Okay so Indiana does give out titles BUT its not required to ride a moped.
Here is what I came across about Indiana moped law:
What's a moped?
Under Indiana law, a moped (or motorized bike) is defined as a two- or three-wheeled vehicle with a cylinder capacity of 50 cubic centimeters or less, a horsepower rating of less than 2.0, and an automatic transmission.
If a vehicle exceeds these limits, it's considered to be a motor vehicle, and its operators must follow the licensing, titling, and registration rules for a motor vehicle. See our sections on these areas for more information.
Moped riders must be at least 15 years old, and have a valid driver's license or state ID card with them when riding. Additionally, mopeds may not be driven on an interstate highway (why would you?), or over 25 mph. And, mopeds may not be driven on sidewalks.
Riders under 18 must be equipped with a helmet and something to protect their vision, such as goggles, glasses, or a transparent face shield.
So.... any thoughts? Should I just go to the DMV and try it out?
