@1234 I think yours is a good business idea if you can implement it properly to give maximum cycling satisfaction.
Forgive me if I missed it with the many ot posts, but what Greek island is it?
From my experience riding with female only and mixed groups alike, here is what I think would make your idea a success.
First, I would concentrate on attracting the intermediate riders that may want to incorporate cycling for fun in their holidays while exploring new places.
The more experienced, the pro or semi pro will already have their training plans, the fast amateurs mostly go to Spain, France or Italy to tackle well known hills for a challenge, I may be wrong, but they would not come to you.
Your ride leaders are crucial, they will make the rides a holiday to remember, to tell your friends about.
Be very clear in what rides you're offering but be also prepared to hear moaning about the routes after, sometimes people overestimate their capabilities, not much you can do about this.
You will need to have lots of bikes, or a nearby rental place that you could strike a deal with.
Me, I would be mostly impressed by little touches like my provided bike to have a rack, a pannier with pump, spare inner, tyre levers and multi tool for a deposit, free water bottle in my room on arrival.
In England Breeze rides are popular, while in Scotland we have the Belles on Bikes: each major city.region have their own groups with online pages: get posting about your holidays!
Women only activities are not normally my cup of tea, but this one sounds good, I could see myself going on one
