A trials bike is a specialized bicycle designed for performing tricks and navigating obstacles without the need for a traditional seat. These bikes are lightweight and feature a unique frame geometry that allows for better balance and maneuverability. The tires are typically wider and have a knobby tread for improved grip on various surfaces, making them ideal for riding on rocky terrain or urban environments. Trials biking is a sport that emphasizes skill and precision, where riders attempt to clear obstacles such as logs, rocks, and steep inclines. Competitions often involve timed courses where participants must demonstrate their ability to maintain balance and control while executing jumps and other technical maneuvers. Popular figures in this sport include riders like Danny MacAskill and Martyn Ashton.
