If you are a serious (and I do mean serious) cyclist and you are looking for an alternative biking excursion besides going down the mountain, I highly recommend "Go Cycling Maui". I can not stress enough, that this is not for amateurs nor for the faint of heart. My husband bikes and wanted a different experience and I found these guys. They are GREAT. They hook you up with everything you need. They do recommend that you bring your own pedals (if you have them) and bike shoes. My husband's bike was a titanium framed bike just out of the box. They go in groups of about 7 and take different routes throughout the island. The day my husband went, they went to an area referred to as "Up Country" and he estimates that it was maybe around 45 miles. I didn't think it could be done, but they kicked his behind and he loved every mile of it. He found that even if you just want to rent a bike and trek out on your own, Maui seemed to be very bike friendly. Thought I would pass this on to anyone who was interested.
