TIER

TIER Mobility was a Berlin-headquartered shared electric micromobility operator founded in 2018 by Lawrence Leuschner, Julian Blessin, and Matthias Laug, providing e-scooter, e-bike, and e-moped sharing across European and Middle Eastern cities. In March 2024, TIER merged with Amsterdam-based Dott to form the combined European micromobility champion that now trades under the Dott brand on ridedott.com, operating in 400+ cities across roughly 22 countries including Germany, France, the United Kingdom, Italy, Spain, the Netherlands, Belgium, Sweden, Norway, Finland, Denmark, Austria, Switzerland, Poland, Greece, Hungary, Israel, Saudi Arabia, Qatar, and the UAE. All public real-time data — fleet positions, battery levels, vehicle types, pricing plans, stations, and geofencing zones — is published via GBFS 2.3 (General Bikeshare Feed Specification) endpoints at https://gbfs.api.ridedott.com/public/v2/{system_id}/, with one `system_id` per city. There is no consumer authentication or paid API tier; feeds are open data consumed by city regulators, MaaS aggregators, and trip-planning apps.

TIER publishes 5 APIs on the APIs.io network, including Discovery API, Stations API, System API, and 2 more. Tagged areas include Mobility, Micromobility, Shared Mobility, E-Scooter, and E-Bike.

The TIER catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

TIER’s developer surface includes support, engineering blog, and 17 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/tier-mobility: open an issue to ask a question, or submit a pull request to add artifacts.
