[If you should try to roll the bike with the disklock on, it can end very badly
I'm guilty of this, just rolling the bike slowly, though, so no damage. Kind of embarrasing, nevertheless.
Yup,.. I did too,.. really slow,.. then she stopped, and
almost tipped over,... into the side of the truck.
On that note,.. I was also just using one of those padlocks you can buy from the hardware store, that has a slightly longer loop on it,... much cheaper than a disk lock, and probably just about as much of a visual deterent...
