Florida eBikes in Sarasota, FL is proud to provide customers with information about the different types of electric bicycle pedal assist systems. Electric bicycles, also known as e-bikes, use rechargeable batteries to provide power for the motor, typically located in the frame of the bike.

Pedal assist systems allow riders to get additional power while pedaling to help them go farther and faster. There are three main types of pedal assist systems that can be found on electric bikes: torque sensing, cadence sensing, and pedal and power sensing (or hybrid). It is important for riders to understand the difference between each type of system so they can find a bike that best fits their needs.

In this blog post, we will explore the different types of pedal assist systems and when it may be beneficial to choose each one.

Types of Electric Bike Pedal Assist Systems

There are several types of electric bike pedal assist systems available in the market today. Each type has its own advantages and disadvantages, and it is important to understand what these systems do and which is best for your needs.

In this blog, we will look at the different types of pedal assist systems available in the market, and the differences between them. With this knowledge, you will be able to make an informed decision when purchasing an electric bike.

Cadence Sensing Pedal Assist

Cadence sensing pedal assist systems, or torque sensors, are becoming more and more popular on electric bicycles. As the bike’s motor detects pedaling force based on the rider’s cadence, it is able to react almost instantly. This type of system gives riders better control of their power output and acceleration than any other kind of electric bike pedal assist system.

The motor gears spin as you pedal to provide a smooth ride experience with constant power output. When the rider stops pedaling, the motor is still active but its power output is reduced for a smooth transition into off-power mode. The cadence sensing function ensures that the bike will never over-power itself or the rider’s cadence. This type of system also maximizes energy efficiency and minimizes battery drain while pedaling so riders can get more miles out of a single charge.

This type of pedal assist system can also be programmed to adjust how much assistance it provides based on your desired ride style. Some systems allow you to select different levels of assistance that can range from conservative riding styles to performance-seeking motors that deliver maximum power at all times while allowing you to tailor your own individual level of assistance based on your preferences. This ability helps riders discover their ideal level of comfort and helps them make even better use out of their electric bicycles by finding their preferred combination settings for speed, torque and electricity levels easily and quickly without having any prior knowledge about electric bikes or motors in general!

Torque Sensing Pedal Assist

Torque sensing pedal assist systems measure your pedaling power output and provide assistance in proportion to your effort. The harder you pedal, the more assistance the bike will provide. Such systems are similar to hub-based motors because they send their power through the chaindrive instead of direct to the wheel, but they tend to be more efficient and offer more natural performance.

Unlike simplified hub motors, sophisticated torque sensing systems allow for different levels of assist depending on how much power a rider wants to put in — from lightly assisted pedaling up to full motorized riding. The electronic torque sensor itself is installed into the bike’s crankset so that it can measures each rotation of a single crankarm and adjust power accordingly. Such systems also may include cadence or cadence/speed sensors that help optimizes assist for maximum efficiency. They may even include temperature or current sensors for added protection against overheating or overloading due too aggressive riding conditions, making them ideal for mountain biking or other high-power activities.

Overall, torque sensing systems are considered by many riders as being much smoother and providing more natural riding experience than simplified hub motors can offer.

Speed Sensing Pedal Assist

Speed sensing pedal assist is a type of electric bike power system that helps cyclists ride with more ease and comfort. This system uses a speed sensor mounted on the bicycle’s hub to detect the bicycle’s speed, and then adjusts the motor’s power accordingly. Generally, this type of system is most commonly used on hybrid or mountain bikes.

A cyclist using a speed sensing pedal assist electric bike must first determine their desired power level for the ride. Some systems also let riders adjust individual settings such as power levels and overall power output for each gear. After this has been set, the system uses its own sensors to detect how fast the bike is pedaling and amps up or amperage depending on how much help the cyclist needs at that moment in time.

The benefit of a speed sensing pedal assist system compared to other types of electric bike systems is its ability to account for changes in terrain or road irregularities that may require more motor torque than originally planned. By detecting these changes and providing an increase in amperage when needed, it ensures that cycling remains comfortable even when riding over rough terrain or up steep hillsides.

Benefits of Electric Bike Pedal Assist Systems

Electric Bike Pedal Assist Systems (EPAS) can help enhance your riding experience and make cycling more enjoyable. They are an efficient way to make your rides easier and more efficient without having to expend too much energy.

To understand the different types of EPAS and the benefits they can offer, read on.

Improved Efficiency

Riding a bike with an electric pedal assist system improves efficiency. With the power of electric motors, riders can accelerate faster, ride longer distances and tackle more strenuous terrain. This is ideal for both commuters and recreational cyclists who want improved performance from their two-wheelers.

Whether pedaling up steep hills, riding along flat roads or tackling tricky terrain, electric bike pedal assist systems help cyclists to do all of this and more – meaning you can get more out of your cycling experience.

Increased Safety

Electric bike pedal assist systems help to provide a boost to a cyclist’s pedaling effort and enable them to tackle hills and challenging terrain with relative ease. However, the primary benefit of these systems is increased safety. The additional power provided by an e-bike means that riders are much less likely to lose control of the bike due to tiredness or fatigue.

The extra speed created by the pedal assist system also helps cyclists respond quickly in developing situations on the road and offers cyclists an extra layer of protection by enabling them to accelerate away from potential hazards. Furthermore, electric bicycles can be used in low light conditions thanks to their powerful LED lights which are powered by rechargeable batteries that are built into the bikes.

Reduced Physical Effort

Electric bike pedal assist systems allow riders to increase their speed and go longer distances without exerting themselves physically. The rider determines the amount of assistance required, as well as when it is engaged. By using a pedal assist system, the rider can maintain a more constant level of effort leading to improved performance, greater endurance and less fatigue.

The natural pedaling motion reacts with the motor to help propel the bike forward. This means there is no need for shifting gears, which can often be difficult when climbing hills or riding on uneven terrain. The motor will also provide increased power on flat surfaces or in combination with your pedaling efforts to make riding easier and faster.

Because electric bikes don’t require a lot of physical effort to propel them they are great options for commuters or those who don’t enjoy long rides with intense physical exertion. Electric bike pedal assistance systems are also an ideal option for those who have disabilities which limit their mobility, allowing them to enjoy riding like anyone else without feeling exhausted afterwards.


In conclusion, electric bike technology has come a long way. There are enormous advantages to owning an electric bike when compared to a traditional non-electric one. The different types of pedal assist systems offer users the ability to customize their riding experience to meet their specific needs and goals. Each system’s support level can be adjusted with the turn of a knob or push of a button, allowing riders to further tailor the ride according to their preferences and level of fitness.

Though some newer models feature cadence-sensing systems that automatically adjust the motor’s power output based on your pedalling rate, this is usually available as an aftermarket option for most models. Ultimately it comes down to personal preference for each rider, but when choosing which type of pedal assist power you should look for in your next e-bike, its important not to jump into anything without doing due diligence and research into what type is most suitable for you and your lifestyle!
