Planet Bike BRT Strap

I met a friend for coffee the other day and his trowser cuff strap caught my eye. Even in broad daylight it was surprisingly bright with its flashing LED. I asked him about it, and it turns out it was a BRT Strap from Planet Bike. It gets a 200 hour run time on a CR 2032 battery and has flashing and steady modes. I don’t have one yet, but I’m planning on ordering one for when I ride my bikes that don’t have chainguards. I figure if I need a cuff strap anyway, it might as well have a bright light in it!

    I have been using one of these for the past 2 years, but I wear it on my upper arm to be more visible to cars from the front and side.

    You can see it here in my last ride before the snowpocallypse:

    I use one of these as well. I find the reflective properties quite worthwhile as well. I was worried that if the batteries died, it’d be nothing more than a cuff strap, but it’s very reflective.

    My wife rides with this on her upper arm as well. She loves how bright it is. The strap has held up quite well after a year of use.

    I, too, have one of these, which I wear on my left arm and which I got from Planet Bike (Disclosure: Planet Bike is not a sponsor of this commenter… they just have cool stuff).

    I have the equivalent item from MEC. The battery died a while back, but I’ve found another use for it. I have it on the back of my xtracycle, and I ziptied a Planet Bike superflash taillight to it. One of the issues that I’ve had with putting a taillight on the Xtracycle is that when I mount it rigidly to the back, because it sticks out so far, it can get banged around or things hit it during loading and unloading, and I’ve broken one light this way. If the light is on a flexible strap, then it can be banged with no harm done.

    The setup is somewhat visible in this photo:

    I refuse to use any battery-powered light that won’t take rechargeable batteries.

  • Alan says:


    I hear ya’. I’d love to see a solar powered version.

  • DerrickP says:

    These are great. I’ve often used them in a pinch when I’ve had an awkward item that needed to be strapped to the rack (if it doesn’t fit in a bag). I also use them on my arms when my panniers would block my ankles.

  • Pamela says:

    Hmmm…how about having one of these on each wrist, to signal left/right turns or lane changes in traffic? Kind of like Glo-Gloves with a flasher.

    Another use: A dog collar on evening walks. Very effective!

    Hey, buddy, thanks for getting me busted! After reading this tonight, Mrs. BRT Strap gave me “that look” and reminded me I need to return it! Lol!

  • john in nh says:

    yeah I like it but for the lack of rechargeable battery bit however while this would not be pretty, with a bit of work you could hook up a small voltage regulator and hook up a pack of rechargeables maybe strapped to the arm or leg instead… but again this requires some work and modifications, however even without the battery it looks great!

  • Dwainedibbly says:

    I’m glad I’m not the only one with that concern.

    A single AAA rechargeable isn’t that big. Come on, PlanetBike, I expect more from you! (If I recall, PB showed another product in the past year or or so that used coin-cell batteries.)

  • ken says:

    I don’t understand why PB can come up with something like this but can’t make a tail light that mounts on a rear fender.
