“Great 4 hour trip idea” We found these bikes in Lahaina, Maui. They have the battery packs to assist you with peddling and go about 20 mph. We started in Kahana went up the mountain to the coffee fields they had wonderful views of Ka'anapali. Went down the mountain to the old Sugar train tracks and went off road until the Hotel row entrance cut behind Hyatt to the beach path to Lahaina. Onto Front Street to Aloha Mixed Plate for some lunch and back to Kahana. Took about 3 hours and still had full batteries. Probably could have let the battery power drive us the whole way but that's not exercise. Give it a try ask for Lee the owner he will be glad to help.
