I might be interested in buying a bike soon if I can't sell/trade my car for something else. I can't justify putting $$$ into the maxima to make it faster as it would take WAY too much money.

1) Anyway, does anyone know of any good websites/forums/online classifieds to find a decent bike?

2) What is considered high mileage for a bike?

3) What are good brands, suzuki, honda, etc..

4) I'm 6'2 and 220lbs, do I need a 600 or 1000 to start with?
