Learning the tabletop is about sequence: secure table jumps, tilt the bike, small lean, early return. 5 stages with milestones, mistakes and clear safety rules.
The honest answer first: in a tabletop you lay the bike flat sideways in the air so that it looks like a table top, and straighten it again in good time before landing. Sequence decides success: secure table jumps first, then tilt the bike, then a tiny lean, then build up. There is no association or study description of the technique itself that we have read. The execution notes below are scene practice and carry no source number.
What it builds on is documented. BASPO recommends a small table a few metres long for practising jumps; in the air arms and legs stay only slightly bent and the centre of mass central [1]. And every jump element depends on a controlled flight phase: neither front nor rear wheel may sag [2].
Why is the tabletop risky? Because the return to a straight landing position happens in the air. In the video analysis of 534 crashes, 64.4 percent of over-the-bars crashes followed poor jump landings [3], and a fall during a jump doubled the odds of head impact (odds ratio 2.2) [4].
How hard is it? It belongs to the pro skills (experience-based: months to years), and it is unnecessary as long as you do not jump securely.
In a tabletop it is not how flat the bike lies that counts, but when it stands straight again.
Ten clean landings, eyes to the landing, body tension in the air [1].
Milestone: ten out of ten clean, both wheels land together or the front wheel slightly earlier.
Roll on the lawn and tilt the bike alternately left and right, your upper body stays calm (see bike-body separation) (practice).
Milestone: 20 degrees to each side, head stays in the middle.
On the small table you tilt the bike only a few degrees sideways, so little that it looks as if nothing happened. You straighten it early (practice).
Milestone: five mini tabletops in which the bike is straight at landing.
Note the moment from which you bring the bike back. The earlier you bring it back, the more reserve you have (practice). Change only this one variable, not speed, lean and jump at once [2].
Milestone: on the video you see the return clearly before landing.
Increase the lean only in small steps, on the same jump at constant speed. Stop as soon as the return becomes tight.
Milestone: a clear lean in three of five jumps cleanly, without the landing suffering.
The tabletop is safety-critical. In the bike park study of 274 injured riders, 20.8 percent were due to landings, fractures made up 52 percent, and shoulder and collarbone were most often affected (33.7 percent) (TRANSFER: bike park, not trail) [6]. In mountain biking in general, the head and upper extremity are the most common injury sites [7].
In an analysis of 300 falls, riders used on average a good three recommended protective strategies, most often bracing with the arms (58.3 percent) [8]. That is reaction, not prevention: the best protection remains not riding a jump you do not control. A helmet cut serious head injuries among cyclists by about 60 percent [9] (cycling in general). This guide explains and motivates, it does not replace supervised training or a coach.
Make the tabletop quieter, not bigger. A small, cleanly landed tabletop shows more control than a big one that just about works. The pilot study on ramps shows that experienced riders decide by multiplying fall and injury probability and stop at about 13 percent on average [10]. Make it easy for yourself to stay under that threshold (practice).
If you film, film from the side and from behind. From the side you see the timing of the return, from behind whether the bike lands straight (practice). Compare two jumps in a row: if the second shows clearly more lean than the first, you are increasing too fast.
The bike is laid flat sideways in the air and straightened again before landing. There is no association description of the technique, the notes come from scene practice (practice).
In stages: secure table, tilt the bike on the ground, mini tabletop, timing of the return, lean in small steps. As a practice jump, BASPO names a small table [1].
Enough that you bring the bike back clearly before landing. No source we have read gives a fixed angle. Build up slowly (practice).
Because you still have something to do in the air, namely bring the bike back. Jump landings are a documented risk: 64.4 percent of over-the-bars crashes followed poor landings [3].
