Now,
One of the highlights of nats was the first proper meeting of the OS velodrome racer division. I had not the time to finish mine however what I witnessed that afternoon was well beyond expectation.
The rules: Well, not many really. Only that the motor has to be of stationary decent. ie, from a water pump, wood splitter, generator, or other machine that is not self propelled (lawn mowers and rotary hoez are still legit).
I believe most of the high fives should be aimed at Joe Goat Flange for sparking the notion in early 2010 at the Taupo Nats there.
The second WOAH moment was at the bicycle gang summit 2011 where ROT808 Stephen and Sentra Dave turned up with their horizontally opposed 2 stroke contraption.
I’m going to guess that you have no idea what a horizontally opposed two stroke is. You may think “har yea subaru lol” but NO.
So here I will explain with a professional drawing:
Take two two stroke motors. Cut the heads off and attach them together with a belt connecting the crank shafts. No there is no head, but the compression is created between the two pistons as they come closer to each other.
Pretty cool tbh. But of course the lifted the bar again this year.
When their weapon for this year started in the car park I couldn’t believe my ears, It’s rotary powered…
So much fun and looking forward to what pops up next time.
The first person to build a steam powered bike will instantly win.
Here are some more photos from the day. Not many as taking photos of velodrome racers is insanely difficult with my limited skill bank.
