I just wanted to post something here in case anyone is planning to bring a bicycle to or riding to Martha's Vineyard in the future.
About a month ago the wife and I decided to go to MV camping and load up our small car with gear and strap the bikes on. Since I didn't realise how far in advance you need to reserve a ferry slot, we couldn't get our car over. The camping trip then turned into finding a cheap hotel. (we are not bike camping people).
If you drive down to Woods Hole, Massachusetts with your bikes, you will need to park at the Palmer Lot of the Steamship Authority. There they have a "bike" bus. This bus is basically an old school bus with seats down one side and hooks/bungies on the other to hang your bike up. You bring everything with you also. This bus will drop you off at the ferry terminal for no charge (included in parking fee).
The cost of walking on the ferry with your bike is $9 total ($6 you + $3 bike). The ferry we went on was an open one and the bikes are laid against each other luckily by an employee who appeared to care for the positioning of the pedals and such.
When we arrived to MV it was easy....grab your bike and walk off to hotel. (we stayed in Vineyard Haven (TISBURY) so the walk was quick). If you are heading to other parts of the island, the VTA (Vineyard Transit Authority) busses have bike racks on the front (2 bikes max) and appear to be very secure. These busses are located directly in front on ferry landing.
The island has numerous bike paths to Aquinnah (Gay Head),Edgertown, South Beach, and people do appreciate it if you are on them for the roads are quite narrow throughout the island. While we were on a bus heading for the Gay Head lighthouse we got stuck behind a group of about 15 bicyclists heading the same way on a narrow very curvey road. It frustrates the bus drivers and passengers.
We did not bike as much as I though we would due to my wife not being an avid rider but we were able to ride one day to the Felix Neck wildlife sanctuary. One note: when you get there the entrance is a dirt road with a sign directing bikes to take a path next to the road through a trail in the woods. This trail is not good for straight road bikes....flat yes but numerous sandy patches and roots....and Don't stop...mosquitos don't waste any time.BRING BUGSPRAY WITH YOU!!.
Just about everywhere there are bike racks to lock to. We locked ours and had no feelings of insecurity leaving them there. Hotel said no one has ever stole bikes from there place.
