Electric Bike Speed Booster

[Nikson420]

Hello Folks just want to hear your opinion. I bought 750 w motor and it s very nice. Silent and powerful. If you have 20 degrees hills it s perfect. If you want on mountain, you better buy 1500 w. Maximum speed it's around 40 km/h. How to increase my speed even more? With this kit I got around 5kmh - Check here - https://s.click.aliexpress.com/e/_ADzqk3
Any suggestions guys? Thanks.

Not sure about that link, could be possible spam post with only 1 post.
More speed is either you put a dc-dc booster to boost the voltage or you increase the battery voltage, I dont think amps increases much speed maybe by a hair.

Yeah might be spam since he’s asking a question about the 750w, then suggesting the 1500w for the mountains. Sounds like advertising

20 degrees incline is 36.4% grade, slightly steeper than the steepest paved roads in the world.

Increase voltage to over a hundred volts and a new controller.
Chalo he was talking about downhill.

I'd be more suspicious of the web link, click.alibaba gives it an air of legitimacy but having click in the link, I just dont know.

Has anyone clicked on it, is it legit alibaba going to the OP's alibaba homepage selling 1500w motors?

There is nothing in the post that specifies direction. Safer to assume uphill, since downhill at those slopes doesn't require any power at all to achieve very high speeds, if the downhill is long enough.

what I meant there's no way of 500 w 750 watt or 1000 watt motor is going to climb at 36 degree Hill up hill

maybe by itself.

Sure the post is spam.

About the speed anyway, this is not about your comment or about you my friend, it is just that I keep reading around this forum about increasing voltage or current for more speed. Of course, voltage and current play an important role in performance, but when it comes to non-natural limitations, remember that these hub brushless motors really are three-phase motors. Then, frequency is really the key for more speed, or at least to achieve the maximum possible natural speed for your motor/controller/battery combination. Nothing else.
