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".

Fork material

— Aluminium. In this case, aluminium is the simplest and most unpretentious option. Its advantages include light weight; on the other hand, in the absence of shock absorption, the steering wheel with such a fork is highly susceptible to vibrations, and in terms of durability, aluminium is somewhat inferior to steel.

— Steel. Another relatively simple option, which at the same time is considered more advanced than the aluminium described above, and is found even in fairly expensive pro-level bikes. This is due to the fact that steel is noticeably stronger and more durable, as it is not as susceptible to "metal fatigue". However such forks weigh a little more than aluminium ones.

— Chromium molybdenum steel. A type of steel that is more advanced than more traditional grades. Among the main advantages of such alloys are high strength and reliability; at the same time, due to such properties, individual elements of the forks can be made thinner, and the forks themselves can be made lighter than ordinary steel ones. The main disadvantage of Cro-Mo steel is the rather high cost.

— Carbon. Lightweight and high-strength carbon fibre forks effectively dampen small bumps in the road under the wheels of the bike and slightly spring on small potholes, thereby providing cushioning on bumpy roads. The carbon fork facilitates the design of the front of the bike. Most often it is found on board "highways" and "gravel roads", less often it is installed in o...ff-road fatbikes. Vulnerable point — carbon forks break under the influence of strong point impacts.

Tyre

Tyre model supplied with the bike as standard. Different tyres have different purposes and characteristics; knowing the tyre model, you can clarify these points and check how they correspond to your wishes. This is especially important when choosing a machine for serious cycling.

Rim

Varieties of rims are determined by the number of horizontal jumpers in the design.

— Single. The simplest type of rim, similar in cross section to the Latin letter U. It is used mainly in entry-level bicycles.

— Double. Such a rim differs from a single rim by the presence of an additional horizontal bridge. Figuratively speaking, it resembles the same letter U, but with a double bottom. The features of this design are such that it is able to provide increased strength even with less weight than a single one. On the other hand, double rims are more difficult to manufacture and therefore more expensive. They are used primarily in bicycles where high resistance to stress is required — in particular, mountain varieties (see "Intended use") for freeride and cross-country.

— Triple. A further development of the idea of a double rim is a design with two additional horizontal bridges. This provides even greater strength, however, the weight increases quite noticeably. In addition, initially the second jumper was provided to strengthen the side surface, in order to avoid damage during the operation of rim brakes (see "Front brake", "Rear brake"); however, today most powerful brakes are disc brakes, and this problem is losing its relevance. Because triple rims are quite rare.

Front hub model

The model of the hub used in the front wheel of a bicycle.

The hub is the central part in the wheel through which the axis of rotation passes. Features of the behavior of a bicycle depend on its characteristics, in particular, “rolling” (the ability to move by inertia, without pedaling). Knowing the model of the front hub, you can clarify its characteristics according to the manufacturer's documentation, find reviews from other users, etc., in order to determine how this model suits you.

Rear hub model

Model of the hub used in the rear wheel of a bicycle. See Front Hub Model for details.

Bottom bracket model

Model of the carriage installed on the bike as standard. The bottom bracket is the part that connects the system (front sprockets with pedals) and the frame; roughly speaking — an axle with bearings.

For details on the meaning of the model of a particular part, see "Cassette Model".

Chain model

Model of the chain supplied as standard with the bike. For details on the value of the Model parameter for any part, see 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.
