That "Type 7" semi-recumbent thing looks like a comfortable bike. Does the fairing decrease the wind resistance enough to account for its extra weight? I'm a little skeptical about that.
And I wouldn't call it a spoiler.. spoilers are for cars that generate enough lift (because cars are shaped sort of like wings) to affect handling, so they direct some of the wind force downwards to compensate. You would definitely not want a spoiler on a bicycle, it'd just cause more resistance.
Also, I don't know if you're looking for feedback or something, but I'd feel really silly riding around in a bike that looks like a cross between a comfort bike and a jetski. Just sayin'
