Biketrials riding techniques Pivoting 90° on the front wheel
In this technique, you should already know how to turn 90° on the front wheel and also how to hop on the front wheel.

Sometime useful for better positioning, but mostly to show off.
1° Move your body slightly off-centered, towards the fall by twisting the waist. 2° Carry on turning on the front wheel, with the back wheel well lifted in the air. 3° In one hop on the front wheel, eject yourself from the wall and carry on the twist.
While pivoting on the front wheel, to 90°, keep the rear wheel well above the horizontal, until you have decided to push-up on the front wheel to carry on the twist. Else, with the rear wheel too low, the front wheel tends to stick to the edge and you 're up for a crash on your back. See the move in a video

A stylish way to come down
Landing smooth?
In the air, pull the bars towards your chest to stabilise the bike in front of you. Let the back wheel hit the ground first, with the rear brakes "on" to gain extra damping power with the "bottom bracket-to-rear-hub" lever. Use the spring of your legs to absorb most of the impact, then lowering naturally the font wheel to the ground by extending the arms. Here again, fat low pressure tires are more comfortable.
