If you want a BMX that feels right from day one, start with the size that actually fits your height.

A good size gives you control and confidence. It also makes learning tricks easier and more fun. In our store you will find BMX bikes for kids, beginners and riders who already know what they want.

If this is your first freestyle bike, size matters more than colour or brand. A wrong fit can make the bike feel heavy and hard to control. The right one feels natural from the first ride.

How do I choose the right BMX size?

The simplest way is to match the rider’s height with the recommended wheel and frame size. Forget age charts, height is what really works. Check the BMX size chart below and pick the range that fits you. No guessing needed.

Based on RMDBike’s experience and sales data from thousands of BMX bikes fitted for riders of different ages and heights.

Still not sure which BMX size is right for your child?

If you are unsure about the size, contact us by email or phone and we will help you match the right BMX to the rider’s height and style of riding.

Key info before you start riding your BMX bike

A BMX bike is built for spins, jumps and landings which means every session puts stress on the frame, fork and wheels. These bikes are strong but not indestructible. Regular checks and basic maintenance help keep your setup safe and ready for riding.

Before you hop on your new BMX remember

• Read the user manual and warranty to understand the rules that apply to freestyle bikes.
• Bikes ordered online come mostly assembled for safe transport. You attach the pedals, handlebars and sometimes the front wheel.
• The manufacturer recommends a first service check also called zero service at a certified bike workshop. This keeps the warranty valid.
• Keep the service receipt because it is required for warranty confirmation.

Take care of your BMX and it will stay ready for many sessions full of progress and good energy.
