Re: 10kg+ hub motors, too much unsprung weight?

Yeah it’s tough to find the traction with the qs205 sometimes, find it skipping forward on acceleration clear on up to 80mph. It warns you in a hard lean with the stutter as well. But I like it. It’s kind of between a hardtail and a full suspension sometimes, though maybe I just need a more expensiv...

Re: Reputable suppliers of LFP LiFePO4 pouch cells

I just got a 4.4kwh pack of 60ah cells from battery hookup They aren’t very big. They come as 2p 120ah modules. Easy to separate into two cells. Have a 2.5mm thick piece of foam between them, non adhesive.

Around 225wh/kg and cost $115/kWh.. gonna pull 5c should be no problem.

Damn dude. Always use Paypal. Has me covered for 6 months. He owes me support for making his f'd up controller run. Right now I have two controllers from him, both paperweights. And my bike that is just sitting during this beautiful summer thanks to him.

Re: Who knows anything about preventing paint chips?

Not gonna happen. Follow the instructions on the can for painting and clear coating. Then don’t damage it for several months. Paint does get stronger with age but it’s never very strong anyway.

Re: Pricing - 45mph cruise, 60mph top, 50 mile range (cruise speed)

Sadly the range limit is in charging. At random 110v plugs on the streets the most you can pull is about 1000w before blowing a circuit. So for a 50mi range at 45mph cruise you are looking at about 5hrs of 10 miles range of charge per hour. That really sucks. What about level 2 EV charging stations?...

Re: High Voltage high current DC power supply

I haven’t found a 120ac plug that can handle charging at more than 1500W dc. Most times I just do 1000w. I’m using 3x 500w 24v 120ac psus which I once saw go up to 2200w but now I see it is overkill. Used only at home now as it’s too heavy to carry.

Re: QS MOTOR DISK ROTOR HOLE

Use a bolt extractor.

You can also take a nut that will fit over the bolt, weld it in the middle and use a wrench to get it off. The heat from the weld may be enough to break it loose as the aluminum housing will expand more than the steel bolt.

Damn brought a thread from the dead 😐
