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

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.

Questions regarding your DIY conversion kits

Q:I assume your electric hub motor bike conversion kits are speed limited, consider for example your 250W 36V hub motor bike conversion kits. Usually it seems the speed limit it set to something like 25 kmph, or so.

I building a custom bicycle and I am interested in knowing if this speed limit can be configured to be higher. I guess I am thinking this possibly is the case if one can simply enter a lower wheel size when configuring the controller. Could this be there case, or is there may be some other way to do this using your kit?

Also, are you by any chance the same company as leaf bike? And if so, does this answer also apply to the e-bike conversion kits sold under that name, e.g. their 250 W 24 V conversion kits?

A: Yes, our controller has speed limit.
There is max speed display on our leafbike.com site.
We set LCD as wheel size.For 12inch,14inch,16inch,18inch,20inch,24inch,26inch,27inch,27.5inch,700c,28inch and 29 inch..
For example: our site write: max 70kmh ( You can limit max speed under 70kmh,from min 6kmh to max 70kmh)
our site write: max 24kmh ( You can limit max speed under 24kmh,from min 6kmh to max 24kmh)

Q: Thanks for the info. Just so that I understand correctly, let me ask these questions:

For example, considering your DIY e-bike kit “700c hub motor kit – front wheel, Item ID #LBCK700C24250FM”. Our your web-site, says that it is speed limited to 36.1 kmh (actually used to say something like 25 kmh, you increased it?). Though this speed seems sufficient (now) I still wonder if I can modify this speed limit in some way. Say, if I configure the controller to a wheel size smaller than 700c. If that it possible I am thinking the max speed would be increased. Is that something that is user configurable, or it is hard coded into the controller that it is for a 700cc wheel?

Is it also maybe the case that the controller that one get if one buys, say , this kit also works with some more powerful motors? But maybe it is limited to the operating voltage of 24 V?

Do you have recommendations as to if one should go with, say, a 24V or a 36V system?

Finally, I note on the web-site I list above, seems that you are showing the motor performance table for a 36V motor. Could it be that it should show the performance of the attached motor data for a 24V motor?

Just another question here.

For your 36V 250W front wheel DIY kit, the max speed is listed as 26.3 kmh or 16.4 mph. This seems that it can be a bit limiting for some jurisdictions. Is it maybe the case that you have increased this max speed also to 36.1 kmh as listed for the 24V version? And, also, here, can I configure it for a lower bike speed to make it go faster or is there some other way to increase this speed limit?

By the way, I see the advantage with the 36 V systems. You get more watt-hours in your battery. Seems like better choice for my use case.
