- A cycle with pedals to permit propulsion by human power or without pedals and with a motor of not more that 50ccs or 2bhp.
- Cannot go over 30mph on level ground.
- Operated by an automatic transmission without clutching or shifting after the drive system is engaged.
To operate a motorized bicycle in South Carolina you need a valid drivers license. If you are at least 14 years old you can apply for a moped permit.
