Trek Precaliber 24 Kids Bike Review

Feb 2024 · Natalie Martins

With or without suspension, the Trek Precaliber 24 offers the cool look of a mountain bike, without the cost of high-end components. Read the review!

Highs
  • High quality frame with clean welds

  • Low center of gravity design

  • Available with or without suspension

  • Suspension is functional for around town but not ridiculously heavy (adds about 1.5 lb.)

  • Two different color options

  • Assembly and tune-ups available at local bike shop

Lows
  • Low-end components (Shimano Tourney, non-branded brakes)
