Designer Szymon Hanczar's perfectly named We Never Give Up! sled has the traditional form factor of a winter wonderland ride, but to accomodate recent global warming trends, it comes with casters so it's not dependent on snow.
It's made from powder coated steel, with a lovely wood slat seat and a strap for pulling it up a hill. While it seems better suited for cities like San Francisco where there's hills a-plenty, it would probably be just as enjoyable when towed by a Vespa. He just needs to beef up those wheels which look like they're going to be sheared off by the first pebble. [Szymon Hanczar via Design Milk]
