Helmet specifications


  • What sizes does Lumos come in?
    Lumos comes in a one size fits most ADULT size similar to other helmets currently in the market. The helmet fits users with a head measurement of 54cm - 62cm / 21.3 - 24.4in. Here is a quick guide to how you can measure your size to make sure the helmet will fit well.
  • Does the helmet come in other than ADULT size?
    This being the first time we are bringing Lumos into the market, unfortunately we currently (for our first production run) dont have the ability to produce models beyond the ADULT size for now. However we are keeping another waitlist for people who require sizes smaller/larger than our ADULT size and we invite you to leave your email on that list so that we can contact you once we do make S & XL sizes available in the future. You can add your email to that list. Thank you so much for your interest and we hope to have a Lumos Helmet available in your size in the near future.
  • Is there a kids' size?
    We would like to create a Lumos model for kids in the near future, but at the moment have no immediate plans to do so. If there is sufficient interest and demand for it, we may accelerate our plans though! If this is something you’re interested in, let us know by filling this short survey.
  • Do you have a quickstart guide?


  • What colors does the helmet come in? 
    Lumos is available in three colors: Pearl White, Charcoal Black, and Cobalt Blue.


  • What is the battery life?
    Designed to fit the typical 30 - 45 minute urban bike commute, the battery lasts approximately 6 hours on flashing mode and 3 hours on solid mode.
  • How long does it take to charge?
    The helmet takes approximately 2 hours to charge.


  • How many LEDs are there?
    The Lumos Helmet features 10 super bright white LEDs in the front and 16 super bright red LEDs in the rear. There are an additional 16 bright orange LEDs for the turn signals. 
  • Will the lights be visible in the day?
    It depends. As with any other light, if it is broad daylight with direct sunlight, the lights will not be very visible. The darker it is, the more prominent the lights will be.
    For the turn signals, you should always use hand signals and only use Lumos as a supplement to those, even at night. During the day this is especially true as your hand signals are readily visible.


  • How much does the helmet weigh?
    Approximately 440g.


  • What type of certification does the helmet have?
    Lumos meets the following bicycle helmet safety standards:
    - CPSC in the United States (CPSC 16 CFR Part 1203)
    - EN1078 in Europe Lumos also meets all other requisite standards required of consumer electronic devices set by the FCC and CE.

TROUBLESHOOTING ("My helmet doesn't work!")

  • My helmet does not respond to my remote! / I am unable to change flashing modes!  / I have to pair with my remote each time I turn on the helmet!

    You might be accidentally entering "pairing mode" on the helmet when you turn it on. Easy fix!

    When you turn your helmet on, just tap it rather than holding it (i.e. a short press, not a long press). This should solve the problem.

  • Does it come with a visor?
    Our current model does not offer a visor.
  • Is it fitted with MIPS?
  • Is there an app?
    Yes! There is a Lumos Helmet companion app that you can download on iPhone and Android devices. With the Lumos app you can configure settings on your Lumos Helmet, monitor battery life of the helmet and remote, and update the firmware of your helmet as updates become available. Download the iPhone app here, and the Android app here
  • Are cables and remotes included?
    One remote is included with the helmet, as well as a remote mount and charging cable. 

Placing an order


  • Can I change my shipping address after I have placed an order?
    Orders usually get shipped out from our warehouse either the same day or the next day. Unfortunately it is not possible for us to edit the shipping details once the helmet has been sent out. 
  • Can I change my color choice after I have placed an order?
    Similarly with address changes, because we send orders to our warehouse in real time to be shipped out as quickly as possible, orders usually get shipped out either the same day the order was placed, or the next day. Unfortunately it is not possible for us to edit the order details once the helmet has been sent out.
