I just received my Motobecane Mirage S and to tell you the truth; the Standover height listed for my 50 cm is 70.7. The actual with tires inflated at the front of the saddle IS about 75 cm, so, it's off by about 2".
With that said, I can easily stand over it without hurting myself or any discomfort, while I am wearing shoes. I have an inseam of 29" and I'm 5'5" so the reach is good for me. The seat post of 350 mm (clamp at top inclusive) is only up about 130 mm (13 cm or 5") I already had it out for a little test and it was comfortable.
My nieces husband thought that Motobecane is an expensive bike but when I told him what I paid his draw dropped!
Assembly was easy; I took my time and did very minor adjustments; I have a repair stand (Confidence from Amazon, which works just fine; even for my wife's 39# cruiser!) which made the process easy.
I am really happy with the bike, too! I cannot wait for the weather to warm up here in Michigan!
All in all it's a great bike!
