I was riding on a paved bike trail today with my wife and I just had to know "what'l she do ?"
On the tallest chain ring, and smallest rear gear, I hit 18.6 MPH. I think with an easier gearing with faster cadence, I could go faster.
BTW my wife and I were the Only people on the trail, and this was with platform pedals.
So how fast have you taken your Clyde Ride?
