Re: High power ebike frame

Why did you fill in your location field with a place you aren't in? You can leave it blank, or put in the correct location. Then the information you get could be more relevant. Or you could just not answer questions i never asked and not be a smart ass. That works too. I was addressing a point you ...

Re: High power ebike frame

You understand that a 20kW bicycle, or a 4kW bicycle, is in fact just as illegal as a motorcycle with no registration or insurance, right? There's no difference in terms of the law.

Re: High power ebike frame

QS273 is rated 4kW, not 20kW. Max continuous current rating is 55A, which is just under 4kW electrical at 72V. Peak current rating is 110A, which is a little less than 8kW electrical but surely throws away much of that power as waste heat. According to this page its a 8000 watt hub. At 100v and 200...

Re: High power ebike frame

Qs273 is a motorcycle motor. you can easily modify a motorcycle frame. 200mm is a standard swingarm size. You’ll just have to figure out the torque arms. I would do that but then i need to license and insure it which means i cant ride it on the road to get at my trails. So yeah not interested in th...
