Ive had some good reliable bikes with chinese engines. It really comes down to what factory / manufacture makes them. Lifan seems pretty solid, and ive had some luck with Zongshens. Not all chinese engines are built the same.
I dont mind the bike but the seat looks un-comfy and the small fenders look pointless. Price tag seems a bit steep too - might as well consider a Honda rebel or Kawasaki Ninja for that cost.
