Are Chinese bikes good?

Chinese Bikes have a massive market both inside China and globally. There’s a plethora of carbon Bikes manufacturers in China that cater to this vast and ever-expanding market.

The purchasing power of people across the globe that prefer Bikes differs. It also depends upon the reason of their preference.

In many countries, such as the Netherlands, Germany, Norway, and Sweden, environmental consciousness is high. In growing economies such as India, Brazil, or China itself, many people choose Bikes simply because oil is too much expensive.

Bike could transform China’s cities, cut pollution, improve the health of millions of people, and provide a model for commuters and sharing companies everywhere. bike trends from China that could outlast the pandemic, and shape how we travel for years to come.

Are all carbon bike frames made in China?

Not all carbon fiber frames are made in China.

In the public’s understanding, many things are made in China, so it is correct to say that. Most of the carbon fiber products in the bicycle industry come from Taiwan or mainland China. But some carbon fiber frames and parts are also made in the United States and France.

Although carbon fiber is well known as a space material in the early days, carbon fiber is actually very suitable for small-scale processing. Small American stores and even private workshops can process carbon. Many bicycle manufacturers can make their own bicycle frames from carbon fiber cloth, and the manufacturing method is no different from that of large bicycle manufacturers.

But the raw carbon does come from China. Carbon fiber is made of polyacrylonitrile (PAN) fiber. The polyacrylonitrile fiber will be heated to a very high temperature, and the non-carbon materials in the fiber will be burned out, leaving only a series of very thin long fibers. The more fully processed, the greater the rigidity of the material

This is a complex industrial process, and only a few companies in the world have the ability to manufacture raw carbon fiber materials. Through the 2010 US Department of Energy report, we can find that more than 90% of the global carbon fiber supply comes from only six companies: Toray, Teijin Group, Mitsubishi Rayon, Zoltek, Hexcel and Cytec. Toray, Teijin and Mitsubishi contracted almost two-thirds of the world’s carbon fiber production. Zoltek, Hexcel and Cytec are headquartered in the United States and produce less than one-third of the global carbon fiber output.

Are mountain bikes Carbon?

Not all the mountain bikes are carbon, General are steel / aluminum/titanium/ carbon.

but more and more people will prefer to buy carbon frame mountain bike. It is lighter, absorbs impact better, and can easily be made into any shape of frame.

For steel frame,it is easy to weld, low price, better absorption of impact force, beautiful appearance, and usually more classic shape. But the biggest disadvantage of steel is that it is easy to be corroded, so rust prevention is a big problem, and the steel frame is relatively heavier.

For aluminum, the weight is relatively light, not easy to change, the processing is relatively easy, and the price is relatively cheap. The disadvantages heat treatment is required to increase the strength, and the fatigue performance is relatively poor.

For Titanium, advantages is the frame is relatively light, strong, and has a better riding feeling and high corrosion resistance. Disadvantages is the price is more expensive.

Everyone likes different materials. According to the advantages and disadvantages of different materials above, it is very important to buy a bicycle that you like.

how durable are carbon fiber mountain bike frames?

Many riders are afraid of damaging an expensive carbon frame. Carbon fiber’s strength to weight ratio is higher than steel and carbon frames can survive a lot of abuse. It also has a nearly infinite fatigue life and, under perfect conditions, long-term use won’t “wear it out.” The resin, however, can degrade when exposed to UV light, but that’s why frames are painted, even “raw” frames have clear coats with UV inhibitors built in. Carbon is so much more compliant, comfortable yet refined. There’s just something to leaning into a very fast curve and applying power on a carbon bike that you just don’t get with aluminum. If you just want a long ride anywhere, Carbon is so much more comfortable, posh, fast, responsive and controllable. It’s like having a BMW. Smooth, nice… fast!

Carbon mountain bike is very durable in general. The power-to-weight ratio is 18 percent higher than aluminum. High-end mountain bike frames can take up to 700 KSI (kilopound per square inch) before they snap.When a carbon mountain bike crashes, it neither bends nor dents, instead, it cracks. This damage can be invisible or visible. And this is probably why it has earned a bad rap in the durability department. Once the integrity of the composite is compromised, it becomes very fragile and therefore dangerous to continue using. As such, it should either be repaired or replaced.Just like other materials, carbon will deteriorate with usage albeit, only after a long time. Carbon has the longest frame fatigue which enables many manufacturers to offer a lifetime warranty on frames made with this material. When aging happens, the resin matrix would be forming little cracks, and all that’s left are the connections of the fiber. The stiffness of the bike frame will slightly change in the process.

how to cut carbon fiber mountain bike ?

For a carbon bar, use a hacksaw with a tungsten carbide blade. Place masking tape over the cut mark and make a mark on top of the masking tape. This will prevent the carbon from fraying. Place the handlebars in a bike stand and clamp down so they are parallel with the floor.

When choosing a new handlebar width, be conservative. It is always possible to remove more later. Also be sure to reduce width evenly — when shortening bars by 40mm total, cut 20mm from each side.

There are several methods that can be used to determine bar width — here are a few of our favorites: Sit on the bike. Close your eyes (make sure the bike is stable), reach out and grab the handlebars at a position that feels right. Take a measurement of the excess length of the grip starting at the outer edge of your hand. Subtract at least 10 mm from this number to allow yourself some extra margin — again, be conservative. This number is the amount you will remove from each end of the handlebar.

This technique will require a helping hand. Prepare to do a push-up, with your hands on the ground shoulder-width apart. Have someone measure the positioning of your hands, from the outside of one hand to the other. Again, add 20 mm for a comfortable margin, and you have the ideal total width of your handlebars.
