    Thanks Mark, great info. Sounds like Sevcon config and tuning for the various Enertrac motors will be available soon along with the Gen4 units in-stock.

    Rock on Mark. Great to see. Looking forward to your findings, as I can't seem to settle on my design. I don't want to discover that I end up with an under powered bike.
    By that I mean getting the single and finding out that the dual would be the way to go. Trouble for me is that need to alter the swing arm.

    I'm really interrested to see your results with two Gen4 Size4 or one Size6 on a dual 603 hub to replace my 600A kelly controller and think about a powerful and smooth dual hub project...
    The only drawback is the maximum speed with a dual or single 603 hub and a 120/150V Gen4 controller, limited around 105kph (65mph) with a 41s lifepo4 battery pack (130v nom ; 149v max).
    In the same Sevcon Size8 category, the Wavesculptor200 controller could also be an other costly alternative to drive the dual hub at high speed and high power ; but it's around 5.5k$.
    I'm convinced that a dual 603 hub managed by a high voltage pure sine controller is the ultimate solution. It's a pity that there isn't any affordable HV sine controller...

    @Tango, how is the efficiency of your 602 hub motor with the Sevcon controller ? Mine is pretty good with the Kelly (around 85Wh/m), is it as well with the Sevcon ?

    My bike has always been heavier than most (465 lbs/210 kg), as am I (210 lbs/95 kg), so i've always gotten around 140-160Wh/m with both controllers (on the highway at around 65mph/100kph). In stop-and-go traffic, i'm usually averaging around 180Wh/m.

    Yep, Jon has that hub motor humming alright. It was very close to it's limit though - we could smell the varnish
    Hopefully you can find a way of getting a few more kilowatts in there, cause that's really the only downside at the moment.

    Oh, and thanks for ripping the video - they have actually cut this whole race from that video! Not sure what's going on there.

    Another option worth a look. 6phase motor with some running up to 32kW into it. ~15kg and 16 RPM/V
