Helmets are always a good idea when riding any type of bike, and some states require them. Pennsylvania, Massachusetts, and Oregon are some of the states that require wearing a helmet when riding an e-Bike, though most states don’t have a legal requirement.
MIPS Helmets: What’s The Tech and Is It Worth It?

Helmets save lives, and we know that for sure. But there’s a bit more discussion about MIPS technology and the extent of the impact-protection benefits it provides.

I’m a big nerd when it comes to bicycle safety. I won’t say that you need to experience a crash to become a “true” cyclist— that is ridiculous gatekeeping— but you surely become a wiser one after suffering a fall or traffic incident. I’ve been in a couple of collisions myself (stories for another day), and my helmet was one of the reasons I was able to walk away relatively unscathed.
Riding safety isn’t only about wearing a helmet, but helmets are a crucial ingredient— we’re talking must-have e-Bike accessories here. I probably don’t need to remind you, but please always wear your helmet. In the pursuit of ultimate head protection, many modern bike helmets come with a MIPS layer. In this article, I’ll explain how this thin layer of plastic can reduce the risk of brain injury and whether the science really checks out.

What is MIPS?
MIPS technology can usually be recognized by its characteristic yellow webbing inside a bicycle helmet. It stands for Multi-Directional Impact Protection System and was designed to help redirect rotational motion away from the head in the event of an impact.
The low-friction layer can move slightly during an impact, potentially lowering the rotational forces that can worsen a brain injury. The MIPS protection helmet liner is essentially a thin plastic floating shell that sits close to the head on the inside of the helmet construction. Helmets equipped with MIPS will have a MIPS yellow dot sticker, and while the inner layer isn’t always yellow, it’s pretty easy to spot in the interior of the helmet.
How does MIPS work?
The advantage of the MIPS system revolves around the low-friction layer’s ability to move slightly inside the helmet. This slight sliding effect helps redirect forces away from the head and reduce the rotational movement of certain impacts. Really severe concussions, brain damage, and head injuries happen, in part, due to rotational motion— basically, when your head gets hit but your brain continues to move or rotate inside your skull in response to the impact. The fact that the MIPS layer can slide between 10 to 15 millimetres may help distribute and reduce those impact forces.
Riders wear a MIPS helmet just like any other bicycle helmet. Like normal, there’s a chin strap, helmet padding, and ventilation channels. You may feel the layer when wearing the helmet, but helmet brands adapt the lids to achieve the proper fit and size with MIPS. Most helmets have a micro-adjustable dial to achieve a snug, well-fitting bike helmet.
How much do MIPS helmets cost?
When MIPS was first introduced, the added layer came at a premium for bicycle helmets, increasing the retail price. Nowadays, there are many affordable MIPS-equipped helmets, and the cost difference between MIPS and non-MIPS helmets of the same model has decreased— it’s typically around $40.
In general, MIPS increases the price of a helmet, but there may be some bias since many helmets with MIPS are high-end models that would cost much more than a standard helmet anyway (due to features like ventilation ports, aerodynamic helmets, and weight). But there are outlier helmet manufacturers like Kask that choose to produce pro-tier helmets without MIPS technology. In Kask’s case, its helmets are tested according to the WG11 standard to measure the rotational friction of the inside of the lightweight helmet.
Are MIPS bike helmets worth it?
The sticking point when it comes to confirming or debunking the effects of MIPS is that there is currently no recognized standard to test for the reduction of rotational forces transferred to the brain. This prevents us from really knowing just how much of an impact MIPS has in reducing rotational forces and preventing severe brain injuries. Some engineers have called MIPS a bit of a marketing gimmick or claimed that having hair on your head provides a similar amount of slippage inside the helmet to reduce rotational forces.
But the most widely held opinion is that you probably shouldn’t skimp on head protection, and spending a bit more cash is a good idea, even if it only provides slight helmet benefits. And I agree with this. I’m inclined to think that extra peace of mind and potential protection boost is worth it. It’s an even better idea for electric bike users who travel at higher speeds or ride close to cars in traffic.
At the end of the day, though, most of the work is done for you already. All helmets sold in the US have to meet the strict CPSC standard that ensures the helmet offers high-quality protection. Instead of worrying as much about MIPS, the more important choice is buying from a reputable brand that makes a product you will love to wear all the time, whether that’s because of comfort or performance reasons. And make sure the helmet fits you properly— a wrong helmet angle or an ill-fitting helmet provides significantly less protection.

What are the safest bike helmets?
The Virginia Tech Helmet Lab is well-known for its rigorous helmet tests and STAR evaluation system. Each year, they update their exhaustive bicycle helmet ratings based on their data, offering riders objective results on where to find the safest bicycle helmets. Some top-rated helmets have a MIPS safety system, and some don’t, and these lab results are my preferred source of helmet safety properties. The highest score is a 5-STAR Virginia Tech safety rating.
Upway sells a large variety of e-Bike accessories, including MIPS-equipped road helmets with airflow ventilation and mountain-bike helmets with a removable visor. There’s a model for all types of riding, from commuter e-Bikes to lightweight road bikes. We specialize in getting you the best deal on a new or used electric bike from the top brands!
Frequently Asked Questions
Are helmets required when riding an e-Bike?
What does MIPS in a bike helmet actually do?
MIPS (Multi-Directional Impact Protection System) is a thin, low-friction layer inside the helmet that allows it to move slightly during an impact. This movement may help reduce rotational forces on the brain, which are linked to concussions and other head injuries.
Key Takeways
- MIPS May Reduce Brain Injury Risk: MIPS technology helps redirect rotational forces during impacts, though its exact effectiveness lacks a universal testing standard.
- MIPS Helmets Are More Affordable Now: The price gap between MIPS and non-MIPS helmets has narrowed, with some high-end brands opting for other safety standards.
- Fit and Certification Matter Most: All helmets must meet CPSC safety standards; a well-fitting, reputable helmet is key for protection, with Virginia Tech providing trusted safety ratings.
