The 557 is a premium e-scooter with many innovative components that add to its beauty and overall performance. It has been carefully designed to offer an unparalleled riding experience with impressive functionalities. Despite this high price, the AER is a game-changer. As an e-bike and e-scooter crossbreed, you get the best of both worlds. Most impressive are the comfortable 20-inch tyres, the detachable display with a built-in GPS and immobiliser, and the ergonomic bamboo deck and hydroformed aluminium frame designed to flex and absorb vibrations. So, the AER 557 is not just beautiful to look at; it has the performance and value-for-money to boot. The 557 is truly the best e scooter we’ve had the pleasure of reviewing in a while.
