Service scooters, we're told (7)
I believe the answer is:
vespers
'service' is the definition.
(vespers is a kind of service)
'scooters we're told' is the wordplay.
'scooters' becomes 'vespas' (Vespa is an Italian scooter).
'we're told' shows a homophone (sound like).
'vespas' is a homophone of 'VESPERS'.
(Other definitions for vespers that I've seen before include "An hour of worship" , "Evensong - RC service" , "Evening prayers" , "Evening service" .)
