1500w hub motor rpm

I have done a little more testing with the 1500w hub motor. I think that I am
happy with the current winding. I am giving the motor 65A battery, 180
amps phase.. and it is like a rocket now.
The efficiency is very good.. the most efficient hub motor I have
tested.. good work!

http://www.leafbike.com/products/e-bike-hub-motor/gearless-20-24-26-700c-28-29-inch/newest-48v-1500w-rear-spoke-hub-motor-electric-bike-motor-998.html

But I want to be sure about the winding for my post about your 48V 1500W hub motor,
because your webpage shows lots of different RPM for the same motor (
this is confusing )..

If someone orders the hub motor from your website.. they will receive a 16*4
turn motor, which is 650rpm @ 49v = 13.26 kV
And the 13*5 turn motor would do 550rpm @ 49v = 11.2 kV
Is this correct…?

P.S. If you are interested in having a hub motor reseller.. I told someone
in the USA about your hub motors and told him about my tests.

I got the hub motor and have tested it. It’s a great hub motor, but the winding is too fast for a 26 inch,650B,700C,28 inch,29 inch hub motor wheel.It’s better for 14 inch,16 inch,18 inch,20 inch,24 inch bike motor wheel.
The no load speed on the hub motor I received = 640rpm on 49v.

I notice on your webpage that you sell stator windings.. I was wondering
how many turns this hub motor has.

Is it possible that you could sell me a stator winding with one more turn that could do 500-550rpm on 49v?

16 * 4T 650RPM
13 * 5T 550RPM
11 * 6T 450RPM
9 * 7T 350RPM
8 * 8T 250RPM
7 * 9T 150RPM

1500w rear hub motor with bike rim

Q: I’m looking for a powerful direct drive rear hub motor for a 26″ MTB.
I’ve been looking at this motor:
http://www.leafbike.com/products/e-bike-hub-motor/gearless-20-24-26-700c-28-29-inch/newest-26-inch-48v-1500w-rear-hub-motor-wheel-991.html
1.Is this the best 26″ rear hub motor you have or do you recommend any other bike motor?
2.Can this hub motor be delivered with a temp sensor installed?
3.What type of gear cassette will it be able to fit with a 135mm dropout? (How many gears)
4.Can this bike motor run higher than 48 Volts? 52Volt maybe? Or 72Volt?

A: 1. We have 26 inch 48V 1500W rear hub motor. We recommend this one
2. With temp
3. Max 7 speed and fit for 135mm dropout. Default for screw on sprocket.(If you need to install cassette sprocket, should leave message when you order.
4. We recommend work at 48V battery.(Max 60V)

Q:Can this same rear hub motor also be delivered with a 27.5″ x 50mm tubeless rim?
I will install a 7-speed cassette sprocket, so very good that it supports this.

A: 27.5” and 26 inch are different rim.
If 27.5” rim is smaller than 700c and larger than 26 inch rim?
* If you need to install your 7-speed cassette sprocket. Please Note when you order.

Q: I want to use the newest 1500w hub motor in this bike:
If you press the green + (View all components) on the page you can see that it has 27.5 INCH x 50mm, tubeless ready rims and 142x12mm (Ai offset lacing) rear drop out.

So I’m wondering if you can deliver the hub motor with a rim that’s the same dimensions as the original rim?

A: We have some sample of 27.5 inch rim in stock. Looks the same to the one on your site.
We only ship two 27.5 inch hub motor kits to USA one time two month ago.(ONLY one customer need this 27.5 inch by now)
This 27.5 rim is smaller than 700c and larger than 26 inch.

Q: This sounds good. Thank you for even taking pictures.
How wide is the 27.5″ rim you have? (How many millimeters)

1500W Leaf Motor with 20″ x 4″ wide “Fat Bike” wheel

Q:Do you sale 1500w or higher hub motor laced into wheel that is 20” diameter by 4” wide for fat tire bike? If so, what are the dropout width options for axle? Can axle dropout width be 150mm wide or even wider? I have a bike frame with 170mm dropout width. I can use torque arms and spacers to fill some of this space, but not too much.

If available please quote price for:
~1500w newest model hub motor with 20” diameter x 4” width wheel (pre-laced service)
~Need motor/wheel laced with 1 cross pattern. Radial lacing is acceptable but not preferred. Black spokes preferred.
~Need 150mm or wider axle dropout width.
~Need turn count which contains HIGHEST AMOUNT COOPER FILL
~Need temp sensor pre-installed in bike motor
~Need single speed freewheel (11 or 12 tooth preferred) pre-installed
~Need SHIPPING to U.S

Also, can you sale with 750W sticker or engrave on bike motor?

A: We can make this 20 * 4 wide Fat Bike wheel.
Please click below site. This is our 20 inch 48V 1000w Fat bike wheel – It’s 20 inch bike conversion kit for fat snow bike.
http://www.leafbike.com/products/diy-bike-conversion-kit/20-inch-electric-hub-motor-kit/20-inch-48v-1000w-rear-hub-motor-beach-snow-fat-tire-bike-conversion-kit-1057.html

We also can make 1500w bike motor.
* 1500w with 20 * 4 — Okay. (If your tire is 20 * 4 “, 20 * 3” rim is much better fit for 20 *4” tire. Also,we have 20 *4” rim)
* Please click above site. Wheel looks the same this one.
* At least the dropout 170mm or more
* With temp
* Can use single speed.But min 16 tooth can be installed on this motor. (Can’t use 11 or 12 tooth,only no motor hub use this 11,12)
* Ship to USA is okay.

Q: The tire is “Stingray tire” type. 20″ * 4 1/4″. If you think 3″ wide wheel will fit better ok. 16t freewheel is ok. Rather 1500w if motor will handle more power. Which turn count do you recommend for speed 35mph?

A: We recommend leaf 13 * 5T winding rotor.

26 inch electric hub motor kit for the dropout 160mm fork

Q: Are you able to supply a rear hub motor kit wheel (36v @ 500W – 750w) for a rear dropout of 160mm?
I have an existing e-bike that uses a 250w geared rear hub drive on a 26 x 1.95 wheel.
It has a 7 speed gear, standard 160mm disk brake and a bike mount (frame) width of 160mm.
I would be happy to go from a geared (small hub) to the larger electric bike motor kit type.
The existing bike frame is steel (not carbon or an alloy) so I may be able to ‘bend’ the rear forks… (fit).
I have included a PDF diagram (attached) to show the existing rear hub motor fitting size.

A: Yes, we have dropout of 160mm 36V 750W electric bike motor.

Q: With the new Leaf controller and LCD, I know I can limit the maximum output speed of the 750w Direct Drive hub motor to a set (safe) maximum speed for each PAS mode 1 – 5.
With our Australian laws, I want to honor speed and safety – yet have a safe speed and torque (reserved) for hills.
I respect that you have kindly supplied my order with a 320RPM hub motor ( a good choice).
My question is: “Does the max speed by set by LCD / Controller economically limit the maximum current sent to the hub motor”?
I am talking here about battery life with a low speed LCD / Controller setting ‘modulating’ the full power sent to the hub motor.
So if I program the setting to say 25Km/h, then is the torque output effected at speeds less than the given 25Km/h?

A: Yes, if you set max 25kmh by LCD, motor will work less than 25kmh.(You can set max 10kmh,11kmh,12kmh….48kmh,49kmh,50kmh)

1.Press “SW” from LCD. Turn on LCD
2.Press “up” &”down” together for more than 2 seconds in 3 seconds after LCD display – Then “72” will flash.
3.Press “down” or “up” to set any max speed. Press “SW” one time to save. Then “26” will flash. It’s tire size. Don’t set. Still press “SW” one time to save. Then “kmh / mph” will flash. Don’t set. Press “SW” one time to save.
4.At last, press “SW” more than 2 seconds, then will be back.

There is a Three button switch inside parcel.

** Black switch (be Left side / Middle – motor works forward. Be right side, motor works backward/reverse)
** Red switch (Be left side / regen off. Be right side / regen on)
** Green switch ( When motor is working, press this green switch one time. LCD is display C, motor will work as the same speed) – Re-press this green switch one time, or press brake lever, turn throttle to max, motor will stop.

Buy an electric hub motor kit

I’m very interested in buying an electric bike kit as soon as possible for my bicycle (26 inch rim )and I found your page but I would like to know about all the models you’ve got from the smallest to the biggest and strongest ;and THE PRICES of these and all the specifications:
speed (km/h)
torque
durability
distance of charge
weight (of the electric bike kit)
weight (it can carry)
does it come with battery what type of battery (lithium ,lead)
voltage
amperage
watts
rims what type of rim
recommendations of each one

I’m not really interested in the rim (inch)but some info would be good ,I want to find out about these brushless hub motor

I need something that lasts 70 km and runs at 60 km/h on a flat surface with lots of power like to move 150-180kg of weight (bicycle me, hub motor, and a little extra weight)

what does the electric bike kit include?:hub motor battery controller throttle, brake lever, pedal sensor BATTERY MEASURE etc.

and what combinations can the electric bike kit fit 36v – 48v – 24v -6,7,8,9,10 amps if possible

the same for the rear motor and for the front hub motor

(front rear) sizes, types ,performances PRICES and everything they can do the thing is that I live in wide mountains so I need something strong but lasting for I live far away of the city

One last thing if you do delivery to Mexico (VERACRUZ or D.F.)(or nearby) and if possible the price of delivery or just an idea

I’ll wait you’re reply and see what I can do.
Thank you very much.

Technical problem with a 20 inch 48V 1000W bike kit – problem solved

Today I hit in a technical problem with the 20inch 48V 1000W bike conversion kit (Item ID:#LBCK20481000FN). I was riding for a shorter distance steep uphill in level 5 and suddenly the hub motor was making an obscure humming sound and was vibrating very strong. So I stopped immediately and shut down the system. I checked the hub motor and the cable for overheating but they where just with normal temperature. After a while, I already turned to go back downhill, I started the system again but the problem still exists. It seems that it is maybe a problem with the controller because now there is no reaction in changing the power level (1-5) or turning the throttle on. The hub motor gets only around 10 Amps with a max. of 590W (measured with a installed Amp/Volt meter in between). When starting pedaling or with the throttle with low speed the vibrations are immense but when I gain more speed the vibrations are reducing to a lower level but they are still there. When staying still and pull the throttle full, so the tire normally can spin free, only the vibrations and a loud humming sound exists. I know I do not have any warranty more leftover on this system but maybe you have an idea how I can repair this for a budget price.

I already solved the bike conversion kit system problem.
Funny what unexpected small things could cause some different technical reactions. The problem of the bike conversion kit problem above was, that one of the 3 phase cables to the motor was broken. By the effect of the depicted problems above I really thought that something in the controller was burnt-out but happily I could find the broken cable very soon so now everything
works fine again.
