Definitely!!! I never see a bicyclist smiling. I, on the other hand, smile every time I throw a leg over.
Serious cyclists actually take pride in being in their "pain cave" or their "cottage of wattage", where they are turning themselves inside out in the name of performance on a bike. Its completely different sort of mindset than motorcycling.
Not hate'n on the cyclists unless they pull out in front of me or take up the hole damn lane. Just sayin it's not my cup o tea. Been in the "pain cave" more than once when dirt riden!
