Singapore has its trishaws, Bordeaux has the tram, London has big black cabs, Sydney has the monorail, and Cape Town has... Rikkis! By all accounts, this is the way to get around the city - far safer than minibus taxis, much cheaper than standard taxis, and way more fun than walking, the Rikkis operate all around the city, and will even take you to some of the big tourist attractions around greater Cape Town, like Kirstenbosch and Cape Point.
I have to admit that I've never actually been on one (since we're always in our car), but I think I'm going to have to try it out some day soon. If you've travelled on a Rikki, please leave a comment and let us know how it was...
