This particular Mint Bob 6 crank is 50T, cassette is 11-24T w/16" wheels. How will that translate to riding in the city for multi modal transportation? Good/bad for flats? Good or bad for hills?
I use this:

and map out the gear inches for each bike that I own and find a pattern.
I found that I need 19" (ish) to ride the hills in my area comfortably and 85-90" to ride down while still engaged.
Then adjust or compromise as necessary.
