Finding the perfect fit is critical for comfort and performance. Below, you will find our comprehensive size chart for the Diamondback Kids’ Bikes (20″ Wheel), detailing exact rider heights in feet, inches, and centimeters to help you select the optimal frame.
Diamondback Kids’ Bikes (20″ Wheel) Height Sizing Chart
| Frame Size | Rider Height (Imperial) | Rider Height (Metric) |
|---|---|---|
| One Size | 3’8″ – 4’6″ | 112 cm – 137 cm |
Kids’ Bike Fit Tip: Avoid the temptation to buy a size too large hoping they will “grow into it.” A bike that is too big is difficult to control and can be dangerous. The child must be able to straddle the top tube with both feet flat on the ground.
What to Do if You Are Between Diamondback Sizes?
Stuck between two frame sizes? Because the Diamondback Kids’ Bikes (20″ Wheel) uses specific geometry gaps, riders on the cusp should consider their body proportions (like arm span and inseam) before making a final decision:
Choosing the smaller option gives you a shorter reach to the handlebars, creating a more upright riding position. Opting for the larger frame extends the wheelbase, delivering a highly stable ride at high speeds.
How to Measure Your Height for an Accurate Fit
Finding the perfect frame size requires precision. We highly recommend measuring your current barefoot height rather than guessing. Stand flush against a doorframe, ensure your shoulders are relaxed, and use a tape measure from the floor to the top of your head to get the exact figure. Use a flat-edged object or book resting horizontally on your head to mark the point accurately against the wall before running a tape measure to the floor.
