Oh, you mean the trike.
You know me and Jim, always searcing for good pulling ratios!
Seriously though it was just a thought that the two speeds of the tbox, 1.2:1 and 2.135:1, would give nice urban and motorway speeds. At 3500rpm I would get 42 and 75mph respectively.
I was also thinking of being able to tow a small trailer, with my tools, to the theatre to save driving the car.
Realistically I wouldn't need gears even if I was using the 7" motor from the tractor. I should have weighed that while it was apart as I could have designed around the 7" and moved one of the other two motors to the tractor.
I have been doing some more weighing (this is going to lead me to therapy!
) and in a seated position my own weight distribution is 12.8kg at my feet and 72kg at the seat with the remainder of my 86kg in the back rest. Given that I am going to be a significant proportion of the all up weight I figured that this would be useful.
I also want to get my own weight back down to 75kg where it was a couple of years ago. That is going to be harder work then building the trike.
You know, I was more surprised that the motorbike wheel weighed more then the big wheels I have for the tractor. I guess the aluminium rims I found in the scrap steel rims skip at the scrap yard was my benefit.
