Hi. We are hoping to bike across America on recumbents (which we have never done). So I need advise from all you experienced tourers out there what you have found to be a durable, reasonably comfortable recumbent for a 4000 mi. ride. From what I have read, disk brakes (especially for those long mountain down grades) and LWB seems to be what we think we would want. But as for brands and models, I'm still undecided. Sun? Rans? Bacchetta? We are hoping to stay under $1500 per bike. I am a 6'2, 54 year old male, and my wife is 5' and 50 years old (if that helps with frame sizing). What would you recommend (and not recommend)? Thanks so much in advance.
