And, as
exmechanic89 suggested, the tire sizes listed are all MTB (and Cross) tire sizes. But, the question is about road riding, so the type of bicycles should at least be revisited.
Want an all terrain bike? There are still Cross bikes that should be considered.
The Cannondale Slate on 650b tires looks fast enough. But, perhaps those are just fast videos.
But, there are plenty of other options on 700c (28"?) tires.
