Curious if anyone has any experience with these. They caught my eye when poking around at cheap metal full suspension frames with room in the triangle. I can't find much info on the frame itself, but the same brand of forks seem to be fondly spoken of with respect to budget options.

I want full suspension for an ebike build. My current hard tail rides a bit rough over bumps when I'm at speed. So I'm on the hunt for a sub $600 frame that is not carbon fiber
