Serious up front, party in the back. The Bluebird Intro Mullet is Dartmoor’s first full-suspension bike with mixed wheel sizes — 29” in the front and 27.5” in the rear. Built for riders who crave flow, agility, and the freedom to ride however they like.
The Bluebird Intro Mullet takes the best of both worlds — the speed and stability of a 29er with the playfulness of a 27.5” setup. It’s a versatile trail/all-mountain bike that rolls smoothly through rough terrain and dives into corners with precision.
With 130 mm of front and rear suspension travel provided by X-Fusion components, this bike delivers full control and comfort on descents while staying efficient on climbs. The Shimano CUES U6000 drivetrain offers reliable performance and smooth shifting, while tubeless-ready Raptor rims with 30 mm internal width improve traction and control at lower tire pressures.
The compact Dartmoor Viper stem and wide Tornado Low handlebar give confidence and handling precision on technical trails.
It’s a perfect choice for riders looking for a capable and fun full-suspension machine that’s equally playful and stable.
