The YT Jeffsy 29 Core 3 is a very capable all-mountain bike which can handle the rough stuff but is equally at home on flow trails and jumps. While the specification list is solid for the money, it's worth paying extra attention to frame sizing and geometry to get the ride you want. With a longer dropper and some tougher tyres this bike has what it takes to be a real challenger when it comes to the best mountain bikes.

Like Robocop or the Six Million Dollar Man, YT have rebuilt the Jeffsy with top notch tech to be (even) better than it was before
Superbly capable
Wants to blast every trail
Packed with top tech
Instant freehub engagement
App driven suspension setup
A hefty investment
Slightly conservative geometry
May 2022 · Ed Thomsett
An excellent complete package that makes fun of all but the gnarliest descents, thanks to a head angle that feels too steep
Predictable ride quality
A solid suite of parts
Great for riding just about any terrain
Conservative head angle
A good price, but the outrageous value YT’s reputation was built on isn’t there

A great value with an appetite for rowdier trails. .
Incredibly capable
Incredibly fun
Incredibly versatile
Incredible value
Pedal bob had us using the lockout on long climbs
Slightly limited water bottle space
Could use stronger brakes

Whether you’re 5ft 1in or 6ft 4in tall, you won’t have any issues achieving a glove-like fit on the YT Industries Jeffsy Core 2.
Great suspension & handling
Pricey given the spec
