hi there! I can tell you that I bought the Townie Commute Go! 8i. I love the bike, however, I am exchanging it for the Townie Go! 8i. I am 5'5". One of the biggest selling points to Townie was the flat foot technology. I couldn't be flat footed on the Commute (long story as to why I bought the commute). It is a heavy bike and I want the stability of being flat footed.
I wanted an ebike so that I could go riding with my family, but I am a bit unsteady on a bike because I never really rode on a regular basis (except when I was a kid, I am 49 years old now). I ride now just to be leisurely and get out and moving.
