It can only fail.
The idea isn't half bad, but, like a lot of Sinclair's brainwaves, the execution is awful.
Its a recumbant bike. Nothing wrong with that idea, but the upright seating position means that the main advantages of a recumbant, streamlining and the ability to provide more effort to the pedals, are negated.
Its got a roof. Nothing wrong with that, but its profile means it will have horrific windage. I wouldn't want to ride that in traffic where high sided vehicles sweeping past will blow the thing all over the road. Or in anything other than a light breeze. Also the open sides and closed back mean that trying to go against a head-wind will be like trying to ride through a brick wall.
It has power assistance, but the power is severely lacking, particularly considering its high drag and weight (its over double the weight of my Dahon Espresso folder (13Kg).
The small wheels will also provide poor stability.
All in all, I would imagine this would be a frightful thing to ride around on (in?), with respect to comfort, performance and safety (you may have a roll cage, but it looks pretty flimsy and it will be blown all over the road. I also imagine that flying shards of that shell would be pretty nasty in any smash).
