Thank you all, too!
I really love my bike, but I don't wanna show it alone, I like to present it in some beautiful local areas where I live.
By the way, I am very very conform with my little Garmin Edge 810 GPS which I fit to my bike- even It is a regular bicycle GPS. I have no external current wiring for it, the manual says it can up to 15 hours without using the display illumination. Also, it records my activities so I can later see where I has been, my speeds, the local height and temperature

.
The mount is from Garmin, but an extra supply.
Today I let me lead to an amazing sea.
