When you purchase a Minutes Bundle Pass, you'll receive a set amount of minutes that you can use for rides within a specific number of days. Once you reach the specific number of days or you've used up all your minutes, whichever comes first, you will be charged at the pay per ride rate, or you can simply purchase the pass again to keep unlocking the benefits.
Remember, there's no auto-renewal for Minutes Bundle Pass, so you'll need to re-purchase the pass if you want to continue enjoying the benefits.
