One of the most frequent questions I get while riding around is "How fast can you go?"
The world record for an hour ride on a trike is 70.68 Km. WWW.ihpv.org set by Pieter Pas out of Germany. Their trike is fully faired cygnushpv.blogspot.ca and not something I would be willing to ride on city streets.
I ride a catrike speed. A nice little aluminum frame trike, but no fairing.
How fast? Well I have had it up in the 70km/h range for a short distance while going down hill. My max on the flat would be about 50km/h mostly I am not concerned with going fast. I prefer just laying back and taking my time.
It is the ride that is important not the score. What ever bike you like to ride get out and ride.bike
This is more then bicycles. The conventional bicycle despite advances in construction and materials has not really improved much in the last 100 years. This is mostly because of the UCI who sets the defintion of a bicycle for most races. A HPV is what happens when we stop following this forced definition. It also expands from land into air and waterbike
