Gasbike is some Iranian guys that sell chinese knockoffs. It's capitalism, but also blatant plagiarism.
I ordered my frame from gasbike. It took a little longer than expected for shipping. I tried calling their customer service line and never got in touch with anyone. It eventually showed up, but I was on the verge of filing a PayPal claim.
Anyway, the knockoff frame i got seems like it's good quality. The pedestal mount is holding up after a year of abuse, so that's something. Keep in mind that the frame is quite large. The pedestal helps space it up and back more.
Check out this thread for tips. I had no clue what I was doing, so I figured it would be beneficial to others in the same shoes.
