Learning to repair your own bike: self-service workshops and repair stations – guide

Editorial team·updated on 25 Sep 2026

The workshops, hire offers, pumps, parking and routes in this guide come live from our records. They are not written into the text and are not maintained twice.

Five skills cover eighty per cent of everything: what a Berlin self-service workshop is, which tools you actually need, and where the line to a professional workshop runs.

The situation

Your bike has been standing in the courtyard for three weeks because the brake is rubbing and the chain skips every third pedal stroke. A workshop told you on the phone: two weeks' wait, and we will talk about the price once we have seen it. You have a set of Allen keys in a kitchen drawer and a suspicion that neither problem is actually a big deal.

That suspicion is correct. Five skills cover roughly eighty per cent of all bicycle problems, and none of them takes more than half an hour or tools costing more than eighty euros. What is missing is not talent, but someone standing next to you the first time saying: no, the other way round.

That is exactly what Berlin's self-service workshops are for – at least one in every one of the twelve districts. This guide explains what to expect there, which five skills are worth learning, and where the line runs at which even the best guidance stops.

What a self-service workshop is – and what it is not

What it is: a place with repair stands, tools and spare parts where you work on your own bike. These places are run by associations, neighbourhood initiatives, youth centres, universities and community centres. Some are called repair cafés, some neighbourhood bike workshops, some simply bike workshops.

What it is not: a cheap workshop. Nobody takes your bike off you and hands it back repaired. If you want a finished repair without doing the work yourself, a commercial workshop is the right place – and there is no shame in that, it is a decision about your time.

The difference that matters. These places differ on one point more than on any other: whether there is guidance or only free use.

For your first visit you want guidance. That is why it is the filter the list further down uses.

The third option: public repair stations. Fixed stations with tethered tools are dotted around the city – Allen keys, screwdrivers, tyre levers, often a pump. They are accessible around the clock and cost nothing. For a quick correction on the road they are excellent. For learning they are of limited use: no repair stand, no spare parts, nobody watching. And the official inventory is thin and unevenly distributed – in Lichtenberg it currently lists no usable station at all.

Step by step

1. Look for a workshop with guidance, not the nearest one

The nearest workshop is not much use if it only offers free use and you do not know which way round a brake pad goes. Filter for guidance first, then for distance. Twenty minutes' travel to the right place beats five minutes to the wrong one.

Check on the record: opening hours (most have fixed, often weekly sessions rather than continuous opening), whether spare parts are sold, and whether there is a repair stand. Without a stand you work on the floor, and for brakes and gears that makes an enormous difference.

2. Go with one single concrete question

The most common mistake on a first visit is wanting to "go through everything". The result is that two hours pass and nothing is finished.

Better: one goal. "I want to change the rear brake pads." "I want to learn to change a tube." "My chain skips and I want to know why." With a goal you go home after two hours with a working bike and one skill learnt. Without a goal you go home with a dismantled bike.

Bring the bike roughly cleaned. Nobody enjoys working on a drivetrain caked in grime – including you.

3. Skills 1 and 2: changing a tube and inflating it properly

The place to start, because it is the most common breakdown and because you cannot break anything. Take the wheel out, lever one side of the tyre off, swap the tube, refit the tyre – and make sure nothing is pinched.

The underrated second half is tyre pressure. Every tyre sidewall carries a range, for example "4.0–6.0 bar". With a floor pump and a gauge you hit it; with a mini pump and your thumb you do not. Too little pressure is the most common cause of pinch punctures and of the feeling that the bike runs heavily. This is the single best effort-to-effect skill on the list.

Check the pressure every two to four weeks. Even intact tubes lose air.

4. Skill 3: cleaning, oiling and measuring the chain

Clean, dry, oil thinly, wipe off the excess. It takes ten minutes and extends the life of the entire drivetrain.

The real learning, though, sits in the chain wear gauge, a strip of metal costing a few euros. You lay it into the chain: if it drops in, the chain is stretched. This matters because a stretched chain wears out the sprockets and chainrings along with it. Replaced in time, a chain is cheap; replaced too late, it takes the cassette and chainring with it and the bill multiplies.

If your chain "skips every third pedal stroke", the gauge is the first thing to reach for.

5. Skill 4: checking and changing brake pads

On rim brakes you can see the grooves in the pad – once they are gone, the pad is gone. On disc brakes you look at pad thickness; once there is barely any pad material left on the backing plate, that is the end.

The swap itself is easy. The work is in the alignment: rim pads must not rub on the tyre and must not slip under the braking surface, and disc callipers must sit centred over the rotor.

The point at which you want someone standing next to you: after any work on a brake, the effect gets tested – first standing still with a full-strength squeeze, then at walking pace in the yard, and only then in traffic. A brake that does not bite cleanly is the one mistake on this list that genuinely hurts.

6. Skill 5: adjusting the gears

Ninety per cent of all "my gears are playing up" cases are slackened cable tension, and that is what the barrel adjuster on the derailleur or the shifter is for.

How to do it: bike in the stand, shift into the gear where it hesitates, and turn the barrel in small steps – half a turn at a time, then try it. If the chain climbs onto a larger sprocket too slowly, you need more tension; if it jumps too eagerly or rattles, less.

What does not belong here: the limit screws that set how far the derailleur travels. Turning those without guidance sends the chain into the spokes. Leave them alone the first time.

7. Know the limit – and stick to it

Five things belong in a commercial workshop, without exception and regardless of your own ability:

• Fork, frame, handlebars, stem – everything that breaks rather than wears out.
• Hydraulic brake systems – bleeding and shortening lines need tools, fluid and experience.
• E-bike drive, battery, wiring, diagnostics. An opened battery is a fire risk, and interfering can void the warranty.
• Wheel building and truing. Lacing a wheel is a craft of its own.
• Bottom brackets and headsets – both need specialist tools that are not worth owning privately.

This is not capitulation. It is the difference between someone who has their bike in hand and someone who at some point no longer does.

8. After two or three visits, build your own basic kit

Do not buy a tool set in advance. After two or three visits you will know exactly what you touch and what you never touch. The honest basic kit for the five skills: Allen keys 2 to 8 mm, Phillips and flat-blade screwdrivers, two tyre levers, a floor pump with a gauge, a chain wear gauge, chain oil, rags. Together that comes to €30 to €80 (as of 09/2026), and the floor pump is the best single investment in it.

Everything beyond that – repair stands, truing stands, pullers – is precisely what the self-service workshop exists for. You do not need to own it.

Time and cost

Time. The first visit takes two to three hours, of which the first half hour goes on arriving, finding a stand and finding tools. A guided tube change: thirty minutes. Brake pads front and rear: an hour. Adjusting the gears: twenty minutes once you know which screw. Chain care: ten minutes, repeated every few weeks.

Do not plan your first visit for a day on which you urgently need the bike afterwards.

Cost. Use is free or donation-based at most places; some ask for a small hourly contribution or a membership. What you pay for in every case is consumables and spare parts – tubes, pads, chains, cables. Many workshops sell used parts far more cheaply than new ones; for an everyday bike that is often the most sensible choice.

Terms differ considerably from place to place. They are held on each individual record rather than in this text – that is where they are maintained.

The real return is not a saving per repair, but the abolition of the two-week wait. A bike standing in the courtyard because of a twenty-minute job costs more than any tool.

Where you can do the work yourself in Berlin
