Model year
The year to which the manufacturer classifies the bicycle (more precisely, the model range that includes this model).
The significance of this parameter is that the model range is updated every year, and two bicycles with the same name, but from different years, can differ significantly in characteristics and equipment. At the same time, new models (
2024,
2023) usually cost more, and older ones (
2022,
2021, etc.) are sold at reduced prices.
It is worth considering that a later year of manufacture in itself does not necessarily mean more advanced characteristics - manufacturers can change them in the direction of simplification. So
the model of previous years may be in no way inferior to the new bike.
Max weight
The maximum load allowed for a bicycle is, in other words, the maximum weight that it can normally carry in normal use. Of course, when calculating the load, the weight of both the cyclist himself and the additional load that he carries with him is taken into account.
The permissible load must definitely not be exceeded: even if the bike does not break down immediately, off-design loads can weaken the structure, and an accident can occur at any time. Also note that it is desirable to have a certain weight margin — at least 15 – 20 kg: this can be useful in case of transporting heavy loads and will give an additional guarantee in emergency situations (for example, when a wheel gets into a pit). Considering that the average weight of an adult is about 70 – 80 kg, bicycles with a permissible load
of up to 100 kg can be classified as "lightweights",
from 100 to 120 kg — to the middle category,
more than 120 kg — to "heavy trucks".
Speeds
The number of speeds (gears) provided for in the design of the bicycle. Each transfer has its own so-called gear ratio — in this case it can be described as the number of revolutions that the driven gear (rear, on the wheel) makes in one revolution of the leading gear (associated with the pedals).
Different gear ratios will be optimal for different conditions: for example, high gears provide good speed, but are poorly suited for overcoming obstacles, because. the effort on the pedals increases significantly and the frequency of their rotation decreases. It has been scientifically proven that a cyclist develops maximum power at a cadence of about 80-100 rpm. Thus, the presence in the bike of several speeds allows you to optimally adjust it to different driving modes and features of the tracks in order to provide optimal pedaling force and frequency of their rotation. For example, on smooth asphalt it is best to drive in a high gear, and when overcoming a rise or entering a dirt road, you can lower it in order to effectively overcome resistance.
The number of gears in classic systems is directly related to the number of stars of the system (on the bottom bracket with pedals) and the cassette (on the rear wheel); it can be obtained by multiplying two numbers — for example, 3 stars of the system and 6 on the cassette give 18 gears. However, there is also the so-called planetary hubs — there are stars one at a time, and gear shifting is carried out by a mec...hanism built into the rear hub.
Note that the optimal number of gears depends on the purpose of the bike (see above), and it is not always necessary to have several of them. So, in mountain models, depending on specialization, there can be from 8 to 30 gears, in road ones — within 20-30, and some inexpensive city bikes and most BMXs do not have a gear shift system at all.
Freewheel cogs
The number of stars (gears) of different sizes in a bicycle cassette. A cassette is a part of the rear hub that interacts directly with the chain, in other words, a gear or a set of gears mounted on the hub. In classical gear shifting systems, the number of gears directly depends on the number of stars in the cassette (for more details, see "Speeds"); a single chainring is used either in single speed bikes or in planetary hubs (see System Stars for more on these).
Freewheel/cassette model
Model of a cassette — a system of rear wheel gears — mounted on a bicycle. Cassettes of different models differ in characteristics and can belong to different classes — from entry-level to professional. Knowing the cassette model, you can get acquainted with its features in more detail (according to official documentation, reviews, user reviews, etc.). This is especially important when choosing a bike for professional cycling.
Rear derailleur
Model of the derailleur (derailer) installed on the rear wheel cassette as standard on the bike. For more information on why you need to know the model of a particular bicycle component, see paragraph "Cassette Model".
Shifter type
Type of shifters — devices that control gear shifting — installed on a bicycle. To date, the following types of shifters are used:
— Trigger. The design of this type is based on the use of 1 or 2 levers, as well as (sometimes) buttons located in close proximity to the hands of the cyclist. Trigger shifters can have different designs with varying degrees of convenience (usually, this is directly related to the price category of the device), located above or below the steering wheel, however, a number of common features are characteristic of all such models. Their main advantages are the traditional design and comfort when holding the steering wheel — the shifters are located outside the handles (grips) and do not affect convenience. In addition, they are quite simple in design and installation. On the other hand, this type also has a number of disadvantages. Thus, the presence of protruding parts increases the risk of equipment failure or injury to the cyclist in an accident. In many models, especially the low-cost level, in some cases, you have to take your hand off the steering wheel to change gear, which can lead to loss of control. In addition, shifting gears more than 2-3 "clicks" per press in trigger shifters is somewhat difficult and requires skill. However, in most cases, these disadvantages do not play a decisive role, and this type of levers is by far the most popular.
— Grip shift. By design, the grip shift is somewhat reminiscent of motorcyc
...le gas regulators: part of the handle is made movable, and gear shifting is carried out by turning it in one direction or another. Since the grip shift rings are actually combined with handles (grips), you don’t need to remove your hand from the steering wheel to control the gears — just move it a little to the side, and you can switch speed (and in some cases you can even keep your hands on the rings all the time). Such systems are devoid of protruding parts, which increases reliability and safety. Another advantage over triggers is the ease of shifting gears to any number of speeds. The main disadvantage of this type is the increased risk of accidentally shifting gears on a difficult section of the track, when you have to hold on tightly to the grips (especially with large palms and short grips) — you can accidentally turn the shifter, which is fraught with a sharp shift, breaking the chain from the sprockets and loss of controllability. In addition, contact with water or dirt on the ring can lead to slippage of the hand when working with gears, and the rings themselves increase the dimensions of the steering wheel and for some may cause inconvenience in the grip.
— Dual control. An original system that combines the control of brakes and gears in one lever — the brake lever. In this case, braking is carried out by moving towards you, and gear shifting is carried out by shifting up or down. The advantages of such a system are the constancy of the grip of the steering wheel — 2 fingers are enough to control both the brakes and the gears. At the same time, dual control shifters are quite complex in design, as a result, they are expensive and poorly compatible with “non-native” brakes and switches. And the ergonomics of such systems is very ambiguous, ease of use largely depends on the individual tastes of the cyclist. Therefore, this type of shifters is rather uncommon.
— Electronic. The competitive advantages of electronic shifters include the absence of a cable and levers to transfer physical force to the switch. In fact, these are ordinary buttons that send signals to the gearshift control unit. Such shifters work in conjunction with electronic switches that are installed on board advanced bicycle models. They can be placed in any convenient place with quick and comfortable access to the switches.Shifter model
The model of the shifters (see “Shifter type”) that are fitted to the bike as standard. For more information on why you need to know the model of a particular bicycle component, see paragraph "Cassette Model".
Equipment
Additional equipment supplied with the bike.
—
Wings. Protective devices in the form of shields that are installed over the wheels and protect the cyclist and others from water and dirt flying from the wheels while riding. Usually, they are made removable — in case you need to minimize the weight of the car.
—
Saddle with springs. A saddle equipped with springs that make it softer and provide cushioning. Note that soft spring-loaded saddles are designed mainly for a calm, leisurely ride — for high-speed bikes (including advanced road bikers), narrow hard saddles are considered more suitable.
—
Shield on the chain. Protective shield covering the bicycle chain. Note that the dimensions and design of such a shield can be different: in some models it covers the entire upper section of the chain from the front to the rear sprocket, in others it protects only the front sprocket itself from the outside. Anyway, the main task of such a device is to protect the chain from foreign objects, primarily the edges of the cyclist's clothing. The shield can be made removable — in case you need to reduce weight.
—
Footboard. A device in the form of a small folding pin that provides additional support. With a footrest, the bike does not need to be leaned on a pole, wall, fence, etc. — it can be placed vertically on an
...y relatively flat surface. Note that many bikes without a kickstand allow you to buy and install it separately.
— Peggy. Special devices installed on the axles of "stunt" bikes — BMX or mountain bikes of the corresponding specialization (see "Application"). Pegs look like extensions of axes pointing in both directions. The standard size of one such "continuation" is 11 cm in length and 4 cm in diameter. They are used for a variety of acrobatic routines, ranging from riding on pegs to sliding on edges, railings, etc.
— Boot. A classic bike rack is a platform for carrying various cargoes, mounted above the rear wheel. It is found mainly in city bikes (see "Application"), as well as some relatively simple mountain and road models. Separately, we note that it is at least highly discouraged to carry passengers on the boot, and in many countries it is expressly prohibited by traffic rules.
— Front boot. Boot (see above), located above the front wheel. The advantage of this arrangement is that the transported luggage is constantly in front of the cyclist's eyes. On the other hand, the front rack is usually attached to the steering wheel and turns with it; thus, the additional load can significantly complicate management. Therefore, this feature is relatively rare, usually as an addition to the traditional (rear) boot; the exception is tourism models (see "Application").
— Basket on the steering wheel. A basket for transporting various goods, installed in front of the steering wheel, above the front wheel; a kind of analogue of the front boot described above. At the same time, on the one hand, the basket is more massive, on the other hand, it is better suited for transporting large items or numerous small items. In addition, the cargo on the boot needs to be additionally secured, while this is not always required for the basket.
— Signal / call. A bell or other sound signal — for example, a horn — usually mounted on the steering wheel, at the cyclist's hand. This equipment is very useful for warning other road users of an approaching bicycle. And in some countries, the presence of a sound signal is mandatory according to traffic rules.
— Lighting equipment. In this case, the presence of a headlight, a taillight, and in some cases, both at once, may be implied; specific configuration should be specified separately. Anyway, such equipment is indispensable for riding at night: it makes the cyclist visible to other road users, and the headlight also illuminates the road. In many countries, traffic rules expressly prohibit driving at night without lights.
— Bottle holder. Dedicated water bottle holder, usually mounted on the frame. It is more convenient to carry a supply of water with you on such a mount than to keep a bottle in a backpack, bag, on the boot, etc. Some bike models with this function are immediately equipped with a bottle, for others it needs to be purchased separately.
— Pump. The presence of the pump in the delivery set eliminates the need to buy it separately; in addition, the “native” pump initially fits the existing mounts, while problems may arise with a third-party one. Note that most often the kit comes with relatively simple and compact hand pumps; they are not designed for large volumes of work, but they can quite cope with everyday tasks like pumping a flat tyre.
