When the distance closed to less than three meters, Jonathon braked hard and threw his weight forward, pitching himself onto his front wheel. And just as his rear wheel came up, he activated the hydrojack built into the front fork. He sprang up into the air, tucking into a forward flip. The stadium blurred past above and below him as he spun, and he heard shots over the collective gasp of the crowd. When his natural balance and gymnastic training told him it was time to come out of the tuck, Jonathon arched his back, laying out the final rotation to land again. Two wheels, no wobble.
