I haven't used this for grocery shopping yet, but it's great for hauling wood around the yard and bringing bikes home. And christmas trees too!!
I threw in a pic of my fiancee's bike too. I guess it qualifies as a commuter since she rides with me to staff meetings. It's a used MTB I picked up. I put North Road bars from a Schwinn Suburban on it and added the Fisher Price horn and handlebar mounted bottle cage. I think it may need different brake levers since she has small hands, but it's much better than her old Huffy that was too small.
