What are you saying is incorrect? That Chinese scooters need more maintenance? They require valve adjustment every 1000 miles, compared to ten times that interval for Honda or Yamaha engines. Bolts on Chinese scooters shake loose and need to be tightened regularly if the owner doesn't disassemble and reassemble with LocTite. This is more maintenance.

GY6 engine parts, including peripherals, are highly available and dirt cheap. Body plastics aren't available, but could be repaired with standard panel beating techniques. It's true that it's sometimes cheaper to buy a new one. That's primarily because new Chinese bikes are so cheap.

A naive buyer shouldn't imagine his IceBear scooter will give him 100K miles. But he can get 10K miles if he doesn't wreck it in an accident.
