Dirt cheap DIY Smartphone Bike Mount

I use my bike quite a lot to commute in the city.

And, sometimes, to find the good street (believe me, in France, it’s not that easy) with the GPS while riding is tricky.

So I’ve been looking on the Internet to find THE good smartphone holder: unfortunately they are either bulky or expensive (and most of the time both)

Except this one: the Finn, a $9.95 silicone mount:

But buying things is not the hacker’s way.

So let’s take the design on Inkscape:

Download the pdf file here and print it on a A4 paper sheet without scaling.

Tape it with carpet double side tape on an old bike tube.

Cut the tube by cutting the paper pattern at the same time and remove the paper and tape.

Rub’it on your bike and let’s ride!

Important: the mount has to go on the back of the handle bar, as shown on the step 3.

  1. Very nice.
    I changed a little thing. To have a smoother cut I rounded the edges more. My first try was having tears after a few seconds of tension.
    Thank you

  2. I’m wondering if you are riding on a bumpy road like in the forest or countryside, would you risk the phone just popping out and smashing on the floor? I thought of also having it attached to the bike with some kind of string, maybe..

  3. Thank you so much!
    This is the quickest, cheapest most DIY solution I could find and it seems to work, too 😉
    Will take it for a test ride soon.

  4. great
    try using a hole punch for corners & centers of lines & join holes with straight clean cuts to prevent Jagged or rough cuts as these will tear out or become the weak spot/s,
    Replace when rubber come off as powder to touch which will happen (eventually) from UV exposure, it should last several months at least in direct Sunlight, just remember to check when mounting phone,
    Use TWO for added security/stability

    love reusing inner tubes , thank you.

  5. Indeed, this work and hold the phone on the handlebar even on bumpy roads. The only thing it does not and that needs some more thought is that a) it is not easy once the phone is attached to rotate it around the handlebar to adjust the angle to seen it perfectly (you need to loosen one end from the phone, inch it into new position and fasten again – repeat until it sits where you want it) and b) unless this is a really smooth road newly tarmacked, the phone wiggles around handlebar quite madly (does not fall out tough) so that you can’t see a lot.
    That’s why the commercial version has this mini-platform.

  6. That’s awesome! Reusing the bike tires and saving money on phone holders..what a great idea! Thanks!
