Biker Chains: What Are They & Why Do Motorcyclists Wear Them?

Even if you've never ridden a bike, you've seen iconic fictional bike gangs in films and on TV. The gangs in Sons of Anarchy, The Wild One, and Mad Max, all seem to have a uniform: worn leather, heavy metals, and that chain swinging from a belt. Now, it's easy to think it's just some part of biker fashion, but for most riders, that chain is more than an accessory. It's a useful safeguard.

Unlike boots, helmets, gloves, and other motorcycle accessories that protect some part of the rider's body directly, it's not immediately clear what biker chains are protecting. But anyone who's ever finished a ride, reached for their wallet, and felt nothing there will understand. That sinking moment is exactly why biker chains exist. They're designed to protect the essentials bikers carry. And that pretty much covers the things they can't afford to lose, like their wallet or keys, once they're on the road and pushing 60 mph. With a chain, even if they hit a bump or lean hard into a turn, nothing slips free. 

A biker chain only works if you choose the right one and wear it the right way. You want a chain long enough to move naturally when you sit on the bike, but not so long that it catches on pedals or gets snagged. Chains are usually about 10 to 24 inches long and you also have to consider your height, the kind of bike you ride, and what feels comfortable. Most biker wallets come with a built-in grommet or D-ring for attaching one end securely to your wallet or keyring. The other end should clip firmly to a belt loop or a reinforced spot on your pants. Avoid flimsy loops because if they rip under tension, the chain won't really do what it's supposed to. Placement is just as important. Keep it on the side opposite your throttle hand so it doesn't snag when you swing your leg over the bike.

For most riders, the best place to put it is often the back pocket. The chain should drape naturally without pulling tight when you sit or lean. If it catches on the seat or your gear, it's too short; if it drags against the frame, it's too long. Finally, check the movement. Before a long ride, shift positions and simulate stops and starts. A properly worn chain moves with you but stays out of your way. Many riders choose designs that reflect their style and customize their chains by engraving initials or adding club logos. Even though it's practical gear, it doesn't hurt to add some personal touches.
