CycloClean, a bicycle adapted with a pump and filtration system, is being deployed to help provide drinking water in places where it is needed through pedal power, with source water drawn from places such as rivers, ponds, swimming pools and even bathing water, providing the latter is free of bathtub agents.

Designed primarily for emergency use, with bicycles able to get to areas inaccessible to other vehicles, the filter system is attached to the rear rack, and comprises one pre-filter and three additional filters.

A user, powering the pump by turning the pedals, is able to produce six litres of drinking water a minute, which it says is three times the amount of drinking water that a person needs each day.

Made by Japanese company Nippon Basic, the bicycle costs ¥550,000, equivalent to a little more than £4,000. That may seem a hefty tag, but with the manufacturers citing a comment from Unicef that "1,900,000 children a year lose their life due to unclean water," its potential value is, quite literally, priceless.
