The folding bicycle has turned out to be quite useful in this post-Ike time when I don't want to take journeys on the open road with traffic signals broken. I have been riding 3 miles to a meet-up point, then carpooling the 40 mile round-trip with a woman who works two blocks away from my workplace. We're both getting NuRide.com points. I just redeemed some points today for free food coupons; coffee, kolaches, chocolate, smoothies.
I love the small footprint of folding bikes, even when fully deployed.
I also used the folder on METRO on the Thursday before the storm hit. I took it on the #216 Park & Ride bus, which uses buses without bike racks or storage bins, so folding bikes are the only ones that work on those currently. I also took it on the light rail during the hours when regular bikes are forbidden, but folders are allowed. It's a nice way to get around these restrictions.
