Here is another "Camper Bike" but with a different design. You could actually stay a night in it for $10.

Even better is the camper kart http://www.kevincyr.net/index.php?/ongoing/camper-kart/

Changing a tire looks like an ordeal.

he probably could use a standard car jack.

i'd imagine biking up hills would be the true ordeal.

Even going down hills would not be much fun... if you hit a curve with any speed at all, off the side of the road you go. Also, any good side winds look like they'd push the thing around.

At least you can pedal in the shade!

Undoubtedly. I'd like to see a more modern version.

Creative, I like it (whether it's truly functional or not).

Burning man will never be the same. Any hackers going, btw?

No brakes?

Probably coaster brakes. Turn the pedals backward a bit, and it stops the wheel, as found on kids bikes and beach cruisers and the like.

There's also some sort of cable running down the center from the front to back...but I can't really determine what that's for. Unlikely to be gears, though.

While this thing here is only a work of art there are many cargo bikes out there that can carry a substantial load, the Yuba can up to 300kg. http://www.yubaride.com/

Can't handle anything like 300kg, but tons of people here (in Holland) are running around with these:

As well as oversized tricycles to move really heavy objects.

Yeah, the classic. We have plenty of those around here (Berlin) as well but they're quite expensive (hand made!). Other cargo bikes get manufactured and are thus cheaper.

It gives "tipping" a new meaning...

I can't vote this up enough
