I actually think R&M is not solidly invested in the Birdy like it was in the 1990s and 2000s. Spares are difficult to find outside Asia [especially for mk1s, and now aftermarket companies in Sing. and Japan and Taiwan have more than R&M] , prices are still high, the company is big on electric bikes, and I heard about the shift to more electrics in an interview online with either R or M, forget which.
Pacific Cycles, meanwhile, are innovating strongly and close to the main markets in Asia.
And do not forget that the Philippine company Rhine got the moulds to make Mark 1 Birdys, [they used their own name on them] and did a decent product - not sure they are still going, but I guess that was a license agreement.
I have often wondered why so many Birdy classics are branded as Peugeot in Asia. I have one from 1996 branded as 'Jeep', bought form California, but Pacific and R&M shut that down pretty quickly.
There are people from Pacific Cycles on the BGF on Facebook that could answer these questions. I believe PC are still not allowed to sell frames separately, or rear swingarms or forks.
