How to Build BMX Dirt Jumps
Jumps make BMXing more fun and add challenge to your trails. You don't have to be an expert engineer to make dirt bike jumps, but you do need to be willing to spend some time and energy to make the dirt jumps right.

1
Plan your course. Know the starting point and plan enough pits between jumps so you can maintain or build additional speed before hitting the next jump. Look for spots where you can place a jump between trees or place a double or triple jump.

2
Start with enough room to gain speed before hitting the first jump. Allow room to land by making the area wider and longer when necessary. You may want to give notice for hip jumps that require turning mid-air to land by spray painting an arrow with the direction of the turn on the ground before the jump.

Collect dirt and pile it in the locations for your jumps. The average dirt bike jump is 4 feet tall, but a variety of sizes makes the course more challenging. Take the dirt from the pit areas as you smooth them down or from areas you won't use for your course.

Shape the dirt piles into berms, or mounded piles. Use a flat shovel to pack the dirt down. Make sure you don't have any flat spots, rocks or twigs that could trip up riders.

Water down your jumps and allow them to dry. The water compresses the dirt and packs it into place. You may need to add dirt, repack and water down again if flat spots occur or the jumps don't look right to you.
