I have cycled through Maine twice and was not impressed at either times. The roads were too busy and New England charm was just not there.
A couple of things that will make it worth the trip:
1. Cycle through Acadia
2. Continue along the coast into NH or inland into the White Mountains.
Here are a few resources for routes:
