People will find any excuse to have a party, and any place to have one. Thankfully, a German company has come to all of our aid with Das PartyBike (seriously, that is what its called).
Designed to transport you while the party is going, Das PartyBike can carry anywhere from 10-16 people. And since you might want to enjoy the party yourself, a driver is included. Promoting itself as a mobile sound system and beer tap, Das PartyBike is available anywhere in Germany. No word on whether there are franchise opportunities in North America.
