description: >-
  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.
