    Swapping bafang 350w hub to 750w

    Doc that sounds like a great idea. I will be doing same splicing job if I can . I would of used same housing but the 750 is literally just a hair bigger I'm talking like a 16th of a inch. I don't think I could just replace guts I know with the 500 watt version you can though. I'm having a bike...

    There's a video of Wendy with a sondors 25 amp controller running the 750 watt motor motor on sondors ebike on YouTube I can't see if she spliced it or not I was thinking of contacting her .

    Swapping bafang 350w hub to 750w

    Yes the 3 pin and the wire with the multiple wires coming out is for 750 and there is not three cables for the 750 watt is just like the 350 with 2 cables one harness cable from hub then one that goes to controller so you saying best bet is buy a new 9 pin cable and put that one the 750 motor...

    Swapping bafang 350w hub to 750w

    Yeah the 9 pin is on the 350 that came with bike both bafang hub motors I'm gonna snip that off put on 750 . I wonder why it's different though I think it's like you said just crap cause it came from Chinese vendor . They use so many wires on there setups it's like a rats nest

    Swapping bafang 350w hub to 750w

    actually wouldn't it make more send to chop my 9 pin off the 350 the one that goes to hub and just put that one on the 750? Feel like that be safer bet than messing with controller one that wire seems messy while the ones from hub are same thickness and much easier to do

    Swapping bafang 350w hub to 750w

    Hi I wanna swap my 350 watt hub motor for my 750 watt bafang almost look identical but a tad bigger so I could just swap guts of it. Question is my old 350 has a 9 pin wire from hub and the same to controller on the 750. It's a 3 prong cable connector coming from hub motor and one to controller...
