Basically, you would remove the "Active reservation" field from the "Bookings"-tab.
It contains the following information which needs to be integrated into the rent-popup:
Station name
This is basically covered by the rent-popup: When open, you either see a station name in the "Cancel booking"-button, or nothing, which means that the booking is for this particular station.
However, this might be a bit unclear when you're actually not remembering which station you booked. The information should be integrated into the map (without opening a station) e.g. by changing the station icon to, let's say, a gear wheel containing an 'R' for "reservation".
The reserved slot's number
This is already fully integrated into the rent-popup: When selecting or booking a bike, the slot gets pre-selected (and you can choose another bike if you want to).
The time until the booking is valid
This could be integrated directly into the rent-popup as an information below the cancellation button (something like "auto-cancelling in ..."). With more effort, the "reserved logo" described above could carry this information in its color (changing from green to red when the time runs out).
