Detailed instructions for assembling a bike vmx. How to assemble a children's bike out of the box

Despite the hefty price tag of road bikes, you still need to do some setup work when building it out of the box.

2. First steps

3. Rudder

4. Saddle

5. Brakes

6. Switching

6.1. "Pistols"

6.2. Switches

1. Tools

For assembly and configuration, we need some tools. I would like to say that each manufacturer may have different sizes hexagonal screw heads, or there may be “stars” in general, as in our case

1. Hexagons for 3, 4, 5, 6 mm.

2. Torx T25 ("asterisk").

3. Phillips screwdriver.

4. Side cutters or strong scissors.

5. A pump that allows you to pump high pressure (up to 11 atm, 160 psi).

6. Torque wrench (desirable, especially if the frame, handlebars, stem, seatpost are carbon).

2. First steps

The bike is in the box like this.

We remove the packaging

As a rule, bicycles are wrapped big amount packaging to preserve the paintwork, as well as "hide" the protruding parts so that they are not damaged during transportation.

1) Cut off the nylon clamps with side cutters and remove the packaging.

2) If there is a package wrapped with tape, it is better to remove it with your hands.

Inflating the wheels

Typically most road bikes have Presta valve tubes. For pumping, we take the pump, unscrew the valve, install the pump head and bring the pressure in the wheel to the one recommended by the manufacturer. You can find out the recommended pressure on the side of the tire.

In our case, you can pump up to 10 atm, but most tires have a maximum allowable pressure of about 8 atm.

3. Rudder

There may be 2 options

1) The stem is mounted on the fork stem, the handlebar is separate.

2) The steering wheel is fixed to the stem, instead of the stem there are spacer rings on the fork stem.

We have the first option.

We recommend loosening the stem, removing the cover and checking the tightening of the reusable anchor, which is placed in forks with a carbon stem. If there is a torque wrench, then it’s good (the value of the tightening force is written on the anchor), and if it is not there, then the main thing is not to tighten it “from the foot”

After setting the anchor, place the stem on desired height and press the lid on top. Only then can the screws on the side of the stem be fixed.

As a rule, the length of the fork stem on new bikes comes with a margin, but do not rush to shorten the stem immediately. First you need to ride and understand in which position of the takeaway you are most comfortable riding. Based on this, it is already possible to cut the stock.

Fix the handlebars in the stem so that it is parallel to the surface on which the bike is standing (when the “guns” are not pulled up and not lowered down). Tighten with screws evenly in turn

With winding, too, there may be a surprise. Some manufacturers save on assembly by not wrapping the steering wheel, since the process takes a lot of time. We are lucky - there is a winding

But if you have it separately in a box, then do the following

1. Start wrapping the handlebar from the ends, making a slight overlap on the holes in the handlebar.

2. Wrap at a slight angle.

3. When the winding is finished, fix it with the supplied adhesive tape. Better wrap it with electrical tape, because the tapes do not always securely fix the edges of the winding.

4. Insert the plugs that come with the kit into the holes of the steering wheel. We needed the overlap of the winding in order for the plugs to hold firmly in the holes of the steering wheel.

5. Make a winding next to the “gun” mount, as in the photo. So the plastic parts will not protrude from under the lining

4. Saddle

Place the saddle on the seatpost so that when the seatpost is inserted into the frame, it is parallel to the surface on which the bike is standing.

Adjust the saddle so that it sits in the middle of the mount on the seatpost. In the future, you can build on your feelings and install the saddle the way you want.

Both of the above steps are done with the screws on the seatpost.

The height at which you need to install the seatpost will also become clear after the first trips. In the future, if you are very concerned about the weight of the bike, the pin can be shortened, but note that at least 10 cm of length must remain in the frame

5. Brakes

Before adjusting the brakes, set front wheel. The brakes, at the same time, must be disengaged, for which a separate lever is responsible. After installing the wheel, the lever must be turned to the lower position.

Also check that rear wheel was set correctly. If it is not level, put the bike on the floor, loosen the cam, push down on the saddle, tighten the cam

The eccentric lever must always be closed! It is forbidden to screw it all the way in and drive in the open position of the eccentric!

In our case, conventional road caliper brakes are mounted with a bolt into a special hole in the fork.

As we can see, the brake is "littered" on one side.

A rough adjustment is to rotate the brake slightly on the bolt shaft so that the pads are about the same distance from the braking surface of the rim.

The next step is to use a 3mm Allen key to adjust the position of the brake levers so that the pads are equidistant from the braking surface of the rim

If the pads are a little tangled, use a 4mm Allen key to set them parallel to the braking surface of the rim.

Adjust brake force with cable tensioner

6. Switching

6.1. "Pistols"

First you need to understand how "pistols" work.

Responsible for the rear derailleur "pistol" with the help of a small lever upshifts

With the help of the brake lever turned to the side, the gear is lowered (if you press further, you can switch 2-3 gears in one “long” press)

Responsible for the front derailleur "pistol" has some features. To begin with, let's say that a small lever drops the chain onto a small star

Accordingly, a large lever in the form of a brake handle puts a chain on a large star

However, in each case there are small “gun” strokes that provide protection against large chain distortions for the derailleur and due to which the chain will not rub against the frame.

1. Let's say the front derailleur is in the leftmost position, the chain is on small stars both in front and behind. In this case, you need to press the brake lever of the left "pistol" to the side until the first small click, which will lock the switch in a position in which the chain does not rub against the frame.

2. Once again pressing the handle, but not bringing it to the stop, the chain will switch to a large star, but will still rub against the derailleur frame. In this position, you can use a large chainring in front and a large chainring in the rear, since this position of the front derailleur allows the chain to work with such a misalignment.

3. Bringing the handle to the end, you will eliminate the friction of the chain on the frame when there is a large star in front and a small one in the back.

4. In reverse order everything works exactly the same, only to drop the chain from a large star to a small one and to eliminate distortions, you need to work with a small lever.

6.2. Switches

The rear derailleur is set up correctly in most cases and requires only minor adjustments.

1. Install the chain in front on the largest star, and in the back on the smallest one. Check that the star and rollers are in line.

2. Place the chain on the front of the small chainring and on the back of the largest one and check that the chainring and rollers are in line.

3. If this is not the case, and even more so if the chain falls into the spokes or onto the frame, use a Phillips screwdriver to adjust the position of the switch with the stop screws.

4. After that, check that the switching is clear, and if it is not, use a hollow bolt to adjust the cable tension.

Do the same for the front derailleur. Switching limits are also regulated by screws "L" and "H"

The only thing, in our case, the role that the cable tensioner used to play is played by this screw

Pedals road bikes not included, so first choose the pedals you need, then read our article "" and act.

As a result of the assembly, such a handsome man turned out

The video perfectly complements our article, since the road bike here is assembled almost from scratch.

First of all, it should be noted that assembling a bicycle out of the box is a delicate matter, which will require a lot of skill, time and effort, unless, of course, you are a professional. So, if possible, entrust this matter to someone who understands such subtleties. This ensures that all the necessary nuts are tightened in a clockwise direction, and the brake lever is fixed exactly where it is needed.

But if you still decide to assemble the bike yourself, we will be happy to help you do it right.

Why is the bike disassembled?

So, let's talk about everything in order. Why take the bike apart and put it in a box at all? There are at least two reasons. Firstly, it allows you to significantly save on its transportation. And secondly, in this way you can protect the bike from various damages that simply cannot be avoided during transportation.

What is included?

In the box, as a rule, there is an incompletely disassembled bike. Wheels, pedals, fenders, saddle, steering wheel, mirrors, horns, reflectors are located separately from the frame. The connecting rod and brake lever will also have to be installed additionally.

Unboxing

We talked a little about what the kit is, now it would be nice to talk about unpacking: we won’t assemble the bike right in the box. It is better to unpack it in a strict sequence:

1. The first step is to carefully remove everything from the box, separately arranging all unassembled elements, including the frame, wheels and brake lever;
2. Further, cardboard must be removed from all elements, and packaging from the frame (if, of course, there is one);
3. All films and packaging are needed exclusively for transportation, so they need to be disposed of so that they are not confused. The protective plastic packaging must be removed from the axles;
4. Well, in the end, it is important not to forget to rewrite in the warranty card, which is also included in the kit, serial number frames.

Assembly

Before proceeding with the assembly, you need to take care of the inventory - you will not assemble the bike with your bare hands. Moving the bolts clockwise will be much faster if you have the right key. So what tools do we need?

1. Screwdriver. Trite, but without it - nowhere. It is highly desirable that it be neither too large nor too small. All the bolts that need to be tightened clockwise on the bike are not large;
2. Pliers. Pliers - reliable assistant in the matter of assembling anything;
3. Specialized pedal wrench. Here, of course, you can get by with a 15 mm open-end wrench;
4. Hex keys: 4.5, 6 and 8 mm;
5. Wrenches for 6 and 10 inches.

Threaded connections require attention

In general, this will be quite enough - now you can start assembling. Just before we remind you that you need to carefully check all fasteners and threaded connections, because assembling a bicycle is a delicate job that does not tolerate the use of rough physical strength when rotating clockwise. It is better to clean the thread ten times than to damage anything.

Now, actually, about the assembly in order.

Wheels and brakes

It is best to start the assembly with the wheels, it is advisable to adhere to the following sequence:

1. If the front wheel has any marks, it is important to determine its direction. If they are not on it, then it does not matter in which direction to fix it. When inserting the front wheel into the fork, care must be taken to ensure that it clearly falls into the grooves;
2. When mounting the eccentric in the bushing axle on the front wheel, you need to make sure that the springs are on both sides of the bushing, and the eccentric foot is on the left side;
3. At the end, the eccentric foot should be fixed parallel to the wheel axis, it should be fixed so that the wheel is securely fixed, but the main thing here is not to overdo it.

After the wheels are done, you can move on to the brakes. And we'll start with the brake cable. Before inserting the cables into the shirts, it is highly desirable to lubricate them. If there are wheels rim brakes, they need to be fastened. You also need to pay attention to the brake lever: it is important that the levers are located symmetrically.

Shifters and steering column

Particular attention should be paid not only to the brake lever, but also to the gearshift knobs. Their cables also need to be lubricated before being "dressed" in the shirts intended for them. You don’t need to screw them all the way down, this will help, for example, at the time of a fall: the shifter will not break, but only turn slightly.

The steering column has one feature: as a rule, it is already installed on a bicycle. But this feature of hers does not prevent us from paying a little attention to her. First of all, the surface of the steering column should be lubricated with grease. It is also important to carefully press the cups of the steering gear.

The steering wheel in the takeaway must be fixed symmetrically, so that the brake levers are lowered down at a certain angle from the horizontal, namely about 40 degrees. It is also important to hang the cables correctly so that they do not get confused, and of course, it is important not to forget to secure the steering wheel well. This will help prevent falls and injuries in the future.

Pedals

There is absolutely nothing complicated in installing the pedals, it is only important to reckon with some subtleties. For example, you need to take into account the fact that the pedal must be twisted against the direction of movement of your bike. Just with this in mind, each pedal (both the right and the left) has a thread in different sides. Therefore, it is important that each of them is in its place. The right pedal must be twisted clockwise, and the left - vice versa. Otherwise, nothing will come of it. For these purposes, which is quite obvious, a hex key is used. In the matter of pedaling, you can already forget about tenderness and caution - the more you twist them, the better.

Here, in general, and all. To some, this matter may seem very simple and understandable - for professionals, for example, it takes no more than ten minutes to assemble one bicycle. Well, if the assembly process scares you and you don’t want to spend time on it, it’s okay, you can always entrust this dreary task to specialists.

Every beginner needs a bike assembly manual, whether it's an adult or children bicycle.

Good day to all!

Hello!

This is already my second purchase of a children's tricycle. The first bike turned out to be defective, and I had to return it to the store under warranty. Therefore, when buying a bicycle for the second time, I already knew what I needed to pay attention to, what could be the disadvantages of a tricycle for children. If you are interested, then you can follow the link below and read my review on the bike, which turned out to be defective.

Comparing these two bikes, I can say for sure that the quality of the Navigator Trike is many times better, and I am 100% satisfied with this bike.

Place of purchase. This bike, like the first bike, I bought in.

Bicycle price at the time of purchase, at a discount, amounted to 6540 rubles. Price without discount 9070 rubles.

Overview of the children's tricycle

________________________________________

The bike is presented in various colors. There are six colors in total to choose from. That's why this bike presented in 6 models, each with its own article: T55927, T55928, T55930, T57566, T57567. My choice was a bike. Navigator Trike T57566, sand grey.

The bike came in branded packaging. There is a warranty card and instructions for assembling the bike.

My husband spent less than an hour assembling the bike with no problems. Every part of the bike was packed in a protective bag, also The kit included tools to assemble the bike.

Package size (H x W x D), 58 x 28 x 40 cm, weight 9 kg

The maximum allowable weight of the child is 25 kg

This tricycle is designed for children from 1 to 3 years old.

Material: metal, plastic elements, textile materials

Equipment

Parent control handle

Convenient control handle, it is possible to adjust the height of the handle in three positions. The adjustment mechanism works properly, does not stick. It is very easy and convenient to control a bicycle with a handle on the road.

The bike control cable runs along the frame, it is not hidden inside, so it is visible. He does not interfere with the child.

waterproof folding awning

The visor on the bike is just great. It is large and waterproof. The visor will protect the child both from a rain, and from the sun. It can be adjusted in three positions.

Has a viewing window, through it you can observe what the child is doing, since the visor on the bicycle interferes with the view, and the child is not visible, but through this window the child is visible.

The first position of the visor. Usually during walks we use it, the child can see everything around, nothing interferes with him.

The second position of the visor. When it starts to rain while walking, I set the visor to this position.

The third position of the visor. In this position, the visor drops almost to the protective rim. I think that it is possible to use this position only when the child is sleeping, since it interferes with my child, nothing is visible because of the visor, and therefore the baby removes it.

Soft seat pad

There is a soft pad on the seat.

For comfortable and convenient walks There are two soft cushions on the back of the seat. One is located at the level of the back, the other at the level of the head. They are sewn on, there is no way to remove them.

Besides on the plastic seat itself there is a soft insert. Usually I saw that on children's tricycles the seat is completely plastic. This seat is much more comfortable for the child.

There is a mosquito net on the sides.

Children's tricycles can be purchased not only in local stores, but also on the Internet. By the way, the second method is recommended. After all, prices online are much more affordable, and there is more choice.

On the site baby-car.ru you can find a wide range of children's tricycles with a special control handle for parents. In fact, such a bicycle can replace a stroller in the summer.

Every parent wants to surprise their child. Make it the best birthday present. Of course, at a young age, the child does not even suspect what a bicycle is.

But it can become an excellent toy and occupy his attention for a long time, unlike a stroller, where the child is doomed to simply lie down and look at the sky. The benefits of tricycles are listed below:

• the child quickly get to know the world around;
• during the journey, the attention of the child will be occupied;
• The bicycle will allow the child to develop physically.

Undoubtedly, tricycle has a handle to push it and at the same time steer it. However, do not forget that the child himself can pedal to move the bike.

In the case of buying a gift on the Internet, you will have to assemble the bike yourself, as it will come in a box, completely disassembled. Strictly speaking, assembly requires only pliers and a set of screwdrivers.

We assemble a bicycle - the basics

Each tricycle comes with assembly instructions. But we dare to assure you that the assembly for an adult is intuitive. It is recommended to start assembling the bike from the rear wheels.

Installed plastic seats under the wheels. After that, the wheels themselves are immediately mounted. Next, we proceed to the installation of the steering wheel. It is installed very simply - in the frame socket in front.

The steering wheel is fixed with a clamp. It is tightened with an ordinary hairpin - a bolt with a nut. You can immediately install a bell or a sound panel on the steering wheel (a box with buttons that, when pressed, sounds a melody).

It remains to install the handle for the parent and connect it to the steering wheel using a special rail. Some frames of children's bicycles have a removable saddle. In this case, the installation will take no more than a minute - you will need to tighten four bolts.

We put the front wheel and the bike is ready for use.

Below is a detailed video instruction for assembling a tricycle:

Despite the abundance of bikes in stores and the emergence of a popular service of bike assembly to order, self-assembly is still in demand among fans. Why is she so attractive?

Creation of a fundamentally new exclusive bike- a creative process, which consists in the selection of spare parts and checking their compliance with the desired parameters. And the assembly will allow you to accurately understand all the nodes of the bike and gain good experience in technical aspects.

Assembling a bike is a delicate and painstaking task. The difficulty lies not only in the correct installation of all constituent elements but also in the selection of all spare parts.

The main requirement for them is quality, reliability and demand. It is unlikely that with self-assembly it will come to mind to put bad brakes or some unnecessary body kit, then it’s better to go blindfolded to the store. How to plan the work, what is needed for this and how, in fact, to assemble a bicycle, will be described later.

Drawing up requirements for the bike and a plan for its assembly

Before you collect the bike yourself, you will have to decide what should happen in the end. General bike options:

• urban signalspeed;
• highway or sport bike;
• mountain bike;
• hybrids.

Based on the main types, we conclude where the bike is going to be used, what speed and running performance it should have, how comfortable it will be in riding. The last parameter is especially important, it is he who pushes the cyclist to assemble the bike with his own hands.

Where to get spare parts? They can either be purchased independently or ordered. In the first case, you will have to wander through the specialized departments for quite some time in search of every detail. The second option is simpler: pre-select a model, enter your wishes into it and place an order. Of course, it is much easier to assemble a bicycle out of the box, however, it will cost more.

Basic and mandatory structural elements for a new bike:

1. The frame is the body of the bike. It determines the purpose of the bike, its weight, dimensions and behavior on the road.
2. The fork is the attachment point of the front wheel and steering wheel to the frame. Forks can be either rigid or shock-absorbing, it all depends on the type of bike. Mountain bike equipped with a fork with a shock absorber, road and single speeds have a rigid version. The fork provides control of the bike.
3. Steering wheel. The shape determines the comfort of control, fit and maneuverability. A huge range of handlebars pleases us with a variety of options: from absolutely straight to “lambs”, with and without a stem, adjustable and non-adjustable.
4. Wheels. Their diameter affects the speed, amount of rolling, controllability. Tires, as an element of wheels, determine the dynamic performance, as well as the cross-country ability of the bike. big wheels will keep the pace better. They are sensitive to steering, but more prone to deformation. Tires, the thicker, the better they behave in off-road conditions and worse on smooth roads.
5. and a crank-pedal pair. It is difficult to overestimate the importance of the carriage assembly. It serves as an element for transmitting torque from the pedals to the drive star and then to the rear wheel. High-quality assembly of the bottom bracket and cranks is the key to a long ride in a wide variety of conditions.
6. Cassette. This node is in speed bike. It consists of a set of rear and front sprockets. A switch and is connected to it.
7. Saddle. It is fixed on, which is installed in the middle tube of the frame.
8. Brakes. An easy and common option is v-brake. Disc brakes more difficult to install, however, if the disks themselves are already installed on wheels, then the installation process is much simpler. Finally, the brake rear hub, does not require any work at all, except for connecting the wheel to the frame.

Bicycle working units (on the example of a hybrid)

Approximately in this sequence you will need to assemble the bike. In the work you will need tools: both ordinary keys and special devices.

Tools for work

The bottom bracket and cassette will require special tools, so let's talk about those first. To install the carriage, you will need a key called a puller. The knot is installed in the glass of the frame and then tightened with a wrench, then the connecting rods are mounted on the axle. For a square connection, you will need a connecting rod puller.

Attaching the bottom bracket and connecting rods to it is a rather troublesome business in terms of effort, since it is necessary to tighten it to the maximum. In the process of putting on the connecting rods, we make sure that one of them does not fly off, otherwise problems with periodic loss cannot be avoided later.

The cassette assembly is mounted on the rear wheel hub using a special cassette puller with a whip. Here you will also need maximum effort, the whip helps the stars not to turn when twisting.

Carriage (1) and cassette (2) pullers

Chain lock for link release and chain length adjustment. The squeeze allows you to disconnect the fastened chain anywhere. Chains, for the most part, do not have a special lock. If there is one, you can, in principle, do without squeeze. However, the chain may be too long, and this device is indispensable for removing extra links.

Circuit breaking device

Wrenches for attaching the saddle and wheels to the frame. The dimensions are selected according to the dimensions of the nuts. It is advisable to use ring wrenches. The adjustable adjustable version does not allow you to tighten the nut to the desired force, in addition, it can eat corners. It is best used for pre-rolling.

A torque wrench will be an excellent assistant during assembly. If the disassembled bike arrived in a complete set, assembly instructions will be attached to it. It will most likely contain the values ​​\u200b\u200bof the optimal tightening torques.

In practice, these figures allow you to achieve the strongest twisting, and during operation, metal fatigue will be minimized. Also, compliance with the prescribed tightening torques will ensure the geometric integrity of all connections.

A set of screwdrivers and hex keys. These tools will be needed when installing handlebars, saddle, brakes, and canopies such as footpegs. Wire cutters are another useful tool. They are used for smooth cutting of cables. They will also need trailers and a braid.

Sequential assembly of bicycle components

At the first stage, we have a bare frame and all spare parts aside. We start by attaching to its frame. Installation is greatly simplified if the ball bearings have been placed on the fork stem beforehand.

Installing the bearing cone and cup yourself is quite problematic, you will need special equipment - a lever press. Hammering is allowed, but this must be done with the utmost care so as not to damage the fork stem itself and the walls of the head tube of the frame.

A ready-made version with a bearing assembly is preferable, here you only need to correctly insert the fork stem into the frame. It is easier to install if the frame lies down, that is, the stem enters the pipe horizontally. The right end of the head tube corresponds to the top. Holding the pipe with one hand, insert the body of the part into it with the other.

The lower and upper cones of the fork must exactly fit on the bearing balls. After that, a special washer and mustache are put on the stem, which must enter the hole in the fork rod. Using an open-end wrench or box wrench, the lock nut is tightened to the limit. The fork is ready.

A steering part is installed on top of the fork. Correctly put the steering wheel will work with the vertical position of the frame. The only inconvenience of inserting the part into the fork is the instability of the frame, so it is better to ask someone to hold the structure in advance. First, the steering wheel is tightened at half strength, then it is centered strictly in a straight direction and then it is twisted completely. You will probably need to hold the steering wheel.

Handlebar and fork on a bicycle frame

Saddle. First, the seat itself is attached to the seatpost. The shock absorber, if planned, is attached simultaneously with the seat, and not after it. The pin is lowered into the pipe and tightened with a nut (or a ready-made eccentric). Like the handlebar, the saddle needs to be centered in a straight direction.

The next stage is the installation of the carriage in the glass. Turn the frame upside down and install the carriage assembly. The finished body is inserted and fixed in the glass with a key. If the carriage is assembled from scratch with your own hands, then we carry out the following manipulations:

• lubrication of the internal cavity of the body;
• insertion of an axial part;
• lubrication and installation of bearings;
• fixing the carriage with a puller.

After the carriage, we take a short break and install the tires on the wheel rims. First, a flipper is put on the inner surface - a protective rubber fabric from punctures of the chamber by the bases of the spokes. The flipper hole should line up with the nipple hole. A deflated chamber is carefully inserted into the rim, the nipple is threaded into the hole, and a tire is placed on top.

When installing a tire, it is necessary to follow the direction of the tread pattern. It must match the direction of the bike. Special mounts or plastic spatulas can help in installing tires. Do not forget to pump up the chambers to the desired pressure!

A cassette is put on the rear wheel hub. Its upper stars are in a free state, therefore, when inserting a node, we do not turn it over so as not to lose any asterisk. The cassette is mounted on the side of the leading front star (stars) and is tightened with force by a puller.

When working, it is necessary to hold the wheel, and also use a whip to fix the stars of the cassette. After installing it, a chain is thrown over the large star, the rear wheel is inserted into the dropouts, and the other end of the chain is pulled to the front stars. With the help of a squeeze, the chain is fastened, and the wheel is twisted on the dropouts. By analogy, we put the front wheel on the fork.

Working with carriage and cassette in pictures

The cassette is connected to the speed switch. If the bike also has a front derailleur, then, accordingly, it is connected to the chainring system. Through the cables, shifters are connected to them, which are mounted on the steering wheel. Cables with the help of clamps are neatly fixed on the frame pipes.

Assemble and install V-brakes:

• put the claws of the front and rear brakes on the steering wheel;
• attach the pads to the clamping mechanism;
• release the brakes and fasten to the fork and the rear of the frame, respectively;
• connect the claws and clamping mechanisms using cables;
• adjust the length of the cables and the position of the blocks.

Details on adjusting V-brakes:

The new assembled bike is ready for test rides. Testing is a mandatory procedure after assembly, which will show where and what needs to be fixed. Particular attention should be paid to the build quality of the fork and handlebar, bottom bracket and brakes. We also check how accurately the gears shift, whether the chain jumps off.

Assembling a bike is fun, rewarding, and, as it turns out, not too long. Done by their own hands bike will allow you to feel comfortable on trips, is fully maintainable, unpretentious and has the required running parameters.
