Sales of pedal-powered bicycles and electric bikes were on the rise even before the coronavirus pandemic left many consumers spending more time at home, with less need for a car. Since then, bicycles and their electric-motor-powered cousins have been in high demand all over the U.S. as people search for new ways to get around.

Sales for all types of bicycles rose 63 percent between June 2019 and June 2020, according to the NPD Group, a market research company. Sales of e-bikes with an average price of more than $1,000 saw a 190 percent increase as of June compared with the year before.

Getting Started

If you’re thinking about buying an electric bike, commonly known as an e-bike, first consider how you intend to use it. There are almost as many types of e-bikes as there are pedal-powered bicycles, and many of them do specific things very well. A big factor in your decision will be where you live, because climate, the presence (or lack) of bike lanes, how far you want to ride on a regular basis, and how your locale classifies and regulates e-bikes will affect how you can use it.

A few states treat e-bikes like other motorized vehicles and require riders to have an operator’s license to use one on public roads. More than half of the states recognize e-bikes as a type of bicycle depending upon how fast they go and how power is applied (for example, by pedal-activated power or a hand control).

Currently, there are three general e-bike classifications, and some gray areas. 

More on Bicycles

Class 1 covers pedal-assist bikes, which power the electric motor as your foot applies pressure to the pedal. There's no throttle to get the bike going; the electric part works only when the rider is pedaling, and the e-assist cuts off at speeds above 20 miles per hour. (It's possible to get even conventional bicycles moving faster than that on a steep enough hill.) 

Class 2 bikes also have an electric motor that works up to 20 mph, either while the rider is pedaling (pedal assist) or with electric propulsion alone via a throttle control.

Class 3 limits an e-bike’s pedal assist to 28 mph and requires a speedometer.

Where you can ride an e-bike varies based on location, so it’s best to check local regulations before using one on a bikes-only trail. (Powered bicycles could be prohibited.) It's also strongly recommended that e-bike riders wear helmets, even if the locale doesn’t require it.

There are also more powerful electric bikes that are only supposed to be ridden in designated off-road areas. These e-bikes can look like bicycles, but functionally are more like motorcycles. For the purposes of this guide, we’ll focus on the three classes that most resemble a conventional bicycle.

Why Buy an E-Bike?

There are many reasons people buy e-bikes, but we found after talking to experts and riders that the main ones are for commuting, recreation, and hauling light cargo. Amid the pandemic, health concerns have been another driver of increased bicycle sales. If consumer demand tells the story, bicycles have been a good transportation alternative for urban and suburban commuters wishing to avoid using public transportation. They can also be a good form of socially distanced recreation.

“There's no one demographic that rides an e-bike,” says Sarah Johnson, a cycling expert and advocate who used to own a bicycle shop in Omaha, Neb., that sold e-bikes. “It’s young people who don't want a car; it's older people who want a little help so they can still ride a bike; it's commuters who don't want to get all sweaty on the way to work.”

According to the Department of Transportation, nationwide survey data show that more than half of the trips people take are 3 miles or less. And 72 percent of those are made by car; fewer than 2 percent are made on a bicycle. The National Conference of State Legislatures (NCSL) says that distance is feasible for bicycles, particularly e-bikes.

Pricing

Prices for e-bikes range from less than $500 to thousands of dollars. For most consumers, the higher end of the scale will be about $6,000 to $7,000. According to NCSL, the average price for an electric commuter bike is $2,000 to $3,000, compared with $1,000 for a conventional midrange commuter bicycle.

Micah Toll, who digs into the particulars of e-bikes and other battery-powered personal transportation for Electrek, a website focused on everything electric, says budget is an important consideration for e-bike shoppers. He advises consumers to avoid the extreme low end of the e-bike range, where cheaper components can affect overall quality. He also says first-time buyers might not want to get the most expensive models, to give themselves time to figure out whether or not they like riding one.

“The $1,500 range is the sweet spot right now,” he says. “Manufacturers are making good-quality bikes but aren't using top-shelf components. It's a good balance for people who don't want to spend a fortune but also don't want the bike to fall apart after a year or two.”

Commuter Bikes

Commuter bikes come in a variety of styles but are meant to serve as practical transportation. For many consumers, e-bikes represent a much more cost-effective alternative to expensive, fossil-fuel-dependent automobiles, or, at the very least, a way to cut down on the number of cars in the driveway. Many people like the fact that they can commute on an e-bike without getting too sweaty on the way to work, and that they aren’t as likely to get stuck in grinding car traffic.

Steve Volkers, who lives in suburban Maryland and commutes several miles over rolling hills, says he actually gets to work a little faster on his e-bike because he doesn’t have to sit in the Washington, D.C. area’s notorious car traffic.

Glen Mayenschein, who works several miles from his home in northern New Jersey, has been commuting exclusively by bicycle for 20 years, and, at age 62, decided to buy an e-bike. “I have a bad knee, so I figured I’d make it easier on myself and get an electric bike,” Mayenschein says, noting that he rides a hilly route to and from work. “I like riding a bike, and I still ride regular ones from time to time, but now I mostly ride the electric one.”

Commuter bikes vary from the type with narrow tires and straight handlebars city dwellers are used to seeing in conventional form to beefier models with fat tires and thicker frames. Experts say fat-tire bikes—which can be difficult to get going on pedal power alone—are gaining in popularity as electric versions have become more widely available. There are also folding e-bikes that are easier to stow in a tight storage area or aboard a train or bus.

Recreational Bikes

According to NPD, the bulk of the pandemic bicycle sales boom has been for enthusiast bicycles like road and mountain bikes. Road and mountain biking already were popular recreational activities, and the addition of electric motors has expanded their appeal. A recent study published online in July in the International Journal of Environmental Research and Public Health found that the physical fitness aspect of cycling should assuage any concerns that assistance from electric motors will undercut the exercise benefits of pedaling. (It's important to note that the study was limited to two weeks, and that further research is necessary to confirm long-term benefits.) The American College of Sports Medicine recommends at least 150 minutes per week of moderate cardiovascular exercise, and the July study found that e-bike riders tended to achieve that goal and more. Although their heart rates were lower on average than those of conventional cyclists, they tended to spend more time riding.

As with conventional bicycles, there are several different types of e-bikes, each with a special purpose, whether it’s riding mountain or forest trails, taking long rides on the open road, or cruising around at a leisurely pace near home. Some conventional cycling purists knock e-bikes because of the greater ease of pedaling, but some converts have told us they love them.

The extra boost from a battery and electric motor has also opened up cycling to people who might not otherwise have been able to ride. Sarah Johnson, the Omaha cycling advocate, says she faced having to give up cycling when medical problems made it difficult for her to pedal a conventional bicycle.

“I used to be an e-bike hater, but when I realized that it was e-bike or no riding, I realized how great they are,” she says. "I'm feeling better, but I don't think I'll ever get rid of my e-bike.”

Performance Road Bikes
The defining characteristics of a road bike are usually a lightweight frame, skinny tires, and drop-down handlebars that help the rider maintain an aerodynamic riding position. It’s not unusual to see a cluster of bright-shirted cyclists pedaling furiously down a bike trail or along the side of the road on lightweight speed machines. Like their pedal-powered counterparts, electric road bikes feature slimmer, lighter components and require an aerodynamic riding position—both meant to increase efficiency over long distances. The assistance offered by an electric motor makes it possible to cover longer distances and handle steep grades with less of the fatigue associated with conventional bicycles.

Even though they’re fast and relatively light, performance bikes still aren’t for everyone, because the aggressive riding position can be uncomfortable for some riders.

Mountain Bikes
With beefier frames, bigger tires, and—sometimes—long-travel suspension components, mountain bikes are built to handle trails, large rocks, logs, and other rough terrain and obstacles. A spin through mountain bike racing videos on the internet reveals that they’re sometimes expected by their riders to handle much more than that—big air jumps and rough terrain, among other demands.

Of course the fun part is the faster, more effortless downhill portion. Getting there usually involves a demanding pedal up steep grades on loose terrain. Adding an electric motor to a mountain bike makes a lot of sense for someone who wants to experience the thrill of downhill riding but may not have the fitness to handle the grueling uphill slog. The e-bike segment makes bikes with larger tires—which are more difficult to pedal using leg power alone because of the increased weight and rolling resistance that comes with their beefy wheels and tires—more appealing, and also makes it possible to do more riding in a day thanks to reduced fatigue. Electric mountain bikes aren't permitted on some trails, so be sure to check state and local regulations.

Hybrids and Cruisers
Hybrids offer a combination of road bike efficiency and the more upright riding position preferred by mountain bikers and commuters. They usually have straight handlebars. This type of bicycle can be a good all around setup for those who seek the best of both worlds. Cruisers offer a relaxed, comfortable upright seating position and often a softer ride due to bigger tires and cushier seats. Look for swooping handlebars that keep a rider's arms a relaxed distance from the body. The addition of an electric motor to either of these configurations makes it possible to use a thicker frame and wider tires to soak up bumps in the road. Volkers, the Maryland commuter, bought this type of e-bike because he can ride it on light off-road trails and paved roads with ease.

Cargo Bikes

Cargo bikes are built to haul cargo and extra passengers. With strong frames, fatter tires, and robust components, they're the industrial beasts of the two-wheeled world. Pedal-powered cargo bikes have been around for a while. They can be configured with rear-mounted seats or cargo racks, or front-end cargo boxes supported by one or two wheels. Bicycle taxis can also be included in this group; the two-wheeled models are popular for urban delivery and for ferrying children.

The advantages of adding electric power to a platform designed to haul heavy loads seem obvious. Adding more weight to anything makes it more difficult to move around, and electric propulsion can be a game changer for anyone who wants to use a bicycle as an alternative to a car, such as to run errands and carry large loads of groceries, packages, or passengers. E-bikes—although not necessarily the heavy-duty cargo variety—are also popular among urban food delivery riders who want to avoid car traffic and double-parking.

Safety Considerations

E-bikes can travel at speeds similar to conventional bicycles, and they carry the same safety risks. But models that can travel at 20 mph or more add another level of risk to the equation. Higher speeds mean the rider has less time to slow down or stop. Whether riding a bicycle or a motorcycle, the results of even low-speed crashes—especially when cars and trucks are involved—can be painful and even fatal. A 2019 study in the journal Injury Prevention found—based upon an examination of emergency room visit records—that e-bike riders were more likely to suffer internal injuries than those riding conventional bicycles.

The easiest and most obvious way to avoid a serious head injury is to wear a bicycle helmet. A review of bicycle helmet research published in the journal Injury Prevention in 2007 says that wearing a helmet can reduce the chance of serious head injury by 63 percent to 88 percent. Bright clothing and an adherence to the traffic laws can also help. Another important safety factor for cycling is the availability of dedicated—and especially protected—bicycle lanes. If you must ride in the road with other cars, take into account the prevailing speed and flow of traffic. Motorists may be distracted or driving too fast to see cyclists.

There are aftermarket devices that can be added to any bicycle with features similar to those in the advanced driver assistance systems (ADAS) found on cars and trucks. They include blind spot warning and crash detection. 

There hasn’t been a lot of academic study yet about the injury risks to children posed by the newest e-bikes, but it's best to exercise extreme caution when addressing the needs of any new or inexperienced cyclists. As anyone who fell off a bicycle when they were young can recall, even low-speed crashes and tip overs can result in injury.
