Not to be confused with the Tricycle House, the Housetrike is a pedal camper with a unique form. It looks like a basic cargo trike at first, but extends into a lockable sleeper for one.
Not surprisingly, bicycle camper designers tend to borrow heavily from their motor vehicle counterparts. A little bit of digging pulls up bicycle-bound teardrops, fold-out tent campers, pop-tops, and even hard-sided trailers with above "driver" sleeping extensions.
In developing the Housetrike, Dutch artist Bas Sprakel also borrowed a trick we've seen in the vehicle camper market, on everything from compact camper vans like the VW DoubleBack to massive 8x8s like the Unicat MXXL 24 AH. That particular trick, the sliding camper extension that increases living space while keeping travel configuration more compact, seems well-suited to a small trike trailer.
