Please keep in mind, I haven't joined a cycling club myself yet BUT definitely should expect more than what you're getting. While $25/year isn't a huge amount of money, you're still paying to be a part of it.
A cycling club that I'll probably join next year (also $25/year) has a list on their website of all their rides, past and future with contact info, route info, etc. all with varying distances and paces. If possible I'd try looking for something like that to make sure they go on plenty of rides.
As someone else mentioned though, I'd imagine many clubs would be okay with you tagging along on a couple rides before deciding to pay the membership. Good luck, hope you find one that works for you.
