Summary

The Trek Farley fatbike series is praised for its versatility across seasons, offering a mountain bike-like feel with impressive rear suspension and stability. It excels in mixed conditions, from packed snowy trails to summer singletrack, though some models face criticism for ponderous handling and underperforming forks. The Farley's design blurs the line between fat bikes and traditional mountain bikes, providing a unique ride experience.

Pros
  • Impressive rear suspension

  • Versatile four-season capability

  • Stable and fun on various terrains

  • Lightweight for a full-suspension fat bike

  • Modern riding position and balanced shape

Cons
  • Ponderous fat bike handling

  • Bluto fork underperforms in aggressive riding

  • Heavy compared to traditional trail bikes

  • Tires not ideal for deep snow or loose terrain

There is no reason for an offseason with a bike like this.

Trek Farley EX 9.8 review

Jun 2017 · Russell Eich

The most mountain bike feeling fat bike yet. Buy if you want one bike for all seasons, or an extremely stable trail bike, and aren't concerned about pure dry trail performance

Highs
  • Impressive rear suspension, has a very mountain bike feeling, wheelies and manuals with ease

Lows
  • Bluto fork overworked, small tire knobs, busted rear rim
