After making a tandem bike a few years back, I decided to fab something else up.
This time I was going after something with four wheels, and recumbent (almost) style seating. After sorta designing it and planning it out, I thought about making it a two seater. Then somewhere in the process I decided I might as well go for 4 seats, which brings me to a small hiccup with the drive system. I haven't been able to find too much about this online.
Here is a simple layout of basically what I'm trying do.
Yea, I have alot of chains, but I don't know how else to work around that without seriously complicating things. Any suggestions? Keep in mind I'm trying to keep a solid rear axle. I was also considering a suspension, but I'm not quite sure how that's gonna work out..
