Resumen

The YT Industries Jeffsy is a highly versatile trail bike that excels in both climbing and descending, offering a fun and agile ride. Its updated frame features internal storage and a sorted component package, making it a great value for the price.

Pros
  • Excellent ride-anywhere bike

  • Updated frame with internal storage

  • Sorted component package

  • Rides lighter than its actual weight

  • Versatile for both rowdy trail sessions and long days in the saddle

Cons
  • Matte black carbon finish is easily scratched and scuffed

  • Lacks stability at high speeds

  • SRAM SX Eagle drivetrain required regular adjustment

The JEFFSY turns every trail into a round of Wild Mouse. No other bike in the test is this much fun.

The YT Jeffsy Mk3 Core 4 is a capable all-mountain bike which, thanks to its spec, has a bias towards descending but is equally able to climb.

YT Industries Jeffsy Mk3 Core 4 mountain bike review

jul 2024

The YT Jeffsy Mk3 Core 4 is a capable all-mountain bike which, thanks to its spec, has a bias towards descending but is equally able to climb. While the spec is hard to argue with and the value for money is excellent, it's worth paying attention to the frame sizing and geometry to get the ride you want. The bike could be improved further with a longer dropper post and a slacker head angle but YT has done a good job continuing to polish the already excellent Jeffsy.
