Dutch designers Merel Slootheer, Pieter Frank de Jong and Liat Azulay have created a bike that plays music. Feats Per Minute (fiets is Dutch for bicycle) was designed using a basic $90 bike and with a few changes converted into a record player on wheels.

Simple alterations to the bike’s structure makes it easy to change records, and a few tweaks to the “crank of the bike and the chain” ensures records don’t skip. The record screws onto the bike frame with a small cap, and the needle is spring-loaded to keep it steady. To allow (or force?) pedestrians to hear your tunes as you zoom by, the designers installed a megaphone-style amplifier made out of plumbing materials.

In order for the records to sound as intended, you need to be a real steady peddler.
