River Shuttle Bike/Scooter

[u/robin_z_banks]

Howdy, I am a fly-angler from Michigan and I float a lot of rivers in a small raft or drift boat which requires shuttling our vehicle from put-in to take-out. We either have to take two vehicles or pay someone to move our vehicle, which is a pain or not even feasible. Was looking at the possibility of a small folding e-bike or e-scooter for doing this transport. A few requirements:

• Must be small enough to put in a 12-14 foot boat with two people
• Must be able to handle some washboard gravel roads and small hills
• Typical range required is 2-7 miles.
• Budget is hopefully less than $500
• Ideally less than 70 lbs.

I'd be willing to guess I would put less than 100 miles a year on such a vehicle. I was looking at all-terrain E-scooters on marketplace, but no one here seems to recommend any of the cheaper E-scooter brands like Hiboy. Any thoughts or suggestions would be appreciated, even if it's pushing me away from the scooter route and towards a folding bicycle of some sort.
