I got my Turbo Vado 5.0 IGH about a month ago, and haven't yet purchased a lock since I store the bike in my office and secured storage at home. However, I'd like to get a lock in case I need to make quick stops on the way home from work. I live in Vancouver, where bike theft is rampant. I've been looking at the Abus Granit Extreme 59 and the Kryptonite new York Fahgettaboudit Mini. Both seem quite secure, but I'm concerned the Kryptonite may not fit around the large frame and tires of the Vado. What are you all using?
