Clearly and absolutely enough for the amateur driver

I bought this speedometer to get an overview of the cycling holiday. On my bike it was his turn never, because when I unpacked him he has my girlfriend like so much that they really wanted him.
Now it's his turn to their bike.

The installation is very simple and requires no additional tools. It is operated with small button batteries, one of which is for the operation is not on this list. So far it reaches two years.

The display is large and therefore easy to read and well-switch operation with simple buttons on various displays.

For everyday I think it takes no more than what provides the speedometer here.

For the price an absolute recommendation. When I got my new bike in the spring, I'm going to buy the speedometer too.
