These bikes were a great way to get around the island! The batteries last a long time and have plenty of power! My family and I rented the bikes for 4 hours and a few of us only had our battery go down 1 bar out of 5, and those people didn't even pedal the whole 4 hours. These bikes were easy enough to ride for my parents who haven't road bikes in ~30 years. The fat wheels look scary, but add a lot of stability, especially around sand. I kind of want to buy an electric assist bike now.
