The general principle in a bike trials competition is to ride a number of pre-marked sections (usually 2 laps of 10 sections or 3 laps of 7 sections), the winner being the rider with the fewest points at the end of the competition.

Currently there are two official types of competition rules, enforced by the UCI and BikeTrial International Union.

The maximum number of points that can be obtained in each section is 5, the lowest (and best) score is 0 points or 'clean'. The most common way to gain a point is by putting a foot down within a section; for this reason points are sometimes known as 'dabs'. Certain rules enforce the number of points gained within a section, for example, putting both feet down or a hand will result in 5 points. Exceeding the time limit for the course will either result in 5 points (BIU rules) or an additional point for every 15 seconds over the limit (UCI rules).[UCI

Within UCI rules, if any part of the bike except the tires touch any object in the course, a dab will be given. The UCI rules were changed to this format after too many competitions ended in a draw and riders were forced to ride an extra section. UCI rules also allows riders to compete in both mod and stock categories.

When a rider is in a section, neither tire is allowed to cross the side boundary tape even if the wheel is in the air. The rider's hands must remain on the handlebars.

The UCI Mountain Bike & Trials World Championships are held annually and crown a 20-inch and 26-inch wheel trials world champion.

 BIU

The rules are unlike UCI scoring and parts of the bike (for example, bash guard or bash ring, cranks and pedals) can rest on an object without resulting in a 'dab'. The level of riding for the elite 20″ class is regarded as the highest in bicycle racing since the section beginner is set at the highest technical level[who?].

 Interscolar

The rules are the same as the "BIU" but only people belonging to a club or school can compete in these, these are for lower level students to learn how to compete.
