I’ll start with a couple of mine:
-
Terry Barentsen (fast-paced urban rides, mainly in NYC)
-
BCpov (MTB rides as well as some trail building stuff)
-
Shifter (informative videos on various topics relating to cycle commuting)
-
One Cyclist in Lisbon (pretty much what it says on the tin, lots of silly city cycling moments in his compilations and as well as longer rides outside Lisbon)
-
Ed Pratt’s Unicycling The World series (I know it’s not a bike, but it touches on a lot of just cycle touring in general)
Not Just Bikes is such a good channel, I share their video on winter cycling in Oulu pretty regularly since I live in a snowy place where people think I’m insane for cycling in the winter!
However, like you said, I consider them more of an urbanism channel than cycling-specific.
