No lock can make your bike totally theft-proof. Still, picking the right one really cuts down your risk.
Bike locks come in a few main flavors: U-locks, chain locks, cable locks, and folding locks.
U-locks usually hit the sweet spot for most riders—solid security, not too heavy, and reasonably priced. Chain locks bring serious protection but can feel like carrying a dumbbell, while cable locks are light but, well, not much of a match for real thieves.
Key factors to consider
- • Security rating and material quality
- • Weight and portability for daily use
- • Ease of use and lock mechanism
- • Length and flexibility for different locking scenarios
- • Price point that matches your bike's value
Best bike locks
If you want to keep your bike, you need a lock that actually works. The best locks balance security, weight, and don't cost a fortune. We tried a bunch—seriously, more than a dozen—so you don't have to.
Master Lock Combo Cable
Budget-friendly cable lock with basic security for quick errands in low-risk areas.
Pros
- • Set your own 4-digit code
- • 6-foot braided cable wraps around most objects
- • Super light and easy to carry
Cons
- • Not enough security for sketchy neighborhoods
- • Cable stays coiled when new
- • Vinyl coating might wear off eventually
Our experience
I've been using this Master Lock cable for weekend rides for a few months. Six feet is more than enough to secure my bike to bigger racks and poles. Setting my own code took less than a minute—just follow the little instruction slip. The lock feels light but not flimsy. When I loop it through both wheels and the frame, I'm comfortable leaving my bike for a coffee stop in my quiet suburb. The vinyl coating's still hanging in there, and my paint job's safe. Just don't expect it to stop a determined thief with tools. For the price, it's a no-brainer if you want something basic and easy to carry—I just wrap it around my seat post and forget about it.
Kryptonite Evolution Mini-7 U-Lock
Professional-grade U-lock favorite for city riders with anti-theft protection program.
Pros
- • Thick 13mm steel shackle resists cutting tools
- • Bonus cable lets you lock wheels and accessories
- • Mounting bracket keeps it secure on your frame
Cons
- • Weighs over 3.5 pounds—not exactly featherweight
- • Key can be stiff at first
- • Smaller U-shape limits what you can lock to
Our experience
I've relied on the Kryptonite Evolution Mini-7 for city commutes, and it's become my main lock. The weight is noticeable, but honestly, it feels reassuring when you're locking up in sketchy spots. The steel shackle has survived plenty of abuse in the city. The included KryptoFlex cable is a lifesaver for securing wheels—just run it through and back to the lock. The mounting bracket is a pleasant surprise. It keeps the lock secure on your frame, so you don't have to haul it in a bag. The key was a bit sticky at first, but it loosened up after a couple weeks. Kryptonite's Anti-Theft Protection program is a nice bonus. For the price, this lock nails the balance between security and convenience for most urban cyclists, even if you wish it were a bit lighter.
Jokmae Combination Bike Lock
Affordable and easy-to-use lock perfect for casual riders and short stops.
Pros
- • No keys—just set a 4-digit combo
- • 32-inch cable is flexible for weird racks
- • Weighs almost nothing and coils up tiny
Cons
- • Not for sketchy spots or overnight locking
- • 10mm cable only stops lazy thieves
- • No mount bracket in the box
Our experience
I tried the Jokmae lock on my weekend spins around town. The combo was a breeze to set—took a quick photo of my code just in case I forgot. The cable's flexibility is handy. Yesterday I managed to loop it through my frame and front wheel and still reach the rack. The PVC coating feels solid and didn't scuff my paint. At 154 grams, it's so light I forgot it was in my backpack. For coffee stops and quick errands, it's fine. Just don't trust it as your only lock in high-theft areas or overnight. It's a basic deterrent, not a fortress. But for the price, it's a handy, lightweight option that's easy to live with.
Buying guide
Picking out a bike lock can feel like a headache. There are too many choices, but really, it comes down to what keeps your bike safe without driving you nuts. Here's what I'd focus on.
Security level
Lock security runs from 1 (bare minimum) to 15 (max protection). Match the number to your situation:
- High Security (11-15): For pricey bikes or high-risk areas
- Medium Security (7-10): Works for general public use
- Basic Security (1-6): Fine for low-risk spots or kids' bikes
If you have bike insurance, look for certified locks. ART certification is a good sign.
Consider your location
Your neighborhood matters more than you'd think. Cities need beefier locks than sleepy suburbs.
Think about where you'll lock up most. School? Train station? Backyard? Each spot has its own risks.
Lock type comparison
| Lock Type | Pros | Cons |
|---|---|---|
| Chain | Flexible, wraps around weird objects | Heavy to carry |
| U-Lock | Super strong, compact | Not much reach |
| Folding | Packs down small, pretty versatile | Not as tough as chains |
| Cable | Light, easy to use | Easy for thieves to cut |
Two-lock strategy
Honestly, two different locks are better than one. Thieves usually target one type, so mixing it up makes their life harder.
Value proposition
Match your lock to your bike's value. If you spent a grand on your bike, don't cheap out on a lock. It's just not worth the risk.
Frequently asked questions
Bike theft is a real concern for just about everyone who rides. Here's what people ask most often about keeping their bikes safe.
What are the top-rated bike locks for security and durability?
The Kryptonite New York Fahgettaboudit Mini U-Lock gets top marks for security. Its 18mm hardened steel shackle is basically impossible to cut with bolt cutters.
The Abus Granit X-Plus 540 is another favorite—great security but not as heavy as some. The square shackle resists twisting and the lock cylinder is nearly pick-proof. If you want a chain, check out the Hiplok Gold. It's wearable, comfy, and tough.
How can I ensure my e-bike is secure with the right lock?
E-bikes are pricey, so thieves love them. Use at least two different lock types—a U-lock and a heavy chain or folding lock is a good combo.
Lock both the frame and wheels. If you're leaving it for a while, pop the battery off and take it with you. That alone makes your e-bike less tempting. Consider a discreet GPS tracker for real-time monitoring.
Which bike locks are recognized as police approved or recommended?
Police and insurance companies usually trust Sold Secure rated locks. Gold or Diamond ratings mean you're getting real protection.
In Europe, ART Foundation ratings matter. Go for 3-5 stars if you want the highest security. In the UK, look for "Secured by Design" locks. That stamp means the lock passed some pretty tough tests against common theft tricks.
