What is an ebike?

If we go by the legal definition provided by the California vehicle code, an “electric bicycle” is a bicycle equipped with fully operable pedals and an electric motor of less than 750 watts (i.e., 1 horsepower).

In simple words, Electric bike or ebike is a simple bicycle that gets help from an ‘Electric motor’ when you are paddling. The motor gets power from a rechargeable battery, mounted on the ebike.

The popularity of electric bikes is skyrocketing in the US, Canada, and Europe due to regular improvements in better battery technology and more efficient designs. Also, Electric bikes are offered in a wide range of varieties, including Commuting bikes, Mountain bikes, Folding bikes, Fat tire bikes, Cargo bikes, and so on. Which makes it even more convenient and fun to use.

History and Evolution of E-Bikes

To be honest, the concept of electric bikes is not new; it has been evolving since the 19th century. The first patent for an electric bicycle was filed by Ogden Bolton Jr. in 1895, featuring a direct-drive hub motor. Over the period, it has evolved till now.

Early e-bikes were bulky and had limited battery life. The turning point came in the 1990s, when technological advancements in batteries and motors made e-bikes more viable for everyday use. After the introduction of rechargeable lithium-ion batteries in the 1990s. It significantly improved the range and efficiency of e-bikes.

In recent years, ebikes have become more user-friendly, more efficient, and faster due to the introduction of features like pedal assist system (PAS), throttle and activity display which provide real-time data and navigation.

How does an electric bike work?

The main parts of the ebike are the battery, pedal assist system (PAS), throttle, controller and display. The working of an electric bike is explained below.

The battery

It plays a huge part in how electric bikes work.
Modern e-bikes use rechargeable lithium-ion batteries.
The battery powers the motor and other electronic components.

Motor

It provides assistance to the rider. There are two types of motors that are used in ebike.
Hub drive: Located in the center of either the front or rear wheel, these motors provide direct power to the wheel.
Mid-Drive Motors: Positioned in the middle of the bike, usually integrated with the crankshaft. These motors offer a comfortable ride and more efficient power delivery.

Pedal assist system (PAS)

PAS uses sensors to detect pedaling and assists accordingly.
There are three modes of PAS: low, medium and fast.
In some ebikes there are five modes : 0 to 5. (based on assist they provide), the rider can choose according to his/her needs. For example, if you are riding on a flat road or path, then use 0 or 1 mode. However, if you are riding in mountains or hills, the PAS mode between 2 to 5 is recommended for a comfortable and less-effort ride.

Controller

It regulates the power from the battery to the motor based on input from the rider, such as the level of pedal assistance or throttle use.
Controller allows you to choose the level of assist you need from PAS and throttle.

Throttle (optional)

By using throttle you can drive ebike without pedaling. Which is very helpful to quick start ebike, especially in hilly areas.
Some electric bikes offer pedal assist as well as throttle. In a class 2 ebike the throttle is a must.

Display panel

The display panel shows all important parameters like speed, mode of PAS, distance covered and battery level.
In different ebikes, it even offers additional features that track real-time data of the rider. which is very helpful for health-enthusiastic people.

So in simple words, in electric bike battery gives power supply to the motor, which provides assist to the rider. The pedal assist sensor takes input from the rider and provides assistance accordingly.
