Bicycle seat bag: design features
This model is made of jeans and is attached under the saddle of a bicycle. Sewing is easy for those familiar with a needle, thread and sewing machine
If there is no desire or opportunity to buy new fabric and other materials, old jeans and an outdated children’s backpack are suitable for manufacturing.
- lining material;
- mesh for s;
- fastener. zipper;
- straps (slings).
Round Leather Bicycle Bag DIY
You need to start work by creating a sketch of the blanks on paper and transferring the dimensions to the pattern. The dimensions of the box are selected according to the seat space of the bike, where the accessory is attached.
How to make patterns of blanks
The bike bag consists of four types of parts:
- Main part. 2 pcs;
- Side strip. 1 piece;
- Zippered flap that closes the bag. 1 piece;
- Flap s made of mesh fabric. 2pcs.
We draw their sketches by size on paper, cut out and transfer to fabric.
How to sew a bag in 10 steps
For every detail, except for the s, we will cut out an additional lining made of waterproof fabric.
Stitch the lining to the jeans along the contour.
Sew a plastic edging to the two main parts (1) along the rounded contour line. It will help keep the shape and protect the seams from wear.
Butt seams, if present, are treated with denim tape.
On the upper part of the side strip (2), closer to the closing cover, we sew a strap (sling) for attaching to the bike saddle. It extends through the saddle frame and wraps around the entire piece. Sew on a plastic buckle for fastening with a belt.
Place the second strap with a buckle on the bottom. It hooks onto the bike frame so that the finished product does not wobble when riding on the road.
Now we sew one main part (1) to the side strip (2), folding them with the front sides inward. The plastic edging should also be inside.
On the other hand, we attach the second main part (1) symmetrically. We turn the finished product there. It turned out to be a neat bag with a rigid frame.
We trim the upper edge of the mesh s (4) with decorative tape or bias tape. You can take ready-made stitched s from an old children’s backpack, then processing is not required.
We sew two mesh s (4) to the valve (3):
Insert a plastic edging around the perimeter of the valve. We sew the cover-valve to the finished bag in its lower part along a straight cut.
Along the free rounded edge we insert a zipper with two locks, so that the bag can be easily unzipped with either hand.
We fasten the finished bike bag with slings to the bike, and go on a journey.
The bike seat bag fits well on modern bikes without fenders or trunks. Its size can be increased if desired.
Bicycle pants on the trunk: how to make it yourself. cutting and assembly technology
We are considering the fourth design of the bike bag, which can be made with the largest dimensions and can be securely fastened with straps on the trunk.
How to make a quick-release mount: the secrets of technology
An important and unique part of this model is the bike carrier, which attaches the bag to the bicycle handlebars, allowing it to be quickly hung up and easily removed.
- an aluminum plate with a fixing groove, rigidly screwed to the bag;
plastic mount with aluminum plate on the bicycle handlebars.
The handlebar mount is machined from a thick sheet of polyamide plate using the example below. Choose the dimensions for the design of your steering wheel.
You can grind polyamide on a grinder. Separate operations are done with a hacksaw and a file. Drill holes for mounting screws.
A rectangular aluminum plate with a hole for a spring-loaded ball in the middle is screwed to the front side of the mount. The ball serves as an ordinary latch-retainer. The dimensions of the rectangle correspond to the dimensions of the fastening part of the bag.
The mount, mounted on the bag, consists of two plates, located on the outside and inside, and fastened with screws.
The outer part of the mount is made of two plates welded with argon welding. U-shaped grooves are made on the upper part for easy fitting on an aluminum rectangle with a spring-loaded ball.
The bottom plate has fastening ears with holes for screws and a recess into which a spring-loaded ball falls when snapped
These parts are cut with a file. Both plates are welded together by argon welding.
The mount is screwed to the inner plate on the back wall of the box with four screws, although it is more rational to use the old old rivets.

What Honor should have for nesting patterns
On paper, draw a right-angled triangle with legs equal to B and D.
We calculate the perimeter of the resulting triangle P, this will be the length of the side of the product 402849 = 117 cm.
We draw a pattern for it: a rectangular strip with a length P. In our case, P = 117cm, and set the width for it to 10 cm.
- Rounded rectangular triangle. 2 parts;
- Lateral surface in the form of a long rectangle. 1 part;
- Rectangle 157 cm. 1 piece;
- Rectangle 1013 cm.1 piece;
Rectangles will cover the beginning and end of the zipper.
On the lining fabric we transfer a side in the shape of a triangle with a size slightly smaller than the main one. 2 parts.
According to the drawn dimensions with scissors, we cut out blanks from the main and lining material.

List of consumables
Consumables are constantly needed in the operation of any vehicle, even a completely new one. a car, motorcycle, scooter, bicycle. These are elements that quickly become clogged or become unusable and must be regularly changed in the process of using the equipment. These are, first of all, greases, synthetic-based liquid oils, solvents, and some other materials.
- Thinner for complex cleaning of the drive chain and sprockets.
- Grease for handling fork springs, shifters, suspension O-rings, ratchets, bearings.
- Cleaner of brake elements and transmission parts.
- DOT bicycle brake fluid or hydraulic oil. Fluids are tailored to the specific brakes on your bike.
- Oil for lubrication of springs of gear switches, chains, contact pedals, in dirty operating conditions.
- Oil for lubricating fork pants, impregnating oil seals, lubricating air suspension chambers.
- Fork oil. Attention: be sure to fork! It is necessary for damping.
Bicycle repair and maintenance consumables
Shock absorbers and forks are used to minimize shock loads. Thus, the cyclist feels comfortable when overcoming road irregularities. The elastic components of the suspension are compression springs or air chambers. Vibration damping units are open oil baths or closed-type cartridges.
The springs gradually lose their elasticity. They sag more and more. Special rings seal the air chambers, but during operation they also wear out and allow air to pass through, which is necessary to create comfort when driving. The products of wear of metal surfaces are concentrated in the oil, so it gradually loses its damping characteristics.
Oil seals, o-rings located in the fork begin to leak. They allow air to pass through, and dirty footprints remain on the cyclist’s feet. If the anthers, oil seals, O-rings are not replaced in a timely manner, play will appear in the guide bushings of the fork. bosses. The diameter of the fork legs varies between 28-40 mm.
Most often, for popular models, this section is 32 millimeters. The Demo 8 and Fox 2008 World Cup Edition have this size of 40 mm. The larger the cross-section of the fork legs, the more reliable the entire front end structure. This means that the torsional stiffness is significantly higher. By changing the texture and color of the fork, the owner can easily determine the wear of the suspension. For this, manufacturers use a special spraying of the rubbing surfaces of the legs.
Different models of forks are operated with different spraying. Technologies used:
- chrome plating;
Complete wear on the bolsters becomes the main cause of wear on the fork legs. The bushings direct your feet straight into the interior of the fork. This prevents backlash in the pants.
Falling wheel stiffness
The wheels are the most loaded part of the bike. The new discs are perfect, without beating, but after several years of operation, the profile of each rim has a lot of deformations. dents, eights, stretched spokes. Some improvement can be achieved by tightening the spokes with a special wrench.

DIY bike repair tools
Complete bike bulkhead
This section of our article offers to get acquainted with the basics of cardinal dismantling and mounting of a bicycle. Similar to wear issues, all systems on a road vehicle will be considered.
Before starting dismantling, the frame should be completely cleaned of corrosion, dirt, sand, small stones. If you ignore this, you will not be able to avoid problems in the future. Residual dirt along with the oil will get into the working parts and will threaten the performance of the bike as an abrasive. As long as there is dirt on it, it is difficult to understand the working volume of the entire repair. Washing is best done under light pressure. A good option is a damp cloth and brush.
Having cleaned the frame 100%, you should make a careful inspection of each unit, making sure that there is no damage or wear or damage. The characteristic problem points of each frame are:
- rear suspension hinges;
- the upper feathers of the rear triangle;
- head tube;
- carriage tube.
If even the smallest defects in the weld seams are found, the entire frame will have to be definitely replaced. It is recommended to paint over frayed frames. For white or black, this procedure is not difficult. The rest of the colors are selected by computer specialists. For touch-up, you need a can of paint and masking tape. In order for the dye to perfectly fit on the metal, you must use an alcohol solution.
Drop in frame stiffness
Excessive build-up of fatigue stress distorts the frame geometry. The deformed load-bearing body is not able to correctly perceive the load modes from all road irregularities. The risk of cracks, breaks at the connection points of frame pipes increases.
Cracks most often occur at the weld seams on the head and bottom bracket shells. It also happens on the feathers, dropouts. the places where the rear and front wheel hubs are seated. Careful, unhurried driving will help prevent fatigue stress build-up too quickly.
DIY repair tools
High-quality service of bicycles, especially expensive exclusive models, requires the use of good reliable tools, materials, devices. Below is a basic set recommended by cycling experts. It is desirable for every cyclist. It is simply impossible to replace this list with any analogs.

DIY bike tuning. 3 easy steps
Tuning comes from the world of cars and means the improvement of transport. The goal can be different. to increase ride comfort, improve technical parameters or appearance. But if it is problematic to upgrade the “iron horse” without the help of professionals and special equipment, modifying a bicycle with your own hands is a feasible task for a cyclist. How to do this. in the article.
The easiest way to update the led and give it personality is to paint. Even an old “Stork” can transform a fresh color, let alone the fashionable Leon XC 80.
- paint of the desired color in cylinders.
First, you need to scrupulously wash the frame by twisting the rest of the parts from it. After. remove the old paint using a solvent. Irregularities and roughness should be sanded with sandpaper, and then the surface for painting should be degreased and allowed to dry completely.
As before painting the walls, the frame needs to be primed. Better. in 2-3 layers, while each previous layer must dry before applying the next. And only after the last layer has dried, paint is sprayed onto the surface. The manufacturer usually indicates the drying time on the cylinders.
Important: You should take care of good ventilation in the room where the staining is carried out.
Additionally, you can decorate the frame on a model like the Cross 1300 with your favorite designs. This will require special stencils, which can be purchased at specialized retail outlets or made yourself on self-adhesive film.
Wheels are painted in the same way as frames. But it is imperative to close the sleeve and knitting needles from the paint. Also available for DIY styling:
- change of tires;
- hauling wheels with a film;
- equipping them with blades made of plastic or plywood.
Those looking for a big change should look out for cast wheels with a robust and eye-catching design.
light on the bike. so every ride is different
Light tuning has been popular in big cities for many years. And for good reason. the backlight led not only looks spectacular in the dark, but also protects the rider on the road. Of course, it is not at all necessary to turn the bike into a Christmas tree, like the aliens in the film “Men in Black”. But some elements really come in handy and help you stand out.
Flashlights and headlights
The headlights of bikes such as the MAGNUM M come in a variety of designs and designs. They are also distinguished by the method of installation and type of lighting.
The basic types of bicycle headlights are front and rear. The fact that a vehicle should be equipped with them has practically become the norm. After all, this is the main lighting that makes the cyclist visible on the road.
Headlights are used to illuminate the path and indicate their presence at night. Not all types of flashlights are suitable for this: LED lights do well, which are affordable at the same time, and xenon. these will cost more.
The taillights will provide safety at night or in bad weather. they will help the cyclist to be identified by those who are riding behind. Such lights should work in two modes. flashing and constant. As a rule, LED lights are used for these tasks.
A new “feature” in the light tuning is the turning headlights. Their use to indicate maneuvers is more comfortable and safer for the cyclist and other road users.
LEDs and neon will help make a bike like ONTARIO SPORT brighter and more attractive. The LED strip is a flexible strip on which the LEDs are located at an equal distance. It is sold in bobbins, and it is easy to divide it into the desired lengths. The long ones are suitable for frame upgrades, and the short ones can be installed on wheel rims or spokes.
Neon tubes will appeal to those who prefer soft, slightly diffused light. Such illumination looks aesthetically pleasing, but you cannot see it from afar. In addition, tubes are easily damaged and require more LEDs to operate.
The use of reflective elements is necessary, first of all, for the safety of the biker himself and other vehicles. So, both pedestrians and cyclists are advised to wear clothes with stripes or prints that reflect the light of car headlights in the dark.
To become more visible on the road, the “biker” will not interfere with reflective stickers on the bike. You can stick them on the frame, rim or fork. In addition to safety, this design looks stylish and discreet in the daytime.
Phosphor stripes will help to highlight the great for beauty or to make the spotlight of the controls. You can choose a contrasting color with the main color, or vice versa. in tone.
Additional accessories. we make the bike even more convenient and practical
To make a model like the Discovery Canyon as comfortable as possible in everyday use, you can gradually add the necessary accessories to it. Details like these will also make your rides safer and give your bike a special charm:
Fenders will protect the rider from dirt on the road or in bad weather. If you drove without them, you can put new ones. As an option. replacing “relatives” with more suitable design and materials.
The rearview mirror is no longer the prerogative of motorists. On the track, this accessory will help monitor the situation and correct maneuvers in time.
Those who prefer to move on the sidewalks need to get a horn or bell. This is much more impressive than shouting “step aside!”.
Only those who try to gently lean the bike against benches, walls and fences several times every day will truly appreciate the value of the peg.
A trunk or a retro basket is not only useful in the household. These accessories create a complete and holistic image of the bike and its owner.
For long-distance travelers without water, no way. Yes, and in the hot summer you will not go far without her. Therefore, a bottle or bicycle flask holder is a priority purchase.
Experienced bikers will need a bike computer. The gadget will help you get and analyze the most useful information about the distance traveled and physical activity.
Of course, for those who take a bike out of the attic a couple of times a year, tuning it is an unimportant task. But cyclists who can no longer imagine life without riding their favorite bike will enjoy the do-it-yourself upgrade. After all, you can arrange the lead exactly as you want, and not explain the reasons for your choice to anyone. Therefore, it is worth doing improvement at least in order to create something special, unique, reflecting an attitude to life.
