Flat tyre in Berlin — what to do?
In short: Flat tyre: remove the wheel, inspect the tube, find the cause inside the tyre (or you'll flat again in minutes). In our workshop we always replace the tube — from €15 (brought in) or from €20 on the complete bike, ready in about 15 minutes. Emergency? Give us a quick call.
A flat tyre is as much a part of everyday cycling in Berlin as the cobblestones in Kreuzberg. Glass shards on Falckensteinstraße, construction kerbs at Kotti, tiny wire splinters around Görlitzer Park — Berlin's streets are not kind to bike tyres. This guide gives you a clear step-by-step repair walkthrough, an honest assessment of when DIY makes sense and when it doesn't, and our recommendation for tyres that are genuinely puncture-proof in Berlin.
Got a flat right now? First steps:
- Stop immediately. Riding on the rim will ruin the wheel — and then the repair costs many times more.
- Assess the damage roughly. Small hole (slow leak) or open cut (goes flat instantly)? A cut in the tyre casing makes continuing unsafe even after patching.
- If you have tools with you: swap or patch the tube (see the guide below).
- If not: walk the bike or take it on the BVG outside peak hours. We're at Friesenstraße 24, Mon–Sat 9 am–9 pm.
Fix it yourself or go to the workshop — what makes sense?
The answer depends mainly on how serious the damage is and how comfortable you feel with the tools. Here's an honest assessment from us as a workshop:
DIY makes sense
- • Small hole (single thorn or shard)
- • You have a spare tube, tyre levers and a pump
- • Front wheel (easier than the rear)
- • Bolt-on or quick-release wheel, no internal hub
- • You know your tyre size
Better take it to the workshop
- • Tyre is torn or the tread is visibly worn through
- • Rear wheel with internal gearing, belt drive or e-bike motor
- • Multiple flats in a short time on the same tyre
- • Very wide tyres (cargo bike, fat bike) — hard to balance
- • You want to switch to puncture-resistant tyres at the same time
Replacing a bicycle inner tube — step by step
With a bit of practice you can swap a tube in 15 minutes. You'll need two tyre levers, a pump, a correctly sized replacement tube (the size is on the tyre sidewall, e.g. 28 × 1.75 or 700×35C) and ideally a rag.
- 1
Remove the wheel
Flip the bike upside down or place it on a repair stand. Open the quick release or loosen the axle nuts. For a rear flat, shift into the smallest gear first so the chain is easier to re-fit afterwards.
- 2
Remove the tyre
Let all remaining air out of the inner tube. Lever one side of the tyre over the rim edge using two tyre levers. Carefully pull out the inner tube — push the valve through the rim hole last.
- 3
Find the damage
Inflate the tube slightly and hold it near your ear, or submerge it in water — bubbles reveal the hole. Inspect the inside and outside of the tyre centimetre by centimetre for glass, wire or thorns. If you don't remove the foreign object, you'll get another flat within minutes.
- 4
Patch or replace the tube
For a small hole: roughen the area, apply a thin layer of vulcanising solution, let it tack up, then press the patch on firmly. For multiple holes, cuts or a damaged valve, a new tube is the better call — it costs under €10.
- 5
Mount the tyre and inflate
Slightly pre-inflate the tube, seat it in the rim bed, then work the tyre back on by hand (not with levers — the tube can get pinched!). Check that the tyre bead seats evenly all the way round. Inflate to the pressure printed on the tyre sidewall (city tyres typically 4–6 bar).
Which tyres are genuinely puncture-proof in Berlin?
After ten years running a workshop in Kreuzberg we have a clear picture of which tyres hold up in the city — and which don't. Here are our honest recommendations for everyday bikes in Berlin:
Schwalbe Marathon Plus
The classic for everyday Berlin riding. 5 mm thick puncture-protection belt, lasts 8,000 to 12,000 kilometres under normal use. Slightly heavier and a bit sluggish off the mark, but extremely reliable. Our no. 1 recommendation for city and trekking bikes.
Continental Contact Plus
Good puncture protection, lighter and slightly more responsive than the Marathon Plus. Solid value for money. A great alternative if you want the bike to roll a little sportier.
Schwalbe Big Apple / Big Ben
Wide, supple tyres for comfort on cobblestones (Bergmannstraße, Oranienstraße). Slightly less puncture protection, but a very pleasant ride feel. Popular on Dutch bikes and cargo bikes.
Frequently asked questions
How much does an inner-tube change cost in Berlin?
At BikeShop Friesen in Kreuzberg, material included, from €15 (wheel or tube brought in) or from €20 on the complete bike. Puncture-resistant tubes or unusual sizes (e.g. cargo bikes, child trailers) cost a little more. The swap usually takes 15 to 20 minutes and is done in the morning without an appointment.
Do you patch tubes in the workshop?
No — for punctures we always replace the tube. It's more reliable long term than a patch, and a new tube only costs a few euros. You can pick up a patch kit at the shop for on-the-road repairs though.
Which tyres are most puncture-proof in Berlin?
Schwalbe Marathon Plus and Continental Contact Plus are the standard for everyday Berlin bikes — both have a thick puncture-protection belt and typically last 5,000 to 10,000 kilometres. For comfort on cobblestones the Schwalbe Big Apple is a great choice.
What do I do if I get a flat while out riding with no tools?
Don't ride on the rim — it will ruin the wheel and make the repair far more expensive. Walk the bike or take it on the BVG (outside peak hours). We're at Friesenstraße 24 in Kreuzberg, Mon–Sat 9 am–9 pm.
Why do I keep getting flats on the same tyre?
Three common causes: a foreign object is still lodged in the tyre and punctures the tube again every ride; the rim tape has shifted or is faulty; or the tyre has reached the end of its life (cracks, thin tread). More than 2–3 flats a month on the same tyre means it's time to switch to a puncture-resistant model.
Can I get an inner tube out of the tyre without tools?
With very soft city tyres it's possible by hand with some practice. For hard or new tyres, tyre levers (2 plastic ones) are almost indispensable. Regular cyclists should always carry tyre levers, a mini pump and a spare inner tube.
Flat tyre in Berlin-Kreuzberg?
Just drop by our workshop at Friesenstraße 24 — no appointment needed in the morning. Tube swap in about 20 minutes from €15 (wheel brought in) or from €20 on the complete bike, material included.
