I enjoy my 26" commuter wheels on my Breezer.
Love the wider tires than those on my 700 mm hybrid. More importantly, the bike handles better. It's quicker and more responsive than the hybrid, even though the hybrid is a faster bike.
I have to take it up and down stairs daily and I appreciate that it isn't so tall.
I also have a folder with 20" wheels. In my opinion, wheel size doesn't make a lick of difference in speed as my folder is just as fast as my hybrid. Both are a hair faster than my IGH Breezer.
Irregardless, I prefer to ride my Breezer.
