What keys are needed to assemble a bike

Packing dimensions for large

Due to the design characteristics of the bike (type of bike, frame volume, wheel size), the volume of its box may not be the same. Having information about the volume of the box, you can find out the price of delivery of the bike by various courier services or choose a car for transportation.

Bicycle from the box: dimensions, assembly, tools

Great packed in a cardboard box. a particularly popular and budgetary method of delivering bicycle transport if you use courier delivery services.

To assemble a large one, the consumer will need about 20 minutes, and the work itself will not be particularly difficult.

  • How the shipment is carried out is great?
  • How the bike will be packed and to what extent will it be disassembled?
  • Is it difficult to combine the bike after I have the package?
  • Will there be any difficulties with the guarantee and further service??

Below we will try to deal with all the points, and besides, we will dispel the myth that getting a big one in a box is very risky and not cheap at all.

Assembling children’s bicycles from the box

The packaging of bicycles for children is almost the same as for adults, in addition to the size of the packaging itself. When buying a 12-20 ”child bike, you may need to put special support wheels on the sides, which should not be too difficult, but you will need to carefully read the instructions, because different manufacturers use fastening types that are completely different from each other. In addition, it will be necessary not to be lazy over the design of the fenders, trunk, basket and other additional accessories, if they are in the set.

At the time of installation of the baby’s bike, we advise you to check all parts of the structure, because the parts could break off during transportation or be insufficiently secured in production. Be sure to tune the braking system.

Cycle packaging classification and conditions under which they are used

To save space while transporting and preserving bicycles, many manufacturers use specialized shipping boxes. This makes it possible to reduce the price, due to the reduction in size, and in addition, to protect the large from possible defects. Taking into account the manufacturer and the direction of delivery, 2 types of packaging are used:

Assembling your new mountain bike with minimal tools

  • CKD. ​​frames and components are packed separately, and upon arrival in the country of destination, they are assembled at the nearby factories. Further, in a personal box, each large one is sent to the consumer. A similar delivery method nowadays comes across very rarely and often when transporting inexpensive modifications.
  • SKD. This method of packing bikes is considered the most popular and is used to transport the best branded bikes. First, the layout is large in the country where the production forces of the company are located (China, Taiwan and others). Then a comprehensive regulation and monitoring of the readiness of all departments is carried out.

Directly, on the eve of delivery to the country of destination, the most weighty components (front wheel, steering wheel, seat and pedals) are removed from the bicycles, which makes it possible to significantly reduce the dimensions of the packaging for transportation. The packing of the frame and the separated parts is done very carefully in order to eliminate the possibility of damage during transportation.

keys, needed, assemble, bike

If we talk about more popular companies, then they try to do everything to make sure in the properties and serviceability of their product, and trust the assembly procedure only to branch factories (in some cases even with their own employees, which regulates the quality level). With this approach, the number of warranty breakdowns is significantly reduced, because specialists with great work skills and a special device are engaged in great work. Therefore, by purchasing a first-class branded bike, you can rest assured of its reliable pre-sale preparation.

The build is great off the box

We know that as soon as the cyclist was delivered a bicycle packed in a box, he probably wants to ride it as soon as possible, but an important task arises. to assemble the bicycle. If you think that you will need to complete the bike piece by piece, like a designer, there is good news. the manufacturer did this work for you more than 80%. You just need to open the cardboard, take out the bike and put the front tire, steering wheel, seat and pedals on it.

Before traveling, you still need to check the accuracy of the settings of all sections, and most importantly, the functionality of the brake system. Inflate the wheels when needed.

Now let’s analyze the assembly sequence in more detail:

  • Open the box carefully;
  • Take out all the elements and put them on an open plane;
  • Fix the steering wheel to the stem, fixing it with an eccentric;
  • Place and secure the seat;
  • Mount the front wheel into the fork and adjust the brake system;
  • Lock the pedals;
  • Pump up the wheels;
  • If necessary, install auxiliary devices;
  • Carefully inspect and test the basic bike assemblies.

Important! There is no need to apply arrogant efforts at the moment of tightening bolts or nuts, you can break the thread or disable the components.

The installation procedure is not that difficult. However, when problems arose or you categorically made a decision not to dig into the assembly of the bike. it is possible to use the services of a reliable bike workshop. The price of assembling a bicycle, as a rule, does not exceed 100 UAH, but this will make sure that your vehicle is assembled and checked by a qualified and competent specialist.

Assembly tool kit great with box

Women can also handle assembling bicycles out of the box. If any problems suddenly arise, you can always contact us, our employees will recommend where to find, how to screw, and what is the name of the thing that lies in the box.

Bicycle tool

List of bicycle tools that are desirable to have for most repair and adjustment work in the street, home or garage.

When choosing a bicycle tool for yourself, it is important to pay attention to quality. It is better to buy an expensive tool, it will last longer and serve better. It is difficult to unscrew a stubborn screw with a cheap, low-quality screwdriver, but it is very easy to rip off the slot.

Screwdrivers, hex keys, ring, open-end, adjustable wrenches.

But some bicycles may require a size 10 Allen key, so a car key set at home or in the garage will still be fine. And it is more convenient to work in stationary conditions with car keys, since they have longer handles.

At home, it is also a good idea to have a set of open-end or spanner wrenches up to 16mm in size, and if your bike does not have quick-release clamps, then you should carry several of these keys of a suitable size with you, or use a family type key. (It is inconvenient to use the family key at home. It is short and cuts into your hands.) An adjustable wrench is needed less often, but it doesn’t hurt to have one either. If the wheels on your bike can be removed without the use of tools, then it is not necessary to carry it with you. But at home it is highly recommended to have a large adjustable wrench (32 or 40 mm). In a modern bicycle, many parts are made of aluminum alloys, which have the unpleasant property of sticking tightly. In cases where neither kerosene nor swearing does not help, a large key can come in handy (along with a sufficiently powerful vice).

If the bike has disc brakes, then you must also have PHILIPS keys.

If you can remove the tire from the rim with your hands, then you can do without them. If the tires are tight, and the fingers are far from the pliers in compression force, then a couple of mounts should always be carried with you. picking the tires with screwdrivers is not recommended. A car bike mount doesn’t fit well. Bicycle keys often include plastic pry bars, which are easy to carry around. And at home you can have such metal mounts. better a few.

“Eights”. the most common rim disease. Even the best rim, with very careful riding, will still have an eight after a while. If it is not strong, then you can be patient, but with the Big Eight (for example, after falls) it is not always possible to ride. Especially on bikes with V-BRAKE brakes. the pads start to rub against the rim.

keys, needed, assemble, bike

Therefore, the key for the knitting needles should also be constantly carried with you. A similar key is poorly suited for domestic bicycles. it only damages the spoke nipples.

This kit includes patches, glue, and a skin. It is highly recommended to carry it with you.

From Box To Bike: How To Assemble A Brand New Bicycle

On many bicycles, the chain is one-piece, and a special tool is required to remove / replace it. squeeze. It allows you to disconnect and connect the chain links. If your bike has a split chain, then a squeeze is not needed. You should have this tool at home and do not need to carry it with you (except for long journeys).

You must have two such keys. They are designed for disassembly, assembly and adjustment of wheel hub bearings. It is impossible to replace such a key with an ordinary open-end key. the open-end wrench is thicker. As a last resort, you can use the family key.

Most modern sports bicycles have a square bogie axle, and the cranks are fitted onto the axle and attracted by nuts or screws. No special tools are required to install the connecting rods other than a wrench. A special tool must be used to remove the connecting rod. puller.

On some types of carriages (OCTALINK standard), the axle is hollow and has a circular cross-section (In nature, there is a third standard of connecting rods and carriages, called ISIS. It is similar to OCTALINK, but incompatible with it. It needs its own puller).

On many modern sports bicycles, the carriage assembly is non-separable and maintenance-free. To install and remove it, you need a special slotted wrench. Sometimes, instead of a slotted wrench for the carriage assembly, you need to use a wrench of this shape.

And this may be required. It can be replaced with a regular 36 mm open-end wrench, or, as a last resort, an adjustable / gas wrench can be used. The gas key must be used carefully. the frame can be easily damaged.

If the carriage assembly is collapsible, then it must be adjusted and disassembled using such a key. Although, as a last resort, you can get by with the family key.

Tool for maintenance of cassette and ratchet

The need to remove the cassette arises quite often. For example, when adjusting the rear wheel hub, or when replacing a spoke from the cassette side. To remove and install the cassette, you need such a puller. Which puller to buy. depends on what type of rear hub is used on your bike. For a hub with a screwed-on ratchet, use the one in the photo on the left. For SHIMANO bushings. one of the others If the hub axle is hollow, then it is better to purchase the one on the right (with a guide axle)

When removing the cassette, there is a problem of holding it, because you have to unscrew the cassette in the direction of free rotation of the rear wheel. Such a whip is used to hold the cassette. You can make it yourself from a bicycle chain. As a last resort, you can use a car oil filter remover.

Wire cutters are needed when replacing brake cables and derailleurs. The same nippers can press the tip onto the cable. With ordinary pliers it is impossible to neatly bite the cable. it flattens and then begins to unravel. If there are no wire cutters, you can carefully saw off the extra piece of cable from the angle grinder, and press the tip onto the cable with pliers. You can get out of the situation with a sufficiently powerful soldering iron. just tin the end of the cable.

How to assemble a bike out of the box

Buying a new bike is always accompanied by great joy and anxious anticipation of the first ride.

Perhaps, at first glance, this procedure will seem complicated and impracticable. But, after carefully reading this article, you can easily assemble and configure the bike yourself. This skill will be useful to you in the future, when the question of emergency repairs arises away from home.

  • Hexagon set (multitool);
  • Screwdriver;
  • Open-end wrench 15;
  • Auxiliary tools (nippers, stationery knife).

Advice: choose a high-quality multitool with a large number of all kinds of keys! Thus, with a single tool, it will be possible to set up and repair any part of the bike. Another significant advantage of the multitool will be the presence of a squeeze for the chain.!

So, the box with the bike is in front of you, all the necessary tools are at hand. it’s time to start assembling!

If you can ask familiar cyclists for a special rack-bracket on which you can place your bike, this will be an additional convenience during assembly. In case of her absence, just use the help of friends or relatives.

First of all, you need to inflate the wheels according to the recommended pressure. Select an average between the upper and lower pressure thresholds printed on the tire. With some experience, you yourself can easily determine the degree of pumping, depending on the complexity of the relief. In rare cases, if the bike is equipped with disc brakes, the brake rotors need to be screwed onto the wheels. They are attached with six special bolts that come with the bike.

READ  What should be the height of the bike

Tip: A quality telescopic bicycle pump is lightweight and compact. It can be easily positioned on the frame using a special mount. Better to give preference to a pump with a pressure gauge. This way you can more accurately regulate the pressure in the tires, thereby extending their service life.

You need to start assembling the bike by installing the handlebar. To do this, you need to unscrew the stem cover, which is fastened with four bolts. Next, we insert the steering wheel into the stem, center it using the applied marks and press it with the lid. The stem bolts should be cross-tightened without excessive force. At the same time, you need to check how the stem bolts are tightened, with which it is attached to the fork stem. Tighten them if necessary.

An important point is the position of the brake levers on the steering wheel. They should be placed in such a way as to continue the position of the palms, without the need to bend them in the wrist.!

Next, you need to start installing the wheels. Often, manufacturers already at the factory install the rear wheel and adjust the speed switch, but there are also completely disassembled options. This procedure is best done on an inverted bike.

Depending on the level of the bike, the wheels can be attached to the frame using special eccentrics or nuts. In the first case, the installation procedure is done manually without tools, and in the second. you need an open-end wrench for 15.

To install the rear wheel, you need to pull the rear derailleur back, overcoming the spring force and inserting the wheel into special slots in the frame (dropouts). After making sure that the axle of the wheel lies flat in the frame, insert the eccentric into its hole, pressing the adjusting nut by hand and close the lever, thereby rigidly fixing the wheel. The pressing force of the eccentric lock or the tightening of the nut is calculated intuitively. It should not be excessive so as not to damage the components, but also not too weak so that the wheel does not fall out while driving. This procedure is carried out in the same way for the front wheel. You also need to take into account that the eccentric lever should be on the left side in the direction of the bicycle and look up in the closed position.

The next step is to install the front and rear brake calipers (the device into which the brake pads are inserted) onto the frame and fork. The fastening of these elements can be carried out in two ways. directly or using special adapters that come with the kit. In the second case, we first install them, and only then we fasten the caliper. To perform this procedure, you will need a 5mm Allen key and four matching bolts (included). After that, you can fix on the frame all shirts of cables or brake lines, which fit into special grooves and are attached using ordinary plastic ties.

Tip: When installing the calipers, be sure to align them with the brake rotors. This will eliminate the possibility of friction between the pads and the rotor, thereby ensuring free rotation of the wheels. To carry out this procedure, you need to slightly loosen the mounting bolts and press the brake lever several times, holding it after the last pressing. Without releasing the brake, tighten the bolts and check the ease of rotation of the wheel. If friction is present, then the manipulations must be repeated to obtain the desired result.

There is only a little left! Installing the saddle and pedals 🙂

Install the saddle so that it is strictly parallel to the ground, and its nose looks along the top tube of the frame, without deviation to the left or right.

When driving for the first time, it is very important to set the correct height and position.

To do this, use the following guidelines:

  • In a sitting position, an almost fully extended leg should reach the pedal with the heel;
  • In the position of the connecting rod parallel to the ground, the bent knee should form one line with the pedal axis, strictly perpendicular to the ground. This adjustment is done by moving the saddle forward or backward.

These tips will help you pedaling as efficiently as possible, while reducing overall fatigue, as well as eliminating the risk of knee injury while riding.

The pedals are set using a 15 open-end wrench. Note that the pedals are labeled R and L (left and right). This is how they should be installed on the connecting rods. The left pedal is screwed into the crank arm counterclockwise, and the right. clockwise. Often, after buying a new bike, it becomes necessary to adjust the rear and front derailleur. To do this, you can use a special article on our website. Once again, carefully inspect the bike, checking each installed component and if everything is ok. feel free to go on your first trip!

Required tools

Spoke key. serves to repair wheels, for example: fixing eights. An eight can appear on any wheel, especially if the rim is soft. At the same time, it is quite tedious and costly to contact the master all the time, and you can fix a small eight in five minutes.

Cassette puller, whip, adjustable wrench. this kit is needed to remove the cassette. If you want to clean the rear hub, cassette stars, replace the cassette, you can do it yourself. Of course, you can do without a whip, for example, use a towel or the chain itself, but this is not convenient and not aesthetically pleasing. Keep in mind that if you have less than seven stars, then most likely you have not a cassette, but a ratchet, then you will need another puller.

Forcing the chain. needed to shoot the chain off the bike. Even if you use a squeeze chain with a lock, you may still need it, for example, to shorten the chain length or if the chain breaks.

Mounting blades. not every tire can be removed with bare hands, then assemblies have to be used for these purposes. You can, of course, try to use the means at hand, but then there is a possibility of tearing the camera.

Cycling first aid kit. you cannot take an endless number of spare cameras with you, and the bike first aid kit does not weigh much, is not expensive and is easy to use.

This is a toolbox for basic bike maintenance.

Basic tools

The basic set of tools will allow you to carry out almost all repair work on the bike.

Pedal wrench. serves to remove the pedals from the connecting rods. You can try to use other keys for these purposes, for example, a 15-inch open-end wrench, but not all of them will be able to get into the gap between the pedal and the connecting rod. A special key is perfect for this, plus it will last a long time.

Connecting rod puller. is necessary for removing the connecting rods from the carriage axis. Pay attention, if your connecting rods are attached to the carriage on a “square”, then the nozzle of the squeeze should be narrow, and if the connection is “splined”, then there should be a wide nozzle at the end. And in Hollowtech systems, the connecting rod puller is not needed at all, there is enough key for the carriage cups.

READ  Can I park my bike in a common corridor

Carriage puller. spline wrench, required to remove the carriage.

Wire cutters. so that the ends of the cables do not dissolve, they must be cut only with special pliers, and then put on a special aluminum tip.

Cone wrenches. wrenches may be needed to clean and lubricate loose bearing bushings. Keep in mind if you are using industrial bearings then these keys may not be needed.

A set of Torx keys. sometimes, along with hexagons, such a standard is used in bicycles, so if you have such bolts, you need to purchase such a set.

Set for bleeding hydraulic brakes. special kits to help pump the hydraulics. You can try to make such a set yourself from a disposable syringe, but the finished tool is more convenient.

If you purchase all the tools from this list, then you can solve the vast majority of problems with the bike yourself, and contact the master in extreme cases and only for specialized work (such as servicing shock absorbers).

Special tools

These tools will make your home bike mechanic’s life much easier.

Rack for repair. holds the bike in a position that is convenient for you, then you do not have to sit in a bent position during repairs.

Wheeled stand. you can straighten the wheel on the frame, but at the stand it is more convenient, better and faster.

Strain gauge. allows you to measure the uniformity of the spoke tension. Essential for those who assemble wheels on their own.

Chain wear gauge. allows for timely replacement of the chain on the bike, this is necessary to extend the life of the cassette and system sprockets.

Magnetic saucer. holds in itself all small metal objects and prevents them from getting lost.

In the list there are also obligatory tools that will allow you not to get into a difficult position while riding them, it is desirable for all cyclists to have them. But there are also unnecessary things and they should be purchased only if you decide that you need them. Just guess what you might need. As you can see, not so many tools are needed to fully repair a bicycle, so a keen person, over time, will be able to collect everything he needs and forget the way to the workshop.

Disassembly and assembly of road bikes

Disassembly and assembly of a bicycle is necessary for maintenance, repair and conservation. Disassembly can be partial or complete. However, not every repair with certain skills and tools can be done at home or on the road.

The domestic industry produces first-class road bikes of various brands and types. The use of unified assemblies and parts allows for a unified procedure for disassembling and assembling bicycles.

It is not difficult to disassemble the bike “by cogs”. But assembling it so as not to break anything, not to damage anything and so that there are no “unnecessary” parts left is more difficult. Correct assembly of a bicycle and adjustment of its assemblies requires renowned skill and skill.

If you need a serious repair of the bike, as well as if you are not sure of your own strength, we recommend that you contact a specialized workshop.

Instruments. In addition to the tools included with the bike, a second combination wrench can be purchased. It will be needed in cases where two nuts are located on the same axis. One of them is easier to unscrew while holding the other with a key. Hold the head of the bolt well with a wrench. It is convenient to work with conventional wrenches, ball wrenches, adjustable wrenches, pliers. When disassembling wheels and connecting rods, you need a hammer, a file, a hardwood spacer, and a wooden stand from the connecting rod to the floor. Among the tools should be a nipple wrench for spokes, a cone wrench with projections for carriage tapers, a screwdriver.

Basically, all parts of the bike are disassembled with a wrench and screwdriver. A combination wrench is used for the steering column locknut and carriage locknut, the protrusion of which is inserted into the locknut groove. For the carriage cones, a cone wrench is used, the protrusion of which is inserted into the slots of the cones.

Workplace. For disassembly and assembly of the bike, you need to prepare a special workplace. All necessary tools, rags, grease, etc. should be at hand. Bicycle parts must be folded into a separate place b in the disassembly sequence.


REMEMBER THE PARTS INSTALLATION ORDER! When removing and installing wheels, guards, when working with a pedal carriage, turn the bike over and put it on the handlebar and saddle. The steering column and saddle are handled by placing the bike on wheels and leaning it against a wall or tree. With the wheels and carriage sprocket removed, you can put the bike on the front and rear (chain) forks.

Disassembly of individual assemblies (wheels, saddle, steering wheel, bushings, etc.) is carried out at a separate workplace so as not to lose parts.

keys, needed, assemble, bike

DO NOT USE SIGNIFICANT MECHANICAL FORCES AND HAMMER IMPACT when disassembling and assembling the bike! Disassembly difficulties are the result of inability and lack of skills, poor care, corrosion, contamination of individual parts, improper installation or breakage of parts. Assembly difficulties. a consequence of inability and lack of skills, incorrect installation of parts, lack of lubrication, the presence of unusable parts.

Serviceable, properly sized, clean and lubricated parts must fit freely, without excessive force. In case of difficulty during disassembly, it is recommended to moisten the junction of the part with kerosene or liquid lubricant, during assembly. check the correct installation and serviceability of the parts, remove dirt and rust, apply grease to the joints.

INSTALL THE WRENCH AND THE SCREWDRIVER CORRECTLY to avoid damaging the edges of the nuts and the splines of the bolt heads and tapers.

The threads in all threaded connections on the bicycle are right hand. The exception is the left crank arm and the right side of the carriage. Tighten nuts and bolts tightly, but do not over-tighten. Hand-felt play is not permitted in all mountings and rotary joints. Rotation should be free, without knocking, squeaking or jamming. During the operation of the bike, it is necessary to regularly check the tightness of nuts and bolts and the state of adjustment of the components.

A properly assembled and adjusted bike moves easily and quietly. Riding such a bike is safe and a real pleasure.

Carefully monitor the condition of the bike, repair faults in a timely manner, regularly lubricate and clean the bike from dirt and dust. Properly maintained, your bike can last a long time and reliably.
