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)
