NPR story on electric bikes.
I think it overplays the "it's so easy!" aspect of things, but I was grateful for mine today. First day back at work after a two-week vacation, it was chilly and threatening rain*, also windy, and I carried mail. Flip the assist on, baby!
*I even fished out the rain cover for my pannier, since I was ferrying paperwork and returning books to my coworkers. It covers five sides of the cube, and while I'll have to wait for a wetter day to truly test it, it shows promise.
Also, Ted Kennedy. *sniff*
