IMO, a small electric bike, such as my
Zero DS ZF 6.5, would be best for a RV use for several reasons.
1. No noise. It won't bother anybody in a RV park, not even at night.
2. No clutch (helpful to get up on the hitch and it's easy to have it go very slow). There is so much torque on these E-Bikes that there is no need for a transmission and clutch.
3. There is always a way to charge it from a RV. Generator or the AC from when the RV is plugged in.
4. Usually, you only need a short range from your RV and this cycle is good for around 70 miles in slow city traffic on full charge. Half that distance if on the freeway.
5. The optional saddle bags and travel trunk are very easy to remove and store in the RV when the bike is on the hitch.
6. The bike has the torque for two people (78 ft-lbs of torque). It does have passenger foot pegs. Comfort is NOT much of an issue on such a short range bike.
With the saddlebags, travel trunk, other storage spaces in the bike (for not having as much room taken by batteries) and a backpack, there is a lot of storage space on these E-bikes.
But if you want a cycle that is best for a camping trip (when not being towed on the RV) you need two different motorcycles.
I am into backpacking and backpacking stuff is also great for motorcycles as everything is rather light and small. But what is best to be towed on your RV is a lot different than the type of bike I would want to take on a long trip by itself.
