Detroit vs Cleveland--without a car

I'm planning an extended car-free trip around the U.S. and had it in mind to stop over in Detroit and Cleveland because I wanted to see these cities that used to be booming, fell into a depression, and are now making a comeback with urban renewal. For instance, Ohio City Farm, located in Cleveland, is of great interest to me because it is one of the largest urban farms in America.

I've since tacked on other cities on my trip and will now need to drop one of the aforementioned cities.

Potentially Influential Factors:

Single female travel. No car. Willing to rent a bicycle. Only staying for two nights.

Not interested in sports (I know Cleveland and Detroit have famous stadiums...), am interested in street art, walkable/bikeable areas, urban farming/parks, and evidence (either in the arts, transit, infrastructure, etc.) of how the city is making a comeback.

Thanks!
