Looking for rack feedback. I need to hold 4 e-bikes and is easy enough that my wife can load when I am not around. They are mountain type e-bikes and weigh roughly 50-60 pounds. Came upon RevlRax, they look brand new. It’s a vertical style hitch rack. Anyone know anything? I like the idea of motorization to be able to lift the bikes and ratcheting straps to secure them. Any other thoughts on best way to transport 4 e-bikes?
