I'm curious about those who grocery shop with their bike's panniers, do you take them into the market every time or do you leave them attached to your rack? If you keep them attached to your bike, do you lock them in any way?
I just got a utility bike and the panniers are oversized (yay!), but are a bother to take on & off (they hook, but also are secured with a short, unadjustable buckle). My hands have trouble snapping these kinds of buckles (& more so with the cold weather): buckle_9_.jpg
I don't think the bags (with the weight of the groceries) could just hold onto the rack with just the hooks alone, if I go over bumps.
So, I'm trying to figure out either a modification to the bag for easy on & off OR securing them from theft (??), if I leave them on & go grocery shopping (usually in a market for about an hour... for a family of 5-6)
