BMW Q6.S: We can't imagine a BMW two-wheeler without their trademark suspension system. Apparently, neither can BMW; their 27-speed Q6.S dons their motorcycle-derived Telelever body geometry. Traditional bikes--both motorcycle and mountain--use a telescopic fork system that tends to nosedive during abrupt braking. In the Telelever design, however, suspension and braking forces are separated, allowing you to brake hard without losing use of the front suspension. Liberally garnished with Shimano components, it's rugged enough for the mountain or a pot-holed commute. And as an added bonus, the 29-pound looker folds for easy storage. Price: $3,995.
