Here's an old thread that I still post to. It allows you to print a vinyl bumper sticker decal with typical bicycle logos. The bumper stickers hold up pretty well and are not that expensive. The images I post are my own work. Some of them are not that good quality and often the font is not an exact match. I am getting better at it and now post .svg or .pdf images for better resolution. Feel free to down load the images and post them to a bumper sticker online printing service. As long as you are printing the images individually for your individual use on your bicycle it is nothing more than a bumper sticker...
