At last we can refer you to a bike (and kayak) hire business in our area so if you're looking for a bike or some bikes to hire for a short ride or for several days, contact Region X.
There's another, newer, bike hire business in Narooma. We don't have a link for you but we do have their phone number: 0403 157 290. You'll find them a little off the highway in Narooma: heading south up the hill after the flat. turn left at the clocktower and heading down the hill a hundred metres or so you'll see them on the right (it's a residence rather than a commercial property but does have the hire signage up).
