Sweden

Mopeds are available in two classes. Class 1 (also known as EU moped as it was introduced to comply with European Union rules) is a moped designed for a maximum speed of 45 km/h powered by an engine of 50 cc or, if it has an electric motor, has a maximum power of 4 kW. A driver's licence type A (motorcycle) or B (car), a driving licence for tractor or a class 1 moped licence (when you're 15 years old) is required to ride a class 1 moped. In traffic class 1 mopeds are regarded as motorcycles (but may not be driven on freeways or motorroads) and has to be registered and have a licence plate. They are however tax-free. Class 2 is a moped designed for a top speed of 25 km/h and has an engine with maximum 1 kW. No licence is required, but the driver has to be above 15 years and wear a helmet. In traffic they are regarded as bicycles unless there are signs explicitly forbidding mopeds. Mopeds registered before June 17, 2003 are called legacy mopeds and they are subject to the same rules as class 2 mopeds, but may have a top speed of 30 km/h.

Switzerland

A moped is considered to be a two-wheeled vehicle that has pedals, a motor, which is less than 50 cc and a top speed of 40 km/h. The moped must be registered and must have a number plate with a sticker for that year indicating that the vehicle is road taxed and insured. The government handles insurance. These vehicles are regarded bicycles in traffic and are therefore not allowed on motorways. To drive this vehicle one must have a Category M licence (which comes with every car and motorbike licence) as well as a motorcycle helmet. A Category M licence is obtainable at the age of 14. At the age of 16 one can obtain an A1 licence to drive a 50 cc motorcycle, which does not conform, to the 40 km/h limit.

Thailand

The regulation of motorcycles in the city is different from the regulation for home use. Motorcycles in the city must have paid road tax and have a valid license plate number. However for the motorcycle for home use, a motorcycle might not need to be registered if so the motorcycle will only be able to be used in farms or a small town. Wearing helmet is a must when riding on a major road and in the city. There is no limit of maximum pillion riders on the bikes even in the city.

United Kingdom

The term moped describes any low-powered motor driven cycle with an engine capacity of less than 50 cc and a maximum design speed of no more than 30 mph. If used before 1 August 1977 it must be moveable by pedals and although it must be 50 cc or below, it does not have to conform to the 30mph speed restriction. (This is where the original name 'moped' is derived - Mo = motor, Ped = pedals). A provisional licence, full motorcycle or car licence is needed to operate a moped. An additional Compulsory Basic Training certificate is also required to ride a moped on public roads, except for anyone who obtained their full car driving licence or motorcycle licence before 1 February 2001. A provisional moped licence may be obtained at the age of 16, whereas standard car and motorcycles licences are only available at the age of 17. Provisional licences require learner plates and expire after two years if the licence holder has not upgraded their licence. Mopeds are subject to all of the same traffic laws as other vehicles. All motorised cycles/motorcycles/mopeds under 50 cc are excluded from using UK motorways.

United States

Legal terms and definitions of low-powered cycles vary from state to state and may or may not include "Moped," "Motorcycle," "Motorized Bicycle," "Motor scooter," "Goped," "Motor-Driven Cycle," and or others. A moped's speed generally may not exceed 30 mph (48 km/h) on level ground, even if it is capable of going faster. In a few states this number is 20 or 25 mph (32 or 40 km/h), and in most states, the maximum engine capacity is 50 cc. However, Kansas ("Motorized Bicycle" K.S.A. 8-126, 8-1439a) allows up to 130 cc[11]. Some states require pedals, while others do not. Virginia allows mopeds to operate at up to 35 mph.

Vietnam

Mopeds can be seen everywhere. In the main cities of Hanoi and Ho Chi Minh City, mopeds are by far the preferred method of transport, due to the narrow nature of many of the streets, and the sheer volume of vehicles on them. In fact, many of the shops along these streets are designed so that these mopeds can be parked inside of the shop.
