Island Time's E-bikes made seeing all the carriage roads in Acadia not only possible but enjoyable. There is no way we could have managed even 5 miles with the hills on a regular bike, but with the e-bike assist, we covered 30 miles, with lots of hills, and had plenty of battery life left. It certainly wasn't cheap, but we all agree it was money well spent. (especially when we passed very fit folks on regular bikes as we were going steeply uphill!) Bikes were in good repair, and they also provided clean helmets, maps, water bottle holders and insulated containers that held our lunches.
