Schönes Design und macht was er soll. Allerdings lässt sich ein alter Kilometerstand, z.B. nach einem Batteriewechsel, nur mit einer speziellen Dockingstation eingeben. Das sollte in der Produktbeschreibung erwähnt werden.

Nutze mittlerweile 2 dieser Tachos. Tun genau das, was sie sollen: Anzeige von Momentangeschwindigkeit, zurückgelegte Strecke und Fahrzeit. Das ganze bei schlichtem Design, gut ablesbarem Display und praktischer Ein-Tasten-Bedienung. Wie bereits in einer anderen Bewertung erwähnt fehlt leider eine Uhr und auch die Durchschnittsgeschwindigkeit lässt sich nicht anzeigen.

Für den Preis sehr gut. Anzeige gut ablesbar. Design schön schlicht und sauber verarbeitet. Eine Uhr fehlt zwar. Aber trotzdem top für den Preis.
