While I love mopeds and bought a 1980 vespa grande in college, I would not advise this.

As the song goes, "mopeds are always broke, but they easy to fix".

A moped WILL break down on you and be underpowered. My grande with a 70cc kit, performance variator and multiple breakdowns tops out around 41mph.

If you are not interested in repairing bikes or paying for their repair (if even possible in your city), avoid mopeds.

I'd recommend a 125cc+ scooter though. Reliability, fuel efficiency, and a bit more power which can increase safety. They also have more storage.

Don't forget to add in the fixed cost of gear!
