What is an Electric Bike?

An Electric bike is a bicycle with an added electric motor and lithium battery for powering the motor. However, Pedals are still used when riding it. Yet, the electric motor makes the ride simpler when climbing hills or needing a boost.

An electric bike, sometimes called an ebike, has an e-bike engine or motor to help you in pedaling. An installed rechargeable battery on the bike will provide power to the motor.

There are many types of ebikes with different frame designs available in the market for various purposes such as commuter ebikes, electric mountain bikes, cargo bikes, etc. And each ebike comes with different battery capacities and motor wattages.

An ebike with a 350-watt motor is called a 350w electric bike. Similarly, an ebike with a 500-watt motor is called a 500w electric bike, and so on.

How does an electric bike work?

An electric bike often has a motor on the front or rear hub or in the middle of the bicycle (commonly called the mid-drive motor, powered through the cranks).

The installed motor on the rear or front hub assists in pedaling. The motor’s output depends on how hard your pedaling is and the assistance level you have chosen.

When you push the pedal, a torque sensor gauges your exertion and compares it to the motor’s power output. It is intended that the motor will not assume full control; rather, you should experience steady power delivery that prevents the bike from lurching forward.

One of its numerous advantages is that you still need to peddle and gain exercise when using an electric bicycle. It is feasible to use an electric bike for training & exercise.

You can also use full throttle mode as well but it will consume more battery power resulting in less distance range. The ebike battery, which may be housed inside the frame or attached on the outside, provides power.

While some batteries could be removed for recharging, others can’t be removed for charging. If so, you must have a place to store the bike near a power outlet.

What is Wattage in an Ebike Motor?

The watt ratings on an electric bike motor typically indicate how much power the ebike motor can manage or continuously consume.

There are two types of watt ratings on an ebike motor i.e., peak watt ratings and continuous watt ratings. Peak watt rating means how much power an ebike motor requires to climb steep hills or tough terrains like this.

However, continuous peak ratings mean how much power the ebike motor consumes in an hour. Most of the time brands report only continuous watt ratings of an ebike motor.

Here is the formula to calculate the watt of an ebike:

Ebike wattage = Battery Voltage (V) x Amp of the controller (A)

For example, A 48v ebike battery with a 20-Amp controller would give a maximum power of 960 watts ( 48V x 20 A).

How much wattage do you need on an ebike?

The performance of an ebike depends on the battery’s capacity and motor wattage. So the main question is how much wattage do you need on an ebike i.e., 350w or 500w? It depends on your purpose.

You must have heard, “Higher ebike wattage gives more power, torque, and speed than a lower wattage ebike”. Well, this statement is not always true.

You must also know that the higher-wattage ebikes are expensive and need higher voltage batteries which again increases the charging cost. Whereas, low-wattage ebikes are lightweight, affordable, and need less electricity for charging.

So, If you are going to ride an ebike mostly on plane roads, go for a lower-wattage ebike. And If you are going to ride on hills and indulge in ebike racing, go for a higher-wattage ebike.

You must consider the controller ratings and battery’s voltage and Amp-hour (Ah) while purchasing an ebike. Because the battery provides the power to the motor but the controller decides how much power to transfer to the motor.

So, a controller with higher Amps provides more power to the ebike motor and vice-versa.

For example, a 48V battery with a 15 Amp controller would provide 720 watts of output power whereas the same 48v battery with a 20 Amp controller would provide 960 watts of output power.

So make the decision wisely.

350w vs 500w Ebike: 5 Major Differences

350w vs 500w electric bike motor

As you know that the higher-wattage e-bike motors will provide the following:

  • Quicker acceleration.
  • More power while climbing hills.
  • Better performance for larger riders.

As the old age question goes: Is more really better? But, electric bikes typically aren’t as economical as your typical runabout, just like an elevated car isn’t always as efficient.

A battery will discharge more quickly from an engine with a greater watt rating, reducing the rider’s range.

Here are the 5 major differences between 350w and 500w electric bikes.

Components350w Ebike500w Ebike
MotorA 350w ebike motor is not capable of climbing hills because of less resistance.500w ebike motor provides more resistance and can easily help in uphill climbing.
BatteryIt needs a lightweight battery that also lasts for long hours and distances.It needs a heavy battery that easily discharges because the motor needs 500 watts of output.
ControllerA 350w ebike comes with a basic controller i.e., 10 or 15 Amp.A 500w ebike needs more power output, therefore, it comes with a high power controller i.e., 15 or 20 Amp.
SuspensionLess shock absorbing or sometimes without suspension.Feature a premium quality suspension fork since this ebike is heavy and made for heavy riders.
Top-SpeedUp to 25 mph (40 km/h)Up to 28 mph (45 km/h)

So, A 350W e-bike motor will offer sufficient power for the typical cyclist going slowly on a generally level surface. However, a 500w ebike is more powerful and can be ridden on all types of surfaces by any type of rider.

Let’s learn more about 350w and 500w electric bikes.

350W Electric Bike Features, Top Speed & More

350w ebike motor features

An electric bike with a motor output power of up to 350 watts is known as a 350w ebike. And legally, they are considered class 2 ebikes in the United States.

There are two types of 350-watt motors i.e., Mid-drive motor and Hub motor. A Mid-drive motor with 350 watts is more powerful than a 350w hub motor, It can deliver up to 60NM torque and 500-watt peak output power using pedal assistance mode. Results may vary from person to person.

So, climbing uphill with a 350w mid-drive motor is easy as compared to a 350w hub motor because a mid-drive motor provides 10% more power & acceleration.

Talking about the speed of a 350w electric bike has a speed somewhere between 20-25 mph (30-40 km/h). This speed can go up to 30 miles per hour while riding downhill.

When it comes to battery, A 36v or 48v battery is enough with 10Ah or 15Ah capacity as a 350-watt rating motor needs at least 350 watts of power input from the battery.

A 36v 10Ah would provide up to 360 Wh, a 36v 15Ah would provide up to 540 Wh, a 48v 10Ah would provide up to 480 Wh, and a 48v 15Ah would provide up to 720 Wh.
