OnGuard's Bulldog U-Locks boast a hardened steel shackle and a double deadbolt lock mechanism that resists drilling, picking, bumping, pulling and prying.
We have sold more than 3,000 OnGuard Bulldog U-Locks since we opened with only three reported thefts.
People usually call us to keep an eye out for their bike when it's been stolen, to find out the serial number or reprint their receipt.
Pittsburgh isn't the south side of Chicago, but still 1 in 1,000 is a pretty great track record for a bike lock. We think this is the least expensive bike lock you should buy.
There are several models of Bulldog, this model is the keyed standard size (4in x 9in).
Add a double ended cable to secure your wheels to the U-Lock for greater security.
Includes a frame mounting bracket and five keys, one which has a built-in light.
Free installation onto your bike when purchased in-store.
