. This valve is extremely robust and is therefore ideal for all your off-road adventures. In addition, it is used worldwide for everything (cars, motorbikes, mopeds and appliances), so you can find a pump for this valve at every petrol station.

How much pressure/bar should a bicycle tyre have?

As mentioned, the right tyre pressure is very important. But what is the right tyre pressure? This varies per type of bicycle and per type of tyre:

  • For city bikes, it is usually between 2.5 and 3.5 bar.
  • For mountain bike tyres, keep between 1.4 and 2.6 bar.
  • For road bikes and sporty e-bikes the ideal range is between 6.0 and 9.0 bar.

These values are only indicative. The recommended tyre pressure is always stated on the tyre itself. If you keep the middle ground between these values when inflating, you are actually always on the right track. Then you can decide for yourself what you like. For example, heavier people will often want to inflate their tyres a little harder. Are you going to ride in the mud or snow? Then it is smart to go for a lower tyre pressure, because you have more grip then.

Step by step inflating the bicycle tyre

Now that you know which valve your tyre has and what the ideal pressure is, the fun part is done: Inflating your tyre step by step. We have listed the steps below. They are the same for each type of valve, except for steps 2 and 4. They work slightly differently with French valves.

Step 0: The right pump

Before you can start inflating, you need a good pump with a head that fits the valve. Most modern bicycle pumps (with a button head or a screw head) fit every type of valve, otherwise a adapter nipple offers a solution. We also recommend a pump with a pressure gauge, so that you can immediately see the tyre pressure. It is also smart to use a pump with a hose (or a tube with a portable pump). That way you run the least risk of damaging the valve.

Step 1: Turn down the valve

First turn the valve downwards. This ensures that you have good access and is the easiest way to attach the pump head.

Step 2: Unscrew the cap(s)

Then unscrew the cap. Do you have a French valve? Then also unscrew the valve. Be careful, as turning too far will loosen the whole inside and all the air will come out straight away. That is not the intention.

Step 3: Start pumping!

Now put the pump head on the valve and pump the tyre until it is nicely inflated.

Step 4: Tighten the cap(s) again

The last step in inflating a bicycle tyre is to screw the cap back on. With a French valve you must also screw back on the extra cap. Check (especially with French valves) the rim nut to be sure. This should always be tightened to prevent leakage at the valve.
