qs 1000w builds

That's possibly not an issue if you cut the original sprocket down enough in diameter. I doubt it will fit on the inside though, isn't it pretty tight already?

True. It's 2cm large, but on the tooth side it's not really large. You are right there is not enought space.

Wait the qs 1000 has a tapered shaft now? Mine is not tapered. I just bought a 15mm 219 sprocket from lightning rods and bored it out to 17mm and it works fine.

In the axle pic they sent me it is tapered. Don't have it in my hand yet.
Boring a small one out or shimming a big one, same difference. The 3/4" one goes lower with the teeth count so that's what I got.

Yes. Or actually 1 year ago when I purchased the motor.

But how did you deal with the notch / the slot?

I will go with the larsb's idea.

Hi Guys, this motor looks great. I'm look for a replacement for my cyclone 3000. I'm running it at 72v and am having overheating problems. This motor looks much better built. I wondered if someone could confirm the weight. The spec sheets suggest around 7kg which seems a bit much? Do you think it a worthy replacement for a cyclone?

This motor is around 3kw cont 10kw peak, the cyclone 3000w is more around 1.6kw cont 5kw peak.

It spins about 4x faster than cyclone since there is no integrated reduction, nor does it have a freewheel. But if you are running the motor hard to the point of overheating you aren't pedalling anyway.

It sure is! But it will be far superior. As Tommm said it spins fast, you’ll need reduction from 8 to 12 to one depending on the top speed you want and your wheel size. I’m planning for left side drive with a 219 chain and and a nuclear controller 12f with this motor, just have to do it.
