Key Fit & Safety Tips for Parents

  1. Frame Height = Standover Safety
    Ensure your child can stand over the bike frame with both feet flat. Check your child’s inseam length before selecting.
  2. Adjustable Handlebar Height
    Proper handlebar height supports good posture and easy steering. Sizes 18–20 offer more reach for growing kids.
  3. Measure for Storage
    The full length/height helps you check if the bike fits in your garage, car trunk, or apartment space.

Tip: Add 50mm clearance if storing vertically or on a repair stand.
