Buying a used bike in Berlin — how to make a great purchase

Last updated: 3 July 2026

In short: When buying used, check: frame number (Rahmennummer) + provenance, condition of chain/cassette/brakes, smooth shifting, bearing play. Fair prices: solid everyday bike €200–400, used e-bike at least €800. We sell used bikes that we have inspected and refurbished.

A used bike in Berlin can be a real bargain — or an expensive disappointment. In our workshop on Friesenstraße we see bikes every week that arrive straight after purchase: stretched chain, buckled rim, broken brake. This guide shows you where to find good used bikes in Berlin, what a fair price looks like, and which 10 points you absolutely must check before buying — so you don't end up paying more than for a new bike.

Eyeing a bike right now? Have it checked first.

We inspect used bikes before purchase in our workshop in the Bergmannkiez — frame, brakes, gears, bearings, tyres. You get an honest list: what's good, what will cost money soon. So you go into negotiations with your eyes open.

Where is the best place to buy a used bike in Berlin?

Berlin offers many sources — each with its own pros and cons. An honest overview:

Bike shop (recommended)

Inspected and refurbished. Slightly more expensive — but no risk of stolen goods, hidden faults or missing receipts. BikeShop Friesen regularly stocks inspected used bikes.

Kleinanzeigen & eBay (Germany's Craigslist-equivalent)

The biggest selection in Berlin, but also the most risks. Always collect in person, never transfer money in advance, test ride on the spot, and ask for photo ID and (if possible) the original receipt.

Flea markets (Mauerpark, RAW, Boxhagener Platz)

Atmospheric and often cheap — but be careful: very cheap bikes under €80 are frequently stolen in Berlin. Rule of thumb: if you can't see the seller's ID, walk away.

Lost-property office & police auctions

The BVG lost-property office and Berlin's central lost-property office (Zentrales Fundbüro) regularly auction unclaimed bikes — legal, cheap and with no theft risk. Dates are listed online at berlin.de.

The 10-point checklist before you buy

Work through this list calmly during your viewing. Give yourself 20 minutes — it can save you hundreds of euros in repairs later.

Check the frame number (Rahmennummer). It sits under the bottom bracket. No number, an illegible one, or one that's been filed off = walk away.
Frame for cracks & dents. Especially at weld seams, the head tube and seat tube. For carbon: tap with a coin — a dull sound suggests an internal crack.
Test the brakes. Pull the lever — does the brake bite firmly with no rubbing? Pads still >2 mm? On rim brakes: is the rim surface still flat (not hollowed out)?
Run through all the gears. All gears clean, with no clicking or jumping? Derailleur hanger bent? (Look from behind at the rear derailleur.)
Check chain wear. Lay a ruler along 12 links — if it's noticeably more than 12 inches, the chain is worn out. New chain + cassette: ~€70–120.
Check the tyres. Cracks, worn tread, brittle sidewalls? New tyres: €25–60 each.
Wheels for buckles. Lift the bike, spin each wheel and look down at the brake pad — does it wobble? Truing from €25, spoke replacement from €15 per spoke.
Check the bearings. Wiggle the handlebars side to side — does the headset click? Turn the cranks without the chain — does the bottom bracket crunch? Bearing replacement is expensive.
Lights & legal requirements (StVZO). Do front and rear lights work? Are reflectors in place? Without lights in Berlin things get costly fast (fine + retrofit from €50).
Take a test ride. At least 5 minutes, with acceleration, braking, gear changes and riding no-hands. Vibrations? Noises? Does the bike pull to one side?

What does a good used bike cost in Berlin?

Reference prices for well-maintained, road-ready bikes (as of 2025/26):

Bike type	Fair price	Pay special attention to
Basic city bike	€150–300	Rust, lights, internal hub gears
Trekking / city bike	€250–500	Chain, cassette, brake pads
Gravel / road bike	from €400	Carbon frame, groupset condition
Mountain bike	€300–800	Suspension fork, rear shock, wheels
E-bike (with battery test)	from €800	Battery capacity, motor mileage
Children's bike (16–24")	€60–150	Brakes, rust, bolted connections

If an offer is significantly below these figures there's usually a reason: a serious fault — or a dubious origin.

Frequently asked questions

FAQ: Buying a used bike in Berlin

How do I tell if a used bike is stolen?

Key warning signs: no frame number or one that's been filed off, a cut lock still on the bike, the seller has no receipt and won't show ID, meeting only late at night in remote spots, price far below market value. Always ask to see a photo ID and (if possible) the original receipt — and check the frame number (Rahmennummer) for free in the Fahrradpass (bike registration) database of the Berlin police.

What is a fair price for a used city bike in Berlin?

Simple city bike in good condition: €150–300. Well-maintained trekking bike: €250–500. Gravel or road bike: from €400. E-bike (with battery test!): from €800. Anything significantly below these figures is either worn out — or suspicious.

Can I have a used bike checked in your workshop before I buy?

Yes. We inspect used bikes before purchase for a small fee (~€25) — frame, brakes, gears, bearings, tyres, safety. You get an honest assessment of what will need money soon. Just bring the bike by in the morning.

Do you sell used bikes yourselves?

Yes, regularly. We take bikes in part exchange or buy them outright, inspect and repair them before selling them on. Which models are available changes weekly — come in or call us.

Is a used e-bike worth it?

Only with a battery test. A new battery costs €500–900; an e-bike without a working battery is almost worthless. Ask for the battery production year (label on the cell), check the remaining capacity and the charge cycle count via the display or our diagnostic tool (Bosch / Shimano).

What are the most common faults on used bikes?

Worn chain and cassette (together ~€70–120 to fix), worn brake pads, buckled wheels, creaking bearings, old cables, broken lights. Sounds like a lot — but knowing this before you buy lets you negotiate fairly rather than being annoyed afterwards.
