I have a Flamingo from Taiwan which takes many of the same parts as Brompton (UK). This call goes out to owners of either bicycles to review the shops that cater to the world's premium folding bike and its copies (MIT etc).

Perhaps there is one shop that is better at English fluency, another at selection of products, yet another at repairs, etc

You can find a list of most of the bike shops and what they carry here: www.bicyclethailand.com
