The Best Bike Lock. Leave a bicycle locked up on the street, and a pro with the right tool can spring it faster than you can buy a Slurpee. We're not bike thieves. We put four popular brands of locks against those hand tools, and the bike thieves' weapon of choice. In the end, we found some locks that can buy you a few extra seconds of security. But the results conclusively proved one thing: Your bike is never really safe outside. Testing Methodology.
These four mid- range locks (~$5. All of these manufacturers make locks that are more expensive and heavier, but we chose these for their affordability, convenience, and for the fact that these are the locks we see people using all over NYC. They're made of hardened steel and outfitted with complex locking mechanisms. Beyond the security of the locks, we looked at cost, weight, and how well the locks mount to your bike. We went to work with each of those for five minutes and measured the results. We fitted it with new Bosch- branded 4 1/2- inch- diameter, 7/8- inch thick cutoff wheels. With a little practice, let's just say, we didn't need the full five minutes to measure the damage.
For a pro, a bike locked up on the street must look like free money. Lay out $1. 00 for a power tool, and you could just go get a new bike. And these four locks are usually all that's there to stop you. Fourth Place: Blackburn Leavenworth. This Blackburn Leavenworth's unusual hexagonal design is coated in thick rubber, which protects your bike, but that's where this lock's advantages disappear. It's heavy, considering it's the smallest lock we tested, and the shackle's angles make it trickier to squeeze onto a tight post.
Furthermore, the keyhole is finicky and often requires some shaking and banging for the key to turn. The mounting bracket attaches easily to your bike with a hex key, but the lock rattles a lot while you're on the road, and it slides around on your bike's frame. The bolt cutters only made some dents, but we were able to cut nearly all the way through the lock with the hacksaw in just five minutes. It didn't even last a minute against the angle grinder.

Abus Sinero 4. 3 Specs. We just wish the company's mounting bracket was better. It attaches to your bike with a one- way sliding tab, which clicks tight, and then you clamp it down with an included hex key. Still, the lock wavers left and right while you ride. We ended up abandoning the bracket altogether.
But at least the lock's finish doesn't scratch your bike when it's threaded under the brake cables. And, when opening and closing it, the key turns smoothly in its hole. The angle grinder, on the other hand, sliced through it in two minutes. Still, we had it locked up tightly, and even after the lock had been cut, it required some effort to spring the bike free. Kryptonite Evolution Series 4 Standard Specs. The lock clicks into a sturdy, secure mounting bracket that doesn't bounce around while you're riding.
