Freestyle is an entire genre
of ways to ride a BMX bike
. It's pretty much anything that isn't racing
. This includes flatland
. Freestyle began in the mid 1970s as something that riders
did between races
. From there it grew largely into flatland. From there it expanded to street and trails. Soon after people began riding in empty swimming pools
and vert was born. Park followed soon after.
The term freestyle, while it applies to all forms of riding other than racing, it is more commonly implied to mean only flatland riding.
