Flat tire

Probably the most common thing to fix: a flat tire. The videos will guide you step by step how to (1) take off the wheel, (2) take out and replace the inner tube, and (3) fix the inner tube.

Front derailleur

These two videos are about the front derailleur, the part that shifts your front gears. City bikes might not always have these, but especially old mountain bikes and road bikes usually are equipped with front derailleurs. Watch the first video to understand how it works. If you need to adjust it, watch the second video.

Rear Derailleur

Here are two videos about rear derailleurs, the parts that shift your rear gears. The first video shows how a rear derailleur works. The second video shows how to adjust a derailleur so it shifts correctly. This can be a solution when the chain does not shift all the gears, when it skips gears, or when when it makes a rattling sound while biking.


Some bikes have so-called internal gear hubs. The gears are shifted with a mechanism that is intergrated in the wheel hub instead of an external derailleur mechanism. If you have such a hub shift system from Shimano and need to fix it, watch the below video. Unfortunately, these can be very tricky to adjust and we couldn’t find a video to explain all the details. If in doubt, ask a Köksmästare when something is still unclear. The first video is for a 3 speed, the second video for a 7 speed shifting mechanism.


Your break cable needs to be replaced? Watch here to learn how do that.

Brakes need adjustment when the wheel does not turn smoothly, when the brake power is insufficient, and\or when you replace the brake pads. The video includes instructions for various break systems, click on your system at 10-second video mark. Remember that brakes will be difficult to adjust perfectlz when the wheel is not straight. We have a section on how to true a wheel below.

Wheel trueing

Is your wheel wobbly? Here we have a video that explains how spokes work together and how to make your wheel straight (true) again. We have spoke wrenches at Cyckelköket. Ask one of the Köksmästare for help. We also have a truing stand.

Determine cassette/freewheel and removal

A video to determine if you have a freewheel or casset rear cog and how to take them off. You want to do this when the rear cogs are worn out or the teeth are damaged. This can cause the chain to skip while you are biking even though your rear derailleur is set up correctly.


A video about how to replace and size your chain. We sell different chains at Cykelköket. The size of your chain depends on how many cogs you have in the back. There are single speed chains for if you have a rear-wheel with one cog and there are chains for a 6, 7 or 8-speed cog. Ask your Köksmästare for help if in doubt.


A video about how to determine which crank system you have. The crank is the metal arm that attaches to the pedals where you put your feet on one side, and it attaches to the bottom bracket on the other side. There are various systems, this video guides you to the system you have and then has specific sections about how to remove them.

Bottom brackets

A video about bottom brackets, the part to which the pedal cranks attach. It is mounted in the bottom of the bicycle frame. Bottom brackets need replacement when the pedal arms wobble, when they make weird sounds, or when the pedals do not turn smoothly. At Biltema they have new ones which would fit most situations. This video determines which bottom bracket system you have and then you can continue with the right video about your specific bottom bracket. At Cyckelköket we have the most common tools to maintain bottom brackets.

Handle bars and grips

If you want to replace your handlebars and grips, check out these videos.


Two videos about the handlebar stem, the part where the handlebar attaches to. There are two systems: (1) threadless (more common on newer mountain and road bikes) or (2) quill stems (often used on city bikes and older mountain / road bikes).
