Leaf / leafmotor / leafbike high efficiency 1500w motor

I do not see any Leaf 2000w motors, unless you were looking not here

If not then the seller can and will claim anything to get a sale. The same 500w motor will be sold as a 750w and even a 250w motor just to get people like you to buy their motor.

Leaf offers 2000W fatbike hub motors with wider stators.

Maybe I'm missing something but I couldn't find anything on that page to suggest it's a bigger stator other than the 2000w claim, only thing I found was looking at the motor chart it's listed as a 35h motor but that easily could be leafbike putting the wrong chart, something I recall them doing before and mentioned about on this thread.Chalo said:

Leafbike has sold the 2000w motor for scooters and wide fork setups for years. We have not talked about it here much except when they started using the axel in the 1500w motor with one side turned down and for the larger wire access on the other side.
It is 155mm wide and no cassette. Guess that is why they are selling it as a front hub for fat tires. Used to be just a rear motor for the scooters. It is not the same as the 1500w that this thread is about.

That is a good question. Think it would be worth a try. It's around 8lbs heaver, but that is a guess. Would like to get the two side by side.

Now, found this
I don't trust the add pages and info on them.
so it might not be the old 2000w scooter motor.

I'm curious to see testing of this motor. Does it use all of the same manufacturing techniques as the 1500W version? Does it have similar or better efficiency? What kind of power can it take both continuously and peak? Where does it reach saturation?
It might be an excellent choice for a small AWD microcar of < 250 lbs.

I also wonder whether there's a difference between the stator of this 170mm "1500W" rear hub:

And this 170mm "1500W' rear hub:

I can see the difference now. One is 135mm with a cassette or free wheel and the other is 135mm with out. big difference.

So they confirmed that it is a different motor and not just the 1500w one? And yeah that sucks if you could put a 1 speed on the back this would be a great light hub for high power if you don't mind the 1 speed (I wouldn't at these power levels :lol: )
I'm 99% sure the right side cover from the 2kW rear Leaf will fit on the 2kW front Leaf, and it looks like there's enough straight axle exposed for everything to work. If this does works, then it seems like a 45mm stator version of the 1500W Leaf motor that can fit into 135mm dropouts. The description says how efficient it is and the increased power, so probably a pretty good bump up. I see 12T single speed freewheels, but haven't researched how good they are yet, but 12T would allow me to pedal at around 20mph comfortably, or a little faster, and would work out perfect since I never shift anyway.
I see a Surly Big Fat Dummy for sale on Craigslist. I think it can fit at least 72V 40Ah in the frame. Add a little cooling and that would be a great hill climber; plus I wouldn't have to be concerned about accidental wheelies. I just have to figure out how to sneak a cargo bike into the garage and act like it's always been there...

The wires exit the end of the axel! Not inside between the fork and hub.

I tried my 1500W 3T out in a 20" wheel at 3 kW today with a thumb throttle. It wanted to go sideways and was uncontrollable at full throttle, which is only 96A phase current. This is with a Schwalbe Marathon Plus 20x1.75" in the rear. Without the body shell on the trike, it got up to over 40 mph on a 46.8V pack. I did not top it out, either. I was riding it rather recklessly, without the body shell, so my Wh/mile figures approached 40.
The ride was short, only about 5 miles, but when I was finished, the motor was cool to the touch.
So glad I got this motor! I just wish it were more efficient and could take MOAR power than the 7-10 kW peak people are running it at. Once I get that Mitas MC2 on the rear wheel, things are going to get very interesting. I'm highly doubtful it will hook up properly at 10 kW and 250A phase current, but who knows.
This motor is still awesome, relative to what else is available. Highly recommend.

Glad it not a disappointment. Have fun!
So I've been researching and going back and forth about what kit or voltage to run.
I have an Ariel Rider Xclass 52v and besides a battery bag, there is no simple way to mount a 60v or 72v battery.
So instead of frustrating myself with this any further can someone verify if this leafbike kits claim of 42.7mph on 48/52v is or seems accurate?
Also would it probably take forever to get up to that speed on 52v?

Those speeds are unloaded (tire spinning in the air)
That's what I was thinking.
So realistically 37 to 40mph.
This is for a 20inch fat tire bike.
Does it seem like a better idea to just order the motor and buy a sabvoton or frankenrunner controller from the start?
Getting closer to 50mph would be nice but I think I 40 would be good enough. Just wondering if it's a boring long road to 40mph or if it's a peppy this is fun quick trip to 40.
