Keep in mind that Sinnis or Pulse might be manufactured by Pioneer. Pioneer is somehow related to Qingqi, but are different as far as distributorships are concerned. It does seem like Sinnis is the better-made bike based solely on threads I have read here on Mychinamoto, since none of these brands is sold in the US, and our Qlink is a 200cc, with no 125 available (Qlink is Qingqi made). I would take Kennon's .advice .with extra weight as he has been a member here for quite awhile.
