This is an idea I had for a new design.  The chassis would be LWB and made of composite panels forming a box that the rider sits in.  At the front and rear are bulkheads that for the cross-sectional shape for a thin glass/foam sandwich fairing that connects the two bulkheads with a hole in the top for the rider to enter/exit and stick his/head out while riding.  A windshield will be stuck on top of the fairing hood.  It is my hope to make the fairing without using molds.

My initial plan is to use a linear drive because it 1) allows the front to be much lower 2) provides for a completely clear floor and center section 3) is something no one else has had much success with and I'd like to give it a shot.  The pedals are mounted to drawer slide tracks bolted into the sidewalls.  A cable leads back from each pedal, attaching to a chain segment which goes over the cog on either side of the transfer shaft.  The drive cables form a complete mechanical loop to permit ankling on either pedal.  If the linear drive doesn't work I have several alternatives in mind.  The front and rear subframes will be MAPP-brazed steel tubing.  It is my intent to have a second rear frame that carries 2 wheels so you can make this a trike when you need to.  I realize this isn't complete, I will add more when I get the time.  I've made a 1/5 scale cardboard model of the chassis and I will try to get a picture of that put here.  I could really use some CAD help if anyone in the Seattle area is interested.

I've designed it to be simple and nexpensive to build.  I plan to mock up the chassis in plywood for placement of the parts and rider fitting.  I hope to begin work on that this week.  I've already considered modifications, such as moving the front wheel back to the front bulkhead to make it a SWB.  One advantage of this design is that the ground is the limit to how low you can go, yet there are no bends in the drivetrain.
