I too was out today as it was quite warm for Dec. I did another little test on the 45 Km/h setting. I have a 2-legged stand so put the bike up with the rear wheel off the ground, set the MAX PAS to 45, and turned the pedals by hand. The speedometer read a max of 42 Km/h, pretty much the same as I saw when riding on flat ground. Maybe it reached the max RPM for the motor? -- who knows? In any case, I'm not concerned as I have that setting at 32 Km/h.
