How to choose a bike according to your physiological parameters

When choosing a city bike, mountain bike, road bike, children's or BMX bike, you need to follow the old common truth: measure seven times - cut once. But trying on and cutting off with the help of our article will become extremely simple for you.

Only in a circus does a perky uncle on an awkward bicycle look appropriate. Outside the walls of an entertainment establishment, the pedaling "bear" looks at least strange. God bless him, with the opinion of others, riding the wrong bike is simply fraught with health problems.

When shopping for your first or new two-wheeled friend, be sure to select the correct size model for your anthropometric data.

City bike

The city bike recommendations are based on measuring your leg length.

To determine the size of the inseam (I), take off your shoes, stand against the wall and take the book. Simulate a saddle by pressing the book firmly against the crotch with the spine up. Have someone measure the distance from the floor to the spine of the book.

The length of the seat tube (ST) is taken from the center of the crank (or BB) to its edge. Pipe size is usually measured in centimeters.

Inseam, cm	Seat tube, cm	Crank, mm	The size
64	43	165	XXS
65	44	165	XXS
66	45	165	XXS
67	46	165	XXS
69	47	165	XS
70	47	165	XS

BMX bike

Recommendations for choosing a bike for competition motocross are based on measurements of height.

Your height (H) can be easily determined with a book and a measuring tape. Take off your shoes and headgear, stand against the wall. Place the book on your head and draw (scribble) a small line under the book. Measure the distance from the floor to the notch.

Top tube length (TT) is calculated from the center of the seat tube to the center of the head tube. Pipe size is usually measured in inches.

122	15, 0	150
124	15, 0–15, 5	150-155

Children bicycle

The recommendations for choosing a child's bike are based on the age and height of the child.

The child's height (H) can be easily determined using a book and a measuring tape. Remove your child's shoes and hats and place them against the wall. Place the book on your child's head and draw (scribble) a small line under the book. Measure the distance from the floor to the notch.

The bike is matched to the outer diameter (D) of the front tire. Wheel diameter is usually measured in inches.

Height, cm	Age, years	Wheel diameter, d.
85–110	2–5	Runbike
85–100	2–4	12
95–110	3–5	14
