We know from years of feedback from readers, customers and amazon sellers, what most people want in a convenient and appropriate lock. The product is exactly that - it's a simple product that hits all the right notes. It fits street signs and most bike racks. It can easily lock a frame and wheel to a bike rack or pole. Because it's considerably long, you can lock at least one wheel and the frame without a struggle. It's just hardened steel so not much of a match for a cut off wheel.

This is a great lock for campus use. The attachment has an intentional half moon shape for round frames. It’s more heavy than other locks however the added security is well worth the small amount of extra weight. It's great for hooking up your front wheel and frame without a struggle.

A combination lock is slightly less secure than a key lock, so you sacrifice a bit of security for the added convenience. If you are looking for a combination bike lock, then this is the one. The Combo lock is a great idea, easy enough to set, and the lock is deterrent from would-be thieves. This lock is as beefy as it gets and comes with a frame socket to carry it. The combo dial is really sticky as other noted.

There is an option to purchase a sort of bike insurance with this lock, that applies if the lock is broken and your bike stolen.
