In our time, there is a great variety of different vehicles. And every year there are more and more of them. How did it all begin? One of the most common answers to this question is the bicycle. Although this is not entirely correct, today we will talk about it. By definition, it is a vehicle on wheels that is propelled by the force of a person’s muscles through the pedals.
A long time ago, a person thought about how to facilitate the overcoming of long distances and with the help of what it can be done. So, the prototype of our modern bicycle was born. And it happened in 1817. German scientist Karl Drez invented the first scooter in history. It was very similar to our bike, though without pedals and with a wooden frame. And in 1884, the Englishman John Starley created the bicycle itself in the form that we are used to seeing today, and called it “The Drifter”. This is how the history of the world’s most widespread environmentally friendly mode of transport began.
Currently, there are more than 30 varieties of “bikes”, as the common people often call them. They are all designed for a wide variety of needs, but the principle of operation is the same.
Bicycles are usually divided into several groups:
- by the type of movement: road. for long trips, road. for moving in urban areas, extreme. for sports competitions, mountain hardtails are perfect for road surfaces with different levels of difficulty, cross-country. for traveling over rough terrain, etc. ;
- by the level of professionalism: for amateurs and beginners, experienced cyclists and professionals;
- by design features: compact (folding), 2-hanging, 3-hanging, with a female frame.
- by manufacturer brands (Stels, Merida, Stark, Giant, Trek, etc.);
- by age: children’s bicycles, as well as adults and teenagers (bicycles for girls and boys, taking into account age characteristics);
- by material of manufacture: carbon, steel, aluminum, etc.
Maximum load on bike
Many manufacturers do not specify the maximum load on their bikes in any way. The implication is that the average adult bike will withstand a margin. Those manufacturers who indicate the maximum weight of a cyclist usually give figures in the range of 105-115 kg. So, if your weight fits into 100 kg, then any quality bike will suit you.
Naturally, you need to understand that you shouldn’t ride a road bike on curbs. That is, the bike must be used in accordance with its intended purpose. If your weight exceeds 100 kg, then you should choose a bike taking into account additional conditions.
What are the most durable bike types? Usually these are either mountain bikes, designed for relatively tough operation on rough terrain, or durable city bikes, which were not so economical on bike weight. It’s better to look for a bicycle for a man of 120 kg yourself.
There are not just bicycles, but super-bicycles, champions in their niche. Let’s tell a little more about them.
Big champion bikes
Longest bike in the world: According to the Guinness Book of Records, it is longer than the longest limousine car, which is “only” 30.4 meters long. The bike is the creation of a group of cyclist enthusiasts called Mijl Van Mares Werkploeg from the Netherlands. To create it, they used elements of aluminum structures intended for the installation of lighting devices on concert stages. The strength of these structures is sufficient to support their own weight and withstand the loads occurring at such a length with practically no sagging.
The tallest bicycle in the world was created in 2012 by a welder from Cuba, Felix Guirola. His brainchild reaches 5.4 meters in height. He designed and built it himself. In appearance, this design is not much like a bicycle. However, the presence of a seat and pedals with which it moves, as well as a pair of wheels, still confirms this. To get to the seat, there is a special ladder with which the device is equipped. By the way, three assistants who helped Felix climb up, and accelerated the bike at the beginning of the journey, accompanied him all the way, so that in case of a fall, he could pick up the poor man. Passers-by perceived such a spectacle with humor.
By the way, we recommend:
The largest wheel size on the planet is the great “Frankensike”, invented in 1989 by the American Dave Moore, who hails from California. The height from seat to ground is 3.4 meters and the wheel size is 3.05 meters. Daredevil Steve Gordon made a trip on it without insurance on June 4 of the same year.
The longest two-wheeled bicycle was created by Terry Tessman, a resident of New Zealand. The length of this vehicle is over 22 meters with a mass of 340 kg. Four people managed to ride it at the same time in the winter of 1988.
Interesting! The bicycle of Australian Neville Patten is considered to be the smallest, the wheel size of which is slightly less than 2 cm. The most amazing thing is that the designer was able to ride it as much as 4 meters. This is a record!

Bicycle rear hub: device and assembly instructions
The rear hub of a bicycle must always be in good condition, because it is it that determines the smooth running of a two-wheeled vehicle. According to many cyclists, the ride quality of a bike depends largely on the type and mechanical performance of the frame. However, in practice, the defining moment here is the state of the undercarriage. bushings, carriages, chains, and other systems.
According to compatibility with different types of brake systems, there are several distinct types of rear hubs:
- for disc brakes;
- for roller brakes;
- for rim brakes.
Of course, the more complex rear hub of a bicycle, designed to be connected to a disc brake system, can easily be used to assemble a wheel with rim brakes, but not vice versa.
The rear hub of a bicycle includes the following structural elements:
This component of the rear hub design acts as a connecting shell for other functional mechanisms. The main requirement for the body is a high degree of rigidity, since during the ride the hub is subjected to significant torsional loads.
The rear wheel hub of the bicycle can be protected by a stamped or cast body. The most reliable high-strength housings are produced in the first way.
They are specific annular protrusions that are contained on the rear hub body. This element is used to connect with the spokes of the wheel. Flanges contain special holes where spokes are inserted when dialing.
The main requirement for flanges is a high strength index. Based on the insignificant size of the part, it is enough just to imagine how much increased loads fall on its share. After all, a third of the structure of the bicycle, together with the cyclist, is located precisely above the area where the rear flanges are located.
The rear hub of the bicycle must be equipped with bearings with a dust cover. Only in this case it will be possible to forget about their maintenance and replacement, having driven more than 10,000 km on the bike. Frankly low-quality bearings will make you endure unpleasant sounds and suffer from wheel backlash after the first ride in rainy weather, not to mention winter. Reliable dirt protection is represented by various seals that prevent contact of the lubricant with the external environment.
Currently, there are bulk and industrial bearings for rear bushings. The difference is that the wheel play can be eliminated by performing the usual adjustment of the bulk bearings. If there is a similar problem in the case of industrial bearings, most likely they will have to be replaced. Therefore, the rear wheel hub of a bicycle should be selected based on the type and reliability of the bearings.
The main parameter of the rear hub axle is its length. To select the hub according to the axle length, you just need to measure the distance between the opposite outer nuts on the corresponding mountings of the bicycle frame.
Having studied the internal and external design of the rear bicycle hub, it is recommended to pay attention to the wide range of standard sizes of this system. The presence of some differences in parameters is due to the use of hubs on various types of bicycles:
- track models. 10×120 mm;
- road bikes. 10×130 mm;
- the bulk of the common mountain models. 10×135 mm;
- downhill bicycles. 12×135 mm;
- professional class models “cross country”. 12×142 mm;
- models of bicycles for freestyle, extreme sports. 12×150 mm;
- BMX bikes. 14×110 mm.
The rear hub device of a mountain bike has some differences from the design of the chassis for road bikes.
Bushings for road and road bike models have oil seals. special seals designed to protect the bearings from contamination. Often glands are integrated into a single piece with tapered elements.
Bicycle rear hub “Stealth”, as well as other common models of mountain and off-road bikes, in addition to the oil seals connected to the cones, it often has rubber anthers. The presence of such elements helps to increase the protection of the chassis from dirt, all kinds of debris and dust.
Unlike the road bike category, mountain bikes are designed to ride in the most rugged terrain. Naturally, the use of additional protection for the rear hub mechanism proportionally increases the weight of the two-wheeled vehicle and reduces the ease of movement. That is why the assembly of the rear hub of a road bike is carried out by most manufacturers without installing these elements.
We should also consider the design features of bicycles with disc brakes. Here mechanisms are used, the flanges of which are connected to the brake discs.
Differences are also present in the methods of connecting the ratchets to the hub with the cassette mounts. Most common domestic bike models contain hubs with built-in ratchets. In contrast, the rear hub of a speed bike is usually a screw-on type of ratchet.
In the overwhelming majority, the rear bushings are asymmetric, since a cassette or a rear sprocket must be located on the right side of the mechanism. Compared to the left, the right flange is closer to the center of the axis. As a result, on the right side of the spoke is slightly shorter.
There is a special type of planetary bushings. The internal structure of such products contains a mechanism for shifting gears. Only one star is installed on such systems. The bushings of this plan can be operated without installing a chain tensioner.
How to assemble a rear bike hub?
When assembling the mechanism, you need to take into account the fact that the left and right ends of the axis have some differences. The right cone is firmly connected to the axle, additionally secured with a lock nut and therefore never dismantled. The system is adjusted by changing the position of the left cone.
When trying to figure out how to assemble the rear hub of a bike, the main thing is. do not confuse the side on which the axle with the right taper is to be installed. It is much easier to make a mistake here than in the case of a front wheel assembly, where both sides of the mechanism look identical.
The following sequence of actions will allow you to avoid trouble by connecting the elements of the rear hub into a single whole during installation:
- To begin with, the bushing body, ratchets and the surface of the cups for mounting the system are cleaned of dirt, remnants of old grease, after which a new grease base with a thick consistency is applied.
- Using tweezers, the balls of the bearings are placed in the right place and pressed into a layer of grease, the amount of which should be sufficient to prevent the balls from rolling back.
- On the ratchet side, an axle with a right taper is installed. The operation is carried out carefully, as there is a high risk of pushing the bearing balls out of the bowl.
- Finally, the left cone is screwed onto the axle almost to the stop, but not tightened. Washers are screwed on in the correct sequence, after which the locknuts are attached.
At this point, the rear hub is considered practically assembled. The only thing left is the installation of rubber boots. However, it is advisable to do this only after the final adjustment of the chassis.
Bicycle rear hub. repair
As practice shows, the most common and typical malfunction of the rear hub is excessive tightening or loosening of the cone. In the latter case, a noticeable rear wheel play will have to be tolerated. Conversely, overtightening the taper mechanism will result in a tighter, more difficult ride for the two-wheeled vehicle. In addition, a crunching sound may occur in bearings.
What to do when a loose rear hub is the cause of play? The repair in this case will consist in tightening the cones with special wrenches. Open-end wrenches of 15 and 20 mm are suitable for this, with the help of which the locknuts are first unscrewed, and then the cones are clamped or loosened to the desired limit.
Ideally, there should be no backlash on the bike. If the adjustment of the tapered mechanisms of the rear hub was made correctly, the wheel will rotate easily without additional impulse, only under the influence of gravity on the reflectors.
Bending of the bushing often becomes the cause of breakage. This most often happens when using low-quality, inexpensive parts. If this happens, only a complete replacement of the axle with a new, more reliable one will solve the problem.
To make repairs or routine maintenance of the rear wheel hub easier, it is recommended that the ratchets be removed in advance. However, when the whole essence of the repair is the usual tightening or loosening of the cones, it is not at all necessary to resort to such an action.
Ultimately, in order to avoid unnecessary problems in the form of a long downtime of the bike and waste on expensive repairs, it is enough to regularly undergo maintenance. Most often, the essence of maintenance is reduced to the bulkhead of mechanisms, their cleaning, lubrication and installation in the reverse order.
Which is the best bike. mountain or road?
Choosing a bike is not easy. Especially in today’s marketplace, where advertisers eager to grab customer money are ready to present many stands and evidence that this bike is right for you. Nevertheless, if you turn on your brain and approach the question in detail, then choosing the right bike will not be difficult.
So, the first thing to do is to answer the questions: “In what road conditions will the bike be used? For what purposes is it purchased? ” If the bike will be used in off-road and rough terrain, then the choice should fall on a mountain bike.
In contrast to the mountain bike, there is a road bike, incomparable and irreplaceable when traveling around the city and asphalt. In order to simplify the selection task, below is a detailed analysis of the most popular mountain and road bike models.
Before starting to consider the differences, it is necessary to understand what subspecies mountain and road bikes are divided into.
Types of mountain bikes
Cross-country (Cross-country). This bike was designed for off-road riding. It is usually supplied with a front shock absorber. The lightness and strength of the design makes it convenient for travel both in the city and in rough terrain.
ATV (All-road bike). It is the most common type of mountain bike. Technical characteristics allow it to be used in a moderately sparing mode. Ideal for measured journeys in both urban and rough terrain.
DownHill. Designed for descents from the mountains and movement in rough terrain.
This bike is not intended for a calm and measured ride in urban conditions. The main function is to provide the most comfortable handling in conditions of descent and to preserve the frame structure during falls.
Types of road bikes
Road bike. Designed for driving on a flat road at high speed.
City bike. Indispensable for measured and comfortable trips around the city and flat roads.
Touring. It is the most versatile road bike. Able to provide a comfortable ride both in urban conditions and in light off-road conditions.
Differences between mountain bikes and road bikes
Road bikes are designed and built to travel at medium to high speeds on level ground, usually asphalt.
The frame design and low handlebar position provide the cyclist with a hunched-over riding position. This ensures that the maximum possible energy is transferred from the cyclist’s feet to the pedals.
Mountain bikes are designed for cross-country travel in off-road conditions. The frames are made as strong as possible to withstand aggressive use. Typically equipped with vibration dampers and a wide handlebar for maximum control while driving.
Lightweight design for road bikes is a must to maintain speed and maximize ride comfort.
Since mountain bikes are not designed for high-speed rides, a heavy bike weight is a must in order to provide the necessary margin of safety and resistance to deformation during falls.
Wide tires with deep tread on mountain bikes increase the contact area of the rubber with the surface, which increases friction and, as a result, stability and cross-country ability.
On the other hand, road bikes are narrow and smooth. One would think why not apply wide-tread technology to a road bike. But there is no particular need for this, because when rubber interacts with asphalt, a sufficiently high coefficient of friction is formed, which ensures a comfortable and confident ride.
Generally, road bikes are designed to cover distances on smooth surfaces at high speeds and do not have a moveable suspension. This is not necessary because the bike is not designed to travel on uneven surfaces.
In contrast to the road bike, there is a mountain bike. For him, the presence of a shock absorber, at least a front one, is absolutely necessary.
Thus, by answering the above questions and understanding the technical characteristics, choosing a bike will not be difficult.
Key features of choosing a road bike
Home »Choosing a Bike» Key Features of Choosing a Road Bike
The very first bicycles that man created were road bicycles. Later, sports, beach, mountain and others were designed. However, it is the road bike that remains the most popular to this day. There are several reasons for this: low cost, structural reliability and safety. It is this combination that makes road bikes so popular.
What is a road bike?
Other features of a road bike include a curved handlebar, a high frame, a rigid carbon fork, narrow wheels with smooth tires, 2-3 leading stars with a small pitch, integrated brake levers.
Also, city bikes are mistakenly classified as road bicycles. Modern city road bikes are designed for a leisurely ride. They have a closed or open frame, large wheels, a wide steering wheel, protective guards on the chain, headlights, and rear-view mirrors. Sometimes these models are equipped with a manual gearshift.
Now let’s move on to the topic of our conversation. classic road bikes. Their design includes:
- Steel frame. In rare cases. aluminum. Women’s road bikes can be foldable.
- Steel hoops for wheels.
- Wide enough handlebars.
- Wide seat.
- Mud flaps.
- Chain cover.
- Foot drum brakes (unlike road models equipped with hand brakes).
Road bike selection rules
To choose an adult road bike, you need to know a few important nuances. Consider the key points of choosing a city bike.
First of all, you need to pay attention to the number of welding seams, the material and shape of the frame:
- The quality frame is made from high carbon steel. Bicycles with a frame made of this material can last up to 10 years or more. Frames made of aluminum or mild steel are soft and bend quickly.
- The number of welds on good bicycles does not exceed 3-4. If there are more seams, then the frame was made of low-grade material.
- Frame shape. curved or flat. Smooth curves have better shock absorption. A frame with right angles and no bends is stiffer, but stronger. By the way, often flat frames are noticeably thinner than curved ones.
- Frame type: open or closed. Typically, men’s road bike has a closed high frame, women’s. open and low.
When choosing them, attention should be paid to the diameter of the hoop and the width of the rubber.
- The larger the diameter, and it can be from 20 “to 28”, the faster and more stable the road bike will go.
- Wheels with a smaller hoop diameter are more suitable for teenagers or beginner cyclists. They are maneuverable, and in extreme situations it is easier for the driver to cope with control.
- The tread width is selected on the same basis as the wheel diameter. The wider the wheel, the more stable the bike behaves, the narrower. the more careful the driver should be on the road.
A beginner should pay attention to this indicator. Any road bike. male, female or child. must be suitable for the driver’s height. You can determine this indicator using the table (taken from the original Giant bicycle catalog 2011. 2012)
Frame tube length
How a mountain bike differs from city and other types?
Mountain biking is the dream of most young and adult fans of extreme riding. This category of two-wheeled vehicles is rightfully considered off-road. it does not depend on the quality of the surface and is able to overcome even narrow paths and gorges. Of course, not every mountain bike owner has to ride the canyons, but the very opportunity not to think about obstacles can inspire even the most inexperienced extreme lovers to feats.
What are the differences from road bicycles for this popular transport? Is it worth comparing it with sports models? Is there a big difference with road and regular bikes? In fact, mountain bike does not belong to highly specialized categories of transport, but it cannot be called a universal solution either. Such a bike copes better than others with riding on rough terrain, suitable for mastering some sports disciplines. But in order to understand how it differs from others, it is worth comparing different types of two-wheeled vehicles with each other.
General characteristics of a mountain bike
Mountain bike, or simply MTB, is a well-known mountain bike designed specifically for off-road travel. These models traditionally have:
- wider tires, thicker, with clearly and deeply expressed toes;
- chain transmission with speed switch;
- the steering block brought forward;
- trapezoidal frame;
- shock absorber for vibration dampening;
- rear suspension (optional);
- raised carriage.
A standard mountain bike for sports use is equipped with attachments and can be both light. from 6 kg, and quite heavy, the maximum curb weight reaches 19 kg. Common wheel diameters for this class are 24, 26, 27.5 and 29 inches. Since 1990, mountain bikes have gained international recognition and are used in sports. The modern classification of these vehicles includes such models.
- Freeride. Free riding on a track with obstacles requires the use of full-suspension bicycles with powerful brakes.
- Bicycle trial. Discipline involves the cyclist overcoming obstacles. The main task is not to lean any part of the body on the ground or other objects. All natural and artificial obstacles are passed by the rider in the bike saddle.
- Downhill. Downhill timed down the track with sharp turns, unexpected traps in the form of cliffs and jumps, natural obstacles are carried out on the heaviest bicycles in the mountain class. The standard wheel diameter in this discipline is 27.5.
- Cross country. The discipline where the lightest mountain bikes are used. There is a classic format of a race in a circle with a changing type of terrain, a marathon and an eliminator. a survival race.
- All mountain. Some of the lightest bikes are used here, and the rides are like freeriding.
The main differences
How is a mountain bike different from other types? In most cases, it will not be difficult to feel the difference. it is in the position of the rider’s body, the intensity of the load on his shoulders and arms.
Comparing models of different types will help to assess these differences more fully and accurately.
A classic road bike. the most common, walking or touring bike noticeably loses to a mountain bike both in the choice of speed mode and in cross-country ability. But in such models, the gender difference is clearly visible. women do not have a transverse tube that increases rigidity, they are often made in a folding version. City bikes are equipped with a vertical saddle that is tall, wide and has a spring block for support. The steering wheel in such models has an inclination towards the rider’s body, it is located high and does not require changing the position of the rider while driving.
In fact, road bicycles are created exclusively for leisurely riding at your own pleasure. you will not be able to develop significant speed with their help, and the absence of shock absorbers (they are rarely used) will significantly complicate any exit outside the asphalt path.
The complete set of city bikes is also quite noticeably different from mountain bikes. They initially include fenders, full-size, anti-splashing mud, trunk, reflectors and headlights. Riding in mud on a mountain bike without wings will definitely not be fun, but it will allow you to overcome obstacles. The urban model will get bogged down on the approach to the obstacle.
From the highway
This type of bicycle can be classified as a sports bike. there are races in the discipline, and in general it is quite popular. High-speed road models, but demonstrate their best qualities exclusively on flat surfaces. In off-road conditions, they are almost impossible to use due to the lack of the necessary equipment.
Another obvious difference is the shape of the steering wheel, which at first glance demonstrates the sporty character. It is steeply curved and allows the athlete to keep the body almost horizontal during movement, leaning strongly forward. The saddle is also different. here it is longer and narrower, it allows you not to rub the inner thighs even with prolonged contact. The handlebars of the mountain bike are wide and almost straight, located above the seat and provide optimal balance in both the seated position and when moving while standing on the pedals.
The road fork is always rigid. Mountain bikes are equipped with shock absorbers, but there are also options similar to sports. Rigid fork does not fit all models.
Comparing sports and mountain bikes is not very appropriate. simply because their goals are too different. In the Sport class models, the emphasis is on speed performance and ergonomics to reduce energy loss while driving. They do not use shock-absorbing suspensions. they “dampen” part of the effort transmitted by the athlete during pedaling. Accordingly, any irregularities on the road strongly affect the rider’s well-being and the condition of the equipment itself.
The class of the sports bike also matters. For example, the design of racing models is simplified as much as possible. the rear wheel has a solid disc design, a short frame maximally lightens the weight of the equipment itself. The saddle in these sports bikes is located above the handlebars, which helps to maintain optimal aerodynamics while traveling. Brakes are often absent or represented by the simplest “tick” in the front, the gearshift system is also missing.
The hybrid bike combines the properties of road and mountain types and allows you to find a compromise between comfortable movement on a flat road and overcoming off-road. Visually, it is closer to mountain bikes, the material is carbon, steel or aluminum, but the travel of such models is softer and lighter. The wheels on the hybrids are large. 28 ″, the tires are thinner and narrower, the tread pattern is smoothed, closer to the road.
The hybrids are equipped with a fork damper and use a mountain bike handlebar. It seems that in such a combination all possible disadvantages have been eliminated. But in practice there are problems, and they are quite obvious. This technique implies a higher seating position, which in combination with a mountain handlebar creates some discomfort and increases the load on the arms.
Which bike to choose for regular commuting? If you plan to select a model for the city, but with the possibility of going outside the highway, you should not deny yourself the pleasure of purchasing a full-fledged mountain bike. It is also suitable for active teenagers or young people who want to learn simple tricks or go on a trip. In addition, the quality of the road surface is not so important for a mountain bike, thanks to the shock absorbers, it more easily tolerates hard contact with the road.
Another reason to choose a mountain bike is the extra wide wheels to improve the stability of the vehicle. It is good for beginner riders and makes them safer during the learning phase. The choice in the mountain bike class is the largest. you can choose a hardtail from the budget segment or purchase a truly passable two-suspension version for professional sports. In addition, they implement mechanisms to reduce vibration, reduce the load on the hands and spine.
If you plan to drive exclusively on a perfectly flat highway or participate in classic cycling races, you can choose the regular road option. It is good for building physical shape or long-distance cycling trips across Europe. For leisurely skiing in the park near the house, you can do with the city option. the walking model is suitable for those who, in general, do not seek to conquer sports peaks and ride for pleasure.
Considering the quality and condition of the roads, we can safely recommend a mountain bike with gear shifting for choosing. It is suitable for long periods in the saddle, as opposed to a sporty one. Better road holding compared to hybrid. especially on shaky, loose soils and has the most robust construction.

How a mountain bike differs from a city bike?
Not motorcycles, not motor vehicles will never destroy the popularity of bicycles among people. This type of transport is developing more and more and now it is no longer the simplest of mechanisms for movement over short distances, but something that is improving every day.
Those who used to be suspicious of a bicycle as a transport, after the purchase, strive to make up for lost time: routes are looked for, equipment is chosen, even the desire to find companions in hobby is understandable. The most difficult question remains which type of bike to choose for yourself.
Features of bicycles
If earlier there were only two categories of bicycles: sports and road (if we do not take into account children’s and teenage types), now the list has increased:
- sports road.
All of these categories are made taking into account individual abilities, therefore they are divided into men, women, children and teenagers. The design takes into account weight, physical activity and other technical characteristics. Now you can dwell in more detail on the two most popular categories of bicycles. mountain and city.
The mountain bike was specially designed for those off-road sections that are not always easy to overcome on foot. Where a road bike could not be used as a transport, and it hindered rather than helped in movement, mechanics modified by engineering thought made it possible to overcome the most serious obstacles.
An important factor is the physical endurance and training of the cyclist, but practice is a profitable business, if the decision is made to purchase an off-road miracle on two wheels, the mountain type of bike is the very thing that is required.
Mountain bike features
Extreme operating conditions require increased strength from the mechanics and other elements of the mountain bike, and this is all taken into account when choosing the right type of bike. What is the peculiarity of the technical characteristics of mountain bikes:
- The frame and fork are equipped with shock absorbers, the stiffness of which is stipulated by the bike category.
- Reinforced frame option.
- Use on some types of rear suspension.
- Reinforced rims and other wheel elements, including tires.
- The carriage is almost flush with the bushings.
- Whiter than high strength of elements that provide not only a change in the speed of movement, but also the force of a mechanical transmission. Particular attention is paid to the mechanics, ensuring safe (shock absorbers, springs) ascent and descent in areas with more than a critical angle of inclination.
- The presence of several reduced speeds. This condition allows you to overcome ascents of significant steepness elevations and for movement on especially difficult routes.
- The location of the steering wheel, in relation to the rack with a slightly forward extension, for convenience when moving with a shoulder load.
Modern mountain bike
Modern modifications are replacing the mechanics and fixtures that were previously used for braking with newer technologies. Instead of rim pads, where, as a transfer of force from the muscles of the hand to the cable, they were forced to brake by pressing the segments, they replaced them with newer equipment. disc brakes, where brake fluid pumped into the system is used. To reduce the total weight in the construction of the frame, a particularly durable, but not heavy material is used: titanium, polymers, aluminum alloys, carbon.
Features of city bikes
- Wider but more efficient steering wheel for enhanced maneuvering ability.
- Installation of special shields to ensure traffic safety and protection from dust and dirt on clothing. There are differences in categories for women and men.
- Larger wheel diameter with medium-width tires and treads for traction and faster speeds. For movement on asphalt, treads with a fine pattern are used.
- Braking control is often limited to only the rear foot brakes.
- The presence of small trunks and special chairs for transporting children.
- Damping due to the design of the springs that are in the seat.
- Using multi-speed bushings to change speeds.
- Taller frame.
- Chain protection.
- Availability of rear-view mirrors, signal reflectors and devices for giving sound signals.
Women’s city bike
The main differences
Now that the technical specifications of both categories of bikes are provided, it is possible to understand what the difference is, and how it can be used when choosing a purchase.
- Mountain bikes are heavier in weight, if city bikes are easy to carry in the hands in case of obstacles, then in the case of SUVs this is not the best way out.
- The cross-country passability of mountain sports bikes is an order of magnitude higher than that of urban counterparts, but on good road surfaces they are inferior in speed and maneuverability.
- Both categories are easily modified with commercially available accessories ranging from mechanical devices to frames, pedals, brakes.
- Wider tires work well off-road, but on asphalt they create a noticeable vibration and increased resistance, so city bikes are preferable in this case.
- City bicycles provide for collapsible frames on some models, which is very convenient for storing them in city apartments, this can hardly be called a significant plus, since over time the connections acquire unnecessary development and play, which affects the ride. These bikes are good for short and easy distances.
If mountain bikes are more reliable in operation: they are durable, it is more difficult to “kill” them by mechanical loads and if they can be used for a rather long period without serious breakdowns, then their price is much higher. When choosing the right bike, it is important to take into account the estimated distances and loads, how this may affect the operation, and only then decide on the purchase.
How a mountain bike differs from a road bike
Choosing a bike is not an easy task, especially in the realities of today’s market and high competition. Depending on the conditions in which the bike will be used and for what purposes it is purchased, the appropriate type is determined. So, a mountain bike is suitable for rough terrain and off-road, and a road bike is suitable for driving on city flat asphalt. But what is the difference between a city bike and a mountain bike? In this article, we provide a detailed analysis of each of the types.
What are mountain bikes
ATB (All Terrain). The design of the bike allows you to use it both for measured trips in city conditions and for rough terrain.
Cross-country. Lightweight and durable, the bike is ideal for off-roading, and the front shock absorber “smoothes” bumps and other uneven surfaces.
Downhill. Designed for descending from the mountains, providing the most comfortable handling, as well as for driving on rough terrain.
Types of road bikes
Highway. Designed for those who love speed, suitable for riding on smooth asphalt.
Urban. Will appeal to lovers of leisurely cycling along the city routes.
Touring. A versatile bike capable of providing comfortable riding conditions both in the city and off-road.
Mountain or city bike: what’s the difference?
Mountain bikes are made for off-road driving. It is the specific nature of the operation that determines the fact that the frames of such bikes are made of high-strength materials, because it is quite difficult to withstand the test with bumps and pits. Most models are equipped with a wide handlebar to maintain control of the bike while driving, as well as a front shock absorber to reduce vibration.
Road bikes have design features that make them ideal for riding on smooth paved paths at high speeds. Due to the low position of the handlebars and the specific design of the frame, the cyclist takes a “hunched over” position when riding, but it is this position that provides fast speed.
Another difference between a mountain bike and a city bike is the weight of each of the designs. So, the lightness of the components of the “road builder” is due to the need for a quick set of speed.
Mountain bikes, due to their inability to ride fast, have a significant weight, which allows you to ensure the integrity of the structure during aggressive skiing from the mountains or off-road, as well as prevent frame deformation during falls.
Due to the fact that road bikes are designed for riding on a flat road and are not intended for riding on potholes and bumps, it makes no sense to introduce a movable suspension into their design.
The design of mountain bikes is characterized by the presence of shock absorbers (or one shock absorber. front), the implementation of which is due to the purpose of the bike.
“Gorniki”, as a rule, are equipped with wide tires with a deep pattern, which are designed to increase the area of contact of the wheel with the ground and the friction force, thereby increasing the cross-country ability and stability of the bike.
Road bikes, on the other hand, are equipped with a narrow tire with a shallow tread, because the interaction of rubber and smooth asphalt produces a sufficient coefficient of friction to ensure a confident and comfortable ride.
Having decided on the conditions in which your future bike will be used and knowing how a mountain bike differs from a regular (road) bike, you will not be mistaken with the choice of two-wheeled transport.
In our salon there are mountain and road bicycles before you decide to choose a bike, we recommend using the bicycle rental service in Minsk.
