I use a Burley Travoy and pull it with a 16" wheeled folding Bike Friday. Works great. For shopping, the travoy folds on the bottom rack of the shopping cart and the bike folds into the shopping cart. I hang the travoy bags off the cart on the outside and fill them up. Usually get about 2 weeks of groceries in one run. The Travoy tracks incredibly well with the bike; I often look back to make sure it is still there, lol.
