Not the best ride home today. I took a different train home so I'd have a longer ride on the new folding bike. About a mile out from the train station, the bike started feeling wobbly. I pulled over and the rear tire was completely flat. It was fine when I left work.

I had with me a spare 16" tube, tire levers, and a seatpost pump. What I had forgotten is that the bike doesn't have quick-release wheels; it looks like I'll have to start carrying a wrench. I called a cab and tossed the folding bike in the trunk.
