    Polaris Outlaw EV conversion

    The ME1616 motor weighs about 48 pounds or about 22kg. Pouch cells from Bestgo for example have a density of about 220 watt hours per kg. 11kwh would be close to 110 pounds. 160 pounds of heavy electrical components plus 200 pounds of frame (just a guess) brings it pretty close the original...

    Polaris Outlaw EV conversion

    You won't always be using 250 amps, sometimes more and sometimes less. I recommend using the Excel spreadsheet that is floating around somewhere and putting some numbers in to get an idea of how many watts are required for the speed you want to go. From there you can divide battery pack capacity...

    KTM 200 exc goes electric

    Those numbers are super helpful as I plan mine and try to figure out how battery I can stuff in there. What kind of tires are you using on sand?

After looking at the Vortex, it seems like somewhat of a hassle to mount a hub motor as a mid drive. The axle has to be very...

    SilentEnduro conversions

    Everything that I can find shows the 205 and 138 as hub motors that are only rated around 3000W. But the pictures don't look like they use hub motors. Am I missing something? I'm new to this so thats possible, but my electric skateboard has a 3000W motor and weighs a lot less and goes a lot...

    First post, electric motorcycle build.

    Don't mean to revive an old thread but I'm super interested in your build and I'm thinking I'll be doing something very similar to it. Do you have pictures of everything completed or could you share on how it went and if you're pleased with the results? I will be doing a dirt bike in the near...
