Summary

The Niner WFO is a versatile and playful downhill bike that excels in big terrain with its impressive suspension travel and efficiency. It's praised for its ability to handle high-speed descents and tight turns, offering a stable yet poppy ride. While it's more of a 'play bike' than a race-focused machine, its comfort and climbing capabilities make it a strong all-rounder.

Pros
  • Massive amount of suspension travel (180mm front, 170mm back)

  • Really, really poppy, more so than any bike with this much travel

  • Excellent resistance to harsh bottom outs

  • Versatile long-travel machine

  • Comfortable pedaling position

Cons
  • Poor 'high' BB position geometry and kinematics

  • 2.6-inch Tire spec is not for everyone

  • Felt dull and lacked pop in bump jumps and jibs

  • Actual seat angle could be steeper

Key Quotes
The Niner is really, really poppy. Far more so than any bike with this much travel has any right to be.
Jeff Kendall-Weed logoJeff Kendall-Weed
The WFO falls on the friendly side of the long travel category, a bike that could work well for riders who want plenty of travel without paying too much of a penalty when it comes time to pedal.

WFO stands for 'Wide Full Open,' and that is exactly where this bike is happiest.
