The following submission comes from reader Atom Smasher.
If I were king, all bicycles would have bells or horns. Until then, I have to be the change I want to see in the world, and teach my four-year-old to not sneak up on people with his scooter (or bicycle).The friendly LBS has a bin full of freebie bike-bells, and I needed to replace the broken bell on his scooter. But this bell was made for mounting to handlebars much smaller than the scooter.
Just remove the bolt and slide out the square nut, then lace it up with a zip-tie. Pull it tight. Done!
There's also a small piece of inner-tube to keep the whole thing from rotating. That hack was learned on the old bell, which had to be adjusted almost every day.
