Bicycle Helmet Mirror for $2

Step 9 Finished assembly and use

Sandwich the aluminum squares around the wire frame and the mirror's swivel ball. Clamp with the screw. Use a toothed washer to keep the nut from working loose. Tighten the screw and nut enough that the mirror stays where you want it. Leave it also loose enough that you can adjust it while riding your bike. I find the mirror works well for me if I can just see a bit of my ear in it. That gives me a reference point for what I see in the mirror. It is not a problem if you adjust the mirror so that you need to incline your head just slightly to see the traffic lane fully. If necessary, you can tweak the bends in the wire frame to get the mirror roughly where you need it and then do the fine adjustments with the swivel features of the mirror and the aluminum squares.

I have been using one of these for quite a while and really like it.

Excellent instructable! I'd change step 8 to glue the screw into the one side and use a wingnut to hold it. Still very nice work!

Thank you. Your suggestion might work. The screw is not exactly perpendicular to either of the aluminum pieces. Accommodation for that would need to be considered.

smart but i dont wear a helmet

I did not, either, until I was almost 40 years old. I even had a couple of crashes that could easily have resulted in permanent brain injuries. A couple of years ago I had another crash that cracked the helmet above my ear in two places, but left me without so much as a headache. A crash resulting in a brain injury could easily leave a cyclist a vegetable for the rest of his life.
