I live near Fort Worth, Texas and they have a bike share. It gets regular use and the bikes look well maintained. Some people use it for commuting to work, or to go grab lunch, without having to worry about parking. Tourists use it to see the city from the point of view that walking provides but still able to cover more distance. IMO I think it's easier to navigate on a bike than by car "downtown". Some roads are one way only, some aren't. You have people crossing the streets outside of crosswalks, etc and just trying to go by car without going the wrong way down a street or hitting someone can distract you enough that you can't look at the city.

Most of the reviews are 5/5 by tourists and locals. I think an annual pass is $80. There's a smart phone app which I think helps tourists navigate to the stations otherwise it'd probably be a bit scary to use when you don't know the city at all and are expected to find the stations.

I found a video that goes over the system here.
