Need help building aerodynamic billy cart

In summary, the designer of a 3-wheeled billy cart prefers a design that is wide at the front and narrowing to the rear in order to reduce drag.

By trikesrule at 2006-11-30 The Raptorcart was built for my eldest son. Was built around the time of Jurassic Park (the movie) coming out. Dean asked me for a cart that looked like a Dinosaur ! This is my slowest Trike. It runs in a class where all the wheels must be the same size and they must be 12" bicycle wheels. Tough class but she's still a winner

There's a couple of thing I need to mention that are 'basics'. 1) Lube and 2) Bearings. Don't get these right and your not going to get close to Bessy. Want to know more? just ask...trikes

Usually in March and again in November (State Titles). But my partner and I travel to the mainland to race a fair bit. Going to 2012 Australian Titles at Corowa NSW at Easter. Time I went a put a scare among them.

My partner Glenda's cart runs inthe same Class as the Raptorcart as it has 12" wheels at all corners. When she doesn't race then I run the Raptorcart. This belonged to a mate of mine and has won many races over twenty years. Glenda remains undefeated for the 2 years she has been racing.
