It is better to choose V brake or disc brake for children s bicycles

Children's cars must be V brakes, children's cars are different from adult cars, you must not use the idea of adult cars to consider children's cars, in principle, at the age of 12 and below, do not use disc brakes.

Because it is too easy to lock, the child will fly out from the front or side after braking, especially when braking suddenly, the probability of flying out is higher, and the cost of disc brakes is high, and it is much more difficult to repair than V brakes, if brake pads.

Presence of sand or brake pad gaskets.

It's not clean, and it's too cumbersome to deal with.

At the same time, when braking control, the V brake is easier to flexibly control the tightness, even if it is pinched, it will not lock the stop, which is very important for the safety of the child. Decathlon.

For example, the 599 V brake is relatively safer for children, and for the 1399 disc brake fork shock absorption recommended by the shopping guide, the latter can be said to be no good for children, after all, children are not playing stunts, forks for children, riding a lot of deflection at the same time, but also let children tend to take bumpy roads or steps, which virtually increases the risk of children riding. For the 599 car, ** is quite reasonable, but the quality of the tire is not proper, not a high-pressure tire, and at the same time, in order to facilitate installation, the seat adopts a quick-release structure, and for children, do not let them adjust the seat height by themselves, because this will greatly increase the risk of driving.

I bought a Giant.

BMX of the 998.

Riding for children, expensive is a little more expensive, and 599 Decathlon bicycle compared with me I also feel distressed, but Giant is designed and considered from the perspective of children's cycling, which is better than Decathlon adding too many useless functions at the same time, with a bunch of second-rate or first-class but low-end accessories of the model is much better, the key is that the safety people have thought about it for you.

The V-brake is easy to maintain and has low cost. If it's a bad disc brake, it's not as good as a V-brake.

Disc brakes can slow down faster on bumpy and steep dirt roads, and you don't have to worry about getting stuck in mud and sand. The frame of the children's bicycle is not suitable for this kind of road surface, without this kind of intense mountain riding environment, too strong braking force is easy to make the children's bicycle lock, there is a danger of sliding or flying out. So try not to buy disc brakes for children.

In addition to the use environment of children's bicycles without disc brakes at all, let's talk about the disadvantages of disc brakes from the structural principle of disc brakes

Disc brake is the use of resin or metal to make the pad and metal brake disc friction, and the hydraulic energy can amplify the characteristics of braking force in a certain proportion, which determines that the response in the initial stage of braking will be better, in the initial section of the brake lever can output a larger braking force, and the end section is also easier to lock the wheel. This is also why the disc brake is easy to lock up during emergency braking, resulting in side slip or tail flicking, for active children, riding a sudden letter shouting Zhaoran slip rental is too common to find that there are obstacles in front of them need emergency braking, at this time it is too dangerous for them to use disc brakes.

How to choose a children's bicycle:

It is necessary to buy a bicycle of the right size according to the age and height of the child, and it is not recommended for children who are too young to ride it, which is very unsafe. It is best to start riding around the age of three, a 14-inch one is suitable for a three-year-old child, and a 16-inch one can be ridden at the age of four or five. Six or seven-year-olds can ride 18 inches.

Do children's bicycles need shock absorption and disc brakes: No, children start to ride balance bikes at the age of 1, 14-inch Qiaoshan children's bicycles at the age of 2, and 16-inch children's bicycles at the age of 4. As a bicycle shop, the shock-absorbing forks of children's finger bikes on the market are basically gimmicks and are of little use, and because of the cost, the shock-absorbing forks of children's bicycles are shock-absorbing, and the effect is negligible.

No, children start to ride the balance bike Pailiang at the age of 1, a 14-inch stroller at the age of 2, and a 16-inch stroller at the age of 4. As a bicycle shop, the current strollers on the market with shock absorption are basically gimmicks, which are not very useful, and because of the cost, the shock absorption forks of the stroller are all shock absorption, and the effect is negligible.

Hello, dear, the car master will serve you, attentively, carefully and attentively answer for you, find the corresponding problem solution and solution for you, and will definitely provide you with a satisfactory answer! We hope you find this answer helpful. Morning Thing .

What is the best brake for a children's bike? I will give you the following answers to this question, then first of all, children's bicycles usually have micro-business and disc brakes, these two braking methods are more common, although the performance of disc brakes will be better, but it is recommended that young children choose micro-business, because micro-business is a tire, and both sides are braked with rubber diggers. Longfor plays the role of a brake, and this brake structure is relatively simple.

The structure of the disc brake is that the brake pads are embedded in the hub and scatter the liquid, so young children may put their hands in it to play, and there is a risk of pinching their fingers at that time.

Hello, the disc brake is good, the heat dissipation is fast, and it is not afraid of water, and the effect will be reduced after encountering water.

PS: (1) Disc brakes are composed of a brake disc connected to the wheel and a brake caliper on the edge of the disc. When braking, the high-pressure brake fluid pushes the brake pad to clamp the brake disc to produce a braking effect. (pictured).

The advantages are:The action is sensitive, the heat dissipation is good, there is no need to adjust the brake clearance, and the maintenance is easy.

2) The principle of bicycle braking is to fix a wheel or disc on the high-speed shaft of the car, install the corresponding brake shoe, belt or disc on the machine base, and make it produce braking torque under the action of external force. The brake device is a mechanical braking device that can slow down the speed of the vehicle, also known as a reducer.

Commuter cars can choose disc brakes and V-brakes, and the brakes are secondary.

Advantages of disc brake: 1. The heat dissipation is better than that of drum brakes, and it will not cause brake recession and brake failure when continuously stepping on the brakes.

2. The change in the size of the brake disc after being heated does not increase the stroke of pressing the brake pedal.

3. The disc brake system responds quickly and can do high-frequency braking actions, so it is more in line with the needs of ABS system.

4. Disc brakes do not have the automatic braking effect of drum brakes, so the braking force of the left and right wheels is relatively average.

5. Due to the better drainage of the brake disc, it can reduce the situation of poor brakes caused by water or sediment.

6. The structure of the disc brake is simple and easy to maintain.

Advantages of V brake: 1. Light weight.

2. Simple structure, easy to install, maintain and repair.

3. Low cost and high cost performance.

4. The maintenance cost is relatively low.

Holding brakes: Holding brakes is a braking method used in the past, and now it is slowly used less.
