I have to take my 690 through a gate when I get home. The path is on a slope, and I got tired of trying to hold the bike and dig the key out of my pocket. It's just a gate, so it's not ultra secure, but it needed something. I found this cool lock at Lowe's that is a type of combination lock. The best part is that you don't need a key and can open it with your gloves on!
