What Are E-Bikes & How Do They Work?

What Is An E-Bike?

E-bike is short for electric bicycle

So, how does this differ from a motorcycle you might ask?

The first and most obvious difference is the appearance—no one would mistake one for the other.

That’s right, an E-Bike in St. George UT or anywhere else is simply a regular bicycle suped-up with various electrical components like a battery, controller, and motor. These components are integrated seamlessly into the bike’s design.

How Do E-Bikes Work?

bike rentals zion national parkOur St. George E-Bikes work just like regular bicycles and they essentially have the same parts as well. 

The purpose of the electric component is to augment the human power that goes into riding them, rather than totally replacing it as is the case with a motorcycle. 

This is great for people who don’t want to deal with the hassle of long, uphill climbs, headwinds, and other obstacles.

In short, E-Bikes allow you to travel farther and faster without all of the extra work.

What Components Go In An E-Bike?


There are many different power ratings available for E-Bike motors ranging from 200W to 1000W and beyond.

The higher the number, the more weight the bike can pull with greater ease.

The motor’s design and location plays a role in how an your St. George E-Bike will work.

It’s most common for E-Bikes to have the motor integrated into the front or rear wheel. It then pushes or pulls the wheel along.

There are also E-Bikes with mid-drive motors integrated with the gears and crank, which offers a number of advantages like better hill climbing, handling, and overall performance.


It’s important to choose the right battery for your E-Bike, as it can greatly affect its range, style, and weight.

The battery plays a very important role, as it powers the motor which provides you with all of the advantages of the E-Bike.


The controller is how you operate the electric aspect of your electric bike. It’s usually located on the handlebar and comes in two main styles—pedal-activated and throttle based. The former doesn’t need to be engaged, it simply works whenever you start pedaling—the latter works via a simple throttle mechanism, usually a twist-grip or thumb-press style, which allows you to engage the electric assistance if and when you need it.

Do E-Bikes In St. George Require A License?
