A bike with an electric motor that boosts your pedaling power to make it easier to ride. E-bikes typically have a throttle that lets you operate the motor without pedaling, and they can also be controlled using a controller that allows you to adjust the level of assistance the motor provides.

Some states have laws that regulate the maximum speed an ebike can go and whether or not they require riders to wear a helmet. These restrictions, called class ratings, differ between states and can depend on factors like motor size and whether or not the motor can be used with or without the rider’s pedaling (this is known as pedal assist). Some ebikes have a cadence sensor or torque sensor that detect how hard you are pedaling to add or remove motor power in response. These sensors are smarter and more accurate than simple throttle control systems but can still be overcome by powerful riders or unruly bikes.

In some cases a class rating can be bypassed or altered by cutting a wire or by changing the software on the bike’s computer. This is an issue that some manufacturers have recognized and addressed in their latest designs.

Ebikes have been around for about 100 years and have gained popularity in recent decades due to their increasing affordability, improved performance, and reduced environmental impact. In the United States alone, there are currently about 2.8 million ebikes on the roads, and that number is growing rapidly. Ebikes offer a range of benefits over cars, including zero emissions and less space needed for parking. They are a great way for people to get exercise and experience the outdoors while getting where they need to be.

They can be used to replace car trips, especially those shorter than 20 miles. By replacing these short commutes with ebikes, we can significantly reduce our country’s greenhouse gas emissions and congestion. Additionally, ebikes are more affordable than owning a car and require significantly less maintenance than a vehicle.

However, before you buy an ebike make sure to check with your local laws and consider the fact that these vehicles may not be covered by your home or auto insurance. Additionally, it’s important to practice riding an ebike before you take it out in traffic. Be aware that these bikes are heavier and faster than traditional bikes so be sure to take the time to learn how to maneuver them in busy traffic. And, always use your bike lights and practice slowing down and stopping in safe areas before tackling heavily trafficked streets.
