Iím making a move from 2 wheels to 3 myself, pondering some of the same things on comfort,
There is also another option, which is converting your existing 2 wheeler to a reverse trike. A company named Endeavor will convert any bike to a front wheel trike for $9,600 plus shipping both ways. If you need reverse gear thats an additional charge.
I really like their conversions but if I can make a used Spyder work for me I can sell my existing 2 wheeler to cover the full cost of the Can Am, vs spending another $12k to keep my existing ride. Hopefully Iíll know by tomorrow which direction Iím going with things.
