Please don't take this as coming from a "know it all" BUT.
WARNING
Important note to new bike owners. (Not just Chinese bikes but all bikes)
PUT THE BIKE TOGETHER AS DELIVERED, RIDE IT FOR A WHILE, AND CHECK IT OUT COMPLETELY BEFORE STARTING MODIFICATIONS.
MAKE SURE EVERYTHING WORKS.
DON'T OVER TORQUE FASTENERS.
DO ONE MOD AT A TIME. CHECK YOUR WORK BEFORE CONTINUING.
Several people here have made a lot of mods without even riding the bike as stock and the mods had to be backed off in order to trouble shoot the problems. This happened big time to a guy with a Qlink XF200 and he started bad mouthing the bike immediately. All the problems were user caused.
