Well, my part in aerodynamics is that I took off my rear rack, both fenders on both wheels, I keep the handlebars permanently done, and I recently installed some L bar ends I bought from walmart which help alot.
Yes, my cadence is between 90 and 110 depending on the wind, and how hungry I am. I've tested my cadence and I do get up to 20 mph at 100 rpm, the tires I have are both 20 x 1.75 and I keep them at 60 psi. Half a year ago I replaced my rear rim with bmx one from my Local bike shop which was heavier but stronger than previous one.
I really want to get work in a hour, but I keep maxing out on 48x13. I can cruise that at 17 mph easily, but 48x11 I can't cruise about 14, and the wind destroys me on that cog.
If that's your speed on that folder, it just proves my suspicion that equipment plays no more than a tangential role.
That's quick.
18 used to be my top speed, and anything over 13 mph was so tiring, I don't know why but I'd so much faster now and 15 mph is like walking through a park.
I've been trying to figure out how to maximize this folder's performance and I think most like its the weight.
This is what it looks like now
And what it original looks like.
