Some of you might know I acquired a near-mint Brompton a few weeks ago. I had found a bag for it (free), but was looking for something more along the lines of a wheeled case, and not hundreds of dollar either.
Went on a trip to Luggage Warehouse in Chicago (2876 N. Milwaukee). There, I found a Voyageur soft-sided bag with zippers, 2 handles & 3 sets of wheels for $30. I brought along my bagged Brommie and it just fit, so the uncased bike fit a skooch better.
BTW, store was definitely one-of-a-kind territory. Returns, closeouts, overstocks, etc. But all super cheap. Most expensive item I saw was $75.
