Today, bicycle manufacturers offer their products in a huge assortment for outdoor enthusiasts. Among them, a separate niche is occupied by two-suspended models, which stand out for their design features.
Features and purpose
The design of bicycles of this kind is quite in demand. Full suspension is a classification of bicycles based on the number of suspensions on it.

Among the notable features of bicycles with two shock absorbers, it is worth highlighting their high cost, since during the time of use, such structures have managed to establish themselves as professional and high-quality devices for riding and sports. However, among the available range of double suspensions today, you can also find more affordable models that are unlikely to be used in professional sports. but for skiing in special conditions, different from urban ones, they will come in handy.

The extra shock is placed at the back, which makes the full suspension different from a regular bike. Now manufacturers divide the line of such products into two categories.The first includes professional-type products designed for sports and movement on difficult sections of the race track. Sports models of the second group belong to the mass production of bicycles that are more suitable for the city and for use on walks, but taking into account the choice of a mountain riding style.

Advantages and disadvantages

- Such designs stand out for their high operating comfort. It has been established that in the process of movement such a bicycle is able to soften shocks and vibrations that negatively affect the cyclist's spine. This moment will allow the person to get tired less, stay productive longer and operate the device with greater comfort.
- Moving on a two-suspension bike on the descent, a person has the opportunity to give his legs at least a minimal respite by relaxing the muscles. This will be relevant for long and difficult races. On such a bike, the second suspension will be responsible for the shock absorption at the rear.

How to choose?

- The primary task when choosing folding or monolithic models will be to determine the main tasks that a double suspension should cope with. For city riding, simpler designs can be considered, which will not be additionally equipped with reinforced tires and all kinds of accessories for professional sports, which will significantly affect the cost of production.
- When choosing a bicycle for sporting achievements, it is worth considering models specifically from the discipline where two-wheel weight will be used in the future. This will help you find a truly worthwhile model that will cope with the tasks.
- A folding frame will only be needed for those varieties that will not be used to the limit of their capabilities, since it is this part of the structure that will be the weakest in the overall chain.
- As for the choice of material from which the frame will be made, it is most correct to choose from an assortment of aluminum or composite options that are capable of long-term operation with increased load in comparison with the steel components of the bicycle.
- Also, the study of the reliability of fixing the rear suspension deserves special attention. All components must be tightly fixed, without unnecessary hesitation and gaps.
- It is also important to determine how the available speed range will suit the selected riding style.
- The type of brakes is another nuance that needs to be dealt with in advance. Disc brakes can be used for some disciplines, but hydraulic drive is more practical.
