The problem is that we weren't fit - I finished the race with only three riders capable of riding and we were beaten by 60 laps overall.
There are some serious HPV's competing now - complete carbon fibre vehicles are common and some serious work is being done with areodynamics by some teams.
Our HPV has a chrome moly chassis, carbon fibre reinforced aluminium canopy frame and a coreflute body. It weighs around 27kg and is considered fat. The junior schools HPV weighs 15kg!!!!! Top speed was around 54km/h in the race.
One roll late in the race actually ground away half of an aluminium tube on the side of the bike. It finished the race held together with race tape :hmm:
