The Bicrophonic Research Institute (BRI) is an organisation that makes sound and music with people and places to play from bikes ridden by you the cyclist.

Over eleven years of international projects we have developed the sonic bike to do this.  A bike with two mounted speakers on the front and GPS receiver and Raspberry Pi computer on the back. With our bespoke mapping software, different sounds are linked to different places meaning that the interactive music played by the bike changes dependent on where the cyclist goes and how fast they pedal.

Not an app and free of the internet, the sonic bike creates an outdoor listening experience for everyone – reaching new audiences on the street or hillside, far beyond the confines of concert halls and galleries.

Established by Kaffe Matthews and Dave Griffiths in 2013, the BRI works collectively from London and Berlin labs, undertaking multiple projects annually, each one realising new site-specific music made through residential collaborations with producers and communities.  Politics, time, cycling possibilities, architecture and finances all bare on each project, making them utterly contemporary.  Alongside, we run local workshops in sonic bike making and open source development, all information of which is shared online.  These projects are resulting in the growth of independent sonic cycling hubs worldwide – currently in London, Finland, Houston, Brussels, Berlin and Magdeburg.



BRI artists and coders have interdisciplinary expertise with all age ranges and abilities, able to design with children or deliver lectures at cutting edge conference, industry or community centre. Audio awareness, listening and music making across all genres and abilities is encouraged and supported.

  • Lisa Hall

    A sound artist based in London, Lisa studied at London College of Communication and has worked with a number of art organisations over the past 10 years including CRiSAP and UAL. Lisa’s art work explores how we connect with the spaces and people around us by hijacking headphones, hiding speakers in trees, ringing bells online, writing architectural plans, drawing blue prints and blowing bubbles.

  • Monse Lozano

    An electrical engineer and musician based in Houston, Monse is committed to bringing awareness to engineering through art. This passion led him to create a non-profit organisation Vampire Squid Labs and to join the BRI, all in addition to his job at NASA Johnson Space Centre. He hopes that sharing a creative use of engineering through art will inspire individuals and communities to learn, conceptualise and create.
