Not fast enough ... actualy, BF just delivered a 16 lb Pocket Rocket Pro to this 73-year old guy who was at the front of the pack on PACTOUR Desert Camp http://www.bikefriday.com/desertcamp2010 every day:

Bob Kenner. Shown with Lon Haldeman. He rocks!
I managed to stick on his tail at a steady 22 mph on a demo 16" wheel Speeding tikit for about 10 miles. Bob said I started to "get the wobbles towards the end at 23/24 mph" - due to uh, a comparative lack of fitness. Lon did a quick calculation in his head and said "you should have been able to stick on at 28 mp/h!!!!!". Need more Sustained Energy in my bottle! Was also great to meet some TE gals in teh lobby fore and aft Week 3 of camp.
