Well aside from general problems with the OP's attitude and pseudo-science, i's quite possible to achieve 44+ pedaling on a XL-RD5 with a 48-17. The 1.6 high gear yields 44 mph at 12 rpm. It would take a long steep hill to do so, and yes 50 mph is possible on a bike. I was paced by a car going through the Cajon Pass on I-!5 in California at a 50 mph coasting in a tuck (hey, I was a foolish 23 year old). The OP is unlikely to achieve that speed without a bigger hill or a bigger tailwind, and pedaling rate would be in excess of 140 rpm.
