Dirtbike

[Dousi]

Hello

I'm Florian, I'm from Switzerland and want to build an electric Dirtbike. The Motorcycle will be Planned now and then built in a few years, slow and steady, just piece by piece.
I'm considering the Mars Me1003, paired to get fast acceleration and good topspeed, or would an ADC FB1-4001 be better, or is it too powerful?

Performance I want is about 140-160Km/h max speed and fast acceleration, about 5-6 seconds 0-100Km/h.

Please, do not care because the Space for the batteries, I will care later, now my question is only the Motor.

I tried to calculate this, but even with a single me1003 I would get an acceleration of 2.8 sec to 100km/h. I don’t believe it…

The Sheet Elmoto 2.18 won’t calculate the acceleration; it always gets me 17.5 sec…
So, can the performance goals be achieved with the mentioned Motors?

Thanks

Hi Florian,

I'm also in Switzerland, near Lausanne, you can view my build thread in my signature,

I think it's better to use another spreadsheet for acceleration data, please refer to this thread for details:

in particular this spreadsheet, not written by me, you can find more info in the forum about it:

Thanks for your tip with the Spreadsheet, will try this out, but I have a problem, I dont get it what ist ment with the Wheel radius if its 13.2 meters. I have a Radius of about 32cm... can you help me on that one please?

Edit: got it, 13.2" are 33.528 cm ...

my bike runs 115 kmh with a 72:12 gearing. i have never tried to go faster (dirt tires are not for highspeed use) normally i ride a 72:10 gearing its only 75 kmh but lots of torque !
hey check out the new agni motor 111RDR !!!
