There are 3 main things that will get you out of most situations in cycling. These are true for road and Especially for Mt. bikers!
1) The Track Stand. Being able to stop the momentum of the bike and maintain balance, and being able to start momentum again with out putting a foot down.
2) the Wheelie. Being able to raise the front wheel to get over the oncoming obstacle.
3) The Bunny Hop. Being able to simultaneously raise BOTH wheels at the same time to go over an oncoming obstacle.
For road racers, I would add, the Bump. This is where you touch or bump another rider. This IS going to happen if you race in ‘mass start’ events, or do group rides, so it is better to get used to it, rather than attempt to avoid and Fear it.
So practice these three/four movements while waiting on your riding buddies to expand your riding abilities!!
