A bicyclist has bigger stones than most. Try a century sometime. Let gravity spill you down the BRP from Mount Mitchell to Asheville. Same handling as motorsickle and about the same speed too. Then after the road bores you, go to Tsali and ride the Left Loop. 12 miles of single and double track nirvana. Two wheels is 2 wheels. Funny clothing? Ha! How about chaps? Saddle butt beads. Vivacious inferences can be made of any sport. Each has their own 'better gear'.
Cyclist yes, Bikers no!
The defining demarcation being a throttle.
