Re: How good is Cyclone 4kw coaxial suspension bike?
I don’t know if this can be used with a side load, one on each side of the motor. If anyone remembers the gt idrive you know what I’m describing. The pedals frame and swingarm are all independent of each other https://www.vxb.com/200mm-Lazy-Susan-Aluminum-Bearing-Turntable-p/kit12879.htm I’ve had th...

Re: How good is Cyclone 4kw coaxial suspension bike?
Sorry to confuse. The motor appears to be mounted in a type of band clamp to me. And the structure/strength of the swing arm is only this piece of bent round shaped metal where the motor is. That metal may be considered sheet metal as it does not look very thick. The mount of swing arm to the frame ...

Re: How good is Cyclone 4kw coaxial suspension bike?
I’d look closely at the pictures of how that motor mounts to the swing-arm, and the swing-arm to the frame. I’m sure it functions fine but doesn’t seem ideal. I think someone stateside could do better at the design. Single speed on the left keeps your your pedals. I know you know this. Yes no point ...

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 ...

Re: What battery to choose after your last one burned your house.
Any thoughts on these Panasonic batteries? Picked up 280 from a recycling bin at work. They are in packs of 20 for 24 volts with a date of only a few years old. I will post actual pack photo soon.

Re: Neatest Mid Mount?
Larsb I’ll try some test fitting with frames I have laying around and the motor. Above the seat stays is also an option. 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.

Re: Neatest Mid Mount?
Yes it’s a qs motors qs1000 mid motor.
Crossbreak
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.

I will be if things get even more expensive. I’ve started to get state taxed on my online purchases from Amazon and AliExpress and online bike stores like Jenson, etc. Will this push consumers to a supposedly cheaper USA made alternative? Right.

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.

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...
