As soon as Aliseta sees the red bicycle, she knows it's the one for her.

But she doesn't know that Big Red has travelled across the ocean from America, where it once belonged to Leo.

He rode the red bicycle everywhere - to school, the swimming pool and football practice.

Leo was sad to have outgrown his bike, but found out he could donate it to someone who could really use it.

Now in Burkina Faso, Big Red helps Aliseta haul goods to the market and watch over her family's sorghum field.

But the red bicycle still has another purpose to fulfil.

Who will ride the red bicycle next? What will it be used for?In many parts of the world, bicycles are the best mode of transportation for bringing crops and goods to market or travelling on rough roads betwen remote villages.

Now charities in the developed world are ensuring our old bicycles find a new lease of life and are put to good use in these far away places.

The Red Bicycle is the story of how one ordinary bicycle - and a child's desire to make a difference - can change lives across the world.
