Tips for mountain biking How to change gears I m 18 speed

First of all, congratulations on your new car!!

The basis of your question, I will also be the basis).

18-speed mountain bike.

There are 3 gears in the bottom bracket and 6 gears in the rear wheel, and the 18 is matched by the change of the position of these 9 gears of the chain, that is, 18 gears. The larger the gear, the faster the speed and the more laborious it is for the bottom shaft. The gears of the rear wheels, the smaller the gears, the faster and the more laborious they are.

So when the chain position is in the front pinion and the rear pinion, it is the most relaxed, but the speed is very slow. This combination is suitable for climbing steep slopes. When the chain is positioned in front of the big gear and the rear pinion, it is the fastest, but also the most strenuous and suitable for high-speed riding on flat roads or downhills.

You can frame the bike, twist the shifts while turning the pedals, and see the direction of movement of the chain to see how it twists faster and with less effort.

To protect the chain and gears from excessive friction, avoid the variable speed mode of big gear to big gear or small gear to small pinion.

Do your own research and you'll understand.

Mountain biking tips include:

1.Shifting before going uphill: When going uphill, you'll need to choose a smaller front gear and a larger rear gear to help push the cart uphill with ease. Put the front gear in the smallest position and then the rear gear in the middle or maximum position to provide enough torque and power.

2.Flat road shifting: On flat surfaces, adjust according to the riding needs and physical condition. Place the front gear in the middle or larger position, and then the rear gear in the middle or smaller position.

3.Downhill Adjustment: When going downhill, a larger front gear and a smaller rear gear need to be selected to provide more speed and better control. Put the front gear in the largest position and then the rear gear in the smallest position.

4.Shift gears evenly: Don't change gears when accelerating sharply, as this can cause the vehicle to lose control.

5.In special cases, if the gear cannot be in place when decelerating uphill, you can slow down the tread a little, and you can generally change the speed smoothly.

The above are some tips for mountain biking, I hope it will help you.

Mountain bike. If the speed change is regular, it is necessary to follow the principle of "big in front and small in the back, small in front and big in the back". 1.

The front 3 and the rear 7 of the flat road are the fastest (the crankset is the largest, the flywheel is the smallest), and the first 2 rear and the gear are usually more suitable for riding speed in the city. 2.Uphill front 1 rear 1 is the most labor-saving (the crankset is the smallest, the flywheel is the largest), usually the front 1 rear gear is more suitable when climbing.

3.3 before and after downhill, can be (according to the situation of the speed change, downhill crankset can not be on the small chainring, flywheel can not be on the large chainring, in order to avoid the danger of kicking) generally left front dial right rear dial, transmission.

The larger the value on the higher the speed ratio, that is to say, the larger the value of the left hand, the larger the gear of the crankset, the larger the value of the right hand, the smaller the gear of the flywheel, at this time, the front is large and the back is small, the speed is the fastest, and the reverse is the most labor-saving. Note: The front and rear transmissions should not be changed at the same time, it will be bad for the transmission, and do not change the speed after stopping, make sure that the rear wheel rotates before changing the speed, otherwise it will also hurt the transmission.

The front is large and the back is small, and the front is small and the back is larger, but the pedaling frequency is higher, and it will be very laborious for a long time. The correct way to change the speed is: the flywheel (that is, the rear disc) starts at the time of the first time, and changes to the small disc as the speed accelerates, so that it is both labor-saving and fast.

If the crankset (that is, the front disk) is a three-piece type, the rear disk can not be hung into the most ** when the front disk is hung into the most **, on the contrary, when the current disk is hung into the smallest disk, the rear disk can not be hung into the smallest disk, and the front disk is in the middle of the disk when the rear disk is arbitrary. When using the flat road, the front is large and the back is small, if the front is small, the back will be very tired and slow; When going uphill, use the front small and the back large, because the front is large and the back is small, not only will it be tired, but it will not be able to pedal when encountering a steep slope, and at the same time increase the burden on the transmission system. In general, the downhill slope should be large in the front and small in the back.

1. First of all, we need to briefly get to know the bicycle. The left handlebar of the bike is the front shift control center, and the right handle is the rear shift control center. There are buttons on the handle to adjust the gear, and the gear can also be displayed on the handlebar.

2. The gears of the front gear from top to bottom are high-end (3 gears), middle gears (2 gears), and low gears (1 gear). The rear gears are from bottom to top from low to high (from 1st to 7th). Generally speaking, the higher the gear, the faster and the harder it is to pedal.

The lower the gear, the slower and easier it is to pedal.

3. When we ride on the uphill road, in order to save effort, we should adjust the front gear to 1 gear, the rear gear to the gear (the rear gear can be adjusted according to their actual situation and the size of the slope).

4. When we ride on a flat road, we should adjust the front gear to 2nd gear and the rear gear to 4th gear. Of course, the rear gear can be adjusted according to your actual situation, and the gear can be adjusted.

5. When we are driving on a downhill road, we should adjust the front gear to 3rd gear and the rear gear to the gear position.

6. When riding on the downhill road, since the front and rear gears have been adjusted to the highest gear, we should strictly control the speed to avoid traffic accidents.

For general riding, the front gear can be left unmoved and placed on a larger gear.

After: First of all, if you ride a bicycle and find that your feet have to be very hard to step on, without too much external intervention, such as wind, terrain, etc. That's the gear error. With the right gear shift, you should never feel any excessive drag. Whether it's fast or slow.

The principle of variable speed is to accelerate first, many people want to speed up, just put the gear on one, in fact, the correct way is to speed up the frequency first, climb a few laps, feel that the foot can not keep up with the pedal, you can change gears. Analogy.

When encountering difficult roads or headwinds, you should pay attention to the difference with the car, such as a dirt bag, if the car can't go up in third gear, you can stop in place to change the second gear, first gear, and the bicycle does not have this function, you must judge in advance, change the low gear before the car arrives, that is, the rear big gear, if necessary, the front gear should be smaller. This is because the bike can only change gears if it is boarded. In the same way, before the crossroads, you should also downshift in advance and change the rear cogion, one is to reduce the speed, and the other is to improve the sensitivity.

In addition, acceleration shifts should be shifted in one gear except for high cadence and rapid acceleration, and deceleration can be across several gears at a time.

At first, it seemed that I had to think about it, and it became a habit to ride for a while.

Here's what I pasted.

I lived for 19 years

I haven't been able to ride a bike. Stuffy.
