The outer diameter of the shackle includes plastic covering it 18.40mm. The lock is only part of what protects your bike, where and how you lock it up plays a huge role too.

This lock is pretty heavy and will probably detract thieves without an electric tool. It is easy to lock up two bikes on one pole. The only possibly better lock is one of the heavy duty chain locks available which are more bulky to transport.

If you want peace of mind with your bicycle, look no further than this lock. It's a great, small compact lock. It's made for use on a bike rack with smaller frame tubes as well. The mechanism is smooth and easy to open and lock. It's good to put another one through the rear tire in the frame.

This is a very heavy duty lock. The cover for the lock to keep moisture out, etc. It's a bike, not a tiffany diamond, so once they see this thing, they will walk away and find another, far easier, target of opportunity.

Why We Like This:

Definitely carry multiple locks with you
Heavy, and awkward to lock and unlock
You can lock the rear drop outs to the rack

Best With Combination: Altor anti grinder Bike Lock

Buy on Amazon

This lock is the ideal lock for keeping your bike safe overnight. It’s massive compared to other U-locks. They put two dimples of rubber on the shackle tips to give you a solid "clunk" when the crossbar has fully closed. This will be true for anyone riding small(er) bikes or those with top and down tubes that really close where they meet the head tube.

The saf lock is the ideal lock for keeping your bike safe overnight. It's heavy, 13.2 pounds, but the ebike battery can help support the weight. It is a custom made pick additionally it is easy to cut the frame and shackle tips to give you a solid "clunk" when the crossbar has fully closed. It's virtually vertical and that makes locking straight across horizontally to a parking meter or bike rack easier.
