Has anyone ever messed with designing a semi-recumbent? I am looking at doing a sociable tandem as my next project and was thinking semi-recumbent would be nice for an easy to get into and out of bike.

This is a youtube vid I found -

and there are some feet forward cruiser bikes that might have usable dimensions...

I am mainly wondering what kinds of issues I will have with this design? I am thinking it will have to be fairly long and wide wheelbase to make it stable (especially if one person decides to hop off) and I realise that it is not "out of the wind" as much as more recumbent designs, but this is more of a cruise-a-long kind of bike. Any thoughts?

These AZ plans would fall into that catagory more or less:
Meridian touring, Tourmaster, Wildcat Recumbent, Delta Runner Trike, Loderunner Trike, Loderunner Tandem, Tradewinds Tandem, Voyageur Lwb and Voyageur Trike, possibly even the Bandito Recumbent and don't forget the Kyoto Cruiser Tandem.
All of these are kind of semi recumbent as far as the riders position goes. The trike designs would take care of stability issues if someone hopped off. -Taylor-

Actually I was sceptical at the large list you presented as being close to what I was looking for, but the more I look at the differnt riding positions the more I agree with you. The tourmaster is probably closest to the postion I am thinking of, so I will be looking more into that design. Thanks!

Personally, I think the "Meridian Touring" of Brads, is really close to that one in your link. Just a bit different, but very similar.
I've got one I started last year, then sat it aside to work on some "honey-do's".
Now I want to finish it so I can ride it! -Taylor-

That is what this group is for! To keep you focused on completing and enjoying your projects. We all have tons of stuff to do in our lives, and all of it is important, but when you decide to take on a project you have to take the time for it. Having a support group like this is invaluable! Thanks everyone.

The designs I would study are the Easy Racer Tour Easy, Rans Stratus, and the variations that A. D. Carson builds.

I agree with taytayou812, the youtube bike (s17) looks like a somewhat modified Meridian with underseat steering. If you want to build one, I have some used 12" wheels I would let go cheap. The only thing I would caution against is keeping the seat ahead of the rear axle, so it's not prone to wheelies.
