How To Choose A Suitable Bike Frame Size?

A proper frame size would bring you more fun and good experience when biking.

You may find different methods to help you choose the frames size which fits your body, by the calculator or by Calculation formula.

Here is our advice for your choosing.

 

Know what is the Bike frame size.

It may be different from the different company.

Some bikes are measured from the centre of the bottom bracket to the very top of the seat tube.

Some bikes are measured instead to the intersection of the centerline of the top tube with the centerline of the seat tube.

Some bikes are measured to the top edge of the top tube, even though the seat tube protrudes higher up.

So when you choose a suitable frame size, you should know how they are measured first!

Here in our company, the frame size means measuring from the centre of the bottom bracket to the top end of the seat tube.
