How do I transport an eBike on a car?

Use a hitch-mounted eBike rack rated for the weight (most eBikes weigh 45-70 lbs; many standard racks max out at 35-40 lbs per bike). Trunk-mount racks are generally insufficient for eBike weights. Remove the battery before loading if possible to reduce weight and protect it. The Kuat NV 2.0 and Thule T2 Pro XT are popular hitch racks built for eBike weights.
