Our visit to the Cavern e-bike tour was terrible. The other activities looked fun, but with the high prices, only could choose one activity - $39.99 for e-bikes. The e-bike tour includes a motorized bike you ride throughout the cavern with a tour guide. Really the entire tour was bad, realize sometimes there can be bad days. However, the motorized bike stop running about 10 minutes into the 1 tour. The guide tried to reset it about 3 times, he gave up, and just said.... "the bikes tend to this at the end of the day". Also, the danger it posed when about to hit the hill and all the sudden you start falling back and peddling so others do not run into you and you don't fall. Not to mention, another guest had the exact same issue with their bike and had to peddle the majority of the time as well. After the tour we went to speak to management, only to be informed there was no manager on site. Huh? After pressing Cindy further she said, we have and Assistant Manager, Scott. Well Scott told us he could not address the issue and call on Monday to talk to Jeremy the General Manager. All I can say is ......WOW! not looking for a free ride, but maybe some consolation to the fact that I paid $39.99 for a motorized bike tour and did not get what I paid for......thought the representatives of Mega Caverns would show a better representation of Kentucky. Being a local, was disappointed as our whole tour of people were guest visiting from out of state, and this is the experience they have.
