How long are these tandems,tire to tire?Is a mountain bike style shorter than a road style?So far no one nearby has one in stock,didn't see dimensions on bike specs.I was surprised to see I could pick up a LHS,Trek,Raleigh for only 1000.00 to 1200.00 bucks.Even more surprised actually scared to see the big box stores have them for 275.00 I'm going to try to rent one and get the bride on it for a couple of rides.It would be useless if she didn't enjoy the bike. Hmm I guess I could ask everyone's wife in my neighborhood to go riding.
