I love these eco-bikes. You find them in most of the big European cities now, and they are a great way to get around. You use a mobile app (of course) to register a bike, and off you go. When you’re done you pop it into a rack and you’re done.
They have a similar concept with scooters which you can leave anywhere when you’re done, and the app tells you where the nearest scooters are.
A great idea, but I somehow think the South-African public isn’t quite ready for them…
