I'm assuming you're looking for a fast road/tri bike with a short top tube, comfortable ride, and handlebars set approximately level with the saddle.
My wife is 5'1" and just got an XS Litespeed Bella (titanium) with 650c wheels. It has a 49.5 cm top tube and a 70mm stem. With the standard 105 9spd group, it was priced at $2700 CDN at our LBS in Hull (my wife upgraded to Centaur).
Prior to the Litespeed, she was riding a custom 1990 Marinoni with a 700c rear wheel and 650c front. Marinoni is located just outside of Montreal and makes standard and custom bikes with 650c wheels for reasonable prices marinoni.qc.ca05 en geometrie.aspOpen ↗. Here's the price list from a large dealer in Toronto bikespecialties.compricechart.htmlOpen ↗.
We wanted to stick with 650c wheels to reduce pedal / front wheel overlap and steep seat tubes / slack head tubes that result from using 700c wheels on really small bikes.
Of the off-the-shelf bikes available in the Ottawa area, here are other bikes with short top tubes (48.5 - 49.5 cm) and low standover heights (i.e., 68 cm or 27"😉 that we found. If you live in a larger city, you should have even more choices to test ride.
