How to Put a Bumper Sticker on Your Bicycle

• Sticker
• Plastic sheet
• Scissors
• Hole Punch
• Zip Ties (2-4)
• 30 minutes of time

Causes

There are so very many.

Apparently bumper stickers are going out of style. I hope bumpers and the cars they are attached to go out of style. It would make my bike commute much safer.

My bumper sticker came in the mail after I phone banked for the Bernie Sanders campaign. Be kind, conservative commenters. I'd hate to have your hard-written words deleted by our moderate moderators. Interestingly, it was printed by union stickersmiths of Local 820 Sign Painters Union. They didn't seem to consider the bicycle.

Plastics

There are so very many.

I found a sheet of white polystyrene. It is robust, flexible, white, and cheap. They sell it at arts and crafts stores.
Other options would be

• Coroplast/Corrugated Plastic (old political yard signs)
• Plastic sheet from craft store
• A milk jug (PET)
• Cardboard, but only if you live in Los Angeles or another desert
• Metal if you are hard core and like to get cut
• a wooden 2x4 plank and a u bolt

I used a transit card to smooth out bubbles.

• Mark the center of the sticker. You want it to be balanced.
• Offset some lines on either side of the center
• Be sure to round any internal corners. This will make it less likely to rip at the corners when you kick it as you get on/off your bike!

I used regular scissors. I needed both hands, and couldn't take a photo. Imagine it for me: A sharp pair of orange righty Fiskars easily, safely, and accurately slicing up the plastic.

You can use a 3-hole punch, a regular punch, or a leather punch.

You could also carefully cut holes with a Xacto knife, or burn the holes with a magnifying glass on a sunny day, or heat up a rod and press it through. A drill would be tricky, I'd recommend a board on the front and back to prevent a tear up.

I wanted it to bounce as I rode, so I put a bend it it so it would sit proud off the tail of the bike.

Using zip ties, attach the sign to your seat.

I used two, but I wish I used 4.

Two on each post would make it much more stable.

Be sure to bike kindly, or folks will associate your cause with reckless riding.

Or, ride recklessly with the sticker of a cause you don't support! That's called a false-flag, or in this case, a false-sticker.

The CarBike of Pittsburgh offers plenty of sticker space and make sure cars give you the space you need.

I miss Pittsburgh. When I biked in Pittsburgh, I'd see him all the time. Cars gave him way more space than they gave me.
