Which Bike Fits You? Complete Size Chart

How To Find Your Perfect Bike Size

Choosing the right bike size is essential for comfort, safety, and performance. Here’s how you can easily determine your optimal fit:

  1. Measure Your Inseam: Stand against a wall with shoes on, feet apart. Place a book between your legs as a saddle would, and measure from the floor to the top of the book spine—this is your inseam length.
  2. Check Height & Age: Match your inseam and height to the chart below. Age is a useful guide, but height/inseam always matter most.
  3. Review Features: Features like training wheels, gears, and brake types are listed for each bike size.
