Dalian Nationalities University Chinese designers have developed a contraption called the Bike Washing Machine that contains a washing machine drum in its front wheel.
When ridden, the pedaling motion causes the drum to rotate, churning your clothes inside like a traditional washer. A generator inside the bike also creates electricity which can be stored for future use.
The device could be a solution for those who want both a washing machine and an exercise bike but cannot find space for both. The invention could also find use in remote areas where people do not have access to reliable supplies of electricity.
Generally, Bike Washing Machine combines a stationary bicycle and washing machine; you can exercise while at the same time simultaneously washing your clothes.
