How much do professional bike riders make a year?
more then what you make stupido
bull riders make 50 to 80 thousand. "Starting at semi-pro, the top earner made $26,000 At the second from top-level: the top earner earned $238,000 At the premiere level: the Professional Bull Riders (PBR), the top annual earnings last year was over $460,000...and then the top-earner gets a $1,000,000 bonus (1.4 million total)."
There are plenty of different bike types, plenty of different riding terrains and conditions, and plenty of different fitness levels among the riders - so the question really doesn't make much sense. A fit rider on a road bike in flattish terrain can average 20 MPH w/o trouble, while a MTBer on a technically challenging trail might average 8 MPH. You pick which average you think is more fitting.
it depends on the bike standard and the make. Usally the parts are dependent as to how much the bikes worth, and if they are customized, brand new or expensive than you are looking to sell a bike for £200 -£300, but you need to take into consideration the condition of the bike and weather it is up and running.
Unendorsed riders pay a $71 fine and have their bike impounded. Motorcycle endorsements cost around $50 and way too much of your time sitting at the stupid DOL. A large minority of riders in Washington are unendorsed. Fight the power. http://www.soundrider.com/archive/safety-skills/non-endorsed_riders.htm
They're pretty much the same, as neither need any fuel and don't have any emissions. If you're really strict, walking is a little bit better because less energy is needed to make the shoes than to make the bike. OTOH, maybe you can use the bike instead of the car for some trips, which would make the bike better.
