Business in the front, party in the rear. Introducing the first mullet full suspension bike in our lineup. Thanks to mixed wheels (29” front and 27.5" rear), Bluebird Intro Mullet rolls over obstacles smoothly and allow you to take the corner easily and with less effort. We won’t try to convince you about the advantages of such a setup. Just take this bike and you’ll see!

Bluebirds- general info
Bluebird frame uses the same simple but very effective suspension system as the Blackbird but delivers 130mm travel optimized for longer days on the trails. The rear axle spacing is 148x12mm Boost standard and the frame is designed for 210x50mm metric shocks and 27.5" wheels with tire size from  2.3" to 2.8". The advanced swingarm cage equipped with three Max type sealed bearings packed with waterproof Mobil grease and a strong 17mm diameter axle ensures a stiff and strong frame. The higher placed pivot position offers high pedaling efficiency and eliminates pedal-bob when climbing. The low BB position provides high stability in difficult terrain while the 66˚ head tube angle ensures a perfect riding control no matter how steep is the track. Construction using a shock extension yoke makes it possible to keep a full-length seat tube allowing room for the new breed of dropper seat posts.
