Proficiency Levels

Brand new riders!. The novice class can be raced on any size bike. Novice is not separated by boys or girls. When you start racing BMX everyone starts at the same level! Classes will be separated by age group.
After the rider wins 10 races as a novice, you move up to the intermediate class. In the intermediate class a 20” bike is required to race.
Expert/Girl Expert
After 10 wins (for girls in novice) or 20 wins (for boys as an intermediate) the rider moves up to Expert/Girl Expert. At the expert level, boys and girls will race separately in their own class and age group.
Cruiser/Girl Cruiser
This is a class for 24” cruiser bikes. Boys and Girls will race separately in their own class and there is no separation in proficiency. A rider can race both in a novice/intermediate/expert class and a cruiser class as long as they have a bike to race in both classes.

Balance Bikes

Balance Bike is an open, non-pointed class formed with riders age 5 & under riding push bicycles without pedals. This class will form with 2 or more riders. On occasion, if the need arises, Balance Bike may be offered to riders over the age of 5 with special needs.

Balance Bike Riders race for free, excluding multi-point races.

An annual Balance Bike membership is $30.
