Given enough Watts, all mountains become shallow. As I live on the french riviera, the obvious place to test an ebike ist the Col de la Madonne. It is pretty famous among road cyclists because it was the favourite test drive for Lance Armstrong.
And guys, it is beautiful. Say about Lance what you want, be he knew the good places.
This is what it looks like:
All the way up you have a stunning view over the mediterranean and very little road traffic. The glamour of Monaco is at your feet, the blue of the sky melts into the blue of the sea...
The picture below is taken at the top of the pass, a selfie taken the old fashioned way with a timer. I think I need to train this a bit more.
KERS - Kinetic Energy Recovery System
Below is the log of the trip from Nice to Italy via the Col de la Madonne. In true geek fashion the controller is logging all the data. Display in the chart is:
- blue: speed in km/h
- gray: altitude profile in m
- red: ampere of the motor @ 48V
- green: Kinetic Energy Recovery System = recharge the battery
The green part is actually the cool part, the controller can does regenerative braking, in Formula 1 better known as KERS.
Thus doing the long descent is the ultimate stress test for the controller. PASS!
