By Joan P. The 7.5MPH which is pretty fastReview for SWAGBOARD VIBE Bluetooth Hoverboard, T580This Hoverboard seems to be good quality. My 6 year old son picked it down really quick and can ride it very easily. It’s pretty heavy which is good. It’s the power button and the charging port using one side. The charging cord has lights to inform you when it is charged.Posted by Joan P.
