Re: Any motorized bike stuff in Hawaii?
There are no motorized bike vendors on Oahu that I know of.
MB's are the "black sheep" of the family. the LBS will not service you unless you remove your motorized gear before bringing the bike in.
The Whizzer is the exception. My LBS owner reluctantly agreed to service my bike, but said it would take a while.
The few motorized bicycle riders here buy on the Internet.
