But why would somebody who is interested in expensive cars buy this bike? It is not like the Porsche bicycle I reviewed a while back, which seemed a lifestyle accessory, something you could pootle down to the yacht club on. The person who acquired a One-77 bicycle would have to be a serious cyclist, or at least think he or she is, because this is a very demanding machine. To ride, the Aston feels like many other high-end, carbon racing bikes, much stiffer than the alloy frame I own, transmitting every bump straight up your arms, but impressively responsive at the same time, and the flat, wide, leather-covered tops to the bars are at least extremely comfortable to rest your hands on.
