Time has come to finally end my summer blogging hiatus as the fall winds sweep in. A lot has happened over the last two months in and outside of graduate school — from my very first first-author publication to countless cycling adventures (photo above being from the latest ride northwest of Calgary). While it’s sad to see summer wind down, I’m excited to embrace the beginning of the fall and the challenges it will offer. It’s time to ride into the storm.
Do they matter?
The answer is an overwhelming yes.
Here are just a few numbers from a meta-analysis (i.e., a summary of all existing quantitative research) by Oliver & Creighton (2017) assessing the effectiveness of bicycle helmets in crashes and falls:
51% less likely to experience a head injury
69% less likely to experience a serious head injury
33% less likely to experience a facial injury
And 65% less likely to experience a fatal injury
To boot, other meta-analyses find relatively similar results (Attewell et al., 2001; Elvik, 2011; Høye, 2018).
So yes, bicycle helmets matter.
But recent innovations in bicycle helmet tech have improved their effectiveness a considerable amount.
Here I’m talking about WAVECEL and MIPS (Multi-Directional Impact Protection System).
While these two helmet technologies work in slightly different ways, they essentially soften the impact on the head by separating the helmet and your head from the initial shock.
With a traditional helmet, there is essentially a plastic and foam barrier between your head and what it hits, but your head rotates with the helmet at the same speed (and it’s this initial rotation and acceleration that leads to most head injuries, such as concussions and traumatic brain injuries).
With MIPS and WAVECEL, there is within the helmet a moving liner or collapsible structure, respectively, that decreases this rotation, and ultimately the chance of head injuries (Bliven et al., 2019).
So if you’re in the market for a helmet, I would highly recommend looking out for either MIPS or WAVECEL, with MIPS helmets tending to come in at slightly lower costs because the tech has been around for quite a bit longer.
If you’d like more information about bicycle helmet testing, check out the website for Virginia Tech’s helmet testing lab. They run comprehensive third-party testing on helmets for various sports, including cycling.

This summer I wanted to find the cycling path to and visit Chestermere, as well as visit and ride through Fish Creek provinicial park in southern Calgary. I never thought I’d do this in a single ride, but that’s what ends up happening when you get slightly lost. Besides, it’s never really getting lost or going in the wrong direction when you’re on a bike, it’s called exploration. Kudos to my buddy Kevin for the company and hammering through. Ride on.
Had the wonderful opportunity to ride out in Kananaskis Country on a highway that is closed to cars for half of the year (how awesome is that?!). Apparently Highwood Pass is the highest paved road in Canada at 2206 meters. Definitely one of my favourite rides so far. Shout out to my buddy Vaarun for letting me know about this and inviting me out. Ride on!
Had the opportunity (and legs) to make it to one of my favourite cycling destinations within range from Calgary: Bragg Creek. Legs were feeling good today and managed to power through despite a nasty headwind on the way there (convincing myself how so very sweet it would be on the way back helped!). Ride on!
I had to go to Edworthy Park for my first outdoor ride on the Roubaix this year. One of my favourite small twisty climbs within Calgary. What goes up — is all the more fun going down. Ride on.
