YT gives a leg up to the next generation of shredders with its impressive Jeffsy Primus.
- Looks fantastic. Kid-optimised attention to detail. Suspension actually works. They’ll love shredding the downhills…
- …but the climbs will be a drag on those fat Minions. Not cheap. Limited gearing range. Might not last a growing kid very long.
Buy if... You want a trail bike that can shred regardless of which way the terrain is pointing
- Fun and nimble
- Solid and reliable spec
- Overall offering from YT gets you going straight from the box
- Dropper post needs to have more drop
- Value for money maybe isn't as killer as YT's of old - just being picky
- Consider upsizing if you're looking for stability over playfulness
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

Following the recent release of YT's Capra and Decoy MX Uncaged 9 builds is the trail-friendly 150mm Jeffsy Uncaged 8.
