You know, I look at the discussion of in-frame mounts vs GEBE rack type mounts, and I have to ask - WHY?
In-frame makes a lot of sense. It gets the engine mass low, it puts it in a semi-protected spot in the event of a spill, and it leaves the rear rack space for cargo. The GEBE ring doesn't care what angle the engine is at - what matters is that it be properly aligned and snug, to prevent belt jumping.
The tadpole I am working on is going to be GEBE powered, with the engine right at hub height straight ahead of the wheel, and the whole thing monoshock suspended. By putting a pair of identical sprockets on my pivot axle for the rear suspension I avoid the need for a chain tensioner, and the rear hub will be a 3 speed Shimano internal rear end. The seat will be on a short suspension rig, able to absorb yet more of the road shocks. A pair of front disc brakes, and a pair of headlights that mount to the upper ends of the kingpins will give me good visibility that steers with the trike - I figure on using a pair of 12 volt gel cell batteries in parallel to give me at least 8 hours of lights front and rear.
I was planning to construct an integral rear rack as a part of the rear suspension, but have decided that isn't necessary immediately - if my health ever gets to where I can do some long distance touring that will be time enough.
