The decision to bring your own bike (if you have one) or simply rent a good one, is a very personal one and can be budget based or have many other reasons.
Your own bike is what you know best and are familiar with. On the other hand the normal level of the rent out bikes nowadays is so very good and relatively cheap, that this is certainly an option to consider.
The agency will also know the bikes well, will be able to offer spares and repair service, which can proof to be a big advantage, for sure when your own bike is a bit exotic.
In case where the destination is far away, and maybe reached by plane mainly renting is by far the best option.
Quite a few aspect to consider and we will bring more info on that lateron.
