How to build dirt jumps (bmx/hard tail)

Find a Good Location - This should include large open space, try to find golden coloured dirt which will compact really well. Slightly downhill is better so it is easier to maintain appropriate speed.

Where to Dig Your Dirt Pits - Make sure to dig right in the middle of the jump so there are no pits next to the up ramps and down ramps. It is a good way of economising space.

Ready to Break Ground - Make sure that you have a steep hill to pedal up to speed and than start your first jump. Use a wheelbarrow to make huge piles of dirt. Pack it down as you pile it up.

Starting Your Second Pile of Dirt - This should be nice and steep and transition to a smooth landing. The steepness of the landing depends of the size of your lip on your take off. Compact it again.

Shaping Your Jumps - Make sure your lip is roughly 2 - 3 ft wide and the landing 3 - 5 ft. DON'T build rhino horns! Pay attention to the curve of the jump itself. Your take off should be smooth.

Knowing What Your Building - If there are any retaining walls, make sure you build them solidly. If you're aiming for length in air your take off should be a 40 degree angle.

Format Of Your Jumps - It's a good idea to make different styled jumps. You could have a Flat Double, Step Up, Step Down and a Tabletop. The tabletop is usually the best jump for length.

Resist Jumping It The First Day - There needs to be good rain followed by some very hard compacting. If you don't compact your jumps well you will not have a smooth landing or take off.

Cementing Your Jumps - Cementing your jumps would be a great idea, it will improve the flow through the jumps and it help you not to have to face, bumps on the up ramp of your jumps!
