Since i've had some trouble with other bikers while I ride my bike on the "Ciclovia" and on the "Ciclorutas" Cycle Ways in my city (Bogota, Colombia), because I wasn't able to see them behind or by my side, I had the need to get a couple of mirrors for my bike. I looked them up all over the city and on the net but what I found where too big, too long or too expensive and since I didn't want the "anthens" look on my bike, I decided to build my own and install them myself.
This is my first instructable, I hope you find it useful. :)

## Step 1: Find Materials

I had a couple of Rotating 360 adhesive wide angle small mirrors that I bought for my previous car, that I thought I could use for my bike. Then I had to find some material to create the mount for the mirror, so I found an old piece of Zinc sheet (that is used for roofs in popular neighborhoods in Colombia) in my home tools shop that I could cut and bend in a round shape to create a mount for the mirrors and stick it with double sided tape to the steering bar of my bike. I suggest to use a soft metal sheet that can be bent, it can be cooper, alluminum, etc.

## Step 2: Measure Bar and Mirror

With a measuring tape, measure the contour of the bar and the diameter of the back side of the mirror to calculate the length of the stripe you'll need. (Bar contour + (2 x mirror back diameter) = length of the stripe)

## Step 3: Draw and Cut

Whit a ruler, draw the stripe on the metal sheet (zinc in my case) and cut it. (2 pieces)

## Step 4: Bend and Form the Mounts

With the help of the handle bar, bend the stripes and comform the mounts. Then test them to check if they fit properly. Feel free to unbend and rebend if they don't fit or even cut...

## Step 5: Add Double Sided Tape

Cut a couple of pieces of double sided tape, long enough to cover all the shape of the mount. Then cut the excess of tape until neat.

## Step 6: Mount the Mounts

Sitck the mounts to the steering bar. Make sure they are positioned on the desired angle for the mirrors to work.

Stick the mirrors on the mounts. Make sure they are possitioned on the right spot, it means on the middle of each mount and on the middle of the mirror tape.

Sad that you need them, but good design. Have you had any issues with sharp edges on the metal strips?

hello! well, no. Since i know about the edges i am very careful. the real issue is the tape i employed, i had to replace it because the strip unglued. thanks for comment. bye!

Would a tube of rubber cement work better for holding things steady? Takes a few hours to dry but fairly solid after that.

that's a great idea! however, if you want to take them of, it would be kinda difficult, for example, if you want to return the bike to its original conditions or if you find better mirrors and want to replace them. thanks for your ideas! bye

Good point. I was thinking more about holding the mirrors to the metal, but yeah gluing them to the bike could be a problem. Glad you found a tape that works well.

what i did is to find a better brand of tape, i.e. scotch or tesa, and it work fairly fine

This is a great build. It's not enough to just be aware of automobiles, we need to be aware of pedestrians and other cyclists too. Thank you for sharing your project.
