Chuckles, I knew the $49. couldn't be per hour, but didn't get a chance to research anything else (I already had the site book marked).
Still, if the logistics could be worked out, using the figures you were given, a 14 day rental would be aprox. $1260. per person (her original question mentioned "a couple of bikes"). That's a lot cheaper than anything they could buy that would be ridable coast to coast. Add to the cost of the bikes what needs to be done to get them on the road. In NC, you have to have a NC address to register a vehicle. Different states have different requirements, but the bikes would still have to be legal to ride.
Myself, I wouldn't want the hassles entailed with buying and then selling a couple of bikes.
Perhaps it might be cheaper and less difficult overall to ship their own bikes over here for the trip. I'll try and look up some info later today.
ps: want to congratulate you on having an America in the perfect color scheme, 2 tone blue.
