It's great to hear that Seattle has some form of bikeshare again.
I had the opportunity to use the old bikeshare system, Pronto, when I was there for work a few years ago. The problem was that the standard heavy, 7-speed bikeshare bikes were a pain to ride up Seattle's hills; I was told that there were vans that went around every night, collected the bikes from downtown, and drove them back up to Cap Hill. Ebikes seem much better suited for casual riders in that area.
