I’d say, the most important factor if you plan to learn to ride it, is that it’s the right size for you.
Your inseam length can determine that.
There’s a formula for figuring out what size wheel is right for you specifically.
I don’t remember what that is, so I suggest you slow your roll, and do some research before you buy.
There’s a book sold in the bookstore here on the Cabe, that is called, the Antique Bicycle by the author, Adams.
It is the definitive bible on the subject, and can tell you everything you need to know, and what to look for.
I highly recommend you check it out.
It will be the best investment you make in your quest to acquire a high wheel bicycle.
Good luck, and enjoy the ride!
