Interesting! Mind posting a few pics? Are you using on the motorhome or back of toad? Thinking about a solid option for two Lectric bikes for next season... but we will most likely be pulling the Jeep too. Suggestions welcome!
1UP-USA HAS A SUPER DUTY HITCH MOUNT BIKE RACK THAT IS ADAPTABLE TO A FAT TIRE BIKE TOO. We have 2 high end e-bikes and 2 fat tire bike that we travel with frequently. This is a solid rack and easy to use. Their customer service is awesome as well. The super duty comes in black or bare aluminum. 950 for a 2 bike rack and is expandable. Each slot can hold a 100lb bike.
For those interested in carrying an E-Trike I found that 2 Lectric E-Trikes folded will fit very well on a Mockins 72 x 36 cargo carrier. Tomorrow I will install the tail lights that come with the carrier kit.
