What is the “OG Series”?

The “OG Series” in OnGuard locks refers to their entry-level security range, designed for casual riders and everyday use in low to moderate-risk areas. The OG Series balances affordability, convenience, and protection, offering solid deterrence against opportunistic theft without the added bulk or weight of heavy-duty U-locks or chains.

While not as robust as OnGuard’s higher-security Pitbull or Brute series, OG Series locks provide practical security for short stops, quick errands, and general urban riding.

Who is this bike lock for?

This lock is perfect for casual riders, commuters, and anyone who needs a lightweight, easy-to-use security solution for quick stops. If you’re looking for a lock that’s simple to carry, fast to secure, and strong enough to deter opportunistic theft, this is a great choice.

Who this bike lock isn’t for?

If you regularly leave your bike unattended in high-theft areas or need top-tier security for an expensive bike, you might want to consider a heavier-duty U-lock or chain lock instead. This cable lock is best suited for low to moderate-risk environments rather than overnight or long-term outdoor storage.

Why we love it

It’s compact, flexible, and super easy to use. The dust cover helps keep the keyhole in good condition, and the tough vinyl coating prevents scratches on your frame. For quick stops or low-risk areas, it’s a no-fuss way to secure your ride without weighing you down.

Lock it, leave it, and ride with confidence—OnGuard has got your back!
