Hooked static hop
The static hop can be performed with the front wheel gripping very narrow edges, even to a point where the bike hangs against the obstacle.
In these situations, because the rear wheel has very little grip, most of the impulse will be concentrated on the front wheel and the fork.
Extreme hooks

In extreme situations (when the obstacle is nearly vertical), you won't be able to secure a confortable position with your torso above the front wheel.
Instead, you will have to hang to the bike and build momentum from a powerful traction on the handlebars to bring your torso over the stem and quickly push up on your arms and legs
to perform the static hop with extra momentum. It is very much like the second step of a regular front-wheel hook, without the run-up distance.
Make sure that your front wheel is well hooked or else it will slip off the obstacle. Before pulling yourself into such a hooked static hop, free your rear brake so as to let the fork flex
a little bit under your weight. The spring effect of the fork will help you pull the bike up once you have completed your impulse.

1° Regroup low behind the bars. Free your rear brake so as to let the fork flex a little bit under your weight.

2° Build momentum from a powerful traction on the handlebars to surge up with your torso over the stem.

3° Follow up with a firm push up on your arms and legs to perform the static hop with this extra momentum.

4° Once your impulse is over, the spring effect of the fork helps you pull the bike up. Tuck your knees to let the bike go.

Placing your front wheel

Typically, because most static hops are performed sideways, the rear wheel lands a few inches aside the initial position of the front wheel.
Landing the rear wheel right in place of the front wheel requires a more frontal approach and more thrust forward during the compression push-up on the handlebars.
Performed at a slight angle inwards rather than purely vertical, the push-up will allow for more forward traction during your jump impulse for a very precise placement of the rear wheel.
