I'm having issues finding a bike rack (hitch) that will work with a Gazelle Ultimate C8 and C380 in the LOW-STEP configuration. Most all hitches support the bike using the upper or mid frame bars. With the LOW-STEP there is no connection point. It will be used with a 2022 Mercedes AMG 450 63S vehicle. I contacted Yakama and they said none of their hitches will work with these bikes (no frame bar and fenders). I have contacted Thule and waiting for a response. Any help would be appreciated.
