That looks like the what BethZ's bike has on it when you zoom in on the pic.. Figured you'd have the info.
Beth, if you are comfortable riding the bike otherwise I wouldn't worry about the stand over height. I am much more comfortable riding bikes that are taller than would normally be recommended for someone of my height and some of them have "zero clearance".
I haven't had a ride of more than a few blocks around town this year. We have had snow on the ground since January 1 and it's been consistently 10-15 degrees below normal with only a a handful of above average temperature days.
