Electric motorbike racing

Cool project. This sounds like something channel 4 would be interested in for their programme about speed with the TT racer Guy Martin.

I think Cool Project sums it up!

A while ago; whilst visiting Jonathon at his house, he let me have a go at an electric push bike he had made. I would consider myself to be quite a "daring" individual, also overweight.

However, I lost my bottle at half-throttle. this thing went like a scalded cat


The work you have done on this motorbike is a credit to you Jon; I cant think of a better person to be involved in such an exciting project. well done.

Dont "sell out" for an office job like I did!!!

SACRILEGE BLOODY Sacrilegeeeeee I'm still in mourning for smokers and sweet smell of "Castrol R" and adjusting to those valve murdering strokers was bad enough but if they end up making everyone go to these Silent whinners I'm coming to hunt your lot down and wire your balls to those lithium Ion assassins and drain every last bit of juice into your ball sacks.!! .

BUT well done and excellent just the same hats off to you all. . (Just keep off our noisy smelly bikes we love so much.!)

Know what you mean Dean, have tried to persist with Formula E but it's S***e
without the whine of an internal combustion engine.

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

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:

This project is progressing, only 23 days to go until we go to the Isle of Mann so I'm very busy along with the others I'm working with. We now have the new custom frame, but there's still a lot to do.

My bank holiday weekend was busy on one part:



I'm currently waiting for the cells to get through customs, then they need testing and soldering into packs.

More info here. Will post more information if there are particular things people here are interested in.

Judging from the videos of the acceleration of the Tesla car / youtube/ i can only imagine what is the acceleration of electric bike with a nice motor.

Maybe that will be the turning stone in car and bike history, when they can really offer something that's better than their petrol counterparts. I see that more difficult done with bikes, cause petrol bikes accelerate really fast. However not having a gearbox will really help.

What is the weight to HP of that bike?
