Overview
Vivi's electric mountain bike pairs a 500W motor, listed as peak 700 to 750W, with a 48V 10.4AH battery on a 27.5 inch frame, rated for up to 50 miles and offering 21 speeds across 5 ride modes. It carries SGS certification to UL2849.
The bike ships about 90 percent assembled, and most reviewers describe a smooth setup and reliable ride, including one owner past 900 miles with no mechanical issues. A handful of units arrived with a bent front disc rotor or a bulge in the rear wheel, and getting through to customer support by phone was a recurring frustration, with calls routed to voicemail during listed business hours.
