Frame Size

What Bike Frame Size Do I Need?

At Netherlands Secondhand Bikes, we want every ride to feel comfortable, safe and enjoyable. Choosing the correct frame size plays an important role in achieving the right riding position. A bike that is too small or too large can place unnecessary strain on your back, neck, shoulders or knees.

Use the frame size charts below as a practical guide to help you choose a bike that suits your height.

How Is Bike Frame Size Measured?

Bicycle frame size is measured in centimetres. The measurement is generally taken from the centre of the bottom bracket to the top of the seat tube.

Choosing a suitable frame size can help provide:

  • A more comfortable riding position
  • Better control while cycling
  • Easier mounting and dismounting
  • Less strain on your back, neck and knees
  • A more efficient and enjoyable ride

Between Two Frame Sizes?

If your height falls between two recommended sizes, your preferred riding style can help you decide.

Choose the smaller frame if you prefer:

  • More control over the bike
  • A slightly sportier riding position
  • Easier mounting and dismounting

Choose the larger frame if you prefer:

  • More riding comfort
  • A more relaxed seating position
  • Greater comfort on longer journeys

How Do I Measure My Height?

  1. Stand upright with your back against a wall
  2. Wear flat shoes or measure without shoes
  3. Measure from the floor to the top of your head
  4. Compare your measurement with the charts above

Frequently Asked Questions

Does Bike Frame Size Really Matter?

Yes. Riding a bike with an unsuitable frame size can reduce comfort and may place unnecessary strain on different parts of your body.

Can I Use the Same Frame Size for Every Bike?

Not necessarily. Electric bikes, transport bikes and sportier bicycle models can have different geometries and riding positions, even when the stated frame size is similar.

What If I Am Exactly Between Two Sizes?

Your riding preference can help you choose:
More sporty and agile = smaller frame
More relaxed and comfortable = larger frame

Can the Saddle Still Be Adjusted?

Yes. The saddle and handlebars can usually be adjusted further to improve your riding position and overall comfort.

Please note: The measurements above are intended as general guidelines. Body proportions, inside leg length, bicycle geometry and personal preference can all influence the ideal frame size.
