The minimum age to drive a motorcycle depends on the country and the type of motorcycle licence:

• In the UK, you can ride a moped (up to 50cc) at age 16 after completing compulsory basic training (CBT). For a light motorcycle (up to 125cc), the minimum age is 17 with CBT and passing theory and practical tests. For larger motorcycles, the minimum age is 24 for direct access or 21 if progressing from an A2 licence after two years

• In Germany, the minimum age for a full motorcycle licence (Class A) is 24 years for direct access or 20 if you have held an A2 licence for two years. For smaller motorcycles (up to 125cc), the minimum age is 16

• In the European Union, minimum ages vary by licence category:
  • AM (mopeds): 14 to 18 years depending on the country
  • A1 (light motorcycles up to 125cc): 16 or 17 years
  • A2 (medium motorcycles): 18 years
  • A (unrestricted motorcycles): usually 20 to 24 years, sometimes with progressive access requiring prior experience on A2

• In the United States, the minimum age varies by state, typically ranging from 14 to 16 years for learner permits and 16 to 18 for full motorcycle licences.

In summary, you generally need to be at least 16 years old to ride a moped or small motorcycle with restrictions, and 18 to 24 years old for unrestricted motorcycle licences, depending on the country and licence type.
