These lug nut covers are 21mm and will fit over the top of most larger scooters' wheel lug nuts. Most of the stock caps fall off pretty quick, on every scooter. It's something that you don't realize until it's already happened to you. These fit on snug, but can still fall off! But, a dab of silicone on the inside of these covers, slide the lug nut cover over your 21mm tire bolt, and your threads stay protected while keeping your ride looking fresh. Usually we find 21mm bolts on larger size electric scooters, but some e-bikes have them, too! Make sure to measure yours before you buy please. These are available in Gold, Silver, Black and Blue. The Gold looks great along with a pair of our 160mm brake rotors, aluminum, or even titanium disc brake screws. Usually you need to pay $14 to get a pack, and they come with way more than you need. We sell these covers in packs of 5 so you'll have just enough, plus one spare.
