With 30-inches of band, this one uses a combination, not a key, making it especially convenient when you're riding without a backpack or zipper pockets.

4. Titanker Bike Chain Lock

  • 6-millimeter chain lock
  • Dust and rust protecting cloth
  • Easy to carry around
  • Affordable price

Although a high-end lock usually costs around $100, you don't have to break the bank if you just want a reliable, protective option. With nearly 2,000 five-star Amazon reviews, the Titanker chain lock is the best bike lock if you want a simple, price-friendly option.

This chain lock has 6-millimeter heavy-duty links (with a cloth cover) to help prevent damage and rust. This chain wraps smoothly around your bike for ultimate convenience.

5. OTTOLOCK SIDEKICK Compact U-Lock

  • Steel U-lock
  • Compact and lightweight
  • 2.75" by 5.75" dimensions may not fit every bike

Perfect for commuting, OTTO's SIDEKICK is a sleek, compact option that provides safety without the added size or weight.

However, considering its small size (about 2.75 inches x 5.75 inches), you should measure the middle portion of your bike to make sure it can fit around it (and whatever lock point you choose).

4 Tips to Finding Your Best Bike Lock

1. Understand Pricing

When it comes to your bike's safety, a good bike lock is worth the investment. Generally, you can expect to spend around $100, according to Seacat.

"More often than not, the more you spend, the better protection you will get," says Seacat. "The sweet spot for truly protecting your bike seems to be around the $100 mark."

Although that isn't exactly cheap, usually these more expensive locks come with an anti-theft guarantee or insurance plan, he says. Brands like Kryptonite often offer a several-thousand-dollar reimbursement if your bike gets stolen while using its lock. They also often supply you with several keys or, if you lose yours, replacements.

2. Think About Your Security Needs

How often are you going to be using your bike lock? How common is bicycle theft in your area? How long do you usually leave your bike alone? Consider these questions before you buy.

If you're going to be commuting into a high-population area and leaving your bicycle alone throughout the day, investing in a stainless steel, heavy-duty U bike lock is the safest option.

Band locks are best-reserved for short and quick stops on your ride, according to Seacat. Despite being made with strong materials, they sometimes don't hold up again high-level scissors or cutters. (Zip-tie bike locks are even less secure, which is why we haven't listed them here.)

3. Consider Convenience

Although U-locks are some of the best bike locks for security, according to Seacat, they can be a little heavy and clunky to carry with you on your rides. If you prefer a low-key cruise to a local cafe or don't need a ton of safety features, a chain or band lock may be a better match for you.

4. Ask Questions

When in doubt, ask an expert, Seacat says. Find a local bike shop and ask an employee what kind of lock they recommend for your needs. You can also click through the products above to read more about each brand and the options they offer.
