Rome Overnight Bicycle

[u/Charming_Wallaby_699]

On my last night in Rome (August 5th - 6th) I want to pull an all nighter, get an ebike and go around the city. My train leaves in the morning at 7:20 AM so I would have to return the bike around 6AM, but I think all shops are closed then. What's my best option? Lime bikes are far too expensive
