48V,1000W, 1500W rear hub motor for 20 inch or 24, 26, 27.5, 700c 28, 29inch

Do you have a more detailed drawing for dimensions of the 48V 1000W,1500W rear hub motor? I am particularly interested in the dimension I marked “A” so I can be sure the brake rotor disc will fit correctly.

The drawing from your web site shows the left side of the hub motor on the right side of the drawing. Also, in the video the hub motor is installed backwards and the rear derailleur is just hanging off the bike on the cable. Very confusing, but eventually I understood that the person who installed your hub motor on the bike put the motor in backwards, with the wire coming out the right side even though your specifications say the wire comes out the left side.

I suggest that you make all of your drawings, pictures, and video consistent left to right, because they are presently mixed up.

Here is an example of a drawing that is correct left versus right and has all the dimensions a bicycle builder needs to be confident the motor will fit the bicycle.

If I order with a free hub to use a cassette is the free hub body replaceable?

Does it look something like this?

Do you have a part number or a link for the replacement free hub and cassette for that motor?

Thank you very much for all the information, I really like this hub motor but I need to make sure it will fit and work well for my bike.

I want to purchase one of leaf hub motor kits

I have done a lot of research and leaf motor and services keep coming up as a fine choice.

My original choice was the 3000 watt hub motor but I have already spent a lot of money on the electric bike and so that will have to come later but from what I have read this one may do just fine.

I currently run a 6T hub motor with a 48V 20A battery pack in a GT bike frame I build a few years ago and really like the way the hub motor runs but would like more speed so I ordered a new Raptor 76r frame and plan on using leaf motor in that setup so my questions are as follows:

The frame has 150mm dropouts in the rear.
From the previous build I already have a premium 48V 20A rated up to 50A output lithium battery pack that I paid 900.00 to have built so I will have to base the new hub motor and brushless controller around this for now.

AT first I was just going to get the 26 inch 1500 watt 4T leaf hub motor kit but then read it was better to have these in the 17” or 19” moto rim for this frame

Do you offer the hub motor with the 150mm axle?

I want this to run at close 40mph / 60kph the 4T should do that but I also would like the upgraded controller over the standard. What is the best motor controller you offer with the 1500 watt motor?

I also noticed you had a 2000 watt motor in the motorcycle section. Is this hub motor available for the bicycle kit and what are the specs on it?

What controller does the 2000 watt motor use?

I am going to buy at least 2 of these. One in the next week +a bare spare and another in a month or so and then probably 2 or 3 after that. I have several friends that want a bike like mine so after I get mine done will be building theirs as well.

At the least I will order the standard 1500 watt hub motor kit in either the 26 or 24 or 20 rim and then I will just pick up a spare bare hub motor and lace the rim myself.

18 inch gearless brushless hub motor for electric bike

I am interested in the 18 inch rear gearless bldc hub motor provided by leaf bike company and I had a few questions about the hub motor.

1) What is the rated torque?
2) What is the maximum torque?
3) How many poles are there in this motor?
4) Does it contain any brakes? If so, what type? (Disc/Drum/V-brake)
5) Does it contain hall sensors? If so, How many and what is their description?
6) Most importantly, is this motor a brushless dc motor (BLDC) or a permanent magnet synchronous motor(PMSM)? This greatly affects my choice, as both types are sometimes very close to each other, so I needed verification on what type it was.

7) Does it have a waterproof gradient?
8) Dimensions: I had an issue with the dimensions listed in the description compared to dimensions in the drawing for the motor on Leaf Motor site. I am actually looking for a motor that is around 16 inches, however, I chose the 18 inches because the image for the 18 inches shows the diameter being 372 mm which is equal to around 14.6 inches, which isn’t 16 inches but is very close. The diameter of the motor is crucial for my wheel choices and so clarifying what the actual diameter of this motor would be very helpful, I can’t risk not being sure of the dimensions as I am currently designing the vehicle and need to be very accurate, and that’s why a professional mechanic is needed specialized in this kind of vehicle, because sometimes people think a person who’s good with cars will be good at bikes too, or because someone know how to fix the electric of a bike would know anything about electricity at home, and for that you’ll need to hire a electric company such as Powertec.

9)Does this motor support regenerative braking?
10) What is the back EMF of this motor?
Finally, I would like to apologize if these are too many questions but I am in need of the maximum clarifications I can get to be as precise, so any information you can provide I will be grateful to receive.

A:
Please click our new site.

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

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)
