I have yet to read about anyone here or chinariders owning the t-rex. There are a couple videos on youtube, including one by skyteam usa, and some from Europe and the UK, but that is it. I have tried to search for any videos by pitster on their sherpa, but nothing comes up.

Roketa only sells wholesale, but I would guess someone sells Roketa in Hawaii and could order one for you. They seem like a great bike for the islands. The entrepeneur in me sees a Hawaiian rental business for them, as well as some other bikes...
