From the brand

-
Lumos began on the streets of Boston.
It’s where we first fell in love with cycling as a way to get around. Except that it always felt like we were putting our lives in someone else’s hands every time we went on the road. We always felt that people (drivers especially) didn’t see us, especially at night. We created Lumos because we were trying to solve a problem that we were experiencing in our own life.

- Reviewed in the United States on May 25, 2025Color: Charcoal Black with MIPSSize: XL (24"-25-1/2" / 61 to 65cm)Verified PurchaseOutstanding helmet. Would have given 4 stars because instructions were ~ none; no transformer with the charging cable; on/off switch difficult; the Red version sadly not available, but still a great helmet. MIPS I believe is worth the extra and the light weight and fit are great, the lights are bright and the turn signals amazing. Good value for the money.
Mo. later update: Minor problem: 1. with a recumbent, bumpy ride, the rear Mips inner part knocks loudly against the outer, need some adhesive foam tape. Lumos agrees. 2. The rubber charging cover difficult to lift, better after ~20 uses.
Some might need a small visor.

I landed on my right side and hit my head, shoulder,elbow and knee, The force broke four ribs,but I have no head injury. The helmet did its job.

And a big plus is that it comes with a turn signal that activate the rear helmet lights. The only problem is that the description wasn't clear that it doesn't include a visor. Which must be ordered separately and at present the visor option is out of stock.

5.0 out of 5 stars Lightweight, well-fitting with stylish lighting.
Color: Charcoal Black with MIPSSize: M-L (21-1/4” to 24” / 54 to 61cm)Verified PurchaseThe Lumos Ultra helmet is available at 2 prices. The lower price is WITHOUT MIPS. The higher-priced helmet is WITH MIPS. I opted for the slightly more expensive with the additional protection, which is described as reducing helmet movement and helping to reduce brain movement and subsequent injury in the event of an accident. The additional protective material is inserted inside the helmet and you have to apply this yourself when the helmet is first set up to be used. It's easy and small patches of velcro keep it in place.
The helmet itself is lightweight, not too bulky and easy to adjust. The lighting on the helmet at the front does the job of helping increase your visibility and can be set to remain on, or flash. I would say the light is not bright enough to replace a handlebar-mounted light if the thought crossed your mind. The control for the helmet light flashing pattern can be controlled via an app, available for iOS and Android. There is a charging port and button to operate the light on the rear of the helmet.
The rear lights look great - very neat and bright, again, increasing visibility on the road. The rear lights also operate as indicator lights, left and right flashing. These are controlled via a supplied add-on for handlebars and are easy to use, with a small beep emitted from the helmet to let you know they are in use. Very handy. The button controller is small and easily attached to the handlebar. As with the front lights, the rear lights have customisation options via the phone app. The left/right indicator control comes with a 2032 battery and is easy to fit.
The phone app also provides you with feedback on the batter level of the helmet lights and Lumos actually offers firmware updates via the app, which is connected by Bluetooth to the helmet. The supplied USB-A to USB-C cable will charge the helmet from your typical iPhone or Android charging plug.
FYI - There is an optional device, compatible with this helmet, which can be purchased and I think uses an accelerometer to provide 'brake' lighting, to alert anyone behind you that you are slowing down.
The helmet is breathable and feels sturdy, offering a level of comfort and reassurance when you're cycling. It's good value for money in my opinion, and hopefully, I will never have to find out just how good the helmet protection can be.

5.0 out of 5 stars 車からの視認性が明らかに良くなりました
Color: Deep Blue without MIPSSize: M-L (21-1/4” to 24” / 54 to 61cm)Verified Purchaseフィット感 - アジアンフィットが60cmからとの事でMIPSもないこの商品を選ばざるを得ませんでした
実際装着すると他のレビューにもある通り側頭部がやや狭いですが痛さは無いです
機能 - 実は期待していた自動ブレーキランプ機能のために別売りのRemoteが必要なのに買い忘れてしまい、こちらは後日購入予定。
AppleWatchとの連動も手持ちのシリーズ3ではWatchOS9以上が必要との事で非対応で試せず
視認性 - 交差点や店舗の侵入時の対向車が認識してくれているようで
無茶な右折で進路を塞がれる事が大幅に減りました
