How do pedal assist bikes work

When exploring electric bikes, we are a sensible approach that e-bikes provide pedal assistance to riders, which is one technological feature that differentiates them from regular bikes. However, it can be difficult to understand pedal assist, how it works, and why it is beneficial. We’ll go over the basics of pedal assist, how it works specifically on Blix Electric Bike models, and why pedal assist is great!

What is pedal assist?

Pedal assist is a mode on your electric bike that uses motor power to help you pedal easier and faster. When you activate pedal assist and select your level of assistance, the motor will produce a certain amount of power as you pedal.

As you ride, you may feel a slight push. Pedal assist differs from throttle mode in requiring riders to pedal in addition to getting power from the motor. The throttle mode eliminates the need for pedalling and relies solely on the motor to propel the bike forward.

How Does It work?

A cadence sensor built into the drivetrain of a pedal-assist bike is used.The sensor tracks each revolution of the pedals as you ride. It then transmits a signal to the electric motor, telling it how much assistance to provide you based on your chosen level of assistance.

Why is pedal assist useful?

All riders benefit from pedal assist since it allows them to ride farther and faster, conquer hills, and overcome limitations. Riders can choose how much exercise they want when they want to push themselves, and they will no longer be afraid of steep hills with the ability to change the pedal assist level.

While some riders argue that pedal assist is cheating, we disagree because we believe it helps riders extend their distance and time on a bike and ride tougher terrain that they may have previously avoided. Pedal assistance can encourage riders to spend more time being active and find an exercise routine that works for them, regardless of their starting physical level. The level of pedal assist selected may gradually decrease from level 5 to level 2, and riders will feel more confident travelling at their assist level.

Furthermore, pedal assist allows commuters to beat traffic and arrive at work faster while feeling refreshed and prepared. With pedal assist, travellers can step off the bike with less sweat and more energy to tackle the workday! The pedal assist makes biking more approachable and enjoyable, especially when riding at 20mph or flying up the hill you’ve always prevented!


Pedal assistance is divided into several settings classifications to accommodate the needs of different cyclists. The lowest pedal-assist setting is for experienced cyclists who only require a tiny amount of assistance from time to time. The medium setting strikes a good balance between routine pedalling power and the built-in power of the motor. The highest settings are for inexperienced athletes or those who want to take a break from exercising because they provide the most pedal assistance. Before riding, it’s critical to understand how your eBike works to figure out what works best for you. Study to find the best settings for you and your way of life.

How do pedal assist bikes work


Many manufacturers will market their bikes as either pedal-assist or throttle operated, but this is somewhat deceptive. There are three distinct ways to operate an electric bicycle, and each method significantly alters how the electric bike rides and performs. The best way to understand ebike operation is to consider it an evolution: from a simple first generation to a more sophisticated third generation (or next generation) system.


A throttle is the most basic way to operate an e-bike. It has been around the longest because it is the most basic. The bike moves when you twist a lever or press a button. When you let go, it comes to a halt.

It’s simple, clear, and functional, but the interface is more akin to a scooter than a bike. The act of twisting or pushing a throttle every time you want power can become tiresome on long trips, so throttle bikes are increasingly being phased out in favour of brake assist systems.


A cadence sensor functions similarly to an accelerator pedal controlled by your feet. The concept is simple: a magnet is attached to the pedals, and a sensor detects the magnet’s movement as you pedal. When you start pedalling, the sensor tells the motor to turn on. Cadence sensors are more intuitive than throttles, but they have significant limitations. The ride can be irregular because the motor wants to turn on at maximum throttle the moment you start pedalling. As you pedal up a hill, the cadence sensor instructs the motor to provide less power when more is required. Overall, while slightly more sophisticated than a throttle, a cadence sensor is still far from an interactive and classy solution.



The best electric bikes are those that seamlessly integrate your pedalling and the motor. The only way to accomplish this is to have a torque sensor.

Torque sensors detect how hard you press on the pedals and instruct the motor how much to turn on based on pedal pressure. When you start climbing a hill, the torque sensor detects that you’re working harder and tells the motor to assist. True magic occurs when a torque sensor is combined with a speed and cadence sensor. This trio can give the motor controller a complete picture of how you ride, allowing it to provide power in just the right amount at the right time.

What is a Throttle?

Some electric bikes include a throttle, typically controlled by a trigger or click mounted on the steering wheel. Some electric bikes, such as the SDRAM X750 S, use a grip twist to speed up. You can ride the bike like a moped or scooter with the throttle without pedalling. While not all electric bikes have a throttle, you can buy throttle-only bikes and bikes that have both.

FAQs(Frequently Asked Questions)

Is It Possible to Stop Pedaling on an Electric Bike?

If the bike is only pedal assist, you must pedal for the engine to engage. However, you can ride an electric bike without the motor’s assistance. This is extremely crucial if your battery dies throughout a ride. The only distinction is that you will have to deal with the bike’s extra weight.

How Much Assist Does an Electric Bike Provide?

The amount of pedal assist you receive is determined by the bike you purchase. Electric bikes frequently have four levels of pedal assist. The highest assistance can range from 250% to 400% of your electric engines. However, the lowest level typically adds between 40% and 60% to your total.

How Fast Do Electric Bikes Travel When Not Pedaled?

When riding a pedal-assist bike, you will mention that the max speed is limited while pedalling. Any additional pedal power you apply will be inefficient when you achieve the limited maximum speed. There is no limit to your speed when pedalling down a hill.

Electric bikes are classified into three types. Class 1 and 2 bikes can help you pedal up to 20mph, while Class 3 bikes can only go 28mph. These top speeds are more than adequate for most people’s rides.

How far can I travel on a single charge?

The most significant factor determining your range is whether you pedal or use a throttle without pedalling, as well as the level of assist you use. Cynergy E-bikes believes in the synergy created by combining human regenerative braking and electric power, so we’ll tell you the estimated range when you do both. Most e-bikes can travel 22-50 miles on a single charge with relaxed pedalling. You’ll go even further in some cases. We have bikes that can travel 80 miles or more on a single charge. Range is also affected by battery capacity, hills, wind, and your size. Many electric bikes pedal as easily as standard bicycles.

So you can extend the range even further by using little or no power on level and downhill surfaces.

How many charges can I get out of a battery?

Most e-bike batteries sold in North America are lithium-ion, which will provide at least 500 full charge cycles before losing about 80% of its original capacity. Some batteries can provide up to 1200 charge cycles. If you recharge the battery when it is only 50% charged, it counts as only half a charge cycle. If you ride your e-bike in pedal-assist mode, which combines pedal power and electric power, you can expect to go 10,000-30,000 miles before replacing the battery.


Pedal-assist is controlled by a number of internal sensors located all across the electric bicycle. These sensors detect cadence and torque and adjust the pedal assist as needed. These sensors work together to tell the pedal-assist system (PAS) when to engage and how much power to provide.
