At a staffed OV-fiets rental location, such as a guarded storage facility, you can return a rented OV-fiets to the attendant during opening hours. If you return after closing time, please place the key in the dropbox. The dropbox is NS blue and around the size of a sheet of paper. Simply open the box and insert your key..
Please note: You will continue to pay for the OV-fiets rental until the bicycle has been scanned. You are liable for any risks resulting from parking the OV-fiets outside the storage facility.
