Hi there, I bought a Birdy on Craigslist a couple years ago and just got around to making a few humble mods.. Was going for a comfortable very upright ride so added a stem extender to the already made for comfort stem. Changed out the seven speed grift shifter to a trigger. Changed the saddle to a wider one to go with the very upright riding position. Reliving how fun making mods are from back in the bike commuter days ..
