YT gives a leg up to the next generation of shredders with its impressive Jeffsy Primus.

Pros
  1. Looks fantastic. Kid-optimised attention to detail. Suspension actually works. They’ll love shredding the downhills…
Cons
  1. …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

Pros
  1. Fun and nimble
  2. Solid and reliable spec
  3. Overall offering from YT gets you going straight from the box
Cons
  1. Dropper post needs to have more drop
  2. Value for money maybe isn't as killer as YT's of old - just being picky
  3. Consider upsizing if you're looking for stability over playfulness

An excellent complete package that makes fun of all but the gnarliest descents, thanks to a head angle that feels too steep

Pros
  1. Predictable ride quality
  2. a solid suite of parts
  3. great for riding just about any terrain
Cons
  1. Conservative head angle
  2. a good price, but the outrageous value YT’s reputation was built on isn’t there
