The principle of Mountain Bicycle

Introduction:

Mountain biking is a form of cross-country cycling, usually over rough terrain, using specially designed mountain bikes. Mountain bikes are similar to other bikes but include features designed to improve the durability and performance of rugged terrain. Mountain bikes are usually classified in a couple of categories: cross-country, cross-country riding, the whole mountain, downhill, free running, and soil jumps.

Detail:

Mountain bikes differ from other bikes in that they are designed for durability and rugged terrain. Most modern mountain bikes have some suspension, 26, 27.5-inch or 29-inch diameter tires, usually between 1.7 and 2.5 inches wide, and a wider, flat or upturned handlebar that makes the ride more upright and gives the rider more control. They have a smaller reinforced frame, usually made of wide tubes. Tires usually have a pronounced tread and are mounted on rims that are stronger than those used on most non-mountain bikes. Mountain bikes also tend to use hydraulic disc brakes more than other bikes. They also tend to use lower gear ratios to facilitate climbing steep hills and crossing obstacles. The pedal is different from the simple platform pedal. The rider only needs to put his/her shoes on the top of the pedal without the clip. The rider USES specially equipped shoes and the tacks are mechanically inserted into the pedal.

Accessories:

• Frame – the mountain bike frame is the foundation/skeleton/core of the bike. This is responsible for holding all the other mountain bike parts, whether they are the basic parts or bike accessories. It is very important that you decide the right frame size that matches your height and inseam to reward yourself a comfortable ride.
• Fork and Shock Absorber – The mountain bike suspension system minimizes vibration or vibration each time the bike is placed in an extreme position, such as on rough terrain or trails. The two general classification suspension systems are the front suspension and the double suspension. The front suspension has a set of shock absorbers attached to the front wheels. Double suspension with rear and front, very suitable for the technical field.
• Handlebar –the mountain bike handlebar is located at the front of the bike, this is what you used to steer or maneuver your bike. It also comes in different styles and shapes to meet the specific needs of any rider. This also holds the derailleur shifters, brake levers, headlight, and cyclocomputer attachment. As a general rule to provide additional comfort, the handlebar should be wider than the rider’s shoulders. The wider the handlebar, the more control, and leverage but the response time in making turns would be slower and difficult.
• Stem – mountain bike stems connect the steering tube of the fork and handlebars. This will help determine the distance of your reach to your handlebars and your position. The longer the stem, the more stretched out you are. Stems are measured in terms of millimeters.
• Saddle – mountain bike saddles help improve the comfort of your ride. Without a standard measure saddle that will catch your entire butt, then surely a pain on the road will be encountered. Take note also that more padding does not mean more comfort; it still depends on how you adjust your seat properly.
• Pedals – Mountain bike pedals are places where you put two feet to create a circular movement that moves the bike. Choosing the right pedals will make you a better rider, make your ride safer, give you better control over your bike, and provide more trampling efficiency. The four basic types of pedals are a basic platform, advanced platform, toe clamp or cage type and no clamp type.
• Tires – Mountain bike tires are the only bicycle parts that come in direct contact with the ground. Tires are generally wider and more elastic, providing better traction and stability. Most tires have internal inflation tubes/internals, but there are also newer changes, including tubeless tire systems. Important considerations when choosing a tire are weight, traction, and durability. Normally, mountain bikes have bigger tires than regular bikes.
• Chain – mountain bike chain is a circular set of links used to transfer the power from chainring to cassette.
• Front Derailleur – mountain bike front derailleur is used to shift the chainrings from one to the other. In short, the derailleur is used to change the speed of pedaling when biking.
• Rear Derailleur – mountain bike rear derailleur is used to shift the cassette from one to the other.
• Derailleur Shifters – mountain bike shifters control the front and rear derailleur, allowing the shifting of the gear from low to high speed and vice versa especially when crossing different terrains. The shifters almost have a similar look with the brake levers and are located next to the handle grips.
• Brakes – mountain bike brakes are a very important part of the bike because of its primary purpose to stop the bike. Aside from that, they also help regulate the speed, control your bike and make it possible to perform advanced techniques. The two basic types of brakes are the disc brakes and the rim brakes. Disc brakes perform best even on muddy situations, but they are usually heavier than rim brakes.

Conclusion:

Mountain biking is a type of bicycle used in cross-country sports or another rugged terrain.Unlike other bikes, many of its accessories focus more on durability and control than regular bikes. For example, larger tires and suspension, larger rims, and the use of hydraulic disc brakes are all for better hill climbing and obstacle crossing.

Reflection #2

In this project, I enjoyed working on it because it can choose whatever you like, and then to doing the research. This object I picked on this project is mountain bicycle, I explained all the things it need and how does each things work. I think I did well on this project, because I also explained why it is difference with other bicycle. Ride a bicycle in mountain is much harder than road, so the principle of mountain Bicycle is focus on this part. For this project, I will give myself a 90, because what I did on it is the comparison with other bike, and the explain how each part works.
