Bikes, in general, are stolen often, but an electric bike is the crown jewel for a thief. With e-bikes normally, a more significant investment here is some of these bicycle theft prevention ideas to consider. To protect your e-bike investment, consider using a U-lock in combination with a cable lock or bike lock alarm. You could also take the bike inside a building with you or use a mobile bike storage locker for storing your e-bike.
