What size of road bike should I ride?

What size road bike should I ride? There are some "do by yourself" methods to discover your bike size. Have in mind that they will give you a standard idea of what to buy, but a professional for final adjustments is always recommended. Method one: Your height / Bike Size Method Two: Calculating the bike size Take off your shoes; stand with your legs far about 15-20 cm(6” – 8”) from each other; measure the height from the ground to your crotch. Have in mind what model of bike you do want: Mountain bike, city bike, gravel bike, or road bike. Calculate the right size according to the bike you had chosen: 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
