Moped

technology Maturity 5-7 Next article →

A moped is a small, inexpensive type of motorized vehicle. It is often categorized as a lightweight motorcycle.

These vehicles are popular because they usually have less strict licensing requirements than cars. This means they are accessible to many people. Historically, the term referred specifically to a motorcycle equipped with bicycle pedals. Today, mopeds are generally defined by their low engine power. Most common models have an engine capacity of 50 cc or less. This measurement, cubic centimeters, describes the volume inside the engine cylinders.

The way a moped functions depends on its specific mechanical design. Many early versions were simply bicycles with a helper motor attached.

For example, the VéloSoleX brand used a roller that sat against the front tire to provide drive. Another design, known in the UK as the Cyclemaster, used a complete powered rear wheel. This unit was designed to be swapped in for a standard bicycle wheel. Some mopeds use a step-through frame for easy mounting. Other models use a motorcycle-style backbone frame with a raised fuel tank.

Many mopeds still include a crankset and pedals. These allow the rider to provide light pedal assistance (LPA) when climbing hills.

There are several distinct types of low-powered two-wheelers. Some machines are derived directly from motorcycles but have smaller engines. Others, like the Czech-made Jawa, follow this motorcycle-based design. A different category includes autocycles, which are slightly larger machines with engines. In some modern jurisdictions, bicycles with helper motors are called motorized bicycles.

However, other regions might classify these same machines as mopeds. This can sometimes cause confusion regarding legal definitions. In certain countries, even three-wheeled vehicles or microcars are classified as mopeds. For instance, France and Belgium categorize microcars as light quadricycles or mopeds.

The history of the moped is tied to the evolution of motorized transport. Early motorcycles, such as a 1912 Douglas, sometimes featured pedals. As engines and clutches improved by 1918, pedals became obsolete on most motorcycles. However, pedals remained a valuable feature on mopeds until the 1990s. The word "moped" itself has a specific origin. It was coined in 1952 by a Swedish journalist named Harald Nielsen.

He created a portmanteau from the Swedish words for "motor" and "pedals." This name accurately described the "pedal cycle with engine and pedals" used at the time.

Regulations for mopeds vary significantly across the globe. The Vienna Convention on Road Traffic defines a moped as a two- or three-wheeled vehicle with an engine not exceeding 50 cc.

In the European Union, riders typically use an AM driver's license. This license covers mopeds with a maximum speed of 45 km/h. Rules in Austria require riders to be at least 15 years old. In Canada, laws differ by province. In British Columbia, a moped is a limited-speed motorcycle that weighs no more than 55 kg without fuel. In Ontario, a moped is specifically a motor-assisted bicycle with a maximum speed of 20 km/h.

Environmental impact is another important aspect of moped technology. Mopeds can be very efficient, achieving fuel economy of over 200 km/l. However, their emissions vary based on engine type. Studies show that two-stroke 50 cc mopeds can emit ten to thirty times more hydrocarbons and particulates than Euro 3 automobile standards.

Four-stroke mopeds are cleaner, emitting three to eight times the hydrocarbons of those standards. In the United States, the EPA allows certain mopeds to emit higher levels of nitrogen oxides (NOx) and carbon monoxide (CO) than median automobile regulations. A higher density of these vehicles can also impact air quality in urban areas.

Safety is a critical consideration for all moped riders. Because mopeds travel at lower speeds, they face unique risks. One major danger is that other traffic may not notice them. Drivers might see a moped and assume it is harmless, then accidentally pull into its path.

This is especially dangerous on high-speed roads. Riders should wear bright clothes and reflective fittings to increase visibility. Some riders illegally "tune" their engines to reach higher speeds. A survey in Finland found that 80% of vocational students and 70% of gymnasium students had tuned mopeds. These tuned vehicles can reach 72 km/h, which is much higher than the legal 45 km/h limit. Using a vehicle not designed for high speeds is much less safe than using a purpose-built motorcycle.
