Two Wheeling Tots
Trailcraft Blue Sky - 20" Kids Mountain Bike Review

Jun 2023 · Carrie Wren

Exceptional components and feather-weight build make the Trailcraft Blue Sky 20 an ideal tool for growing the skills of your budding shredder!

Highs
  • Lightest 20-inch MTB on the market at 19.0 lb (Pro build)

  • Exceptional components: Shimano Saint clutch derailleur, Deore brakes, SLX shifter

  • Tubeless ready rims and tires, option to ship ready with tubeless valves

  • Highly customizable: chainring size (28T/30T), two build levels, frame-up customization

  • Five bright color options, more than any competitor

  • Water bottle eyelets above down tube (unique for 20 inch)

  • Excellent derailleur ground clearance (4.25 inches)

  • Lock-on grips with small diameter for small hands

  • Short-reach brake levers sized for one-finger braking

  • Included pedals (VP composite with metal pins) are trailworthy

Lows
  • Lower stack and handlebar height may not suit all riders as they grow

  • Flat bars have essentially no rise; handlebar height not adjustable further without swapping bars

  • Seat height minimum is 24.4 inches, ~1.5 inches higher than some competitors

  • Higher bottom bracket and longer crank arms may create tight knee bend for shortest riders

  • Components may vary based on availability; confirm before ordering

  • Dropper post not recommended for most kids on a 20 inch bike

  • QR skewer axles instead of thru axles (to save weight)

  • Need careful water bottle selection due to limited frame space
