Maybe it's a Maine thing...but the man who taught us to run the e bikes was very rude! My sister in law was quite timid about riding one. She is very short & was worried about her feet being able to reach the ground. When she asked for a smaller bike, the operator said, "OK I will drive back & get a new one & see u in 3 hours!" It was said in a very mean non funny way. When she fell off & he was worried that she would damage the bike, then he allowed her to use the child's bike. I had an unusual seat that I was questioning him about and he said " Every ASS is different." He needs to go to a customer service school. Very rude & impatient.
If u can get past him the trails and bike ride were a thing of beauty.
Retrain the operator (is he the owner?) & have someone smile & patiently help the bike riders for the millionth time. That is your job!
