The 5 Best Bulldog Bike Locks (2023 reviews)

The onguard good lock's superior materials makes sure that it ages well with use. It is great to have a bunch of keys in case you lose a few. The smaller size of u-lock is the safest since it gives less wiggle room for possible thieves to try and steal your bike. It includes 5 laser cut keys. The key with an LED light is a nice touch too.

The lock works great but the best thing is having multiple keys to use in just 1 or. It is good value for a solid lock. The lock itself is heavy and strong. It's easy to mount and easy to use. This key may not be fully functional for long, but it's a welcome addition.

The onguard bike lock might be a relatively new release, but it's still nothing short of impressive this year, thanks to multiple price cuts and added new features over the past few iterations. Mounting brackets make it super easy to mount it anywhere on your bike. The adapter to mount it to the bike frame is nice. It is made of hard plastic. The lighted key is a nice touch. The quality is top-notch. This is a mini U-lock so is just for one bike. The bracket is sturdy, but the whole assembly is a bit heavy. It does come with a bracket to fit on your bike frame.

The "mini" size should work on any good quality bike rack, though it is not big enough for parking meters. Because of the smaller size, the lock is a reasonable weight and size. It locks easily. The double-locking action is a great thing because a thief would have to cut the lock twice to get through it.

This lock is a great size and made from good materials. It's light weight and super easy to use. The mount for the bike is great, secure on the frame and easy to take off when you need it. It comes with a lot of keys, which is great. They also don't weigh an extra 2 pounds that you have to carry with you.
