Wife and I are coming to Oz next July for a holiday and we thought it might be a nice idea to hire a couple of bikes. Ideally we would like to hire in Sydney then travel up the coast (a trip I did 27 years ago - yikes!!) stoping off to see some friends in Byron Bay then dropping the bikes off in Brisbane.
Is there a firm that accommodates this without charging shipping costs back to Sydney?

We will be visiting people in Victoria, Sydney, Byron Bay and Brisbane. The other alternative is to just rent in Sydney or Brisbane (I expect the weather to be too much of a gamble further south). Will the Blue mountains be a pleasure to visit this time of year or are we better to head north?

Many thanks
