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".

Suspension

The presence or absence of a depreciation system on a bicycle, as well as the type of this system.

Without depreciation (rigid). In such models, the wheels are fixed directly to the rigid elements of the frame; there are no depreciation devices. Due to this, the design of the bicycle is simple, the weight is small, the cyclist feels all the features of the road topography as much as possible, and the maximum efficiency of pedaling is also achieved, which is important, for example, for road models (see "Destination"). At the same time, structural rigidity is a "double-edged sword". On the one hand, "feeling for the road" is important for BMX and some mountain models (see "Purpose"); on the other hand, the lack of shock absorption significantly increases the load on both the structure and the rider himself, leads to increased wear, fatigue and some risk of injury on rough roads.

Depreciation of the front fork (hard tail). The most popular type of cushioning in adult bikes (see "Age Group"), especially urban and mountain types (see "Purpose"). In accordance with the name, in such bicycles, the shock-absorbing device is installed only on the front fork, while the rear wheel is rigidly fixed. The presence of a shock absorber somewhat increases the weight of the structure and complicates its maintenance, however, the advantages of such a scheme significantl...y outweigh the disadvantages: hard-tails combine good handling, “road feel” and ride comfort, including and on rough terrain.

— Rear fork. Bicycles in which only the rear wheel is damped, while the front wheel is rigidly fixed. The rear shock absorber is designed to provide additional comfort when hitting various bumps, and the absence of a front shock absorber reduces the overall cost of the machine. This option is found mainly in urban models, including electric bicycles (see "Application"); in other varieties, the use of rear shock absorption is not practical.

— Two-suspension (full suspension). Bicycles equipped with shock absorbers on both wheels — a fork in front and a special suspension in the back. Such models are as comfortable as possible for driving on rough terrain, because. They dampen the vibrations felt by the cyclist best and provide the best grip on uneven tracks. At the same time, the presence of a rear shock absorber "eats" part of the energy coming from the pedals, and you have to spend more effort to ride. To avoid this, many two-suspension bikes can be provided with front and rear suspension lockouts (see below), but full suspension complicates the design anyway, increases its weight and price. Therefore, this type of cushioning is relatively rare, mainly in certain varieties of mountain bikes (in particular, for cross-country and freeride; see "Purpose").

Suspension type (fork)

Front fork suspension type (if available, see "Suspension"). All shock absorption systems in bicycles work in two directions: vibration damping (damping) and impact energy absorption (cushioning). Accordingly, they have two main components: a damper and a shock absorber. Depending on the design features of these elements, the following types of depreciation are distinguished:

Spring-elastomer. In this case, the role of a shock absorber is played by an elastic spring, and the role of a damper is played by a rod made of an elastic, well-compressible material, the so-called elastomer. This type appeared as a development of conventional spring damping systems, it is more durable, but poorly suited for low temperatures — the elasticity of the elastomer in such conditions decreases, which negatively affects the characteristics of the system.

Spring-oil. Systems using a spring as a shock absorber and an oil cartridge as a damper. This design is somewhat more resistant to low temperatures than spring-elastomer, and in general has quite good characteristics, due to which it is quite widely used in various types of bicycles. The main disadvantage is the higher (on average) cost.

Air-oil. Combined systems consisting of an air cylinder that acts as a shock absorber and an oil cartridge that acts as a damper. They appeared as a development of “pur...e” air systems, which had a serious drawback: even with high-quality maintenance, the seals wore out rather quickly, which could disable the shock absorber. Air-oil systems are more durable and easier to maintain, while being quite efficient and weighing little. The latter is especially valuable for cross-country (see "Purpose"), where it is required to combine depreciation with a low weight of the machine.

Wheel size

The nominal diameter of the bicycle wheels. Usually, this paragraph actually indicates the size of the bicycle tyres supplied in the kit, more precisely, the outer diameter of the tyres.

Wheel diameter is traditionally indicated in inches. For bicycles of different purposes and age groups (see paragraphs above), there are certain size standards. So, adult mountain models are equipped mainly with 26 " wheels, "road" and urban ones — with a slightly larger diameter (mostly 28 "), and BMX for the most part — much smaller; children's and teens' bikes have smaller wheels than similar adults' bikes.

Other things being equal, larger tyres hold speed better and work out small bumps on the road; and relatively small wheels are more “sticky”, they provide more torque and better traction. This is the reason for the above-described difference in wheel sizes between bicycles for different purposes. Such nuances will be useful if you choose a car from several models with similar characteristics, but different wheel diameters. Here it is worth considering the features of the planned application. For example, for urban and "road" driving — on a hard surface without any special irregularities and elevation changes — it is better to choose larger wheels, and for dirt roads with ups and downs — smaller ones.

Also note that tyres are replaceable, and many bikes allow the installation of tyres of...a “non-native” size — for example, 29 "on a model with 28-inch wheels. It is also worth considering that wheels (tyres) of the same size may differ in inner (landing) diameter These nuances are described in detail in special sources.

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.

Battery capacity

The capacity of the battery that the e-bike is equipped with (see "Application"), expressed in watt-hours.

The main modern unit of capacity is the ampere-hour, but this designation is not entirely reliable: the actual capacity of the battery is determined not only by ampere-hours, but also by the operating voltage. In fact, this means that two batteries with the same Ah and different voltages will have different actual capacities. In order to take this nuance into account, the designation in watt-hours was introduced: it is as reliable as possible, in terms of capacity in Wh, you can compare batteries with any nominal voltage. In this case, Wh can be converted to Ah and vice versa using a special formula if the battery voltage is known.

See "Battery Capacity" above for details on capacity in general.

Motor power

Power of the motor installed in the e-bike (see "Application"). Models with all-wheel drive (see below) equipped with two engines usually list the total power.

In general, the engine is selected by the manufacturer in such a way as to provide a certain maximum speed and mode of operation. So when choosing, you should pay primarily to these characteristics, and engine power can be considered more as a reference parameter. If we talk about differences in power, then a more powerful motor, on the one hand, allows you to develop higher speeds, accelerate faster and overcome steeper climbs. In addition, high power, by definition, is needed for full-fledged electric traction (see "Operating mode"). On the other hand, an increase in power significantly affects the price, weight, and most importantly, the energy consumption of the motor; the latter, in turn, requires the use of capacious batteries. Modern electric bicycles can be divided according to this indicator into two categories — up to 250 W inclusive and more than 250 W.

Full charge time

The time required to charge the ebike battery (see "Application") from zero to 100%. This parameter allows you to estimate how long breaks you will have to take to replenish your energy supply. However, even in the slowest models, this time does not exceed 8 hours — this allows, for example, to drive during the day and put the battery on charge from evening to morning.

Battery arrangement

Location of the battery in the e-bike (see "Application").

Framed (hidden). Placing the battery inside the bike frame. The advantage of this installation is that the frame provides additional protection for the battery. The main disadvantage is that the frame has to be made quite large, which accordingly affects the weight of the machine. In addition, access to the battery with this installation is difficult, removing it, if necessary, is quite difficult.

On the frame. Installing the battery directly on the frame — usually above the down tube. It is this installation method that is the most popular nowadays and is considered the most convenient: the battery is located in a space that remains unused when using a bicycle, and does not interfere with installing various additional equipment on the car (headlights, boots, etc.). In addition, with this placement, the additional weight is distributed in an optimal way; and the battery itself, unlike installation in the frame (see above), remains easily accessible and, if necessary, can be removed without problems.

On the boot. Installing the battery on the boot — in a container under the boot platform or in a special case suspended from the platform. This option is quite functional in itself, besides, it automatically means that the bike is equipped with a rack. On the other hand, not every...car needs a boot; and the presence of a massive battery in the area of the rear wheel complicates the transportation of goods (especially heavy ones).

Under the saddle. Installing the battery under the saddle — usually on the seat tube of the frame from the side of the rear wheel. Such an installation puts forward some specific requirements for the frame design, so it is found mainly in rather non-standard varieties of bicycles — in particular, fat bikes (see "Application") with a lower frame, as well as compact urban models with small wheel diameters and a special frame configuration.
