Bicycle frame size calculator
Bicycle type:
Mountain bikes are designed to use on rough terrain cross country roads, forest paths, and mountain or rock areas. These bikes usually have strong frames, thick, rough tread tires, shock absorbing damping systems while driving on rough roads (as well as a greater distance between the earth and the central axis, which increases wheel traction).
There are three different types of mountain bikes: rigid (called Full rigid), Hard-tail with suspension front fork, and full suspension. Mountain bikes come in different wheel sizes: 26 ", 27.5" and 29 ", but for all these bicycles the frame size is chosen according to rider height and leg length.
Road bikes are designed to ride on paved road surfaces, such as streets or bicycle paths. The main features of their low weight, good aerodynamics, narrow tires and curved handlebar, which gives the rider the opportunity to ride especially aerodynamic position.
Road bikes are mainly used for racing, touring rides, long journeys, city community and etc. Road bike frame size is measured according to the rider's height and leg length.
All terrain bicycles ATB includes the city, touring, trekking and hybrid type bikes. City type bikes are designed to ride in the city and often have not so much gears and are equipped with carriers, front and rear lights or reflectors. Touring- trekking bikes is slightly longer than the city-type bikes, but the seating is not severely bent. Perfect for long journeys.
These bikes have more gears and are equipped with racks and front and rear lamps or reflectors. Hybrid bikes are a type of mountain bike and trekking bike mixes. They come with front suspension forks, no racks or other additional items that do not interfere with maneuvering forests or mountainous areas.
The geometry of the bike is similar to the Trekking type of bike geometry, but they often come with a shorter rear chain stays. These bikes usually come with 28 "wheels and is equipped with a medium hardness width of tires, so that would be a good off-road traction and fast ride on hard or paved surfaces. All terrain type bike frame size is selected according to the rider's height and leg length.
BMX bikes are two types Race, and freestyle. Racing BMX bikes are extremely lightweight for speed and stability, and freestyle BMX bikes for maneuvering, bouncing and tricks.
BMX bicycles typical - small, very sturdy frame and light weight, very wide, has an additional footrest, steering arched top. The most common wheel design allows the front wheel to rotate around 360 °. Wheel size - 20 "or 24". BMX frame size is determined in accordance with rider height.
Kids bikes are small, sturdy frame and thick tires and specially designed for children. They are perfect for travel flat, paved or hard surfaces. As the child is bigger the size of bicycle wheels needs bigger. This is the main criteria for determining the wheel size.
The simplest is a bike without pedals have small wheels and rides resisting feet. The bikes are larger wheels, while they are usually equipped with features that educate child's skills, coordination and confidence. This calculator will help you determine what size bike wheels should fit the child's height.

Recommended size:
As the bikes come in different geometries as well as people of different physiological properties rely solely on the frame size recommendations should not be, they are for guidance only. You should always sit on the bike and try it if it is convenient and appropriate for you.
Mountain bike frame is measured from by the frame seat-tube. The measurement from the central of bottom bracket to the frame end where the seat post is inserted.
Road bike frame is measured from by the frame seat-tube. The measurement from the central of bottom bracket to the frame tube end where the seat post is inserted. Some manufacturers measures bicycles by top tube length, so be careful, because these recommendations is based on effective seat-tube length.
ATB and hybrid type bicycle frame is measured from by the frame seat-tube. The measurement from the central of bottom bracket to the frame end where the seat post is inserted.
BMX bicycle frame is measured by the top frame tube length, measured from the seat tube to the center of the steering column tube center.
Wheel size measures with an inflated tire diameter. Wheel size is usually written on the sidewall of the tire.
