Two-suspension bicycles: characteristics, varieties, brands, choice
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

Initially, such models were produced for operation in extreme conditions, where it will be important to have two wheels adhesion to the ground, which is provided by the presence of another shock absorber.
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 two-suspension bike stands out from the rest of the structures with the following characteristics:
- structural strength;
- small mass;
- the ability to develop good speed even in non-standard conditions.
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.
