Riders power bicycles over roads, tracks, or trails in races that can last minutes or weeks. That family of sports is cycling. It combines endurance, tactics, and technical bike-handling skill.

Road racing, track cycling, mountain biking, cyclocross, and BMX each impose different demands. Road events may cover hundreds of kilometers and feature complex team tactics. Track racing emphasizes raw speed and precise positioning on the banked oval. Off-road disciplines add terrain management and bike control.

Training balances aerobic capacity, threshold power, and recovery. Equipment—frames, wheels, gearing—receives intense attention because small gains matter. Safety equipment and road awareness are non-negotiable. Cycling’s accessibility also makes it a popular recreational and transport activity beyond pure competition.

The bicycle remains one of the most efficient machines humans have created for moving under their own power.
