That is great. bearings are a cheap fix. Details, details must pay attention to details.

Eastwood said:So when I ordered this mxus 3K I went with a 5T winding but as I’m looking at the pictures of the motor it has a 6, and I’ve read that mxus marks the winding on the base of the stator. If so that’s fine with me, if it’s a 6T because I was looking for hard acceleration.
E-HP said:If the simulator is right, then it looks like the faster wind motor accelerates harder, up to the top speed of the slower motor, with one and a half times the torque at that point (65NM vs 40NM):
Eastwood said:Well, The faster wind motor uses more battery to accelerate, this was another reason I went with a slow/5T as it’s more efficient with stop and go. technically you can get away with less battery with a slower wind motor compared to a 3T motor that’s going to run near 70 mph at 84 V. I don’t hold fast speeds for long and most of my riding is stop and go and especially off-road stuff. I love smashing step hills at full speed with the high torque motor :lol:
But yeah if I would’ve went with a 3T I would say 30ah minimum. With This 5T I’m good with 20ah, 20s 6p.. barely
E-HP said:Then just hold the faster motor's throttle at 85% instead of WOT and you have the exact same acceleration but slightly more efficient and cooler running:

Eastwood said:Wait are you suggesting that a fast wind motor has quicker acceleration?

This is too funny... about 20 years ago on a muscle car forum where everyone was modding their cars for quarter mile racing and road racing track sessions I remarked that soon enough we wouldn't be talking about superchargers, tunes, cams, and bigger injectors but instead we'd be talking about rewinding motors and juicing the battery voltage. And here we are!

ZeroEm said:E-HP has a point about them dropping off at the end. I can run at 33 mph but a small grade my speed will drop before the motor starts pulling hard.
I want 28 mph that is 5 mph below top speed so don't get that lag.
E-HP said:I noticed the simulator is pretty accurate for certain behaviors when I dial in parameters for my bike, then change to various voltages; or at what speed the acceleration/torque noticeably drops off, 5 mph before top speed. Can't speak for other motors, but I think Grin physically tests them.

Yeah I was thinking that today :lol: because I was laying on the handlebars trying to keep the front wheel down. I would love to test drive a bike that has like 400 phase amps or something just to see if there’s anyway I can manage to keep the wheel down.

Eastwood said:If I had a CA3 I believe I could monitor the phase amps,
judging how fast I go from 0 to 50 it has to be at least 12,000+ kW to the rear wheel.
