Please help to ID this motor

Post by Thriller » Apr 13 2014 8:49am

I bought this motor in a kit not knowing much about it. It is a 48V 1000W motor. I bought a 7 speed cassette to fit it and then took a measurement and it is about 152-153mm wide, way wider than the standard 135mm. The axles have 12mm flats on them. It also seems odd that the spokes are not crossed? I will upload pics from my phone right away.

If I went to a single speed on the back, does it attach the same way with a screw on? I have already ordered 4 x 6s 5000mah lipo batts from hobby king and yes I am aware of the risks with them as I use them on RC as well. By the time I machine the axle to fit a 10mm drop out and have to go with a single speed is it better to go with a different inexpensive wheel or complete kit?

The axle dimensions sound like the kind found on the big motors. But the kit you bought might have only a 1000w controller.

The radial spokes clearly suck.

What's best for you, depends on what you want to do. Don't cut that axle if you want to run big wattage.

I agree, you need to have a crossed spoke pattern. I wouldn't even run it like that. I would re spoke the whole rim. sigh, its a time consuming process.

The motor looks like a clone of all the others, 9C, yescom, golden motor, etc... All 1000W. They can handle a lot.

So does the single speed gear for the wheel go on the same way as the cassette does? Just screw on? Would I have to buy new spokes since these would be to short?

You will need all new spokes. I have my motor centered with the rim and only a 5 speed cassette will fit. I have 2 tube spacers made from some stainless steel that fill the space to 135mm. I also machined spacers to space the disc brake out to line up with the caliper. Not sure how the 7 speed fits, but I'm guessing the motor wont be centered with the rim.

It does sound to me like the wider magnet motors rather than the 28mm 9c type.

To really find out, you might have to open er up, and measure the magnet width. If its the high power motor, again, I would NOT cut that axle smaller.

Respoke it, if not now you will have to later.

If it's 28mm magnets, then filing down the axle will be fine. Screw on freewheel, but I think there is a different size screw for bmx. So make sure it's the right threaded hole size when you buy a ss. A good bike shop will have it fairly cheap.

Like like that one.

Radial is not the way to go with larger rims but since it's already built.. i'd run it until it finally does break apart.

as dogman said, i would not mess with the axle diameter, strap an 18fet lyen on that puppy at 60+ amps and enjoy the ride !. :twisted:

Side note- why do some of my pics have to be downloaded to see and others do not? I am using the upload attachment button for all of them.

file size is the reason for the pictures showing up as clickies vs directly... shrink them down and they will just display.

Where did you buy it. Looks like a much more powerful motor than typical 1000W motors.

I thought that 39mm was wider than normal. But I do not know much. :?

39mm is a lot wider than normal for a 1000W motor. And standard ebike motors have 10mm flats.

For me it would depend on the type of loads you are putting on this wheel before recommending an immediate relace. I do have to admit that I don't like radial laced wheels, but if the flange is wide enough and you won't be putting huge amounts of side loads on the wheel (hard cornering with heaving loads), I wouldn't worry too much as crosses just add lateral strength, not radial.

Plan on relacing the wheel, but I don't think it's a showstopper.

You've got a real power capable motor there, I would get a bike with 150mm dropouts and put some fat torque plates on it. But then again, I would try to ride that thing at 50mph+.

What speeds you trying to accomplish?
Get a Cycle Analyst and a Multimeter, you're still a noob if you don't have at least one of each.
