So this is my speed graph - so this is my approx 40km ride. The EVO easily clears around 18 to 25km/hr. It’s > 2 hours ride - some stops (traffic lights, drink stop, etc).
Throughout most of this ride - I am on top gear. I sometimes wished the EVO had a 4th gear 
But then that would make the hub difficult to use (?).
IMO - the 1st gear is not useful unless you are doing 45 degree incline hills!
How to read the graph:
X - axis is time (mins)
Y - axis is speed km/hr
