here are some photos of my trike under construction. its based on the T42 at www.mride.se , but it is built around a single seater cockpit, any passengers ride the bike.

Certainly a novel design but I can't help feeling that passengers are going to be too high for comfort, handling or styling.
It might be that your mockup pic is not to scale unless your driver is very petite Probably best to make it a single seater IMHO.

Passenger might not feel too safe there!

Bikes lean in corners and therefore centrifugal force has a part to play in riders/passengers staying on board. Your car will corner flat and that might just push a passenger of - especially if they can't 'feel' the way the vehicles going.

On the otherhand just leaving the bike seat in place might avoid an argument at a trackday the 'look it can't be a single seater there are two seats!' defence

Looks interesting, I've always liked trikes and the T42 is a beast (though I've never been too sure about the wheelarch styling personally).

there was a link to a very similar project on ebay a few days ago, was that the one your copying??

the frame looks very good so far.
I think that that Mride is too long. Proportionally and physically. Will your ride be shorted wheelbase?

you've transposed the bike picture, or is it an Erever?
