Well, yeah, that’s what I’m saying. FWIW, in most cases a decent 6374 motor will max out the current capabilities any esc, especially if the rider isn’t a fatass.
It’s covered in a different thread, but the lower resistance same kv motor has the same torque for the same motor current, but the lower resistance one has more motor current for the same battery current, so the larger motor gets more torque at the same speed for the same battery current.
Isn’t the difference in resistance almost negligible unless you’re going from something small to something really big?

Exactly. I wouldn’t expect the difference between a 6355 and a 6374 to be more than a handful of percent under most conditions.
I could totally be talking out my ass though, it happens.
However another consideration is that larger motors take longer to get heat soaked - not a problem for some people, but definitely a problem for larger riders or hilly areas
With motors overheating, braking gets reduced too.
I think it could be noticeable…
70mohm to 20? That’s a huge difference.
Sometime this week I can give you the resistance values of a flipsky 190kv 6355, 6368, and 6384
Since things are already confusing, throw cooling into it
A bigger motor with poor cooling can have lower continuous power capability than a smaller one with good cooling. At the same time the bigger one might also have lower efficiency due to higher rpm related losses, the power necessary to just overcome all kinds of friction is not small, specially on bigger motors
A big advantage of big heavy motors is thermal inertia, they can handle a huge torque spike for seconds or minutes before overheating
In truth, all depends on your riding style and no definitive recommendation can be made
How did this setup work out for you?
Currently running 205kv on 16s. Soon to be 18s. It’s loud, fun, no problems yet.
Awewome! I have the same satup in my new build.
No problems with hot motors?
They get pretty toasty, but since I’m running reachers that’s fine. About 80C on a hot day riding up some steep hills at around 50kmh. I’ll only worry about them at 100C since they’re built for higher temps. That’s plenty of headroom.
So you’re saying that you can use scrambled eggs as a temp indicator?
If it can toss a salad too…
Raw eggs vs 11k rpm brushless motor
if youre looking for max power or max torque the more gearing and higher kv the better. maybe, or may not more efficient, but the MAX will be higher.
its stuck saying im writing to you @Evwan
Im at 16s, 11:59 ratio and 175mm wheels.
Havent tried it yet though. I would love to know the torque but cant figure it out.
