5.0 out of 5 stars This helmet is no joke.
By ZAOT on July 26, 2021
Update: This helmet is surprisingly cold in sub 50 degree weather. Something about the shape seems to funnel the wind into your ears and eyes. There is no way to add a face shield . There is also no spot to attach a goggle strap. A balaclava does help a bit. This is still a great helmet, but the lack of a face shield is something to consider if you ride in a colder climate.

I recently purchased an ebike for a 24+ mile a day commute. I felt that my Giro Fixture helmet would not protect my head at faster speeds ( see the difference between the Tyrant (Left) and Fixture (Right). Cue the new helmet search. I tried the Bell Super Air MIPS and felt it was to bulky and heavy. My other consideration was the Fox Dropframe mountain bike helmet. The key things that kept me from purchasing the Fox Helmet were lack of adjustability and MIPS technology. I also could not find it in the color/size I wanted. I have a head circumference of 53cm and ordered the small Tyrant helmet. Upon trying the helmet on, it feel a little tight and heavy at first. Do not let this deter you from the purchase, the clicker on the back is adjustable and pads conformed to my head shape quickly. When standing still while wearing the helmet it does seem HOT. However, once you are moving on a bike, the vents do their job and keep the head very cool. I rode 12 miles in 95 degree heat today with zero discomfort. The most important thing is that this helmet feels SAFE. It hugs the head in the all the right places, without becoming uncomfortable. I honestly think this helmet is the best protection you can find without wearing a full face/motorcycle style.
