Hi, I am new to this forum and I haven't ride a bike for many years. I want to order a folding bike as my first bike and learn to commute around NYC this summer. I do fear about riding with the cars but it is my goal to get over that fear. I am currently looking at the Citizen Tokyo and Citizen Miami folding bikes. I have been on Google for a bit searching hints of if I should get the 16" Tokyo or the 20" Miami. Do anyone know a good comparison between a 16" and a 20" folding bikes? I want to bike around the city and also use it to bike to school in fall. I am 5'2 and petite, so I'm a bit leaning towards the Tokyo (it also have more color choices and $30 cheapier). But my brother recommend me the 20" so he can use it too, and one of my friend said it'll be faster. So I am really not sure. Can anyone help me out a bit? Thanks in advance!
