In 2013, architect Aigars Lauzis went on an epic bicycle trip from London to Tokyo. It took four years, and Lauzis clocked 31,000 kilometers (19,263 miles).

The trip inspired Lauzis to invent the BeTriton, an amphibious bicycle-towed camper. It weighs 175kg (385 lbs), but an electric motor powers the camper, so it doesn't feel like you're towing anything.

The roof can be collapsed, providing a lower profile during towing. There are solar panels on the roof for charging the onboard batteries. This provides, Lauzis says, unlimited range on sunny days (though he doesn't say how long it takes to charge them).

So the crazy thing is, if you come to a body of water, you can cross it with your bike by using the camper as a boat. The tow bar becomes a bike rack, and the camper's batteries power the outboard motor.

There's enough room inside for a couple to sleep.

Here's the demo video:
