I have made a lot of people happy repairing their no name Chinese bikes. But like Vegan theres a bit of pick and choose where an unsafe bike that cannot be made safe wont get repairs. Most of the time its something silly and simple. But if its not, it becomes way more difficult, like a really nice scooter I cant get a throttle for despite numerous messages to the manufacturer AND replies. There is often a horrible communication gap.
Id it has a name and someone to ask questions to, a Chinese product may be OK, but if you want to keep riding, stick with a real brand.
