I'm a 5'1" woman looking to purchase a classic bike for transport/leisure. Unfortunately here in the London and in neighbouring cities/countries, I can only find 17"+ frames available. Most sizing charts recommend 15" for me.
Perhaps I have more flexibility given that I'm not properly sizing for a road/mountain bike or anything. Would a 17" frame be ok? I don't want to strain my knees or risk back issues.
Total novice at this, but I also measured my inseam in two different ways. 28.5" maximum if I want 1 inch of room while standing over the seat. 23" if I use the book method and allow 5 inches of room while standing over the seat. Seems like a lot of 17" bikes online lower down to 26" inseam height.
