Washing Box / washing box

All of the tourists who travel by bike have a lot of dirty clothes during their long journey which they have to wash them by hand. To solving this problem they just need to buy a Washing Bike and a hubless bike so they just have to put their dirty clothes with a little water and washing powder in the box which will be placed in a wheel of hubless bike then they have to keep going and pedal. Finally when they arrived at their destination they just need to rinse their clothes.
