Maybe go for a phaserunner or buy a new motor?
I love my G510 with the Phaserunner. +3000W without a problem.
Does yours have the Hall sensors?

What size chain ring are you using?
42T currently. A 44T would also be a good choice if you like speed.

Re: Titanium Fatbike - Bafang Ultra and Phaserunner

Daxxie, what a great build! I'm about to order a frame like yours except non-fat off ali but with the Chinese new year and the delayed reply times there's lots of time for surfing for other's experiences. I'm wondering how long you've driven your build by now? Been driving it for over a year now. I...

Re: Titanium Fatbike - Bafang Ultra and Phaserunner

If you would thicken the chainstays, there would be less flex, right? I am asking because I am concerned that the flex might interfere with narrower cranks needed for a small Q-factor as there will be obviously less space between the crank arm and the (flexing) chainstay. Yes, bigger tubes would me...

Re: Bafang Ultra Discussion

I would like to ask active Ultra drivers about reliability of the G510.

Re: Titanium Fatbike - Bafang Ultra and Phaserunner

I was also considering a Titanium frame with my build, but was concerned about the durability due to the flex. Do you not see this as a concern? No, not concerned at all. Ti flexes but can withstand that flex much more then other materials. Also makes the bike more comfortable . The frame was desig...

How long are those chain stays? Chainstays are 500mm [*] If you don't mind could you repost the first image (bike geometry) in your opening post again in higher resolution?

So the Q-factor is (give or take) 230mm, this is way too wide for my sensitive knees but what I expected based on the photos from Luna's site.

Daxxie, I love your build as it is really clean! How is it then, accelerating out of the curves? Any bad load change behaviour? Rear wheel wiggling like the 750 two-stroke Kawi of Gary or my stock CB750 SOHC :lol: ? I love this frame, for me it has the perfect balance between comfort and precision....

Re: Bafang BBSHD Stone dead - after replacing controller???

It is possible that i shorted the two power supply wires to the controller when shortening the wires to put a new connector on. However of course with no power connected. Dont really get how that could ruin the controller though - since there was no power on ? It’s my humble opinion that shorting t...

I'm encountering the same issue the OP had, "Judder" while re-applying the throttle. OP fixed it with the CA but I don't have one. I emailed Grin and this is what he suggested......
