FlevoBikes were a Front wheel drive center steered 2 wheel bike ,
there is no handlebar controlling the steering ... its all lean steered ,
and since the feet are also powering the front wheel , real tricky to master.
http://flevofan.ligfiets.net/?doc=ch4-01 1wheel driving from the front, 2 in back
might have velomobile applications in a 3 wheel type ,
100 years ago they figured out the 2 steering wheels need to turn at a different angle ,
not stay parallel, ala Christiania cargo trikes.
as far as Carbon fiber building look up Vacuum Bagging

the vacuum is what gets the air bubbles out .. the lightest structures use Pre Preg fabric
it is pre impregnated with the resin that is thermo setting , as I understand big users like Trek *
get the stuff refrigerated , so it wont cook early ..
then the vacuum bag scheme is made to go in an Oven, as it is hoovering out the air.
* Boeing and Airbus use a lot more of course. [and the Area 51 'skunkworks']
