BELL Sixer MIPS Adult Mountain Bike Helmet

Amazon box arrived in good condition, but helmet package inside was crumpled and missing the original outer box. Helmet was below retail probably because it was made last 12/2021. Anyway, package was complete with the light mount. I have a 59 circumference head and this fits with 5-6 clicks left in the Float Fit to tighten. Helmet profile is round and not bulky at the top like other helmets. I like the top most visor position as it can funnel more wind thru the vents. Build quality and graphics looks nice.

This helmet truly saved my noggin from an unexpected low tree branch, took a real knock that severely dented the outer shell and cracked one of the inner foam ribs in half, but the MIPS worked great and I came away with zero injury and just a bit stunned. So for actual performance as a head saving device, NO complaints, 5 stars :)On top of that, it's a very good looking item, and fits perfectly, without squishing my sunglasses against the bridge of my nose, which some other helmets do. I also really like the adjustable visor.Just two complaints (nothing's perfect I guess):1) the little yellow rubber retention do-dads that keep the MIPS membrane attached to the helmet itself are just too cheap, and don't last long, maybe 1 year or so (and of course, the warranty is 1 year....) It would sure be nice if they lasted longer, or at least could be replaced once broken, but Bell says they cannot be field replaced. I often kind of squeeze the helmet against my head to wring out the sweat when riding - in doing so, it seems to put too much stress on those do-dads, and eventually they will just break in half. Once that happens, the helmet is basically done. *Maybe* you could still use it with one of those busted, but with 2 or more busted, it's not usable, the thing just floats all over your head at that point. In any case, even with one busted, not sure if it would perform right from a safety standpoint... Not sure if this is Bell or just the MIPS design in general (same or similar retention do-dads seem to be used on other vendors).2) the plastic bolts holding the visor in place are awful. They are almost guaranteed to fall out within a week or two of riding, and you'll probably lose at least one that way and not be able to find it since the bolt will fall out at some point but the visor won't noticeably detach from the helmet on that side until the next big hit or whatever. I tried putting some loctite on to hold them in, but since they're plastic, that just solvent dissolved them and made them unusable. Now I basically just replace them with metal bolts and loctite as soon as a I open the box, having learned from the previous couple. YMMV. Happy riding!

This is the best helmet I've ever got, it's super comfortable, fits perfectly, and I love the color.

Nice looking helmet. Bell is a reputable manufacturer. MiPS. Adjustable visor. GoPro/light mount built in is cool. Sizing is way off. Runs small. I'm 56cm and the medium (55-59cm) barely fits with the adjustment all the way out.

I have found it hard to find a good helmet that has a reasonably robust adjustable visor. It's early days yet as I have only had the helmet for a very short period but "so far, so good!" The helmet fits well and I can attach the round version of Cateye flashing lights, one on the rear and one each on side using 1 inch Velcro straps for nighttime or use in rainy weather. The open lower vents enable the encirclement of the Velcro straps as a mounting. I find that the adjustable decent length visor is essential for safe riding particularly when riding at sunset or early in the morning. As someone once told me about the necessity of using a visor under such conditions, "It might save your life!" In summary, if I buy another helmet as a spare this one is currently my top pick.

The helmet is of good quality and craftsmanship. It fits and it fits me well, while being comfortable. I have a big head (7” 3/4) so it’s hard to find a helmet that’s not black. The helmet looks good and the GoPro mount is a plus! Very happy with the purchase. Will definitely buy from Bell again.

This helmet fits really well adjust down perfectly. I have a taller head and Bell helmets are always the best. They sit right on me like they do everybody else’s perfectly. The rear adjustment is dead on and it’s lightweight. I use it for my one wheel, but it’ll be great for a bike as well.

Very comfortable, ventilates well, almost don’t feel it on your head after a while. On par with my Fox branded helmet for comfort and adjustment.
