Building
Trails
Planning
Jumps | Phase One
| Phase Two | Final
Preparation
Being part of a crew who built
a set of good jumps is very rewarding and in my opinion is one of the
best parts about BMX. Although the trails will be rewarding when they
are done they take a lot of work, I mean days sometimes weeks so don't
think that you and a few of your friends are going to take picks and
shovels and build a boss set of jumps in a few hours. So now that I
warned you that its going to entail a lot of work, lets get started...
Plan
your jumps
Okay... so you and some of your
friends had the brilliant idea to build some jumps out in the woods
but first you need to gather tools and plan out where your jumps are
going to be and what natural obstacles you want to incorporate in to
them. You want your trails to flow or you won't have enough speed to
catch the next jump. Also you want to take trees into consideration
If there are two trees that you think are impeding your building, build
a jump between them. You also want to take jump size into consideration.
Large jumps are only for the skilled and can take hours to create only
one. If you are a good BMXer and have the time and patience you should
make your jumps 5-6 feet high, if
you are intermediate 3-4 feet high and if you are a beginner about 2
feet high.
Phase One
Now that you have a plan and the materials
you need you can begin building. The most frequently encountered jump
in the BMX world is the double jump. A double jump consists of your
launch ramp and your landing ramp. All double jumps obviously have a
gap, don't make the gap too big for you to clear. To build a double
jump you will need to pile up 2 mounds of dirt, one for the launch one
for the landing. The mounds should be about a foot taller than your
desired jump height.
Phase Two
Now that you have your two mounds of dirt
in front of you it's time for the difficult part. This is kind of hard
to describe. But you want a launch jump that has a transition similar
to a ramp. So it needs to be nice and smooth curving upwards toward
vertical. They need to be pretty steep. This is a bit annoying at first
but it is the best way to get the amount of air you need to do tricks.
In a way it is actually safer. So what you need to do now is to start
shaping you jumps into a nice curve. So get a shovel with a flat head
and start smoothing it down the face of the mound of dirt you just piled.
Once you have something that looks good, you need to start packing it
down. Use whatever to pack the dirt. Like your feet or bikes or your
shovels. When finished, it should be as hard as cement. OK so now you
should have your launch jump sorted out. Now you need to shape your
landing jump. This is a little bit easier. You just need to make it
so it has a lot less transition than the launch one. Make it nice and
wide so when you catch sketchy air you have a good amount of space to
land on and not get mangled in your bike. Pack this down well too. It
doesn't have to be quite as hard as the launch one. Now that this process
is done you are ready for final preparation.
Final Preparation.
It is always hard to
not just start riding when you have packed down and shaped your jumps.
But it is important to make them rock hard. Otherwise you grove them
and they will fall apart really quick. The secret to making hard jumps
is water. You need to get a hose and spray them down. If you can't get
a hose to them then you will have to wait till it rains or carry buckets
of water to the trails. Just keep packing them down and eventually they
will be as solid as cement.
Remember, don't ride them wet! You will ruin the shape of them.
