I can change from bike to trike (and back again) in less
than a minute.
I have only one front part and four rear parts: Two bike
rear parts (that is: with one wheel) and two trike rear
parts (with two wheels).

So if you have a trike, you can decide to buy (or build) a
bike rear part, so that you have both. Both rear parts have
the universal connection system. It is even possible to
attach a Flevo RACER front part to a trike rear part if you
would like to do that.

The difference between the both rear parts is of course that
the Trike has a Duschar joint and the Bike has not.
(Probably you know that my trikes have no Duschar joint, but
that is an exception. My trike rear parts have the two hinge
functions separated, and the sideways tilting hinge is much
lower than in the original trikes, as is explained in
http://wannee.nl/hpv/variatie/e-var-6.htm)

Cheers, Erik Wannee.

PS My second trike rear part can only be found on a Dutch
language page: http://wannee.nl/hpv/oefentri/
I built it especially for people who want to learn to ride a
FlevoBike. Because the tilting hinge is so extremely low
above the ground, it rides almost like a Bike, but the only
exception is that you can stay upright with both hands
firmly on the handlebars. The frame is made from 2 mm thick
stainless steel so that 'first time' test pilots cannot
damage much to it. At this very moment, someone in the
Netherlands is riding his first kilometres on it. (People
can rent it during a week, together with an instruction
manual: http://wannee.nl/hpv/oefentri/oefentrike.pdf)
