I was riding both the Lakefront Trail and the Des Plaines River Trail (full length of both) last week on my Swift. I typically stay near ORD on Chicago trips, and take CTA trains into the Loop. Did so with the Swift... just fold it and carry it through the turnstiles, holding it over the turnstile spokes. Several pax on the train asked about the bike. I saw no other folders ... the Loop is a bikeshop desert. The only riders faster than me on the LF Trail were all-out roadies... no MTBs were faster. I was alone on the DPR Trail except for a few trail runners. So ... the Swift is the bike for the Windy City.
