... on the front wheel Move around, or clear the rear wheel from a tricky zone in biketrials while repositioning, by rolling on the front wheel.

Getting on the front wheel (endo)
1° Moving at a slow pace, just apply full brakes on the front wheel.	2° Carry on moving your body forward until your weight is above the stem.	3° Pushing on the handlebars while folding the knees will lift the back wheel.
Once you master the endo, you don't need to be moving to do it. You can just shift your weight forward while braking, to end up on the front wheel. Then if you are in a slope, just release the brakes to roll on. See the move in a video or the full move until return to initial position

Clearing the rear wheel

What is it good for? It is really useful in real trials, either to reposition the rear wheel from one spot to another, turning on the front wheel, or to clear the rear wheel away from a gnarly section, by smoothly rolling on the front wheel until the rear tire gets some grip on a safer section. Or any combinations of both. This helps for turning around, either going down or in a straight horizontal moves, or even climbing while avoiding early rear wheel contact.

Climbing with a small endo while turning at the same time.

How to do it At the beginning, don't go too fast or you'll go over the bars (remember, it's about balance, not about crash speed). If things go really wrong, do not release the front brakes (too unpredictable) or you'll eat (hit) the ground. Instead, jump off the bike while holding the handlebars. If you are in a slope, release the front brakes slightly to ride down on the front wheel, in full balance above the stem.
