Amazon.com Product Description
Would-be thieves will give up quickly when they see how long it'll take to saw through this beefy U-shape lock from Master Lock. This keyed lock comes with a carrier bracket for stable storage on bicycles and motorcycles. A vinyl, covered body and shackle won't scratch the bike's finish when it's time to lock up. And, a hardened steel shackle resists cutting, sawing, hammering and more. The lock is 4-1/2 inches wide and 8 inches long to fit easily around rims and frames together. --Brian D. Olson

Customer Reviews

Master Lock
The Master Lock is exactly what I was looking for. I live in Chicago and have to leave my bike outside of the library, coffee shops, bookstores, grocery stores, etc. I don't own a car and use public transportation and my bike extensively, so keeping it safe is very important. I really trust this lock to help me do just that.

Don't buy!!!!!!!!
I bought this lock brand new and it broke in less than a month. The key was jammed and I had to call my college's service person to saw the lock off my bike, and he told me that a lot of people have the same problem with the master bicycle lock. The lock came with a warranty, so I mailed them the broken lock (which costs 7 bucks) and they never sent me a new lock or replied.

Worth it.
Haven't had my bike stolen yet; so I think it's a good buy. Good for just locking a single bike.
