Electric two-wheelers have transformed the way people move in most Chinese cities. In just ten years, growth in electric two-wheelers&#;a category that includes vehicles ranging from electric bicycles to electric motorcycles&#;has substantially increased the total number of vehicles in China. Electric bike sales began modestly in the s and started to take off in , when 40,000 were sold. Since then, over 100 million have been sold and now more than 20 million are sold each year. Electric two wheelers, in short, represent the first mass-produced and mass-adopted alternative-fuel vehicles in the history of motorization.

For anyone interested in alternative fuel vehicles, the dramatic success of electric two-wheelers in China merits attention. How did this explosive growth occur? What have the results been? And what is the potential for electric two wheelers to spread elsewhere around the globe? In this article I examine these questions. Electric two-wheelers have filled an important and otherwise underserved niche in the China&#;s crowded transportation system. Electric two-wheelers can maneuver through congested streets. They can be charged from traditional wall outlets and often have a removable battery, allowing them to be charged indoors. And they have some of the lowest emissions of any type of motorized transportation. For residents of dense Chinese cities, electric two-wheelers provide a high level of door-to-door mobility at low cost.

Electric two-wheelers have filled an important and otherwise underserved niche in the China&#;s crowded transportation system.

But two-wheelers are not without their critics. Regulations on the production and operation of two-wheelers have been in place since , but these rules are only loosely followed. Two-wheelers are getting larger and faster, and as they get bigger, confusion about how to classify them increases. Are they motorcycles? Are they bikes? The increased speed and power of the two-wheelers also raises concerns about safety, and threatens to diminish some of their environmental benefits. The question of how clean two-wheelers are is also a complicated one, because while their tailpipe emissions are low, they nevertheless create emissions in the places where their electricity is generated.

Nor is it entirely clear whether two-wheelers will spread abroad. The popularity of electric two-wheelers in China owes in part to severe restrictions on some competing modes. Whether electric two wheelers would be as popular in the absence of such regulations is an open question.

The Rise of Electric Two-Wheelers

China&#;s electric two-wheeler growth has been spurred by two notable policies from the central government. First, in , the government designated certain electric two-wheelers as bicycles. To be considered a bicycle, an electric two-wheeler was required to have a bicycle-style design with functioning pedals, weigh less than 40kg, and have a maximum speed of 20km/h. This classification meant, among other things, that qualifying electric two-wheelers could travel in the bicycle right-of-way, that they did not require licensing and registration, and that users did not need a driver&#;s license. These advantages made motorized travel available to many people who would otherwise be unable to use it. TK Second, many cities severely restricted the ownership and use of gasoline motorcycles in their urban cores. In a nation with crowded roads and restrictions on gasoline motorcycles, it is perhaps not surprising that a low-cost vehicle that ran on electricity and could travel in bicycle rights-of-way became popular.

Early electric two-wheelers were electric bicycles, generally equipped with a small hub motor and battery pack attached to the frame. These bikes operated on some combination of human-power and electric-power. As technology evolved and demand for larger vehicles grew, producers of electric two-wheelers began to ignore the limits on vehicle speed and weight. Regulation was lax, and consumers wanted faster and heavier two-wheelers that mimicked gasoline scooters. Soon these faster and heavier two-wheelers were common.

As technology evolved and demand for larger vehicles grew, producers of electric two-wheelers began to ignore the limits on vehicle speed and weight.

Higher speeds have undeniable benefits to users, but higher speeds can also have costs in the form of safety&#;both the safety of users and the safety of the public. Electric scooters have many of the features of traditional gasoline scooters, often including speedometers, turn signals, brake lights, disk brakes, and headlights. These features can potentially make scooters safer than bikes, but the scooters&#; increased speed and weight, which increase the severity of any crash, may counteract any safety benefits from their greater visibility and stopping power. As a result, bicyclists became increasingly concerned about sharing their lanes with larger, more powerful scooters.

In response to the perception that two-wheelers had become unsafe, several cities imposed more stringent regulations, forbidding electric scooters in urban centers while gradually allowing higher speeds and weights in outlying areas. And in December , the central government reiterated its commitment to the &#;20/40 rule&#; mandating that two wheelers maintain a 20km/hr speed limit and 40kg weight in order to be classified as electric bicycles. Faster and heavier vehicles can still be manufactured, but they are now classified as electric motorcycles, requiring registration and driver licensing. The classification also moves electric scooters out of the bicycle lane. However, the central government continued to allow local governments some latitude in enforcing this new regulation. Therefore, the true impact of this pronouncement may be limited.

Two-Wheelers and Mode Shift

Has the growth in two-wheelers resulted in a significant shift in travel modes? Although China&#;s electric two-wheelers are most similar to bicycles and motorcycles, they compete for ridership not just with other two-wheeled vehicles, but also with buses. A series of surveys in several major cities over four years shows the effect of electric two-wheelers on other transportation modes (Figure 1). In Kunming and Shanghai, which both have high quality transit systems, a majority of the people using electric two-wheeler would otherwise be bus riders. In Kunming, over a four-year period, electric bike riders seem to be capturing more of the bus mode share and the overall trend toward motorization is also pushing bicycle ridership down. In Shijiazhuang, users of electric two-wheeler riders would more likely be bicyclists than bus-riders. The share of two-wheeler riders who would otherwise use cars in some form (be it a personal vehicle or taxi) is relatively small but environmentally significant (cars have much higher emissions than electric two-wheelers, as I discuss below, so taking even a small number of them off the road can substantially reduce pollution). In Kunming, the share of electric two-wheeler users who would otherwise use cars has increased from 1 in 6 in to 1 in 4 in .

Environmental Impacts

Part of the consumer appeal of electric two-wheelers is their low cost, and their cost is low in part because they are low-weight and low-power, making them among the most efficient vehicles on the road. The electricity costs of a two-wheeler are about 0.2¢ per kilometer. Battery replacement costs can be higher, about 1¢ per km, depending on battery size and fluctuations in lead prices. By way of comparison, gasoline costs for cars average 8¢ per kilometer and for motorcycles 3¢ per kilometer. The average bus trip also costs 3¢ per kilometer.

The primary factor determining the environmental impact of electric two wheelers is the method used to generate the electricity that powers them.

The low power required to operate electric two wheelers also makes them relatively clean. The primary factor determining the environmental impact of electric two wheelers is the method used to generate the electricity that powers them. Over 80 percent of China&#;s electricity generation relies on fossil fuels, mostly coal. However, different regions rely on fossil fuels to different degrees, so the location of a two-wheeler can significantly influence its environmental impact.

Figure 2 shows average emission rates (weighted by total electricity generated in the region) of several pollutants from electric two-wheelers. In general, the provinces with the fewest emissions are in the southwest, which has cleaner hydropower sources of electricity, while the provinces with the highest emissions are in the northeast, where virtually all electricity is generated with coal (Figure 3).

Two-wheelers&#; low emissions, however, are partly countered by their growing use of lead batteries. Over 90 percent of electric bikes in China use a lead battery, and each battery typically contains 10 to 20 kg of lead. Some of the largest electric scooters use even heavier batteries. Mining, producing and even recycling lead batteries can generate substantial pollution. While it is true that almost all motorized vehicles use lead acid batteries, none use them at the rate electric bikes do. Each electric bike requires a replacement battery every twelve to eighteen months, resulting in a tremendous amount of lead released to the environment. Moreover, battery recycling in China is poorly regulated, and generally only captures 70 to 80 percent of the used lead. This low recapture rate is largely due to a burgeoning industry of small, informal recyclers and manufacturers, whose existence is fueled by the popularity of two-wheelers. The high rates of lead emissions not only undermine the environmental advantages of two-wheelers, but also pose health threats to people who live near lead production and recycling facilities. In the past year, a number of high-profile lead poisoning cases have been reported around lead and battery manufacturing facilities throughout China.

Battery recycling in China is poorly regulated, and generally only captures 70 to 80 percent of the used lead.

Nevertheless, electric two-wheelers have some clear environmental advantages when compared to competing motorized modes. Table 1 shows the average emission rates, including vehicle and fuel production emissions, of several vehicles that electric two-wheelers compete with for mode-share. Even compared to a loaded bus (the vehicle most two-wheeler operators would otherwise be using), electric two-wheelers emit less carbon dioxide (CO2), carbon monoxide (CO), and nitrogen oxides (NOX). However, they emit more particulate matter (PM), sulfur dioxide (SO2) and hydrocarbons (HC) than buses, because they draw power from China&#;s coal-based power grid. (And again, because different regions depend more or less heavily on coal, these comparisons can vary by region).

Compared to cars or motorcycles, electric two-wheeler emissions are significantly lower on almost all metrics. The big exception is lead (Pb). Because of their batteries, electric bikes emit far more lead than other modes, often by one or two orders of magnitude. Compared to motorcycles, electric two-wheelers perform very well on all metrics, with the exception of lead and SO2, and cars have higher emissions than two-wheelers in every category except lead. Indeed, for most pollutants the emission rates of cars are one or two orders of magnitude higher than electric two-wheeler emissions.

For example, a new car in Beijing that meets emission standards for particulate matter will emit 0.005 grams per kilogram of particulate, and it will expose nearby residents to 73 parts per million (ppm) of exhaust emissions. For each million grams of particulate matter emitted, in other words, only 73 grams are inhaled. By contrast, an electric two-wheeler in Beijing, with an emission rate of 0.008 g/km (1.6 times higher than the emission rate of gasoline car), will expose the population to only 6 ppm of the total PM2.5 emissions, a mere eight percent of a gasoline car&#;s exposure rate. This implies that the public health impacts of electric two-wheeler emissions could be much lower than the public health impacts of automobiles, although the electric two-wheeler&#;s emission rate is higher. The public health impact of electric two-wheelers is even more advantageous when they are compared to diesel cars and buses, which have higher tailpipe emissions and exposure rates.

Local emissions, however, don&#;t tell the whole story. Electric two-wheelers are charged from the grid, so they contribute to pollution from power plants. Most pollutants from tailpipes are emitted in urban areas, and generally inhaled by the urban population. But power plants are frequently in rural areas, and their pollutants might be inhaled primarily by rural residents who live nearby, and who are not responsible for the bulk of the emissions. Thus while electric vehicle emissions and exposure could be lower overall, a large shift to electric vehicles could also shift urban transportation pollution onto rural populations.

Looking Beyond China: A Global Future for Electric Two-Wheelers?

Electric two-wheelers are not nearly as popular outside China, probably because in other countries traditional motorcycles are not as severely restricted. In other Asian countries, electric two-wheelers compete directly with gasoline scooters. Electric two-wheelers in China, however, compete mostly against buses or bicycles. Moreover, because electric two-wheelers in China are slower and lighter than gasoline motorcycles (a result of the government regulations mentioned above), they are not a very viable export product. Electric two-wheelers that China exports to Asian countries like India and Vietnam have difficulty competing with faster gasoline two-wheelers; the combined Indian and Vietnamese market for electric two-wheelers is only one-tenth the size of China&#;s. In response, some electric two-wheeler companies have begun marketing vehicles that can compete with gasoline vehicles on price and performance, but some of the initial models were low-quality, and consumers remain wary. However, if fuel prices rise in Asia and electric vehicle technologies mature, electric two-wheelers could become more popular, particularly if governments give them favorable treatment through reduced licensing requirements or sales tax incentives.

Electric two-wheelers in China compete mostly against buses or bicycles.

Absent such interventions, however, it is unclear how popular electric two-wheelers will be outside the unique circumstances of congestion and regulation that characterize Chinese cities. Some electric two-wheelers&#;primarily electric-assist bicycles with advanced battery technology and performance&#;are becoming popular in some European and North American cities. These vehicles are designed to travel longer distances and at higher speeds. As a result, they tend to be larger than traditional bicycles, which raises significant questions about their role and place in the transportation system. Nevertheless, electric two-wheelers in Western countries could help overcome many of the challenges associated with traditional bicycles by increasing their range, making difficult terrain more manageable, and reducing rider fatigue. But Western nations, like China, will need to devise and enforce rules defining how two-wheelers can safely travel.

Conclusion

The Chinese electric two-wheeler market has exploded in the last decade. Streets in Chinese cities teem with electric two-wheelers vying for valuable space. The two-wheelers provide a tremendous amount of low-cost mobility, no tailpipe emissions, some of the lowest overall emissions of any motorized mode, and almost no noise. It is tempting to see China&#;s experience as a prologue for the mass-adoption of electric two-wheelers in other parts of the world, and two-wheelers could well fill a niche in the West.

The two-wheelers provide a tremendous amount of low-cost mobility, no tailpipe emissions, some of the lowest overall emissions of any motorized mode, and almost no noise.

Yet China&#;s experience also shows us the complications that can arise when another set of users is mixed into an already-crowded road system. In response to concerns about safety, the Chinese government has had to reinforce its distinctions between bikes, electric bikes and scooters, and Western countries will also require unique policies to classify electric two-wheelers and integrate them into the existing transportation system. Whether electric two-wheelers will be able to compete in the open market against gasoline two-wheelers also remains uncertain.

While still not entirely mainstream, the idea of an exciting electric motorcycle shouldn't sound farfetched. Electric motorcycles may not offer all of the traditional benefits of a gas powered motorcycle, like the vibrations or the noise you&#;ve come to love, there is a lot that may surprise you about getting an electric motorcycle.


Here are the top 5 reasons why you should consider buying an electric motorcycle.


Reason 1: The Savings


This is easily the biggest selling point for electric motorcycles. While the cost of the bike itself can be the same, and sometimes more expensive than their gas-powered counterpart, the ongoing costs of an electric motorcycle are way lower.


The total savings depends on the specific model of bike you get, and what gas-powered bike you're comparing it to. However, is all cases, the refueling cost of an electric motorcycle is far lower than a traditional motorcycle.


Reason 2: Easier Maintenance


Without all of the intricacies associated with a combustion engine, the maintenance of an electric motorcycle is generally much easier. With an electric bike, you don't have all of the fluids to worry about like you do with a gas engine. This alone means a lot less can go wrong, and if something does go wrong, there is a lot less to troubleshoot mechanically.


However, it&#;s worth nothing, as with most electrical devices, when something does go wrong, it takes a certain set of skills to fix the issue. Rather than being well versed in mechanics, to fix an electric motorcycle, you should have some level of programming skills. With this being said, when issues do arise, they can be a hassle but overall scheduled maintenance on an electric motorcycle is easier for the average rider.


Reason 3: Ease of Use


With an electric motorcycle, to get going all you have to do is twist the throttle and you're off. You don't have to worry about shifting, stalling, or any of the other headaches that go along with the traditional manual transmissions you find in gas-powered motorcycles.


Reason 4: They Are Great For Road Trips


You can still take a road trip on an electric motorcycle without having to worry. With the average range on a single charge being around 150 Km, you can rest easy knowing that on a full charge, you can take a considerable trip.


Make sure if you take your electric motorcycle onto the twisties, you get yourself a helmet cam to film it all (learn more about them here). An electric motorcycle can handle just as well as a gas-powered motorcycle and you can go just as many places so you'll want to make sure you get all the beautiful views you see along the way on film.


Reason 5: They Are Better For Commuting & The Environment


Electric motorcycles are easier to commute on because they don't get as hot or uncomfortable as gas-powered motorcycles do. Since there is no gas engine, there is no exhaust. When you mount the bike, you won't have to worry about burning your legs on parts of the engine, or on the pipes. This makes an electric motorcycle a great choice for commuters.


Not to mention, a battery-powered motorcycle is a great way to lessen your personal contributions to C02 emissions in the atmosphere. With an electric vehicle, whether it's a car or motorcycle, you're dramatically lowering your emissions if you plan on commuting on it.


Wrapping it all up


When it comes to electric motorcycles, there is a lot to love. While there are some things they can't do, like match the speed of huge sport bikes, there is still a lot you can do on an electric motorcycle.


The biggest benefit to buying one is by far the savings, but there is more to it than that.
