New Jialing biker in Shanghai.

[euphonius]

Dear Joker346,

Greetings and welcome to MCM, and welcome to the joys and frustrations of the JH600. Yes, there are several of us who are amassing quite a bit of experience with the bike as well as with the Jialing support community (which is evanescent at best). Are you working with Liu Zhidong and Fan Peisheng?

The problems you are describing with your bike are not ones that I've experienced, and are not on the short list of "things that are problems with the JH600". So it's good that you are raising them now. I'm away from Shanghai for a couple more weeks, but there are five or six of us in Shanghai who are really getting to know the bike well, so don't give up hope. If you bought the bike new, you are under warranty and should fight like hell to get everything sorted. The problems of shifting at speed and vibrations are serious safety issues, and should not be taken lightly. No, you absolutely are not being too picky. The JH600 is a smooth riding bike, and you should address those issues.

I can be a bit more helpful once I'm back.

Bike looks great, and I see you too got the memo about the superiority of black bikes!

cheers!
