Looking good. For the cooling vents ,how about having a scoop through the headstock like on sports motorbike? You could mount the dash and a light on it too? :shock:
Is that frame design basically a unified rear triangle system, found on the cheapest mtb's? If you ever have to pedal it its bob up and down something awful? :shock:
Would coiling small bore silicon hose around the can give a enough cooling? I was thinking of the stuff the sell for carb breathers on motorcycles. Or this. http://www.offshoreelectrics.com/info-pages/watercooling.php 8)
