Electric motorbike racing

[Jonathan]

Thank you for the, er.. varied comments so far...

(Just keep off our noisy smelly bikes we love so much.!)

It's a bit late for that. In some of the practice sessions and one of the races at Donnigton we were racing at the same time as petrol bikes. They started us off 10s after 600cc (I think) petrol bikes and if you compare the time the electric bike who won our race got with the petrol race, he'd have been in the top 10.

Eddy, I'll see you and your bike at the next race then?

Here's one part I machined for the bike. I didn't actually machine many parts as the health and safety rules prevent me from using the workshops at uni, so I mainly did electrical stuff. The part is a heatsink for the speed controller on the ducted fan that helps cool the motors - one on each side. Wall thickness is 1mm or less:
