ISO E-mtb in August

My parents will be visiting in August and I'd like to take them out on some easy loops. They're not used to the elevation gain and, sadly, Revolution told me they wouldn't have e-bikes available to rent this summer. I'm looking out to see if anyone would be willing to rent their small/medium e-bikes for a day or two in the second half of August. I'm also open to suggestions on the closest places that would rent!

Gericks just posted they have some for rent. 

"Summer is finally here! What better way to spend an afternoon than on an E-Bike with your friends!
