I was honestly surprised that Boston’s BlueBike system was not included with Tidbyt out of the box.
NYC was late to the bike share party and a number of systems in other cities use the exact same API you have already integrated to the benefit of one city. As you have for public transit, please add support for other cities offering identical APIs.
I’ve implemented my own general bikeshare feed specification app to display available bikes and parking respectively for any bikeshare provider listed at NABSA’s GitHub repository.
My fork of the community repo contains the app with all relevant code. There are still some polishing to do, but I’m pretty happy with the result.
