This one 100%
Re: QS 3000w midmotor
Do you have the mounting figured out yet? I have a rough idea how to do it but ideas are welcome. I'm soon posting in my Rieju thread
Ride on!

Re: QS 3000w midmotor
Its on the bike for a couple of months now and i am using the support for the suspension to attach it 

Re: QS 3000w midmotor
Could you take some pics? I will use this mounting also but since i will go with belt drive then the assembly needs to be stiffer and alignment is more critical..
Ride on!

Re: QS 3000w midmotor
Under the motor i attach it with bolds, i drilled new holes with tread.
Re: QS 3000w midmotor
Very nice, was planning pretty much the same thing.
BTW are you using something stronger than a 420 Chain?

Re: QS 3000w midmotor
How does it hold up? I'm kinda worried that I might need a 520 Chain at +10Kw.
Also how is the noise at higher speeds?
I'm not worried that it'll be too loud. I'm just curious.

Re: QS 3000w midmotor
The 420 hold up good there is a little stretch but that is normal i guess
Re: QS 3000w midmotor
Nice mounting! I will need a position to the front of the pivot point by 12cm to fit the belt length so i'll need to make an extension to fix the motor. Some things are better with chain..
I will not miss the oil splatter though

Re: QS 3000w midmotor
Do you know how many slots this motor has? I cannot find any data.

Re: QS 3000w midmotor
Only thing i know is 5 polepairs, what do you mean by slots?
Re: QS 3000w midmotor
slots in stator. I thought you maybe knew since you had that picture of the rotor?

Re: QS 3000w midmotor
Made a 3 hour trip today with the 72150 set at 250battamps and 450 phaseamps this at 58 volts.
The motor runs strong and with no overheating, i am very happy with the motor
Tested also foc and set it at 150amps, now with a 6 to 1 reduction it can run at 90km/u

Re: QS 3000w midmotor
That's 14kW max...
Great motor indeed!

Re: QS 3000w midmotor
Bionicon do you have a full pic of your bike with the QS 3000? I searched but couldn't find it

i dont have a picture of the other site here some bad movies:Re: QS 3000w midmotor
just found one from the other site:
Re: QS 3000w midmotor
nice, the QS 3000 looks like it was made for that frame. Is that a custom frame? Do you have a build log? I'm thinking of the QS 1000w for my next build. Does anyone know the weight of the 1000w? I can't find it. If you're getting 16kw from the 3000 I'm thinking I can get 5kw from the 1000. These motors are so long I've been thinking hard how to fit them between my pedals.
