How Do Electric Bikes Work? - Different From Normal Bike

It's important to know the difference between watts, voltage, and amp-hours if you're in the market for an electric bike. Learn the lingo and how e-bikes work in this handy guide.

What's electric bicycles?

By adding a motor to the bicycle's frame, electric bicycles make pedaling easier. There are bicycles that can move forward on their own, thanks to the motor, and others that need you to pedal in order to move forward.

Electric bikes are not the same as motorcycles. Electric motors and batteries don't perform as reliably as gas-powered ones. But e-bikes are better for the environment because they don't produce exhaust pollution. They're better for your health because you'll have to exert effort to pedal, which is great for your cardiovascular system.

While the inclusion of a motor may lead you to believe that electric bikes have no practical speed restriction, this is not the case. The definition of low-speed electric bikes is governed by federal laws under the 2002 Consumer Product Safety Act. Thus your maximum speed while using motor assistance will be limited. Speed limits for motorcycles often range from 20 to 28 miles per hour (mph).

States typically divide electric bikes into three categories based on their regulations. In some jurisdictions, only drivers of a certain age can operate certain types of electric bikes, so it's important to research the regulations in your state.

  • Class 1: Bikes are those that provide the rider with a small amount of help as they cycle up to 20 mph.

  • Class 2: Bicycles in the second category are limited to using electric motors that can reach speeds of up to 20 mph.

  • Class 3: Motorcycles have motors that only kick in when the rider pedals, allowing them to reach speeds of up to 28 mph.

Differentiating features from regular bicycles

A Charged Battery

Power for the motor comes from a battery. Watts, volts, and amp-hours all play a role in determining how much power this device can produce and how long it will last. They are located low and in the middle of the bike so that their weight doesn't throw you off balance.

While the switch from lead-acid to lithium-ion cores has reduced the size and boosted the power of bike batteries, it has not reduced their weight contribution.

Electric bikes include sensors that calculate your speed and then tell the motor whether to engage the throttle or the pedal assist. The information gathered by the sensors could include velocity and torque. Even so, their behaviors are interchangeable. The speedometer keeps track of your velocity. Torque sensors, on the other hand, track how vigorously you pedal; greater effort results in greater speed.

The Engine

The engine of an electric bicycle increases the rider's speed and power. Whenever you start to feel tired while riding an e-bike, you can increase your speed by twisting the throttle. Even as you're exerting yourself to peddle the bike, the pedal-assist feature will kick in and lighten the load. The pedal-assist feature of the bike will turn off if you stop pedaling or if you go over the maximum speed it is set to.

The motor converts electrical energy into mechanical energy that helps propel the bicycle. The manufacturer may install the motor in one of three locations: the front hub, the rear hub, or the frame's center. To reduce weight, many modern bicycles omit the front hub motor once common on such machines. These front-mounted motors are a staple of entry-level electric bicycles.

Bicycles with rear-hub motors are propelled using the wheel's rotation in conjunction with the bike's gearing. The motor's proximity to the gearing boosts traction and handling in this configuration. E-bikes in the middle of the price range typically have rear hub motors, which provide increased precision and handling.

High-end, pricey electric bikes have their motors integrated into the frame, located low and center. Because of the motor's placement, you can easily change tires, and the bike will remain stable while doing so.

Electronic components in e-bikes are often housed in weather-resistant cases with tight seals to prevent damage from splashes and drizzle. They're resilient, but you shouldn't leave your e-bike out in the pouring rain or immerse it in a pool of water for long.

Now that you know what makes an e-bike unique, it's time to dive deeper into the various power configurations and what they entail.


Just how long does the battery on an electric bike last?

The battery life of a high-quality eBike can average between two and five years. That, of course, is conditional upon a variety of factors, not the least of which is the battery's type and your own level of care for it. Nowadays, lithium batteries are ubiquitous on electric bikes.

Explain what it is that makes a bike powered by electricity.

Ebikes, or electric bicycles, are regular bicycles that have been retrofitted with an electric bike motor to make cycling easier. A battery attached to the bike will be used to power the motor. To be considered an "e-bike," the motor must only provide supplemental power rather than complete propulsion.

I was wondering if pedaling an electric bike helped charge it.

Most electric bikes do not generate power while being pedaled. In order to function, the batteries must be connected to a wall socket. Certain versions, however, allow for charging while pedaling. However, this is typically a rather inefficient method.

Seeking an EBicycle?

The performance and reliability of your e-bike are affected by its wattage, voltage, and amp hours. Yet, you should also be confident that your bike's build quality can support impressive numbers.
