I finally got mine rolling today, and I think I might have something wrong... On 44.4V LiPo using a 9-fet Lyen controller, it seems ok on flat ground, but show it any upward incline at all (seriously...even just the ~2-3 degree incline by my pool) and it chokes. As in, it
stops. It also makes weird noises at low speed, almost like stuttering, but I'm not sure. I checked the sensor wires as well as I could without taking it apart, and they seem to be fine. Phase wires get crazy hot though.

Those are definitely getting replaced....seriously, who thought dinky little 14AWG (guestimate...I didn't think to measure them when I was replacing the connectors) was a good idea there?
Anyways, for anyone who has this motor and has been using it, is this expected behavior? For context, this was with no pedaling at all; I haven't put the pedals back on yet..or the brakes..or the chain..or the seat..yeah, it was a rather awkward ride..
Also, for anyone who has taken one of these apart, do the side panels screw off or pop/slide off once the screws are off? Those phase wires
really need to go. I tried taking out the screws and pushing and prying at it, but I don't want to put too much force in the wrong direction for fear of breaking something.
