Looks pretty good, although I have heard of Ciniworx I'm unsure what their after sales service is like. And for the same price you could get a Motovert, Pitster or Terra Moto which are the big names in Chinese bikes.
ive herad some great things bout ciniworx, ive seen em in person and a few of my brothers mates have em, and race them (grasstrack) from what I hear there pretty good, but havent become a popular brand yet.
down at the anzac day FITTY races at frankston bike track, 1/2 the bikes there were either Ciniworx The other half was motovert. My mate has had a ciniworx for 2 years now.. Good strong reliable bikes.. thats if your just planning to muck around on them.. Although i have no idea on how'd they would hold up on jumps though..
nice bike not so sure about that frame tho. I just not sure if the bike worth that much mate, sure the bike look all blingky yet those are just eye candies think if you really up to some high end bike then try Motovert or Pitsterpro x4 or x4r.
