Bike snob alert!
True, but someone in jeans, etc on a BSO maybe doesn't know any better and maybe has little cycling skills. Someone on a high-end MTB, clipped in, helmet, lycra should have enough guts to ride on the road.
I'm totally with
@shouldbeinbed on this. Clever marketing and dare I say it, snobbery, has created an image of cycling where you cannot be a "real" cyclist if you don't wear full lycra, a pointless plastic hat on your head, designer sunshades, clipless pedals etc. etc..
This guy cannot be a real cyclist, despite having just completed 100 miles. No helmet, no lycra, no clipless pedals, but still loves cycling and has done for half a century.......
Edit: BTW, I WILL ride on the pavement - as long as there are no pedestrians using it, which happens quite often in more rural areas. It can be a sensible and safer alternative to riding on a badly surfaced, busy, narrow trunk route (think A726 Hurlet Road between Paisley and Nitshill if you're struggling).
