Warning: I know nuffin; nuffin I tell ye.

But I gotta ask: Is there no advantage to getting your arse lower?

From looking, it looks like you'd be pretty much wrapped around the thing to ride it, but to this casual observer that seat position look very high. There must surely be some benefit to getting the major weight component that is your own body as low as possible?

Of course, getting the rear tail lower will also bring a benefit!
Last year I run a 160/60-17 tire and this year I want to test the little Hoosier tire and therefore I can’t lift it more down. But I also used the standard lowering links with 3 different positions in the lowest position.
For next year I will change back to chain drive and standard rim and then I will create my own link to lower the rear tail.

Took part last weekend on an energy exhibition with my motorcycle and my ex e-bicycle.
Had a lot of good conversations. People who are interested in my work and want to have my help by their projects.
Saw a lot of lucky faces by sitting down on the vehicle´s for taking a picture.
Get also some negative critic regarding do not fit to registration in GER or using LiPo batteries.
But at the end this event made a lot of fun for me and I got no a short introducing to be an exhibition presenter :-).
Well I drove to the exhibition by motorcycle and my brother took the bike.

hehe, nice one! Exhibition in winter with snow, the stand is outside and the ice cream trailer idles around aside. Wrong continent :)

I had fun, of course!
It took place at Hirschaid (near to Bamberg, Bavaria, Germany). It was a little exhibition... only 2000 visitors at two days but that was absolutely ok!
I made now some short test runs @ 650A and it feels much better than before regarding the acceleration.
I think I will go now directly to 800ARMS :-).

Good of you to attend such an exhibition. I bet your bike drew some attention 8)

If you go higher on amps and will seriously go drag racing you might want to read Cowardlyduck's work with fans inside a hub motor for cooling. The burst you will put in won't be cooled instantly but it can help greatly between runs to cool the motor back down. Here is his thread:
https://endless-sphere.com/forums/viewt ... &start=450

And I still think that if you want to further improve acceleration you should consider to add a motor on top of your swing arm just in front of the tire with chain drive to your hub motor. :twisted:

There is so much space that even the large hubmotor would fit on the swingarm behind the damper.
Than doubling the volts (or up to max RPM the motor can take) and a 1:2 reduction! I think it could do a wheelie than 8)

Well it´s 144V version motor. So actually there is no controller on the market that can handle this high voltage, except Emsiso H300 (400V, 450A) and Unitek 700/400 controller. But The phase current with 400A are to weak and also the price with 5k€ is very high!
I tested now 650A:
https://youtu.be/TzGoCUG-H8o

But only on real short distance!
For weekend I will go to 800A and check out for one run!

BTW: I found out now that the motor is not good for drag racing cause of too high Kv (12,08).
It should be lower or I should have to divide the windings but with 7T I will have one left!

In autumn I will change to chain drive!

Your Kv is too low, not too high, but that's only because of a lack of controller options to high enough voltage. Of course with a higher Kv, which can then handle proportionally more amps, high enough current controllers become hard to find. If I recall correctly the tooth count on those motors are ok to wind as 6 phase, or the other alternative is to do split windings. Either option requires 2 controllers, which is easier to find and more economical with 2 controllers to sum to the current you want.

The current now seems to be enough:
https://youtu.be/LDEAdqyNhtA

I changed now to max phase currents and got the wheel spinning by full acceleration.
Normally I should lower the wheel base distance but then I will got some problems with tire-rear tail distance.
I made also a short introduction to my motorcycle:
https://youtu.be/3oYI6uO11dk

and some nice pics at -3 Grade Celsius.

Now I installed also a bicycle lamp called Supernova to be able to take part during night runs at some events where lightning system is required. Hopefully they accepted an bicycle lamp at a motorcycle.
So it´s battery type (model: Airstream II) and I can quickly remove it.
