A mix of two worlds — the speed of a 29” front wheel and the agility of a 27.5” rear. The Bluebird Intro Mullet in Sand Storm matt finish is a full-suspension trail bike for riders who value control, flow, and fun on every ride.
The Bluebird Intro Mullet is Dartmoor’s first full-suspension bike with a mixed wheel setup — 29” at the front for better rollover and stability, and 27.5” at the rear for playful handling and quick direction changes. It’s a modern trail bike that strikes the perfect balance between efficiency and capability.
Equipped with 130 mm of travel front and rear, handled by X-Fusion MIG Air 34 RC and O2 Pro R suspension, it ensures smooth and confident performance on varied terrain. The Shimano CUES U6000 1x10 drivetrain offers reliability and crisp shifting, while Shimano MT-201 hydraulic brakes with 180 mm rotors deliver predictable stopping power.
A wide Tornado Low handlebar paired with a short Viper stem keeps the steering sharp and stable, while the tubeless-ready Raptor rims with 30 mm internal width enhance grip and comfort. Wrapped in a light yet strong aluminium 6061-T6 frame finished in Sand Storm matt, this bike is ready for long trail days and weekend adventures alike.
Ideal for riders looking for their first full-suspension bike — easy to control, fun to ride, and fully equipped to handle any trail.
