Baotian
Huatian
Geely
'MotorZeta' (OEM)
'Jetstar' (OEM)
And many more OEM brands.
The problem with chinese scooters is that :
-they're sold for inflated prices. Many distributors/retailers just want to make a quick buck and sell them for around or over €1000 which is way too much considering the questionable quality of many chinese brands.
-they lack a service network.
-distributors are unreliable and can disappear anytime.
There's room for 1 or 2 brands if you set up a decent service network, keep prices attractive and please stick to the original brand name. There are too many of these motor/star/jet brands around.
And most important: get a quality brand, preferably Baotian (already taken, sorry
)!
