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.

Method #4: Ask Your Dealers
