Not all helmets protect you the same way. MIPS bike helmet (Multi-directional Impact Protection System) was developed by a brain surgeon and a biomechanics researcher to address a type of crash force that standard foam shells weren't originally designed for: rotational impact.

Here's what MIPS actually does, how it works, who benefits most from it, and whether it's worth looking for on your next helmet.

is a thin, low-friction layer built into the inside of a helmet. It lets the helmet shift slightly against your head on impact, redirecting some of the rotational force away from your brain instead of transferring all of it directly.

Most crashes aren't clean, straight-on hits — they involve twisting, sliding, or hitting at an angle. Standard helmets handle direct impact reasonably well, but a rigid shell alone does less to manage the twisting force that comes with an angled fall.

MIPS bike helmet, addresses this with a low-friction liner that allows about 10–15mm of movement during impact. That small amount of give is enough to absorb part of the rotational energy before it reaches your head — similar in principle to how a car's crumple zone reduces force transferred to passengers.

The research backs this up. A study in the Journal of Biomechanical Engineering found MIPS bike helmet can reduce rotational acceleration by up to 34% in testing ( Zhang et al., 2014). Separately, the National Highway Traffic Safety Administration has noted that cycling carries one of the higher head-injury risks among common sports ( NHTSA, 2021), which is part of why rotational protection has become a bigger focus for helmet design generally, not just for UNIT 1.

No — MIPS is the most widely used rotational-protection system, but not the only one. WaveCel and SPIN are two other systems built around the same basic idea: managing angled impact, not just direct hits.

Each uses a different mechanism to do it, and independent lab testing (like Virginia Tech's helmet ratings) is generally the best way to compare how different systems actually perform, rather than relying on brand claims alone. If you're comparing helmets across brands, checking the Virginia Tech STAR rating alongside whatever rotational system is used will tell you more than the technology name by itself.

For most riders, yes — particularly if you're commuting regularly or riding in traffic where falls at odd angles are more likely.

Pairing MIPS with smart features gives you a helmet that covers both crash protection and everyday visibility: integrated lights you can customize, turn signals and brake lights so drivers know what you're about to do, and the rotational protection MIPS adds on top.

UNIT 1's FARO, NEON, and AURA all combine MIPS with this kind of everyday tech, built for city and e-bike riding specifically. For a closer look at how smart helmets compare to standard ones more broadly, see our Smart Helmet vs Regular Bike Helmet guide.

Your brain is priceless, and protecting it should be a top priority. MIPS helmets don’t just add protection—they redefine safety for modern riders. By reducing rotational forces, they significantly lower the risk of brain injuries, making every ride a safer experience.

If you’re serious about cycling safety, investing in a MIPS helmet is more than just a smart decision—it’s an investment in your well-being. And when you pair MIPS with smart helmet technology, like the UNIT 1 FARO, NEON, and AURA, you get next-level protection, visibility, and innovation designed for the demands of urban riding.

Don’t settle for outdated protection—upgrade your helmet, ride with confidence, and safeguard what matters most: your brain.
