I'm 4'11 with a very close inseam, and finding a "stock" bike was a bit of a nightmare. My Liv Beliv has 700c tires and I do get toe overlap, but so far it hasn't been a problem as long as I'm mindful when re-orienting my bike at a stop or something. Granted, I changed quite a bit from what came stock on the bike and in hindsight, going custom from the start would have been a better option and I'd likely have a bike I'm happier with, but I was brand new to biking and thought going custom would be ridiculous. Still, while I'm happy with this semi-step through frame and it's easier for me to ride this bike than my first one, I wish my saddle could be higher so I'd have some more clearance for a bigger saddlebag. The step through frame eliminates frame bags and makes using the water bottle cage difficult.
Canyon makes road bikes with 650b wheels, but you'd have to order direct from them to try the bike.
