I'm planning to trade up to a Rans Stratus XP from my Sun EZ Sport.
I test rode the XP; the only thing I couldn't fall in love with in one ride is the front end felt a little squirley. The slightest move of the handlebars seemed to translate into more steering action than I expected. I attributed this to the 26" front wheel compared to the Sun's 20" which I'm used to. This plus the fact the bike's seat and bars were not dialed in perfectly to suit me, and that I've only one year recumbent time under my belt.
Any XP owners here mind sharing your opinions about the bike? Would you buy one again tomorrow if yours vanished?
