Yes, I have already 5k motor use.

The 3K-Turbo will do what you require, and save you $100 and about 3 lbs. though you will probably need a higher-amp controller to get 40 MPH out of it. (with Either motor).rumme said:I'm getting ready to buy a new motor , so this may be it. Looking for 35-40 mph top speed , high torque on a 26" wheel with a 48 volt/ 45 amp output max output battery/controller. Hoping to get this performance with very little heat buildup inside the stock motor { without having to add ferro fluid, cooling holes, fans, etc...}

rumme said:How many turn motor is that ? Will it run without getting to hot ?
I'm happy with 30-35 mph with my 48 volt/ 45 amp setup..as long as the torque is impressive in a 26 inch wheel.
I just bought a Bafang geared motor that is rated at 80 NMS torque, and I wasn't impressed.

GmagNeato said:Rix, it's from the QS thread here: https://endless-sphere.com/forums/viewtopic.php?f=31&t=65972
The torque rating on their spec sheet ( https://endless-sphere.com/forums/download/file.php?id=178390 ) is actually listed as 172.9N.m for the 5T I believe.
I'm not sure if or how much the turn count affects the torque rating. But the KV for 3T 205 50H is 15.42.
I am in the group that goes lower turn count is better.
