I'm thinking about getting a trike (someday), due to the fact there is no 'learning curve for balance'. I'm 6' by 230 lbs. (yeah, I could stand to lose a few...) I checked out recumbents.com and they said that tadpoles were better for cornering at speed (makes sense), but that deltas were more stable at speed on the flats (not so much). I've been advised to stay away from the sun products. What about WizWheels or Actionbent? They're in my price range (so long as the wife doesn't catch wind, anyway!). I'm a slacker at heart, and the ability to park my bike somewhere and take a catnap w/o falling off appeals to me.
