A motorized bicycle is considered a moped under Kansas state law. A moped is defined as a vehicle that has:
- 2 to 3 wheels.
- an automatic transmission.
- an engine up to 3.5hp.
- an engine no bigger than 130cc.
- a top speed of no more than 30mph.
You must have a valid drivers license to operate a motorized bicycle in Kansas. Another option is to get a special moped license which requires applicants to pass a written and visual test.
A motorized bicycle must be registered to ride it on public roads in Kansas as long as it doesn't exceed the specifications outlined above.
If the vehicle exceeds the limits of a moped then it must be registered as a motorcycle.
