6. Learn the Wheelies
Wheelies and nose wheelies (having the back wheel off the ground) are fun little tricks, and they are quite useful on the trail.
You can pull a little wheelie to get your front wheel up and over an object, and then shift to a nose wheelie so your back wheel doesn't hit. Even if you can't get either wheel off of the ground, knowing how to take your weight off them will make some sections of trail smoother. These are easier to do with clipless pedals, but less intimidating to learn with platform pedals.
Starting with one pedal up and one down, a basic wheelie is a combination of pulling up on the handlebars, shifting your weight over the back wheel and pushing down on the up pedal. You can just do it for half of a pedal rotation, or try to maintain the wheelie and keep pedaling. Either way, keep your hand ready to pull the rear brake if you are going too far back; grabbing it will get your front wheel down.
The nose wheelie is a little different. You definitely don't want to do this if there is something in the trail that is going to stop your front wheel, and you don't want to grab your front brake. Either one will toss you. In one motion, lean a little forward, push forward on the bars and pull up with your feet. Even if you are using platform pedals, you can hook your feet and still lift the back of the bike up.
Hopping and balancing skills really pay off when riding technical trails. Having the ability to come to a stop and then start again without putting a foot down makes it easier to keep your momentum.
These are both done while standing still, though you can lunge with the bike while you are hopping to go up and over stuff (stairs, rocks, people, etc). Pure stationary balancing—also called a track stand—is done without holding on to the brakes. To learn this, practice going as slow as possible and feathering your brakes to cut your speed. It is easiest to learn this on a slight uphill slant. Soon you'll be able to balance without going anywhere by shifting your weight and moving the bike beneath you.
Hopping is sort of the same concept but done with both brakes locked while you pick up both wheels to keep the bike underneath you. With your body centered between the two wheels, compress your body, then push down to raise your body up and then pull up with your arms and legs. It takes practice, but it will soon become easy and useful.
The little tricks may seem silly, but they do help develop overall bike-handling skills.
8. Take a Brake
Actually take two brakes. Better braking will allow for better bike control. Many new riders think they only have two brake settings, locked and not in use. You've actually got less control with the brakes locked, much like a car.
Learn how to use both brakes effectively. Most of your braking power comes from the front brake. But be careful not to use it too much if you are going downhill or cornering. You'll either get tossed over the bars, or your front wheel will slide out. It is all about moderation and modulation.
When cornering, practice braking before the turn, rather than in the middle of it. You'll soon be able to carry more speed through the turns. When descending, learn to feather the brakes so that they don't lock up. If they do lock up, ease up a bit. You'll not only have more control, but you'll save the trail from excessive erosion.
9. Go Yonder
Once you've mastered your local trails, venture forth into the world and explore new ones. New trails and challenges will make it more exciting to be riding, and they'll help sharpen your skills. This is the key to becoming a well-rounded rider.
10. Ride Everywhere
The more time that you spend on your bike, the better you will get. Ride to the mailbox, to the store, to the coffee shop. This will help to reinforce your riding skills as you ride up and down curbs, dodge potholes and outpace angry chihuahuas. Once you can easily ride down two or three stairs, you can approach trail obstacles with a little more confidence.
You can read about cycling as much as you want, but nothing replaces saddle time. So with that in mind, put this down, gear up and get out and ride. I'll see you on the trail.
