In the USA, we mount electronic sound systems to the backs of our bikes. Here’s how they do things in the Old Country.
“Backies” is the Euro-English term for the practice of riding while seated on the rear rack of a bicycle. A couple of crazy fun bike guys in Estonia have created a pedal with fold out pegs so your passenger can act as a stoker as you captain the bike and he plays a tuba. The below video demonstrates the concept nicely.
€69 purchase from Virguvant.com includes worldwide shipping cost. Be sure to read the specifications page to ensure the pedal fits your bike (it probably will) and for reminders that a metal post sticking out of your pedal will affect your turning radius and passing distance.
