3 Problems These Caps Solve Instantly:
-
Don't Let Chain Grease Ruin Another Outfit
Nothing ruins a ride faster than grease on your jeans. These caps keep your chain covered and your look clean, so you can ride out without the mess.
-
Freedom & Expression
There’s something powerful about creating a bike that’s fully yours. These caps turn a regular ride into a reflection of your style -bold, different, and impossible to ignore.
-
Make Your Bike Feel Brand New Again
You don’t need a new bike to feel that new-bike excitement. With a fresh chain setup, your old ride comes back to life - brighter, cleaner, and full of personality.
Fits Most Single Speed Bikes (bikes without gears)
Our caps are engineered for standard 1/2" x 1/8" chains found on most kids' single speed bikes.
They snap on in minutes, stay secure for years, and cover just 3 sides of each chain link - leaving the bottom open for easy cleaning and maintenance.
Patented Design Trusted by Bike Manufacturers & Pro Riders
Our caps (U.S. Patent #7571595) snap on by hand in seconds, block messy grease from clothes, and stay locked tight through ramps, tricks, and everyday adventures - no tools required, just professional results.

What’s included in the Halloween Pack?
Each Halloween Pack includes five color sets, black, white, green, purple, and orange - giving you endless ways to customize your chain for the season or mix them year-round.
Which bikes do these fit?
Our caps fit all standard ½” x ⅛” single-speed chains, including those on BMX bikes, fixies, cruisers, e-bikes, and other single-speed models.
How long does it take to install?
Only a few minutes. Line up each cap with your chain link, press until it clicks securely, and you’re ready to ride. No tools or grease needed.
Can I still maintain or lube my chain?
Yes. The caps cover three sides of the chain but leave the inner side open so you can still apply lubricant easily when needed.
Are these just for Halloween?
Not at all. The colors are bold enough for Halloween but look great year-round. You can mix, match, and reuse them any time you want to change your bike’s style.
