Or maybe check the accuracy of your speedometer.
Exhilaration is a powerful force, beyond all logic.
Not really, It comes out to roughly 56if and 75if for 1st and 2nd. Maybe you thought it was a single speed?
It rolls easily at 25 in 2nd with normal cadence. Getting it up to 30+ gets it spinning pretty fast.
You can see my speedo on the handlebars. its a cheap XOSS but its wireless GPS so I don't think there is much wiggle room there. You can also see the Zefal strapless toe clips. Those help a lot with changing gears and zipping around.
I built it to do 25 easily because that's as fast as I should be going with one arm.
I just meander and clip around on flat terrain here in Tucson
