BIRDY Mk3
New Classic BIRDY
Main differences:
1. Frame: New Classic BIRDY has round tube frame, same as the Mk1 BIRDY, but of course many improvements compared with the Mk1 model. The New Classic BIRDY was introduced in 2014 as a special edition for BIRDY's 20th anniversary. New BIRDY (Mk2/3) has monocoque frame which looks more aesthetic, but of course more expensive than classic model.
2. Price: In Asia (especially Taiwan) many users consider the New Classic BIRDY as entry level model, so if you don't have much budget then New Classic BIRDY would be the best choice.
3. Specs: I think you can find it all on Pacific website.
I happen to have both models (actually New Classic for my wife T^T) and I have to say the New Classic is a very very good deal!!
