Those interested in the state of the art in bicycle technology, I was 
impressed by the collection of vehicles at a corner bike shop in Amsterdam
during a research trip there last summer. Some of these were of the owner's
design but mostly they were pulled together from other builders around
Europe.

Some of my favorites were: a tandem in which the front rider is a small
child (the front wheel is steered from the rear seat), several versions of
an extra long wheelbase bicycle for carrying two children or a big cargo
bin, bicycles with internal hub gear mechanisms (like the classic British
three speeds) up to 21 speeds (non-overlapping, unlike deraileur systems), a
tricycle (two wheels in front with a basket) with a three speed electric
motor assist, and my personal favorite, a bicycle bus for carrying 6
toddlers under a canopy in front of the driver. I believe that several
models were available with integral or add-on electric assist motors.

I was amazed both by how suddenly obvious it was that the history of the art
of bicycle design still remains largely in its infancy, and that the
innovators of the North American bicycle world had been left so completely
in the dust by what I saw.

The owner of the shop, Jan Willem Deymann, mentioned he was working on a web
site but my search came up with nothing. He also insists on staying away
from the business of exporting given the hassles, so those of you beyond
bicycling distance to Amsterdam, don't get your hopes up too much. Maybe he
can be persuaded to put out a catalog. Here's the info:
