Sweet bike!
Thanks!
Very very cool
Thanks!
I think you could try and add a cvt to this as you have a bit of space. Would make this bike very fast.
That would be cool! Top speed would increase alot
yoooo thats sickkkk broo! ive been thinking of building something like this! do you have a 0-60 time?
Thanks! At the current gearing top speed is only little over 50kmh. But with taller gearing it would go 80-100kmh. But I like torque more than top speed so thats good gearing for me
@@pajajaska oh cool
Nice built I’m thinking of building a minibike with QS 90.
How old are you in? What country do you live in?
@@Emaster.85 Thanks. qs90 is good motor for small bikes. I recommend you to have good battery and controller so you can get all potential of that motor. I live in Finland and im 21. what about you?
@@pajajaska I am 17 and I live in Denmark. I have build a CR 85 with a qs 138 70h v1 20s 14p and bac8000 it’s a freaking death trap
Can the qs90 run 3000watt continuous? I have one but im worried about overheating.
I have been running it with 10kW for while and I still havent burned it. Of course it overheats pretty fast if I ride full throttle on soft sand. You need to test the motor by hand that its not overheating too much. And I think that having low gearing helps that it does not heat up so fast. I have top speed only little over 50kmh. But 3000w for this motor should not be a problem
@@pajajaska this motor is insanely cheap for the performance from what I've gathered
@@je7647 yea its really good motor for little bikes like this.
I just put a QS90 on an old moped (Crescent 1175 frame), running it on BMW E330 60v packs paired with a Fardriver ND72360 and man are these motors performing above expectations! Even with 19" wheels and 14:60 gearing it'll occasionally loose grip on asphalt when punching it.. Hardly gets warm when riding like a somewhat sane person, would recommend limiting peak output to around 7kW to keep it healty. I agree with @pajajaska1222 , 3kW continous is not an issue, it stays luke warm at that output.
WHAT IS THE AVERAGE PRICE for an qs 90 ?
I don't know average price, but I bought mine for 215€
@@pajajaska thanks where do you have bug this motor ?
