I searched the BF and came up with blanks.
Does anyone have data on Acceleration from standing still to let us say 22 MPH?

Why 22 MPH? I get unstable biking standing up at speed above that.
I used a Treck Hybrid for this today. Total weight with Treck stem mounted bag is 38#.
Tires 700 x 38.
On smooth limestone trail.
No wind.
0 to 22 MPH in 20 seconds. (I have not the slightest idea if that is good or bad) Perhaps I can do better.

You know that it is common to talk about cars accelerating from 0 to some speed, so why not for a bike?

I will test this soon with my Treck Madone. That should be interesting.
Jppe, are you there? I think you would know this kind of data.
