Ihr zuverlässiger DiebstahlschutzAuf diese Weise fährt Ihr Egret E-Scooter nicht mit jedem: Das 2-in-1-E-Scooter-Schloss, bestehend aus einem nachrüstbaren Rahmenschloss für das Lenkrohr und einem flexiblen Kettenschloss, ist die perfekte Diebstahlsicherung für alle Egret-Modelle ohne serienmäßig integriertes Rahmenschloss.Das starke und flexible Kettenschloss aus gehärtetem Stahl gibt Dieben keine Chance. Mit einer Länge von 120 cm ist für das Kettenschloss kein Abstand mehr zu weit oder fester Gegenstand zu breit. So findest du immer eine passende Gelegenheit, deinen Egret anzuschließen und gegen Wegtragen zu sichern. Während der Fahrt kannst du das Schloss unkompliziert an den Transporthaken an der Lenkstange hängen, ohne dass es dir im Weg ist.So funktioniert’s: Schlinge das Kettenschloss um einen festen Gegenstand, z. B. einen Fahrradständer oder einen Laternenpfahl, und ziehe den Bolzen durch die Öse am anderen Kettenende. Führe dann den Metallbolzen in die Öffnung des Rahmenschlosses. Sobald du den Schlüssel abgezogen hast, ist dein E-Scooter sicher abgestellt.LieferumfangNachrüstbares Rahmenschloss, Kettenschloss, Transporthaken, 2x Schlüssel, Gummiunterlegplatten für unterschiedliche Lenkstangengrößen, Montageset• Länge 120 cm • Gewicht 1.200 g• Farbe SchwarzKompatibilitätEgret Ey! 1, Egret Ey! 2, Egret Ey! 3, Egret Ey! 6, Egret X core, Egret X prime, Egret X ultra

Lightweight bike helmet with rear & brake light as well as fall detection and SOS emergency call. Safety and riding enjoyment are inseparable on a bike. For many, it is the means of transport of our time and has become almost indispensable for everyday life in the city. With the LIVALL C20, there is now a companion that looks after its owners. The brake & rear light positioned high on the head increases the rider's visibility. Especially in heavy city traffic, you will be noticed much earlier than with a conventional rear light alone. The LIVALL C20 has a very special feature in this price range for all those who sometimes cycle alone. Motion sensors continuously monitor the position of the helmet and recognise when the helmet is subjected to strong forces, such as a fall. The helmet reports this to the LIVALL app, which in turn informs an emergency contact by text message. Like a little guardian angel that lives in the LIVALL C20. To ensure that it is always active when its owner is, the LIVALL C20 switches on automatically when the helmet is moved and deactivates itself after 5/10/20 or 30 minutes of inactivity.Sizes M (54-58) & L (57-61), colours white or black
