Hey...Whatever makes you happy I am all for !
To each his own...If you want to ride a tricycle you
should do it without worrying what anyone thinks.
That being said.....I would never take any class on bicycling.
I wouldnt take one on tying my shoelaces either.
But if someone else does, great !
I am aware of cycling 'experts' both internet and IRL and believe the
'expertise'/overcomplication they assault one with to be turnoff to a
lot of cyclists.
