Through lots of drawing and talking (and a few beers), this was the finished product alongside some 'Rad Juice' (ciders and beers) that had been re labelled as spot prizes.
The central part is laser cut and etched plastic bolted on like a standard hub to the tyre.
This was a really fun project to be a part of!
