              How To Choose The Best Commuter Bike Helmet?

              Size & Fit

              A bike helmet that fits your head will not only provide comfort but also compromise effectiveness in case of a crash. There are multiple choices for you to choose from, based on parameters:

              • Small size: 20-21.75 inches

              • Medium size: 21.75-23.25 inches

              • Large size: 23.25-24.75 inches

              • Extra-large size: over 24.75 inches

              • One size fits all: feature an adjustable system

              Visible Features

              When choosing a bike helmet, you should also consider several features:

              • Mount compatibility: this feature allows for snapping in the mount to hold a light or an action camera.

              • Full face protection: mountain bike helmets can come with a wraparound chin bar that better protects your face when you go downhill or race.

              • Visor: a sun-shielding visor often come with mountain bike helmets.

              MIPS

              Short for Multi-Directional Impact Protection System, this allows your head to rotate slightly inside the helmet instead of your brain spinning inside your skull. You should choose a bike helmet that offers MIPS because it will help soak up the rotational forces.

              Ventilation

              A bike helmet with good ventilation lets wind flow over your head, helping you stay cool and comfortable while riding. Also, the more ventilation, the lighter the helmet. You should definitely get a bike helmet with this function.

              FAQs

              How often should bike helmets be replaced?

              A quality bike helmet should last from 5 to 10 years, according to the Consumer Product Safety Commission.

              Are expensive bicycle helmets worth it?

              It appears that the effectiveness in protection is virtually identical between cheap bike helmets (under $20) and expensive ones (over $150).

              However, more expensive helmets will provide an easier fit, snazzier graphics, and more vents. So, if you are looking for protection only, you can opt for a cheap option worry-free.

              But if you want to look stylish too, maybe consider getting a more expensive helmet.

              Are MIPS helmets worth it?

              You should always get a bike helmet with MIPS since it provides extra safety for you when riding. Or you can upgrade your current helmet from non-MIPS to MIPS-equipped with just $20.

              Why do helmets expire?

              A bike helmet doesn’t have an expiration date. However, you should replace them every 5 years to ensure safety.

              Does dropping a helmet ruin it?

              Then answer is yes, if you drop your helmet multiple times on the ground or hard surfaces, that will degrade its performance and you may need to replace it.

              Conclusion

              A good helmet is very important when you ride a bike as it keeps you safe in case of an accident. That’s why you must be careful when picking a bike helmet for your future rides.
