[electro wrks]

You got some nice articles there, would you be able to tell me if a 400W AC motor would be powerful enough for an electric motorcycle?

It's pretty big compared to what I've see in other e-motorcycles, but those have different types of motors at higher powers.

Also, unfortunately I can't register to your forum and I don't want to bother your admins just for one question.

Thank you for your forum though!

You either made a typo or need to do a lot more study on this subject.

400W is ~1/2 HP. That's barely enough to power an electric bicycle. I suggest you read the NuWiki and FAQ shown on the title bar above, for basic information.
