Zero AM

The Zero AM is a trail smashing, berm destroying hooligan of a bike. It’s a hardcore hardtail that will go anywhere you dare; Enduro racing, all day trail centre trips or collecting air miles at the freeride park.

  • 150mm or 160mm front suspension
  • Super short chainstays for a playful ride
  • Aggressive hardcore hardtail with 64.1 degrees static HA (160mm fork)
  • 27.5″ x 2.8″ tyre clearance
  • Boosted Bird chainstay yoke that runs boost or non boost cranks depending on chainring size (30t or below will run non boost)
  • One piece machined brake mount and dropout assembly for maximum precision and minimum squeal
  • ISCG05 chain guide mount
  • Bottle cage mounts
  • External cable routing for easy maintenance
  • Continuous outer gear cables for maximum cable longevity
  • BSA threaded 73mm bottom bracket
  • Tapered ZS44/ZS56 headset
  • Stealth dropper seatpost routing


The classic Bird Raw finish. Brushed aluminium with a gloss finish.


Two contrasting blues make this frame stand out from the masses.

The perfect neutral colour for accessorising with shiny anodised parts.

When updating the Zero AM I wanted to retain as much of the original character of the bike as possible.  This new version features more tyre clearance, even more generous top tubes and a slacker head angle. It’s my go to bike for aggressive riding on local trails.
