Modified Mountain Bike 100, Modified Mountain Bike

The first thing to do is to modify the mountain bike, first of all, to determine whether there is a need for this. Because in the field of sports bikes, the performance of accessories is disproportionate to the end. If you choose a Shimano or SRAM shifting kit, the low-end is basically not an advantage.

Your first question, whether you can install disc brakes, there are two basic points. One is the hub (that is, the shaft of the wire), which is not the disc brake version (this type of hub has six screw ports for fixing the disc brake pads). The second is the hole on the frame to install the disc brake seat, there is no hole and no position, unless you weld it on the frame.

Second, the hydraulic shock absorber, that is, the fork, there is no problem in replacing it. The question is how much price you want to change, generally about 300, it's better not to use it, it's not necessary).

The third shift shifts, and the other depends on the speed of the flywheel. Although Shimano's products are backwards compatible, no one will use a seven-speed rear dial to a five- or six-speed cassette.

To sum up, an ordinary mountain bike wants to be modified on a large scale, and it is still not needed. Let's ride the bike yourself.

1. If you want to change the V-brake, it is enough, because the V-brake needs the support of the bicycle rack.

The direction of the wire seat on the slot frame and the line seat on the V brake are opposite.

And the location is not the same.

If installed, only the front brake can be replaced with a V-brake, because the front brake can be connected to the V-brake directly through the ram.

If you want to change the rear gate, you can only go to the wire soldering seat yourself.

2 is not the rear axle deformed.

It's Taki's problem.

This kind of problem will occur in general civilian tower bases.

It's just a matter of magnitude.

It's almost hard to solve.

Unless you go to buy a better one.

It's not cost-effective. Because it's hard to buy a good spinning tower wheel now.

The big brands don't do the spinning tower wheel anymore.

And civilian spinning has this problem.

In civilian vehicles, this kind of problem is basically not a problem.

3 mind if you use VP

550's. Foot collapse.

It's cheap and it's pretty leathery.

You can buy it for more than 20 yuan.

If you really like bikes.

Mind if you go buy a good car.

Ordinary civilian vehicles.

How do you change it?

No matter how much you maintain it, it is impossible to achieve the effect of a good car.

If it's just commuting.

A simple swap is OK.

To install disc brakes, there must be mounting holes for installing disc brake calipers on the rear foot end of the frame and front forks.

Changing the fork first depends on the specifications of your frame head tube, more than 700 mountain bikes may be a little overhang, because most of the vibration damping forks on the market are 1 3 8 inch untextured forks, and in my memory more than 700 mountain bikes seem to have not many such specifications, but it is not impossible to do so, if your original fork is a threaded upper tube, it is very difficult to buy, let alone hydraulic. Of course, if the specifications are suitable, you just need to buy a new fork and replace it, and nothing else needs to be replaced.

7th gear is not professional, unless you use ultra-old accessories, after all, it is now the world of 9-stage flywheels. First of all, look at how many stages your original speed shift, if it is a 6-stage turnbuckle flywheel, then you don't need to move anything else, just buy a 7-stage one and install it, and then match it with a 7-stage variable speed dial, the chain and rear derailleur can not be changed.

To be honest, there is no need to change the 700 yuan mountain bike, so let's buy a new car, and the price is about the same.

The purpose of the modification is, of course, to increase performance or sturdiness to adapt to different riding conditions.

But it's too general to be able to do it.

To put it simply: fork: the softness and hardness of the suspension effect, the length of the fork determines the angle of the car to determine the suitability for certain actions.

Crankset: Increasing the hardness of the crankset will reduce the unloading force and is not easy to deform, and the shape of the tooth also determines the smoothness of the shift.

Variable Speed: Faster variable speed to reduce time loss in race speeds. There is also an increase in feel.

Chain: same as crankset. It is also an important component that affects the speed and acceleration of the shift.

It is recommended that you go online or in professional car shops to communicate more with the old birds, which is not a simple problem.

Bicycle modification is particular about application, and you choose the wrong use with advanced parts is the same as garbage.

It's like a Ferrari that runs fast, but it certainly can't outrun a big-wheeled tractor in the mud.

Your car is 21 speed. Duke is 27 speed. You do have a little bit of a difference with him on this.

Talk about tires. You still have an advantage over him. You're a road tire.

He's a mountain tire. The resistance is big, and the weight of the car I think should be about the same. You're not as fast as him.

It is also necessary to consider many aspects. Physical strength should be the most critical. And then there's the performance of the car.

If you want to change it, it's shifting. But there's a lot more to it about. The first is that you have to change 24 or 27.

Your hubs need to be changed. Your gear lever needs to be changed. Your transmission needs to be changed.

The front crankset should be changed. The chain should also be replaced. Such a set will cost 1000k.

The fork doesn't have to be changed. But if you want to change it, you have to get a fork. It must be about 400k.

That's about it.

There is no need to change the frame, it is too cumbersome, and the flower bones have to be replaced.

Yes, you don't need to change it elsewhere, just remove it and put it back on.

No, it's not that much trouble to modify a bike, but it's a hassle if you want to convert it into a dedicated mountain bike, and I can't help it, I'm just a mountain bike enthusiast, not that professional.

Hehe, no matter how good the car is, no one pedaling is the same, the most important force. The forks of the 660 belong to the kind of normal suspension forks. So the fork generally does not need to be changed, the tires can be replaced with slightly narrower road tires, and the transmission does not need to be changed.

Think about it again, you can buy a new car with all the money you have modified, and you can buy a better car than the Duke 600, so you can overtake him by pedaling quickly. So it is recommended that you do not modify it, and if you want to ride a good bike, go and buy a new one.

Let's be honest. 660 is not very easy to change. The cost is larger.

Don't install disc brakes either. Loaded. To change the hub.

The hand changes to be changed. Yours is a handbrake conjoined one. To change the split.

The front plug should also be replaced. Troublesome. Just buy some personalized car stickers to dress up.

**Sold on. Within 100 yuan, you can get a makeover.

The key is still the issue of the engine. If you want to modify, the cheapest cost is at least about double that of your current car**. If you want to change it, then there is no bottom, and you would rather assemble one.

The tires of the 660 should be.

If you run the road a lot.

Then go to a bald tire.

And then the shock. If you have money, go and change it to Dart-2.

Much lighter than your original shock. Then there is the crankset in front.

You can go and change it to a better one. There are still a lot of things that aren't worth changing.

Mainly physical problems, I use 235 tires they 175 can not surpass me, if you go to school, change to a pair of 125 bald tires (you are afraid of too thin on the OK), and then sit to the most suitable position, the speed feeling will come up, this is the most trouble-free and cheapest way, like the upstairs can also be, depending on the personal economic situation.

You can change the tires with the pulling point, and the handlebars, seat bags, brake cables and transmission cables can all be changed to match the frame.

Change the handlebars and add the kilometer recorder.

Haha, it's better to change cars directly.

Mountain bikes are changed to road bikes, known as high-speed mountain bikes, or road mountain bikes, which are ridden on asphalt or asphalt flat roads, and the changed ones are significantly faster than those that have not been changed, and they are more combative, as long as the road surface is smooth, whether it is uphill or curved, the high-speed mountain bike performance or speed is faster than the original mountain bike, the reason is very simple, lighter and less resistant.

Common Hu Li's mountain bike to high-speed mountain bike, the front fork is replaced with an aluminum fork or a carbon fork hard fork, the original mountain steel fork, 3000 yuan mountain bike weight is generally above, high-end air fork different materials will be relatively lighter, and aluminum fork carbon fork, full of light, 10 percent of the car weight, acceleration and deceleration body is more light and sensitive, and the road sense is clearer.

The second need to change is the tire, the original mountain tire, up to 30km h can clearly hear the whirring sound of the interaction between the tire and the ground, first of all, the mountain tread is large, the tooth is deep, the weight is large, the resistance is large, the common is recommended to change to a light tire, lighter, less resistance, the modification knows that the unsprung weight is light 1g stronger than the body weight reduction of 10g.

Features of road bikes and high-speed mountain bikes

Cars of the same price, road cars and high-speed mountain bikes after the change are different in the strength of the frame, after all, the design is different from the beginning, you will find that when the violent acceleration is halfway, the road car frame collapse transmission force is obviously not as good as the mountain, as the saying goes, it is softer, and it will unload a little bit of force to do the circle of you.

The second road tire 700-23 is too thin, the slightly thicker speed bump is fast, the road bike bounce is more serious, the stability is slightly worse, the high-speed mountain bike, the third brake, the disc brake.

The performance is much stronger than the road car rubber brake, the brake at high speed is more confident, and the advantage is that the road car accelerates lightly and the top speed is faster.

If you want to compete with the speed of the road car, it is recommended that you change the road.

Because there are some differences in posture, angle and efficiency between road and mountain bikes, it doesn't mean that the shape is the same.

After all, road bikes are designed to be road racing, while mountain bikes are designed to be comfortable, efficient, and powerful.

There are two keys to the speed of the car:

First, the performance and weight of the car.

Second, people rot their own physical strength, strength, and explosiveness. Half of people and half of cars. In fact, mountain bikes with good performance are also quite fast at the end of the chain.

If you want to modify, first change the tires, 24* Magis can also be, and then replace the pedal with a large area of bearing, so that it is much less labor-saving to step on. In other aspects, it is not to install too much equipment and reduce the weight of the body, the effect is extraordinary.

Illegal! Article 58 of the Road Traffic Safety Law stipulates that the maximum speed of an electric bicycle shall not exceed 25 kilometers per hour when driving in a non-motorized lane. The relevant policies issued by various provinces and cities also clearly stipulate that modifications are not allowed, so it is illegal to modify electric bicycles and use modified electric bicycles.

The penalties for illegally modifying an e-bike vehicle are as follows:

1. If you change the color of the body, change the engine or frame of the vehicle, and fail to go through the change procedures within 10 days, you will be given a warning or a fine of less than 200 yuan;

2. Change the engine type, modify the vehicle exhaust pipe, increase the rear deflector wing of the vehicle, increase the searchlight before the vehicle accompanies the memory, order the restoration of the original state, and impose a warning or a fine of less than 500 yuan;

3. Replace the tire specifications of domestic vehicles, install large body surround protection devices, order them to restore their original state, and give a warning or a fine of less than 500 yuan.

Road Traffic Shelter Safety Act

Items (3) and (4) of Article 119 have clearly defined "motor vehicles" and "non-motor vehicles" respectively, that is, "motor vehicles" refer to wheeled vehicles that are driven or towed by power units and driven on roads for passenger use or for transporting rented and transported goods and carry out special engineering operations. "Non-motorized vehicles" refers to vehicles that are driven by human or animal power and driven on the road, as well as motorized wheelchairs for the disabled, electric bicycles and other vehicles that are driven by power units but are designed to meet the relevant national standards in terms of maximum speed, empty mass and dimensions.
