Battery-free, frictionless bike lights.

If only I could have back all of those days I wasted, dreaming up better ways to route wires through a frame to a rear light, from the generator in my front hub. But how was I to know everyone in Denmark had these.

I rode around Copenhagen for nigh on a week, wondering why every long legged blonde I was stalking, had her flashing lights on, even at day time. At first I thought beauty had been harnessed as an energy source, but alas, they run on plain old fashioned magic, and work even for me. I bought a pair of reelights for around $60 Australian, fitted them to my Brompton in less than 10 minutes, and will never have to think about lights or batteries again when I get on that bike. When I fold the bike, they tuck away fairly snugly as well. The sheer elegance of the solution has provided days of aesthetic rapture, almost enough to compensate for those dark years of my ignorance.

    Security of these lights?

    I have only one question, as they look fantastic, too good to be true! Are they easily stolen from the bike? (I do not ask this with the intent of stealing yours of course, simply as a potential purchaser …)

      They fix the axle, under the nut, so are not likely to be stolen unless you have quick release skewers, which in any case are a pain on around-town bikes — all that triple locking and chaining! Let me know if you can find them online or in bike stores. I might want some more, perhaps with my next order from chainreaction.

        But dude; what if you get a flat while pootling over to the library? If you don’t have quick release wheels how is your team mechanic going to give you fastest possible wheel change and get you back up to the peleton with the least amount of chasing?

          Dr. Behooving chooses tough tires for all his non-performance bikes, with Dr. Sludge in the tubes, so rarely punctures. Oh, and it is nigh impossible to remove a rear wheel from a traditional dutch bike in any case, so I have learned to patch tubes without removing the wheel. It’s a big world out there. Take my hand and I’ll show it to you.

    My name is David and I’m from Barcelona, Spain. OI recently purchased a Brompton and I’m interested in installing a Reelight lighting set to the bike (I used them on my previous bike and I loved them). Before purchasing the lights, though, I wanted to know if it’s possible to install them without compromising Brompton’s folding…. After some research, I only encountered your post, where both lights are properly installed, but I still don’t know if the bike can be properly folded. I’ve been taking some measures and I’m completely lost!
    What’s your experience in this? Can these lights be easily mounted? Can you share a post and some pictures describing the process? Any help will be much appreciated!
    Thanks for your time.

      you just put them on, as you would with any kind of bike. They don’t interfere with the folding at all.

    • David says:

      OK, then. I’ll give it a shot! I just realized you installed the front light on the left side of the bike… I was trying to fit it on the other side, which wouldn’t have worked because of the handlebar.
      Anyway, if you still have the bike and the lights mounted on, I’d really appreciate if you could send me a couple of pictures showing how everything fits when the bike’s folded.
      Wonderful blog, Steven!
