Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-f4208fefc4211bf7 quantitative
has run since July 2009
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The operator's own site states "Seit 2009 ist StadtRAD Hamburg das führende Bikesharing-System in Deutschland" ("Since 2009, StadtRAD Hamburg has been Germany's leading bikesharing system"), confirming the launch year 2009.
Caveat
The cited sources establish only the launch year, 2009. None of the five listed sources names July specifically as the launch month.

Claim 2 clm-9308eba26dc8eb33 quantitative
operated by DB Connect under a city contract awarded for 2019-2028
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
KCW's write-up of the tender states directly: "Gewinner der Ausschreibung für die Laufzeit 2019-2028 ist der bisherige Betreiber – die Deutsche Bahn Connect GmbH" ("Winner of the tender for the 2019-2028 term is the incumbent operator, Deutsche Bahn Connect GmbH"), naming both the operator and the exact contract term in one sentence. The operator's own site separately confirms DB Connect's role by describing StadtRAD as part of "der großen Call a Bike-Familie, dem Bikesharing-Angebot der Deutschen Bahn" (Deutsche Bahn's bikesharing brand).
Caveat
Among the five listed sources, the specific contract term "2019-2028" is documented only by KCW, a transport consultancy publishing its own case-study page about a tender it advised on — that page reads as advisory/promotional material rather than a city or operator record, and would grade as a media-tier source on its own. Neither the city's own StadtRAD service page (hamburg.de) nor the operator's own site names the contract dates in the pages checked here.

Claim 3 clm-65afce95df0aced7 quantitative
About 4,300 bikes and 56 cargo pedelecs stand at nearly 360 stations
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The Hochbahn press release of 30 June 2026 states exactly: "Rund 4.300 StadtRAD-Fahrräder an fast 360 Stationen im gesamten Stadtgebiet stehen damit über eine einzige Anwendung zur Verfügung" ("about 4,300 StadtRAD bikes at nearly 360 stations across the whole city are now available through a single app") — matching the bike and station figures precisely. The Hamburg BVM service page adds the cargo-pedelec figure: "über 4300 Räder an über 350 Stationen sowie 56 Lastenpedelecs zur Verfügung" (over 4,300 bikes at over 350 stations plus 56 cargo pedelecs).
Caveat
hamburg.de's own page is internally inconsistent and, either way, gives a somewhat lower station count than the entry: one passage says "über 350 Stationen" (over 350) and another, undated news item on the same page says "knapp 350 Stationen" (just under 350). Only the more recently dated Hochbahn release (30 June 2026) matches "nearly 360" exactly; the difference is consistent with the network's ongoing station rollout rather than a contradiction.

Claim 4 clm-1c02e44dbd1c9b29 quantitative
the first 30 minutes are free
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
hamburg.de states directly, describing the April 2026 tariff update: "Wichtig: Die ersten 30 Minuten pro fahrt bleiben weiterhin kostenlos" ("Important: the first 30 minutes per ride remain free of charge") — confirming this is still current even as other tariff elements changed. KCW's 2018 tender report shows the same rule already applied at contract start ("first half-hour remaining free of charge").
Caveat
No claim-specific caveat recorded

Claim 5 clm-fac0bc7ac17d7d0d descriptive
Live per-station availability is published as open data through Hamburg's SensorThings API
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The dataset page describes exactly this, not merely station locations: "Der Datensatz enthält die Position aller StadtRAD-Stationen im Hamburger Stadtgebiet und die Anzahl der aktuell zur Ausleihe zur Verfügung stehenden Fahrräder und Lastenpedelecs" ("the dataset contains the position of every StadtRAD station in Hamburg and the number of bikes and cargo pedelecs currently available for rental at each"), delivered live "im JSON-Format ... in der SensorThings API (STA)" (in JSON format via the SensorThings API). So the API carries live per-station bike/pedelec counts, not just a static list of addresses.

Claim 6 clm-08a8aaa5a4146f40 quantitative
bikes became bookable in the hvv switch transit app in 2026
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
Hochbahn's press release, dated 30.06.2026, announces exactly this under the headline "StadtRAD jetzt in hvv switch: Mobilität in Hamburg wächst weiter zusammen" with the subhead "Ab sofort auch Fahrrad-Leihmöglichkeit in Hamburgs Mobilitäts-App" ("as of now, bike rental is also available in Hamburg's mobility app") — an immediate, 2026 rollout.

Claim 7 clm-55fd8bcaea256e88 quantitative
Operator reported rentals up 11% from March to September 2024 after the fleet was modernised.
Published field
impact · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The listed URL for this source (nachhaltigkeit.deutschebahn.com, .../stadtrad-angebot-in-hamburg-waechst-weiter-13565972) currently returns HTTP 404 — it appears to have been taken down or renamed since the entry was written. A search-engine cache of the same title ("StadtRAD-Angebot der Deutschen Bahn in Hamburg wächst weiter") and independent press coverage of what reads as the same DB Connect statement corroborate the figure: Radio Hamburg (04.10.2024), citing the operator, reports "Seit Beginn der Modernisierung der Flotte im März sei die Zahl der Ausleihen bis September um elf Prozent gestiegen", explicitly "teilte der Betreiber DB Connect mit" (as communicated by operator DB Connect) — a rise of 11% in rentals from March to September, described by the operator itself as running from the start of the fleet modernisation, i.e. a stated temporal correlation rather than an independently verified causal test.
Caveat
This is the operator's own figure, reported via press coverage, not an independent evaluation; the source treats "since the modernisation began" as the operator's own framing rather than a demonstrated cause.

Claim 8 clm-1e70236a71e0f4d0 descriptive
the city publishes live dock occupancy under an open licence
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this passport
What the mapping says
The dataset page is published by the city ("Veröffentlichende Stelle: Behörde für Verkehr und Mobilitätswende (BVM)") under the licence field "Lizenz: Datenlizenz Deutschland Namensnennung 2.0" — Germany's standard open-government-data licence (DL-DE-BY-2.0), which is Open-Definition-conformant and functionally equivalent to CC BY (attribution required, otherwise unrestricted commercial and non-commercial reuse). This is a genuinely open licence, and the dataset it covers is the live per-station bike/pedelec count described in the previous claim.
Caveat
No claim-specific caveat recorded

Known limits of this passport
  • Publisher names and source languages have not yet been classified; domains are recorded without guessing.
  • Existing source notes are descriptive locators, not page- or paragraph-exact citations.
  • A missing archive, publication date or content hash is shown as null rather than inferred.
  • The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
