Basic bike riding skills

A bicycle riding skills, basic


(a) posture


Correct posture is: the teaching of cycling, low head slightly sloping forward, Arms bent down to the waist, natural bow down, reduce the body weight, and prevent and car jolted due to force. Hands light and powerfully wrap, hip sit tight seats.


(2) the stirrup


Cycling of the stirrup methods have freestyle, toes down and heel down 3 kinds.


1 and freestyle stirrup method: at present, some outstanding athletes are mostly adopts the stirrup freestyle. This method, the stirrup is in the process of rotating feet in a week, according to the different parts with changing ankle angles. Freestyle stirrup, accord with principles of mechanics, the direction of rotation and pedal formed circumference tangent consistent, reduced the knee and thigh action is helpful to improve the amplitude, frequency, stirrup naturally through critical area, reduce the blocking zone. A thigh muscle also can get relative to relax. But this method is more difficult to grasp the stirrup.


2, toes down the stirrup method: its stirrup is in the whole process of the stirrup spin down, this is her ankle range, small method is helpful to improve the frequency, easy to master, but the leg muscles always is in nervous condition, against nature through critical area.


3, heels down type stirrup method: heel downwards stirrup type is slightly upward and downward tiptoe heel 8-15 degrees, this method is rarely used in normal riding in just a few people in riding process for excessive use of force to adjust when heel downwards stirrup type. It is characteristic of the muscle in short time change, hard to restore short rest, muscle fatigue.


Second, turning skills


(a) : a car is inclined to bend, incline.


1, based on the car body gravity to bend inclined, people in the same car maintain Angle.


2, the knee unbend of lateral and subconscious overtime, like you to put your feet trample down like (but if you really beat him down don't find us).


3, with a knee medial beam, this is an adjustment of the track you good method, reduce stress can narrow locks.


4 and lateral hand pull a handlebar.


Using the two good timing tilt:


Can use the curve is not less than 45 degrees) (accelerated


You can clearly see front but not familiar with the bend


Wet asphalt road, tilted two defects:


On a rainy day, although the turning skills can give you a good traction, but it's Angle and the weight of the distribution and arrangement not conducive to wet road, No corresponding inclined skills more sensitive to reverse.


(2) : the car to the upright position within the body, to bend inclined.


1, move, until the nose and brake into line.


2 and keep the car body bent to erect, within the lateral enough to tilt (arm unbend)


3, a CeWai handlebar to bend.


4 and the arm elbow bend inside and outside also handlebar back to turn out the arm handlebar handlebar direction.


5 and keep both knees buckled, continue in cadence.


Third, the bicycle ride downhill


Downhill rides on the road cycling technique is an important basic techniques.


(a) uphill riding technology


To maintain the normal uphill riding the stirrup action, not sudden force, in the ordinary circumstances, unfavorable use standing type riding bike or tiras type method, otherwise you'll be excessive consumption. Meet them short, should make full use of the motion inertia principle, easily and quickly to the coping of the stirrup can be used when the speed of riding, stand, to improve speed possible downhill to create favorable conditions. Meet the long, according to their physical condition adjusted ratio, don't wait on motionless and speed completely change ratio, lowered to resolutely to avoid to start the phenomenon to appear. What a long or a steep, can alternate stand, adjust pin type parts, let part muscle forcibly rested.


The uphill with not too near. Due to the reasons, driving up with cars, often swinging too close, may collide. Furthermore, the uphill speed significant decline, the car will make himself with the method of riding restrictions.


(2) ride downhill


Downhill rides to achieve the ideal effect, be brave to wit, brave talk, concentrate, two eyes close watch of the road ahead, ready to appear on the surface treatment of the determination of any situation, Not only should make full use of the car, and motion inertia glide to active the stirrup, increasing speed.


Turning to the body, and to maintain consistent, in his car, and keep a straight line, the centrifugal force to overcome. According to the speed and bend Angle, but generally size shall not exceed 28 degrees, otherwise have slipped.
Before turning to control the speed. With the gradual deceleration, brake method, and at the same time, the gate as far as possible, a former gates ahead before using the front gate, direction and the direction of the car is consistent, otherwise, the meeting because of the rider, weight, and restricted to the inertia of wrestling. After the corner gate will go, lest cause unnecessary. After using the corner gate don't too. Otherwise, the car could turn or slip.


Four, brake technique


Before you can provide very good braking force, but also can let you become frequent flyers, below we tell you how to brake.


(a) before using it will focus back


When you use the brake, you before the inertia and natural gravity will forward, you must practice when you start braking, consciously will you move backward (body low, bottom back). Focus back, the more you can use more brake force.


You can be in the sand or a bit wet flat floor exercises, speed, using different force under the pressure of you before and after the brakes, know how to control your brakes. Or ask ace when riding in the use of how he brakes.


(2) before turning to reduce power of brake


And in turn to drive a car, you must reduce speed. If you turn on the hard ground when you brake, you will lose control of sideslip produced. When used at the same time in the corner of your before and after the brakes to reduce your speed. When your front brakes will reduce the response, so reduce the braking power before you turn will be more perfect.
If you are in a downhill, need to use the hairpin, try to use the power of the rear brake. As in the last minute, flat on the front to reduce weight back behind 30% of brake force, 70% for brake.


(3) not excessive pressure before brake


"The inertia is your friend," you need to go through the rocks and the speed of obstacles. Otherwise, the wheels would stop turning into your hand will have. Excessive pressure before you can make checks, and under the car.


If you turn on the steep slope before use, then you must also brake control of your brakes and not overly has been forcibly, when you can according to a press release a braking action to prevent locking brakes phenomenon.


Five, mountain bike skills -- simple techniques make you more like the professional rider


Riding a bike with you family and children, shower in the suburb of nature, enjoy the trip. One or two things may be around you: or in the procession, mountain bike you hungry want out something to eat, but when you go hand in hand bicycle is easy to fall, Do you want a drink of water, you are like a far from you to get, When you watch rear, don't worry about that, through our after these tips, as long as a little practice, you will be very skillful, seem to be born and ability.


1, why? If possible, find a flat, or is slightly downhill road, the road uneven (not a good time to handle loosened, don't stop pedaling), and keep looking at you, not the hands, one elbow, holding hands slightly curved. Elbow slightly bend can absorb shock of stone pavement, and stable in any effect when you drink the movement direction of mountain, another hand down the kettle, then, also can't see below but keep looking ahead, so constantly practice repeatedly, until the very skilled. If your canteen is small, reached down, to grasp it, if the cap is large, then hold the bottle of bottle of local, the water in the kettle to corners, lest side cover. With teeth unplug caps, after drinking, using your body to shut up, then bottle closures smooth land back on the shelf, still cannot look down, keep straight ahead. If this recruit, let's take a bottle, or try not to use a water system, as long as a straw in the mouth.


2, looking back, you can leave the hand hand, should pay attention to the road ahead, when you look back from left shoulder twist, will you hand to relax, the elbow, although slightly bend your upper body torsion, still can keep the direction of straight, mountain, if you ride very fast, you can also quickly from your left arm down quickly check below. If you need to compare long time to check, then you must sit is near, right at vertical tube, and then go left the tap, present a body torsional look back on, a professional skills: when you ride with another man, when you go back, sitting up and touched you ride with the shoulder, this will help you ride a straight line.


3 and if you intend to ride a bike more than a hour above, it is necessary to some pockets of clothing made by natural food can enhance physical block food, of course, you may use both hands to eat a meal, you can only eat the food that simple packaging. In the anterior, you shall tear of packaging are some, such as you eat the unnecessary expend setbacks. While these food placed, the best is very easy to get the sack and not mixed together with the map of the deep pockets, take up very convenient. When you're ready to dine, body, and a sitting beside hand vertical tube elbow part, leading to reduced shaking slightly curved, then took food and tore down your earlier part of tear down, then can eat. Remember, eat and do not lose skin, should be put in the bag.


4 and the wavering rider in groups of riding is dangerous, even individual solo in a crowded, also can endanger others when. If you are not sure of his ride a straight line, so you should be in the white paint line along the line to practice. But if you can relax and upper arm, the simple exercise is almost impossible, so must be relaxed. Will you hold hands light slightly curved handle, elbows, about 30 feet on the vision, but don't focus on line, as long as you know in this line, and soon you will find himself very stable.
