Pedal-up

Roll at the wall like you mean it. Focus on where you wanna land. Bad foot at about the 12 o'clock position.

As you get nearer the wall, start pedalling hard, whilst crouching down over the bars, ready to spring up.

As you pull up and your good foot comes round to the top of the stroke, start really throwing your body up, and lifting the bars up hard with your arms.

Extend your body vertically, meaning you can suck the bike up underneath you higher. Just spring up super hard, whilst still pulling the bars hard.

Throw the bars forwards once the front's cleared the wall fully, and bring the back of the bike up with your hips, knees and ankles. Just suck it up

That should do it, really...
