They designed the bike as part of their Feats per Minute project. The tempo of your bike ride determines the beats per minute you produce, so pop and hip hop records, which are usually between 90 and 130 BPM, should be easy to play at speed while you ride.
The bike contains an amplifier and is supported by a nine volt battery to give the amplifier a sufficient energy boost to play the records out back through the sound horn.
