I have a red Ricon Giant mountain bike. Someone told me it was very expensive when new, and that it's made of aircraft aluminum. It's a solid frame 27' 21 speed that is all aluminum, rims, spokes and all. It only weighs about 15 lbs. I just don't think it's worth what he told me. Who has that much money to spend on a mountain bike? He said it cost 2grand new. Iszatrue?
