2018 Trek Farley EX 8

Jan 2018

The Farley EX doesn't need your snow or your sand- but it'll handle it just fine - while being a dirt and rock shredder with little compromise...

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
