Bike sizing

Bike sizing is not the most exciting topic to learn about, but it is one of the most crucial.
Having the right bike size is not just a matter of comfort -- it can prevent injury both short and long term, and allows you to have a much better riding experience as a result.
Method One: Calculating the bike size
Take off your shoes and stand with your legs about 15-20 cm(6” – 8”) apart. Measure the height from the ground to your crotch.
Be sure of the type of bicycle you want: Mountain bike, city bike or road bike.
Now you can take your calculator and calculate the right size:                                                                                                           City bike – Leg inseam (cm) x 0,685 = Your frame size
Mountain bike –  Leg inseam (cm) x 0,66 = Your frame size
Road bike – Leg inseam (cm) x 0,70 = Your frame size

 

Method Two: Frame size according to the user’s height
