GBFS & Data Principles

The General Bikeshare Feed Specification, known as GBFS, is the open data standard for bikeshare. GBFS makes real-time data feeds in a uniform format publicly available online, with an emphasis on findability.


About GBFS

Under the NABSA’s leadership, the General Bikeshare Feed Specification (GBFS) was developed by a cross-sector team of bikeshare system owners and operators, application developers, and technology vendors. Over 230 bikeshare and scooter systems worldwide have adopted GBFS since its release in November 2015.

GBFS is intended as a specification for real-time, read-only data – any data being written back into individual bikeshare systems are excluded from this spec.

The specification has been designed with the following concepts in mind:

  • Provide the status of the system at this moment
  • Do not provide information whose primary purpose is historical
  • The data in the specification contained in this document is intended for consumption by clients intending to provide real-time (or semi-real-time) transit advice and is designed as such.
How is GBFS different from MDS?
  • GBFS focuses on data for the end user, while MDS is used by regulators for management of free-floating mobility devices in the public right of way
  • GBFS focuses on publicly available, real-time data, while MDS focuses on historical data
  • GBFS is currently specific to micromobility, while MDS is intended to include any Mobility As A Service device
  • GBFS is a requirement within the Provider feed of MDS

Help Shape the Future of GBFS & Open Data for Bikeshare

NABSA is excited to begin our work to update and enhance the General Bikeshare Feed Specification (GBFS). NABSA has selected MobilityData to support GBFS as NABSA’s data consultant for this project. MobilityData works to improve the coverage, completeness, and quality of mobility data standards around the world, including the General Transit Feed Specification (GTFS).

Our goals for this project are: 

  • to enable new features in bikeshare systems and applications through data standardization, 

  • to protect traveler privacy, 

  • to support data needs for oversight and planning, and 

  • to make GBFS easier to implement through specification reference clarity improvements and best practices development.

We hope you will share your valuable expertise with us!

Please take a short survey about your experience with GBFS as a developer or data contributor. It will take about ten minutes.

Through this survey, NABSA aims to better understand the business and technical needs of your organization, as related to the General Bikeshare Feed Specification (GBFS).

You can also head over to the GBFS improvement conversation happening on GitHub to chime in.

View NABSA’s Webinar on MDS and Emerging Dockless Data Standardization from February 2019

This webinar explained what MDS is, why it was created, and how it compliments the GBFS standard. Two cities at the forefront of dockless data collection told members how they are doing it, and MDS creators discussed what is being done about user privacy.
