I bought this because of it seemed to have a great weight-to-utility ratio. Locked my front wheel to frame. Thieves cut through it in the 5 minutes I was in the store, in broad daylight.
This lock is too small in diameter to lock the rear wheel and the frame together to anything. I jumped the gun on this lock and regret it. One could possibly lock the front wheel to a wrought-iron fence bar, but thats just the front wheel.
