Get more traction, more grip, more float and more confidence. The Bad Habit 1 bike takes the fun-loving nature of the Habit and supersizes it with 27+ wheels to create an all-new trail crusher.


  • 27+ wheels blend the performance and speed of a 29er, the simple aesthetics of 26 in. wheels and the cushioning of a fat bike tire
  • Short chainstays, ample clearance and dialed geometry deliver uncompromised performance for maximum fun
  • The Lefty fork use a longer 55mm fork rake to reduce trail and keep the handling snappy even with a bigger tire diameter
  • Clean, internal routing through the seat tube makes it easy to upgrade to a dropper post
  • Asymmetric Integration offsets the rear triangle and drivetrain 6mm to the right for clearance on 3 in. tires, dual chainring compatibility and a stronger, stiffer rear wheel
  • WTB Bridger 27.5 x 3 in. tires offer the float and traction of fat tires without sacrificing control or maneuverability of narrower mountain bike tires
  • Shimano Deore hydraulic disc brakes provide powerful deceleration
  • Pedals sold separately
  • Specs and images are subject to change
