We find out how kids from Spain to Scotland are joining together in long convoys known as “bike buses”. Teachers and parents accompany the joyful multitude of cyclists, which pick up children from pre-determined stops along the way.

And in Kenya, we look at a different kind of transport problem. Motorcycle taxis are used all over the world, but converting them to electric has proved a challenge.

But a new kind of business in Kenya has found a neat solution. They’re hiring pre-charged batteries to the drivers so they can swap them without waiting around for a charge.
