The trials mountain bike is a bicycle specially designed for practicing the discipline of trials, which consists of overcoming natural or artificial obstacles using balance, precision and technique rather than speed. Here is a description of its function and characteristics:

Function :

1. Crossing obstacles:

The main function of a trials mountain bike is to allow the rider to overcome obstacles such as rocks, tree trunks, low walls or stairs using jumping, balancing and precise maneuvering techniques.

2. Maneuverability and agility:

Trial mountain bikes are designed to provide maximum maneuverability and agility, allowing the rider to execute fast and precise movements to overcome the most difficult obstacles.

Features :

1. Frame:

Trial mountain bike frames are generally more compact and more robust than those of traditional mountain bikes. They are often made of aluminum or steel to provide high impact resistance and increased durability.

2. Geometry:

Trial mountain bike geometry is specifically designed to maximize maneuverability and agility. They typically have steeper head angles, shorter chainstays and lower bottom bracket heights to improve responsiveness and stability in trials situations.

3. Wheel size:

Trial mountain bikes can be equipped with wheels of different sizes, generally 20 inches for the most common models. Smaller wheels provide better maneuverability and make technical movements easier.

4. Tires:

Trial mountain bike tires are often inflated to a very low pressure to provide maximum grip and better shock absorption when crossing obstacles. They also have a special tread designed for optimal traction on rocky or uneven surfaces.

5. Brakes:

Trial mountain bikes are often equipped with hydraulic disc brakes to provide precise and powerful braking control, which is essential for mastering technical descents and jumps.
In summary, trial mountain bikes are bicycles specially designed for practicing the discipline of trials, which emphasizes overcoming obstacles using balance, precision and technique. With their specific geometry, their robustness and their adapted components, these bikes offer optimal performance in the most demanding situations encountered during trials.
