The #transmission..
I’ve #pirated the rear end of a #garyfisherbikes #Joshua X-1.. it’s called a “URT” or.. Unified Rear Triangle as the Bottom Bracket (where the crank arms meet) and the Rear Hub are connected in one rigid triangular configuration that is, then, floated against the mainframe by a pivot point and shock.

**but.. GEARS on a boat?**
I decided to use gears because our bodies go through physiological changes in energy levels throughout the day so, while I might not be pushing up hills, I want to make powered progress through pedaling all day long.. the gears mean that when I’m energized, I can flip it to 9th and CHUNDER.. and when I’m gassed.. I can slip it in to first and still be pushing my boat forward!
So, the trick is.. to build a solid enough mount that the URT is fixed nice and sturdy- like to the cockpit floor. I see “pouring epoxy” in my future.
