I don’t know about you, but nowadays I wear my bike helmet every time I want to go out for a ride. 


Because I have had my fair share of road bike accidents in the past. And I know what it feels like to fall from a bike and hit my head on the ground. It’s such a painful experience.

You see, you have no idea what the terrains are like out there. Accidents happen. People either die or survive. But if you, too, can wear a helmet before you hit the ground running, you can cycle with confidence knowing you’ll be okay if anything happens. 

My advice on buying a helmet is just one thing. You also need to make sure you know how to adjust the straps to get a snug fit. So in this article, I’ll show you how to do that – even if this is going to be your first time to own buy a helmet for your bike. 

Are you ready to learn? 

Let’s get started. 

Start by Getting the Size Right

Before we look at how you can adjust the straps of your bike helmet without trying so hard, it’s important to make sure that you pick the right size. 

To do this: 

  • Use a clothing tape to measure the size of your head. Of course, you can use a string if you don’t have a tape measure. Whatever you use, make sure it passes above your eyes. 

Once you have the right measure, visit the nearby shop, and get a helmet that corresponds to the size of your head. 

Now that you have the right measurement and your helmet with you, let’s look at how you can adjust the strap. 

Step 1 : Tighten Your Hair

Long hair can make your helmet not fit as expected. So it’s important that you tighten your hair well at the back of your head. You may also want to consider having a helmet that provides space at the back for a ponytail if you happen to have one. 

Step 2 : Wear Your Helmet

Wear your helmet. Make sure it’s standing at least two fingers width above your eyebrows. This is also a good test if you want to determine if it is the right size for you. A snug should make you feel at peace that you have the right size. 

Step 3: Pull Down The Helmet Straps

The straps are attached to the helmet so you just pull them down, forming a Y or a V- shape at the ears. The length of the straps needs to be even on both sides and should not have a twist on them. 

Step 4 : Adjust Helmet Straps

Begin to adjust the straps depending on how the helmet feels on your head. You could either loosen or tighten them. For some designs, the straps are easily flexible, which makes it possible for you to stretch according to the size of your head. However, you may have to do this manually for others. 

To tighten the helmet, pull the Y-shaped straps down and push the slider upwards. If you want to loosen it, push the slider downwards. 

Step 5 : Buckle The Strap

Move to buckle the strap. A good fit implies that not more than two fingers can go through the space between the chin and the chinstrap. It should also be cantered right below the chin, not too far away from the neck. If you feel any discomfort, loosen the straps a little bit. By fastening the chinstrap well, the helmet cannot move front or back. 

Step 6 : Yawn To Test Your Helmet Fitting

Before you embark on the ride, attempt a big yawn, and see how the helmet reacts to it. The expectation is that it should pull downward. If not, tighten the chinstrap and try again. If the helmet moves backward more than two fingers, unbuckle and move the slider upwards to tighten it. If it is coming too much towards your eyes, move the slider downwards to loosen the helmet a bit.  

Some helmets have a fit system in them, which makes it easier to get a snug than those that only use pads. Use the fit system then buckle the straps after you get the right fit.
