Great to hear that you're enjoying cycling to work. I would say on average between 15-30 minutes; however, also in a small university town in the US for now, and haven't been able to ride as I wasn't able to find a cheap bike for my short stay here. Have been working on a small project on investigating bike-use and the possibility of starting a bike-sharing program on campus or in the city though, as mentioned. Thanks for your thoughts!
