Cruiser bicycles are measured primarily by the diameter size of the tire. The tire size measurement is most important to determine what size beach cruiser will fit you. Most adult cruiser bikes have 26" tires. Another size consideration is the size of the frame. The frame size is measured from the crank housing to the seat pin. Keep in mind that the seat height, handlebar height, and handlebar angle can all be easily adjusted on a beach cruiser, and there are limits on how much each can be adjusted.

Unlike more technical bikes such as road racing bikes, getting a precise fit on a cruiser is generally not as important, since it is a more relaxed style of bike. It is important to get a bike that fits you well enough so you can pedal comfortable, easily control the handlebars, and ride safely. You don't want to get a cruiser that is either too small or too large. The below sizes give you an approximate height range for each size of cruiser.

• 20" Tire Size
  • 3'2"-4'4" Height Range
  • For Kids
• 24" Tire Size
  • 4'-5'4" Height Range
  • For Taller Kids, Shorter Teenagers, & Shorter Adults
• 26" Tire Size
  • 5'-6'4" Height Range
  • For Teenagers & Adults

This picture illustrates how a cruiser tire diameter size and frame size is measured.
This example shows this is a 26" tire size cruiser with an 18" frame.
