The main components of the wheel
A standard bicycle wheel consists of several main parts:
- bushing. the central part, due to which the torque is provided. The interior of the rear hub is slightly more complex than the front. Not every bushing can be disassembled at home, some variations without special equipment and knowledge are better left untouched. And also brakes can be attached to this part;
- spokes connecting the hub to the rim;
- the rim on which the tire is mounted;
So, if the rear wheel of a bicycle needs to be repaired, or if it’s just time to service the spare parts, it is necessary to clarify the procedure that should be taken when removing the wheel.
When to remove the rear wheel
It is unlikely that the idea of unscrewing the chassis from the bicycle frame would just come to mind, unless, of course, a person specializes in bicycle dismantling. But this is a completely different case. Dismantling the rear wheel will be required if the following problems are observed:

- noticeable damage to the rim;
- complete wear when a wheel needs to be replaced;
- a flat tire or a burst tire;
- bulkhead bushing.
This includes the planned replacement of the rear sprocket system and chain.
Before removing the bike, turn it over and place it on the saddle and handlebars. It is better to remove awnings in the form of a mirror, a bell and a lantern in advance so as not to damage them under the weight of the frame. V-brakes are first released and disassembled, otherwise they will not allow the wheel to be pulled out freely. With disc models, everything is easier. you can immediately remove the wheel.
I must say that the removal process itself consists only in unscrewing the eccentric or unscrewing the fastening nuts from the axis of the bushing, who has something. If the mount is an eccentric, simply unscrew the handles and twist the wheel. The nut fastening is loosened with one or two wrenches.
Usually one wrench of the appropriate size is enough, with which the nuts are removed one by one. If the hub axle turns, then the nuts are unscrewed simultaneously in different directions. It is recommended to use open-end wrenches or box wrenches. The adjustable version is undesirable, as its thick horns “eat up” the corners of the nut due to loose fit and sliding.
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.

How to remove the rear wheel?
The rear wheel removal process is COMPLETELY the same as the front wheel removal process. You don’t even need to look at the equipment attached to the rear (you only have to remove the chain from the axle if it gets caught).
The wheels must be properly fitted to the bike frame. Misalignment can lead to problems with shifting and adjusting the bike. If the wheel is not securely fixed, it can fall off during the ride and injure the cyclist.
City Bikes- Installing Your Front Wheel
Rigid axle bushings use axle nuts on the outside of the frame plate. The axle nut contains a washer built into the axle nut, or a separate washer. If the washer has teeth or knurls, then they are connected to the recess to secure the wheel. Lubricate the threads on the axle when the wheel is mounted on the bike.
It is often easier to mount the front wheel when the bike is on the ground. When placing the bike on the ground, the axle must be completely in the pad on the frame.
Make sure that the cam lever for locking the axles of the wheels is in the open position and that its brakes are open.
Place the wheel in the pad on the frame. Make sure the hub is fully seated in the frame or fork.
- On the rear wheel, first turn the gear back and place the smallest gear between the top and bottom of the chain. Place the wheel between the brake pads, hooking the smallest gear on the chain.
- Cam mechanism for securing the axles of the wheels: tighten the axle so that the lever meets resistance 90 ° from the frame or fork.
- Straight axle: move the axle in place and turn clockwise until it stops.
- Solid axle: tighten both nuts on the axle until they stop.
- The use of a torque wrench is recommended. However, if it is not available, an effort must be made. For 25 Nm, apply about 40 pounds of pressure to the end of a 5 “wrench.
Determine the end position of the lever closing. Rotate the front arm and adjusting nut so that the arm ends up just at the front of the fork. Place the rear arm between the chain support and the seat. Reposition the lever as needed if it is not fully closed.
Re-remove the brake mechanism if applicable.
Make sure the wheel is in the center of the frame or fork. Loosen the nuts on the axle and, if necessary, adjust the center of the wheel in the frame and retighten.
Make sure the brake pad rim is centered on the wheel and adjust as needed.
Disassembly and assembly of the rear bicycle wheel
It’s no secret that any vehicle periodically needs repair and maintenance. The bike is no exception. And also sometimes this need is due to the desire to upgrade your bike. To prepare it for such manipulations, of course, the structure will have to be disassembled, and although a bicycle is not a very complex mechanism, still not every cyclist has an idea of how to disassemble the rear wheel of a bicycle.
DEVICE AND INSTALLATION OF THE FRONT WHEEL ON THE BIKE
The front wheel of a bicycle is a driving unit, without which it is impossible to imagine a bike, perhaps a unicycle. The driven wheel, synchronized with the fork, is responsible for the trajectory of the bike and, to a greater extent, the rolling speed. Unlike the rear wheel, the front wheel is simpler in design, but also requires timely maintenance.
A bike, like a car, needs regular maintenance, and the front wheel is one such important component that should not be neglected. Let’s give him a little attention!
Removing the front wheel from the fork
Removing a wheel is the simplest maintenance procedure for your bike. This is done very simply:
- Turn the bike upside down.
- Release the rim brake, remove the caliper from the disc.
- Loosen the fasteners from the fork dropouts.
- Remove the wheel axle from the mountings.
How To: Remove and Install Bike Wheels
On dropouts, the mount is nut and eccentric. In the first case, you will need two 15 mm wrenches. we hold the nut with one, and gently twist the other on the opposite side. With the eccentric, everything is easier. loosen the retaining nut and fold the clamping lever.
Removing and installing the front bicycle wheel
Every bicycle owner sooner or later faces the issue of partial or complete disassembly of his vehicle. Whether it is minor repairs, replacement of parts, diagnostics or just transportation, there is often a need to remove one or both wheels at once. It is best to gain the skills to do it yourself, without resorting to the services of repair shops, since it is not always possible to contact a specialist, and such a need may appear suddenly on the road. Of course, in the absence of skills, for a new cyclist, dismantling and mounting a wheel may seem like a difficult procedure, especially if the bike is equipped with additional devices, but learning how to carry it out on your own does not take much time and does not require the experience of a bicycle mechanic.
During transportation, the front wheel of the bicycle is usually removed, although sometimes it becomes necessary to remove the rear wheel as well, this already depends on the requirements of the transport company, which may limit the dimensions of the luggage to one degree or another.
Regardless of the reason for the removal of the bicycle wheel, the principle of the manipulations performed will be the same.
Before removing the front wheel from the bike, it is necessary to get rid of the bike itself of all accessories and additional devices, so as not to damage them under the weight of the structure during the dismantling process.
- We turn the bike upside down, put it on a stand for repair. Or, in the absence of a special rack, simply on a handlebar with a saddle.
- Now you need to decide on the type of brake system installed on the bike.
- Disc brakes won’t be a hassle when removing a wheel. The only thing to consider is that hydraulic brakes do not like the inverted position, because air can enter the system. In this case, the brakes will have to be pumped after all the procedures performed with your bike.
- The rim brakes will need to be unfastened before removing the structure from the mounts. To do this, squeeze the levers with your hands and remove the end of the cable from the clamp, then spread the levers to the sides.
- The hub axle is attached to the fork by means of an eccentric or nuts. In the first case, you just need to unscrew the eccentric, unscrew and remove the wheel from the ends of the fork, gently pulling it up. In the second, unscrew the nut with a wrench; for convenience, during unscrewing, you can hold it with a second wrench.
After the wheel is removed, you can continue to carry out the necessary work with it, for which it, in fact, was removed.
What does the wheel consist of?
Bicycle wheels are the most conservative component. Of course, there are models on cast disks, all-round wheels are put on track models, but they are in the minority. Still, the majority of bicycles are equipped with spoke wheels.
- ordinary sleeve;
- connecting knitting needles;
- rim protective tape (flipper);
- camera and tire;
- disc (on models with disc brakes).
The hub is the axial part of the wheel, it is an assembly of the central axle, bearings and tapered retainers. Cone bearing systems are most often mounted on bushings with open type bearings. They can also be equipped with sealed bearings or slips.
Rim. supporting structure, metal ring. The rims are made mostly of aluminum, with carbon rims being used on expensive models. In terms of rigidity and power, they are divided into three types:
- single-walled. the outer and inner surfaces have one line of contact (jumper);
- double. the inner surface is attached to the sidewalls, separated from the outer;
- triple. the strongest and most durable option: the inner wall is also fixed to the sidewalls, but, unlike the double rim, the triple rim has an additional wall in the middle.
Vertical bridges form channels running in the direction of rotation. According to the number of such channels, modern rims are divided into one, three- and five-piece:
Spokes. elements connecting the hub to the rim. They perform the functions of securing, distributing loads along the rim and central axis and mitigating vibrations during movement. The rim is perforated, each hole is designed to hold one spoke. The number of spokes is set on a bicycle wheel in multiples of four. Depending on the model, their number varies. from 28 to 40 on average.
The number of spokes for the front wheel is usually less than the number for the rear. This is due to the fact that the bulk of the load falls on the rear of the bike, and there the wheel must be stronger.
- standard (rolled). constant circular cross-section along the entire length from the bushing attachment to the tip;
- aerodynamic (blade-like). elliptical or rectangular profile;
- variable cross-section (pulled). standard cross-section at the heads and tapering towards the middle.
The inner tube is the inside of the tire that holds the pressurized air inside. Tire. the outer shell, in contact with the road, absorbs bumps, protects the camera. The tire is made of a harder rubber than the tube.
Rim tape, or flipper, is a rubber lining under the tube to protect it from puncture on the spoke tips. Dynamic loads force the walls of the chamber to bend, which causes them to be pressed against the rim surface. Without a flipper, the camera can be pushed into the hole with the spoke tip. This problem is more pronounced on the rear wheel, where the loads are higher, but the presence of a flipper is mandatory on the front. The torn tape must be replaced with a new one. A proven homemade option. glue the rim with several layers of electrical tape, except for the hole for the nipple.

How to remove / install the front wheel from a bike
Removing / installing the front wheel on a bicycle is one of the simplest tasks a cyclist may need. Usually, the front wheel is removed for transport or storage of the bike, but there are also situations when you need to remove the wheel in order to glue the camera or change the tire.
How to remove the front wheel?
If you have disc brakes, the task is even easier, but remember to insert a spacer between the brake pads because during transportation or repairs, you may accidentally press the brake, the pads will compress and complicate the installation procedure, especially if the brakes are hydraulic.
In order to remove a wheel from a bicycle with rim brakes, you need to unfasten the pads or lower the front wheel.
To unfasten, disconnect the pads, you need to press them to the rim with your hands at the junction of the cable, and pull the arc so that it crawls out of the groove.
Unscrew, remove the wheel.
After you have dealt with the brakes, proceed to removal. The wheel can be attached to the fork in two ways:
1) With a bolt. then you need an open-end wrench or box wrench of the desired size (usually from 13 to 17 sizes, but most often 14 or 15 sizes). Bolted connection is now found on children, teenagers, and also cheap bicycles.
2) Quick release. eccentric connection. Most common these days. Removal / installation of the wheel becomes possible even without the use of special tools. In order to remove the wheel, simply move the position of the eccentric clamp to the opposite side and holding it with your hand, make a couple of turns of the “wing” until you feel that the wheel moves easily.
The installation process is the opposite of removing.
1) Be sure to check the direction of the rubber when installing (compare with the rear wheel).
2) Do not pinch the eccentric when you press the eccentric handle, it should lower without much effort, but also check that the wheel does not wobble.
3) Check the center of the wheel, rotate it several times and apply the front brake, the wheel should not rub against the pads.
