How to assemble the rear wheel of a kid’s bike

Installing the rear wheel

To carry out the installation correctly, assemble everything in place should be clearly in the reverse order.

  • Place the chain on the smallest sprocket, insert the wheel onto the frame mount. In this case, it is important to make sure that the axle is fully inserted into the grooves of the frame.
  • We fasten the nuts or eccentrics, they should be tightened well so that the wheel firmly sits on the frame.
  • Fasten rim brakes if fitted. Return to the previous position in exactly the opposite order, otherwise the next trip may not end very well.

After the installation process, it is advisable to check the correctness of the actions performed by means of a short test drive to see how your bike will behave on the road after the updates.

Maintenance and diagnostics of the rear wheel is a mandatory procedure to maintain the health of the mechanisms.

Replacing the bearing of the rear wheel of a bicycle will not cause you any difficulties if you understand all the nuances and features of servicing this part. The condition of the bearings, their timely maintenance and replacement is the key to safe driving.

Rear wheel hub repair. Step-by-step instruction

Most often, the repair of the rear wheel hub is necessary either with backlash or when tightening the cone. So, step by step instructions:

  • Checking the workplace. We clean the workplace of unnecessary tools, things that are not useful to you.
  • Loosen the lock nut with a wrench.
  • Loosen or tighten the flare nut.
  • Tighten the locknut into place.

If the cause of the breakdown is a malfunction or breakdown of any part, then you should simply replace it using the following recommendations:

  • After checking the workplace, remove the retaining ring.
  • Remove the hub axle. First, remove all the parts that are on the opposite side of the sprockets.
  • Checking the details for a malfunction.
  • We replace the broken part.
  • We put all the parts in place, tighten the flare nuts and locknut.

The wheel is the part of the bike that is in direct contact with the ground. And since the wheel also sometimes meets curbs, stones and other irregularities, sooner or later the rim will have to be changed. You have to go to the workshop and, having paid a rather large sum, get a well-assembled and balanced wheel. Meanwhile, you can assemble a wheel yourself, especially since hardly anyone wants to pay a third of the price of a bicycle for assembling a Kama or Salyut wheel.

So, to assemble a wheel, we need: spokes with nipples, a rim, a hub and a spoke wrench. It is also desirable to have a screwdriver, but you can do without it.

This article describes how to assemble a wheel into three crosses (each spoke intersects with three others). the most common method. Although it is possible to collect two crosses and no crosses at all (in the sun). The more crosses in the wheel, the more torsionally stiff and heavier it is. The wheel is lighter and stiffer in the sun, but it is impossible to assemble the rear wheel or use a disc brake in this case. the load on the rim and hub flange will increase dramatically.

First you need to choose a rim, hub and spokes.

It is clear that the number of spoke holes in the rim, hub and the number of spokes must match. For your first wheel, it is better to use a new hub, spokes and rim, since in this case cleanliness of the threads on the spokes is guaranteed, that is, there are no problems with screwing in the nipples, as well as with wheel balancing.

However, nowadays it is necessary to choose not only the length of the needles, but also their brand and model. If you can use inexpensive knitting needles from little-known manufacturers for riding around the house, then for extreme skiing, good spokes are even more important than good rims and bushings, although it is also better not to save on them. The best quality knitting needles are made by DT Swiss and Ritchey. The black spokes look nice, but the DT champion Yask spokes cost 75 cents for one, versus 25 cents for the silver DT champion. Whether to pay three times more for beauty is up to you. But stretched knitting needles and knitting needles with variable thickness are really better than others. The first ones are tougher than usual, the second ones are lighter, and not at the expense of strength.

Now a little about how to build a solid and beautiful wheel and how to maintain good tone (imagine, real cyclists are very sensitive to it). Aesthetically correct is a wheel, the inscriptions on the rims of which are readable from the right side of the bike, and on the hubs from the saddle. Also, some mechanics assemble the wheels so that the inscriptions on the hubs can be read through the nipple hole. There is no practical sense in all this, but if you want to comply with all the rules, then why not. On the contrary, the correct placement of the crosses is very important, especially when using inexpensive rims. The fact is that all rims have a weak point. this is the joint. It is often invisible from the outside of the rim, but from the inside it is usually easy to find.

The joint should be under two crosses that will hold it together. This article discusses just such an assembly option, in which the last rule will be observed.

Pay attention to the cleanliness of the holes for the spokes in the bushings and, if necessary, clean them so that dirt does not get on the threads of the spokes and there is no difficulty in screwing the nipples.

Lubricate the spokes thread to facilitate the assembly process.

We insert one spoke into the hole in the left flange of the hub and into the hole on the rim located to the left of the nipple (the rim is located with the left side towards the collector). We fix the spoke with a nipple (see photo 2).

We insert the next spoke through one hole in the flange and, counting three holes in the rim, insert it into the fourth.

We continue the process until you get what is shown in photo 4.

We turn the wheel with the right side towards us and insert the spoke into the hole in the rim, which is currently located to the right of the very first spoke.

Removing wheels

If possible, start by setting up your bike. It should be installed on the left side when removing the rear wheel. Do not stand the bike in an upright position without the rear wheel, as this may damage the rear derailleur.

Rear Wheels: Set the derailleur to the outer gear and the inner front wheel chain. This will loosen the chain and the wheel will be easier to remove.

Disconnect the brake rim, if equipped. The release mechanisms of typical MTB and road brakes are shown below.

Note: Disconnect pads are not required with disc brakes. Also, with hydraulic disc brakes, do not squeeze the brake lever when removing the disc from the bike. Otherwise, the pads will close and it will be very difficult for you to put the wheel back on the bike. Use a specially designed spacer such as PP-1.2 if needed.

  • Eccentric mechanism for securing the axles of the wheels: pull the lever of this mechanism outward to the end. If necessary, loosen the quick release of the adjusting nut to remove any projections on the end of the fork.
  • Straight axle: some functions are the same as the axle of the eccentric mechanism for securing the axles of the wheels. pull the lever outward to disengage and twist to loosen. Some straight axles are equipped with a special device that should weaken the axle. However, other simple levers that are needed to loosen or tighten are not used.
  • Solid axle: on wheel axles with nuts, both nuts must be loosened from the outside.

On the front wheel. just point the wheel down and out of the fork. For rear wheels, pull on the rear derailleur so the screws clear the chain. Lower the wheel by guiding it down through the brake pads and forward to clean the chain and gearshift mechanism.

Some gearshift mechanisms have a clutch mechanism that makes them difficult to turn. They have functions that make it easy to remove the wheel.

  • To engage the SRAM shift mechanism, move the lower roller forward to loosen the chain and press the button to lock it in place.
  • To engage the Shimano shift mechanism, you need to find the on / off lever and move it to the inoperative position.
  • Disc brakes

    Bicycles using disc brakes on the hub need special attention. Wheel disc brakes (Dual Pivot, Linear Pull, Cantilever, Sidepull, etc.) generally do not use significant axle pressure. Disc brake systems are fork mounted and apply a load to the rotor that is attached to the hub.

    There is an external hub axle load which tends to push the axle out of the frame pad. It is especially important to secure the pin properly in disc brake systems.

    Pre-tensioning of the spokes

    First you need to screw all the nipples to the same depth. On the rear wheel, the tension of the right spokes is made large, first they need to be wrapped 3-3.5 turns.

    assemble, rear, wheel, bike

    Next, we start stretching all the knitting needles. To do this, turn each nipple one turn. This must be done in order, starting from the valve hole. The next tightening should be done by tightening the nipples half a turn.

    Sleeve

    Self-assembly of the rear hub is required, as a rule, if you decide to carry out maintenance yourself. replacing bearings, if these are industrial bearings, replacing grease on bulk bearings, replacing a star, cleaning from dirt. In principle, it is not difficult to assemble it.

    With all the parts of the rear hub of the bike in front of you, make sure that all parts are free of dust and dirt, old grease has been removed from the bearings.

    You need to start assembling this unit by lubricating the cups in the hub and cone. Then you need to insert the bearings from the side without driven stars, if the bearings are loose, then they must be completely greased. Then we put a cone on the bearings. After that, we put in the sides and from the side where the stars are, while holding the cone on the back side. Next, carefully insert the hub axle and twist it until the axle cone snaps into place, leave a slight backlash, then put on the washer (ring) and tighten it with a lock nut.

    When to service the rear hub

    For the correct operation of the wheel and its main parts, incl. bushings, it must be kept in good condition at all times. It needs lubrication, and its body needs to be tightened periodically. In addition, replacing the bearing balls and adjusting the pads on the brake sleeve will not interfere.

    Rear hub service is essential, as in cases where this does not occur, the entire wheel may need to be repaired. Therefore, it is best to take care of your bike in the long run. It should be noted that servicing the rear hub is not much more difficult than servicing the front hub.

    It is necessary to perform maintenance in such cases:

    • If you hear body noise when the bike is moving or wobbling.
    • Backlash.
    • If the bearings crunch.
    • Poor rolling dynamics.

    If you do not pay attention to the above signs of “illness” of your bike and use it for a long time if they are present, it can quickly fail.

    Repair, in turn, will be much more expensive than simple wheel maintenance, which you can do yourself. Therefore, at the beginning of each season, check the wheel for play and that the bearings are not too tight.

    Sleeve

    The hub is located in the center of the wheels and is attached to the bike frame. Provides wheel rotation, eliminating slippage and turning. Rear hub helps roll the bike. efficient travel without wasting energy.

    Bicycle rear hub design provides the following configurations:

    • the presence of a free wheeling, lack of a braking mechanism;
    • lack of free play, the presence of a brake mechanism;
    • the presence of a free wheeling and braking mechanism.

    The dimensions of the hub, its weight and quality affect the ride and energy consumption of the cyclist while riding. There are three types of this node.

    • Ratchet Hub. Modern rear hub allows cassette sprockets to be mounted on the drum. The bearings are located closer to the middle, which negatively affects the uniformity of the load distribution. It is customary to complete teenage and inexpensive bicycle models with similar bushings.
    • The cassette hub is another modern mechanism option. In this case, the cassette is fixed by means of the slots located on the sleeve. Such bushings are reliable and can withstand loads of up to 120 kg, since the bearings in them are located closer to the edge.
    • The planetary hub of the rear wheel of a bicycle is a design that combines the functions of a hub and a derailleur. The device of the rear wheel hub of this type of bicycle is rather complicated: the mechanism is closed by a case, which protects it from dust and moisture. At the same time, when working with it, the chain will last longer, since it does not change the position for switching speed.

    The 3-speed hub has a simple design, while the 5- or 7-speed gears are best left unassembled. Gears of planetary systems are installed in a certain position during assembly. Such work requires special equipment.

    There are three types of defects.

    EIGHT. when the wheel rotates, it moves so that the rim is not in the same plane constantly.

    EGG. wheel beating up and down when rotating.

    UMBRELLA. constant displacement of the wheel to the right or left relative to the hub.

    All of the above defects are corrected by loosening the knitting needles from the side of the bend and pulling up from the opposite. It is important to remember that when the tension of one spoke changes, the tension of the others changes, and all the needles are involved in correcting one or another defect. To gradually reduce the defect “to naught”, you need a wheel straightening machine. You can use a bicycle instead of a machine. If your bike has V-break rim brake mounts, it couldn’t be easier. Removing the brake,

    We put on a clothespin on one of the pins (photo 14,15)

    And, moving it to the edge of the rim, we rotate the wheel. Having found the place of the defect in this way and having adjusted the tension of the spokes as needed, we repeat the operation. Thus, you can straighten a figure eight or an egg. The umbrella can be easily straightened by eye.

    So, you can put the wheel on the bike and go. Just do not forget to inspect the wheel afterwards and correct new defects if they appear. And henceforth, be careful and monitor the pressure in the chambers. it is better to pump a little than to correct the wheel or assemble it again.
