Here's what others have to say...


Great fit and style

  • Familiarity:I've used it once or twice and have initial impressions

I'm a petite female and the S/M fits great -- very adjustable, so I'd be surprised if you couldn't find the fit for you. I love how reflective it is for city/night riders. And the visor is removable, which is nice if you want to go a little more sleek one day. Very happy with this helmet.


Great Helmet

  • Familiarity:I've used it several times

I bought this helmet for my wife and another similar Bell helmet for myself recently and they are perfect. Hopefully we never have to see how well they work in a crash situation? However, they fit great with adjustments and provide ventilation and comfort. I'm happy with the price as well.

Unanswered Question

Does this helmet use the OneStep plus fit...

Does this helmet use the OneStep plus fit or TAG adjustment system? The description says OneStep plus and specs say TAG.


muni helmet

  • Familiarity:I returned this product before using it

This was a great helmet, but the s/m was slightly bulky for my head 20.5" . Quality and features for the price were great though. I returned it because the Giro Amare fit more snugly and was lighter weight also a bit more stylish than the Bell.


Did the trick!

  • Familiarity:I've used it several times

Got this for my girl(whom has a smaller than average head diameter) and it fit! She has about a 20.5" diameter head and the S/M fit perfectly! Other than that the price was right on and she uses it for both commuter and mountain. Visor could be a little bigger but can't get everything for this price.


Great Verstile Helmet

    After wearing rounded skate-style helmets for years, I am venturing back into vented helmets. What I wanted is a vented helmet that doesn't take itself too seriously, that doesn't have the crazy racing point at the back, that looks halfway stylish. And, so far, I'm beyond thrilled with this Bell helmet. The fit is a little strange and not as adjustable as I would like, but I like the way it sits on my head and I like the fact that it has a rounded back. The two little led lights at the back and built-in mounts for additional lights is awesome for commuting around the city at night.
