Operating A Motorized Bicycle
Indiana law defines a vehicle as a motorized bicycle or moped if it meets all of the following specifications:
-It has two or three wheels; and
-It is propelled by an engine of no more than two horsepower; and
-It has a cylinder capacity of less than 50 cubic centimeters; and
-It has an automatic transmission; and
It has a maximum design speed of 25 miles per hour.
Vehicles with engines exceeding these limits are defined as motorcycles and the rider must hold a motorcycle endorsement, license, or permit. To operate a motorized bicycle, you must be at least 15 years old and carry a valid Indiana driver's license or identification card. If you are younger than 18 years of age, you must wear protective headgear and protective glasses, goggles, or a transparent face shield.
Motorized bicycles may not be operated on interstate highways or at a speed faster than 25 miles per hour.
