"Two wheels side-by-side, 9ft in diameter, joined by a differential
axle which the rider swings beneath. You steer it with the brakes
(like a tank) and itıs very big, very fast and very clever. Indeed
you might say it gives a pretty good head turning circle. The
Dicyclette was built by Maik ter Veer and Fred Abels in Amsterdam
and is in England for itıs first ever trip outside Holland. You
just gotta see this one, then youıve just gotta have a go."
