Hello Noamsal,
i have the GNG gen 1 kit but i think that motor should be the same. My topspeed is about 60km/h (vary depending on gearing) at 2200w adjusted in Cycle Analyst. The 72 volts are no problem my motor only get handwarm. Maybe you get trouble with mounting the kit on your Frame because...
Hello dusan,
i machined a bushing with BSA thread where i screwed in the bearing cups. The freewheeladapter at the primary side is fixed and for the position from left to right i cutted spacers and used an old ahead cap to adjust it.
I think bmx bearing cups are better than Shimano BB because...
Now i finally improved my jackshaft with BMX bottom bracket and 3/4 inch keyed shaft. I have also installed a new freewheel on the primary side and upgraded the secondary to 219 Kart chain.

I like the way LightningRods goes with the kit.
Here are my latest Updates:
The bike still runs great.
I replaced the 26inch rear rim for 24 inch Spank Stiffy rim. Now the bike has a better acceleration and the steering angle feels better.
My chainguide is working now. No chain drops for over 100km offroad riding.
I added the Kelly thumb...
Here are a few recent pictures:
This week my new 12Fet Lyen Controller and the Lightning Rods upper sheets arrived :D
Today I installed everything and tomorrow's test ride!
