Hi and welcome. Here's my take on it...
It might be worth it for you to take a road trip to the Terry dealer.

In general, some shops don't stock smaller bikes because there isn't as big of demand for them. Or, they will only order one in on condition that you purchase it. ( right) While it's getting a lot better now, it will really vary from shop to shop.

Back to the Terry. This guy may not get a whole lot of of it from Terry, and that may be the lack of enthusiasm... again, if he gets it together to bring it in for you, he doesn't have any guarantees that you'll buy it and that's his time and money. Just because he's on their list doesn't mean anything, really. This is why I think , if you must try the Terry, go to a Terry dealer that has something invested in the sale.

I'd certainly keep looking for a shop that understands the needs of the small rider. For example, one of my favorite shops here, the owner's wife is 4-11 and an avid cyclist.
