Method #3: Bike Size Calculator 


If you are a fan of maths, then this step is for you! 

If you are not (just like me) then just give it a try, it isn’t that hard 🙂

  • Stand with your legs apart (15cm – 20cm). Make sure that you have taken off your shoes.
  • Measure your leg inseam, that is, the length of your leg from your crotch to heel.

Take your calculator and calculate!

  • Hybrid bikes: Leg inseam (cm) x 0.685 = Your frame size (cm)
  • Mountain bikes: Leg inseam (cm) x 0.685 = Your frame size (cm)
  • Road bikes: Leg inseam (cm) x 0.70 = Your frame size (cm)

Note: For example, if your looking for a hybrid bike and your inseam length is 70cm, then your bike size would be 70 x 0.685 = 49cm.

I told you, this wasn’t that hard.
