Kaitlyn Jakola interviewed me last week for the Chicago Magazine blog, The 312, about how newcomers should deal with Divvy bike sharing. I think I gave some good answers. Stick to the bike lanes by using an app (although that’s hard because so many of them don’t link up) and think about the rules you would follow if you were driving a car (which assumes you know how to do that). Two of the commenters called this a scam. The first stopped there but the second commenter showed some understanding of transportation and economics so I thought that I could reply and it would be taken seriously. They said:

It seems to me like the system is designed to create extra or ‘overage’ fees. Having to stop every 30 minutes and ‘redock’ your bike is prelude to a ripoff. By the time you get comfortable riding and determine where you’re going to go, it’s time to ‘redock’ then…

It doesn’t seem like the commenter knows how bike sharing works: think of a taxi that you drive yourself. The bike taxis are available at predetermined stands around the city. It’s there when you need it and you don’t need to own the vehicle.

Regarding overtime fees… The average trip taken on Divvy bikes is only 18 minutes long, which the Chicago Tribune – part of the same parent company as Chicago Magazine – reported on. That coincides with the average trip distances Americans and Cook County residents take. The Southern California Association of Governments, the federally-designated Metropolitan Planning Organization for the nation’s largest regional planning area, found that 80% of trips residents in that region were less than 2 miles long (.pdf). This matches what the Chicago Metropolitan Agency for Planning, the local MPO, found for Cook County that the average trip distance was 3.0 miles and the median trip distance was 2.3 miles (.pdf). Both studies’ figures aggregate trip mode, so this includes all trips people make by bus, personal automobile, walking, or bicycling. All of the distances are bikeable in 18 minutes.
