MTB Helmet Under $100 Buyer’s Guide

Now that you know which MTB helmets under $100 are considered the best around, you might still have a few questions to help you choose which one. Sure, it’s nice to clear off the thousands of options to consider, but ten is still quite a few. To help you along in choosing which mountain bike helmet under $100 is right for you, we’ve made a little buyer’s guide.

Do you need a full face mask to go mountain biking?

Do you really need to have a full face mask if you want to go mountain biking? Some say yes, while others say no. The truth is that it’s fully up to you. If you’re going in rough terrains with ramps or steep declines, then we’d definitely say that a full face mask is a good idea. You should always protect your head at all times, especially in risky situations.

However, if you’re simply cruising through light hills or dirt paths, then you’ll probably be fine with just a typical MTB helmet under $100. Always try to find one with a visor though, as they help keep the sun out of your eyes. Also, any helmet you choose needs to be adjustable. After all, there’s no such thing as a ‘one size fits all’ cycling helmet! Being able to adjust it all allows you to customize the helmet exactly as you need it without sacrificing any extra safety measures.

When and where do you go mountain biking?

Knowing when and where you bring your mountain bike will tell you a number of things. For starters, it lets you know if you need a visor or not. While we definitely said it’s always a good idea to have a visor, not all helmets are created equally. If you find yourself cycling in an area that isn’t too sunny, then you might not need one. However, it’s still always a good option to have for ‘in case’ scenarios.

Another reason why you should know when and where you’re riding is that you’ll probably need a taillight if you’re going at night. Regardless of where you are, you should always be illuminated when it’s dark outside. This’ll protect both you and the people, cars, or animals you come across.

All in all, choosing a new MTB helmet under $100 should be a fun process. Now that you know what you need to know, which one did you choose?
