Some progress

So I went ahead...

Hello guys, Here are some progress. My programmable controller has soft acceleration parameter, so I may not stretch/broke everything... I'm still waiting for the motor..

Really nice! 6.5kW is awesome. I like the way they are both build, congrats.

Thanks, G. Current limiting will be the way to derate it. Good idea

It is, electric unicycle are expensive, specially Gotway, for what it is, but you must try and learn to appreciate, that's an awesome vehicle. I couldn't find anything to bite c3w in terms of requirements for my build. The power is twice too much and maybe dangerous I agree, but voltage, speed...

G., Thanks for your interest. I would really like a little 500~1500W motor like the one shown by Robocam. If only I could find one that handle 16 to 20S, because that's my battery/BMS setup now. Hub motor has been tried but because the axle length is really short, it won't fit unless I find a...

Ok guys, you may have convinced me. I've already bought the cyclone. Is there a close alternative, with half the power? Here is a 3000w scooter: https://youtu.be/CyU8Cso6ERM 3000W is about 4HP. That will be 25Kg per HP. @robocam, for sure I will have a body armor for testing (like motocross...

Yep. This thing is 84V, check specs: http://www.ebay.com/itm/Gotway-Monster-22inch-fastest-electric-unicycle-scooter-/332057007375 Maybe I'll need a wheelie bar :lol: I plan to use a throttle limiter based on gyroscope/accelerometer/ultrasound

Thank you @robocam, nice find! I ave all my setup for 60~72V (controller, bms, LiPos, etc..) These kits does not exist for these voltage level. This is what's brang me in this thread.

I was thinking about hub sprocket adapter like those we can find on 80cc gasser conversion Can it be used with a thin 9 speed chain please?

Any idea how I could attach a sprocket on a 55 mm hub please? I'd really want to ruin this motor because I cannot find any alternative. DD hub won't fit, mid drive is the only solution I see..

Here are some hub details..
