Several of Ed's roads take him across overpasses. Each has deep, 4-inch-wide expansion joints. They're a real pain in the chamois if ridden over, and hitting them at speed could damage wheels.
So, Ed jumps them. It's a technique you can use, too, to get over various hazards that you can't ride around and don't want to slow for.
Here's how:
Practice in a safe place. And use a nonhazardous obstacle, such as a rolled up jacket or towel.
Keep your speed. If you hesitate and then decide to jump, you may not have enough velocity to carry the rear wheel over.
Square up. Always jump in a straight line, not at some angle that could threaten control when you land.
Stop pedaling with your crankarms horizontal.
Crouch with elbows and knees well bent.
Spring up and pull the bike into your body with your arms and legs. You need clipless pedals or snugged toe straps to do this.
Extend your arms slightly to lengthen the bike's flight and set the wheels down smoothly. When you're good, there won't be a thud.
