A Brompton can be used as a shopping cart. I decided to add a shopping stop to my regular Saturday ride. I wanted to stop at a specialty grocery store about 5 miles from my home.
When I arrived at the store, I half-folded the Brompton. Those four little wheels on the rear carrier rack (called Eazy Wheels) allow the Brompton to roll along as my shopping cart. I can use either the handlebars or the seat to push, pull, and steer my "shopping cart." I like using the seat.
This is fun! At the store, employees and shoppers acted like seeing the Brompton rolling down the aisles in shopping cart mode was totally commonplace. People made comments about my helmet and helmet mirror, but not one comment about the bike!
