    Rough rull of thumb 750w=1hp....so 14 kW will be about 18hp and 30 kW is about 40hp........

    18hp, would make a good bucket....

    and 40hp will make a better bucket

    yeh, my motor is rated to 18hp, or 16hp, though its hard to compare electric to petrol by hp, most electric motors are capable of constant torque thoughout the range, giving better acceleration for a given top hp than petrol, which have higher torque at higher revs (generaly). Though most electrics seem to be direct drive (no gears) so lower acceleration at slow speeds. These differences should make for some interesting racing i reckon!

    time for an update. Doesn't look like my current project is gonna be bucketable, acceleration was alright, but top speed was a little low. Was just tipping 50kmhr before parts of it caught fire, reckon it still had another 10kmhr in it, but thats still a bit off the pace.

    However it was pretty fun to ride and ill be saving up for better kit which will be suitable for racing eventually.

    Well at least you were honest about it. I prophesised about 10% likelihood of a raceable bike, but you did get a lot closer than I expected.

    So the real question is when is the dirty IC engine being sloted in so you could race?
    Don't you look at my accountant.

    fixed it for ya , and answer is whenever I get enough money , hoping to finish studying in a year, so sometime round then

    LiFePo battery. You mean the ones that seem to regularly cause fires & whose materials are strip mined (and landfilled when short life is over) then charged by coal or gas fired power stations?

    hmmm, hadn't heard that they cause fires, think thats Lithium ion batterys, rest sounds about right though, though i'll get my power from the wind generators

    In New Zealand its about 60% hydro and wind, 10% geothermal and 30% gas/coal...

    Heya Kirk.
    Yeah I know, just making the point that the power has to come from somewhere, people seem to think that EVs are carbon neutral or whatever the term is. The mining & production is the messiest part & it is all being done in a dirty factory in China 'cause it's cheap & if you can't see it it isn't happening.

    But don't worry the Emissions trading scheme will move some money from one pair of hands to the other & that will somehow change things & save the day. hoobloodyrah.

    yeh i'm not one of them people, half of one, 6 dozen of the other sort of thing. I just like the technology, and its something I can get into all the finer details and make something exactly as I want it, next one I want without the flames!

    glad to hear that you are still working on this project
    but I want video of the bike and flames

    yeh, we didn't manage to get pictures of the flames, too busy putting them out while going 50ish kmhr, good thing it was only an electrical fire!

    attaches some pics of it though
