Re: qs 1000w builds

If you can take a picture of the one you want in the correct tooth count, but incorrect center mount I may be able to help with a cad file. Please make sure there is a tape measure or ruler in the picture, I prefer metric. A lot to ask but this is how I work. I’ll double check the diameter size when...

Re: qs 1000w builds

The motor shaft is 17mm in diameter with a 5mm key down the side. The shaft is about 18mm in length.

Unconfirmed. Please test print with a 3d printer before sending your file out for cutting. Don’t know if nominal or actual etc. I’m not responsible basically. Please confirm on the motor you receive.

Re: Neatest Mid Mount?

Grantmac Spins fairly easily. More resistance turning very slow but not much if you spin anything above the slowest. I’ve thought of this also with this motor. In my mind it would have to be left side drive, zero free wheels and preferable single stage reduction right? The point is for regenerative ...

On long cruiser bikes you also have behind the seat tube but down low and inside the frame. I’m shooting for larger 27.5” x 3” tire on this ride but I’ll check for you smaller whe...

Re: Neatest Mid Mount?

The measurements of this motor the Qs1000w mid motor. I’m going to use a necular controller 12f probably at 75 volts. Going to do a second 3d print of the main part any day. It has minor tweaks. Still don’t know the weight it is heavy, but appears to be high quality.

Yes it’s a qs motors qs1000 mid motor.

I can provide measurements and the weight soon. I’ve pondered the inlay of metal with my designs and while printing. I’ve thickened my printing and go solid 100%. I will post a screen shot of the cad art soon. I only use PTEG filament.

Re: Neatest Mid Mount?

Where I’m at now.
I used chopsticks as I haven’t measured for bolt length yet so loose fit. 69 hours of 3d printing for this. The main part was 50 hours, my longest print so far. About 9 ish hours each for the tube clamps. All printed with a solid 100% infill for strength.

Re: Magura throttle set up

I had the same issue as a yourself but with the domino throttle. I used a 10k trimpot, the little knob type to easily adjust. I did find wiring diagrams that used the grounds. I choose to just use the trimpot inline with the throttle input voltage to reduce it. Think it’s the outer two pins and grou...

You should never pay in full until the bike is ready to pick up. If anything a third to design the bike and get things going. A third before or after the parts show up and the final third when you see the FINISHED bike and are picking it up that day. That last third is the builders profit, not all b...

Re: Cyclone 3000 un-smooth throttle response

Check your rear gearing. A large sprocket in the back gives a lot of torque. This is great for rocket take offs and hill climbs but the force pulling you back and you inadvertently advancing the throttle can be scary if you’re not prepared. Think this is called a whiskey throttle from the gas motorc...
