Pedal Assist vs. Throttle E-Bikes: Key Features & Differences

The beauty of an electric bike lies in its ability to give you an extra boost of power whenever you want to make a ride smooth and sweat-free. However, the way the motor is activated can make all the difference in your cycling experience. The point is that modern e-bikes may be pedal assist or throttle-controlled, allowing you to ride either with or without pedaling, and you should know which propulsion method works best for you. Therefore, we will compare e-bike pedal assist vs. throttle systems to help you choose a setup that matches your riding style and comfort level.

What is the Pedal Assist System?

A pedal assist system (PAS) is designed to make your pedaling efforts more effective by activating the motor only when you are pushing the pedals. These bicycles are equipped with cadence or torque sensors (or a combination of both) to detect your speed and pedaling motion and adjust the motor’s power output proportionately. PAS systems also offer several assistance modes (typically 3-5) so that you can decide how much help you want. These bikes encourage active participation and make the riding experience feel more natural since they stop moving as soon as you cease to pedal, just like traditional, non-electric two-wheelers.

What is the Throttle System?

The throttle system allows you to ride and control the bicycle’s speed without pedaling (similarly to a motorcycle). In such bikes, the motor is activated using a handlebar-mounted throttle, which comes in the form of a thumb lever or a twist grip. Still, these bicycles have pedals (like any regular bike), so you can also ride them without electric assistance.

Electric Bike Throttle vs. Pedal Assist: Main Differences

A mere pedal assist or throttle definition will not help you determine which propulsion method suits you best. For this, we should puzzle out their key differences to help you choose the right system for your needs. Check out our throttle vs. pedal assist comparison table to know more:

	Pedal Assist System	Throttle System
Activation method	Activated by pedaling.	Activated by twisting or pressing a throttle.
Pedal assist vs. throttle position	Cadence or torque sensors are typically located in the crankset or bottom bracket.	Positioned on the handlebars.
Control over speed	Speed depends on pedaling effort and the selected assist level.	Speed is controlled by throttle input, independent of pedaling.
Physical effort required	Requires consistent pedaling.	The motor provides full propulsion, so no physical effort is required.
Battery consumption and range	More energy-efficient, as it uses the battery to supplement pedaling.	Consumes more battery power, as the motor does all the work.
Pedal assist vs. throttle cables	Uses sensor cables (for cadence or torque sensors) connected to the pedal system.	Uses throttle cables to connect the throttle to the motor.
Impact on riding style	Feels more natural, intuitive, and fitness-oriented.	Feels more like a motorcycle, allowing for relaxed riding with less physical exertion.
Legal considerations	Classified as Class 1 or Class 3 bikes, depending on their motor power and speed. Class 3 PAS bicycles have a maximum speed of 28 mph and require a license in some US states.	Classified as Class 2 bikes; they do not require licenses, registration, or insurance if their motor power is less than 750W and the maximum speed is 20 mph or lower.

Pros and Cons of Pedal Assist Bikes

Comparing the pros and cons of e-bike throttle vs. pedal assist systems may also help you choose the most suitable option for your cycling needs and preferences. First, let’s determine the strengths and weaknesses of pedal-assist bikes:

Pros:

Conserve more energy and have an extended battery range for longer rides
Encourage riders to stay active, improving their physical and mental health
Offer more natural cycling experience
Allow for adjusting assist levels to balance effort and speed
Deliver power gradually, which makes them safer to ride
Easy to adapt if you are transitioning from a conventional bike
More eco-friendly than throttle bikes

Cons:

Riders must pedal continuously to engage the motor, which may be challenging for those with limited mobility or physical fitness
Pedal-assist models are more expensive than traditional bikes
Require more maintenance

Pros and Cons of Throttle-Controlled Bikes

Let’s consider the advantages and disadvantages of throttle-controlled electric bikes so that you know if it’s worth choosing them:

Pros:

Instant motor power and acceleration
Straightforward bike control
Reduced strain on legs due to pedal-free riding
Versatility in riding styles, as you can choose if you want to stay active or passive during a trip
Less bike maintenance is required
More exciting riding experience

Cons:

Shorter battery range
Fewer health and fitness benefits compared to pedal-assist bikes
More expensive than traditional bikes available for purchase or rent in local stores
Less natural cycling feel

When to Choose Pedal Assist Bicycles

Still wondering which propulsion system to choose – pedal assist or throttle? We have already considered the ideal user profiles for each bike type to help you decide. So, pedal-assist bicycles are often used by:

Fitness enthusiasts willing to exercise during their cycling sessions
Eco-conscious riders
Daily commuters and adventure seekers riding on mixed terrains
Touring cyclists traveling long distances
Families seeking safety and stability when carrying kids or dogs

When to Choose Throttle E-Bikes

Throttle-controlled bicycles are especially popular among:

Casual riders who prioritize comfort over physical engagement
Cyclists with limited mobility or physical fitness
Commuters traveling short distances
Non-cyclists seeking an easy transportation option
Delivery workers

E-Bikes with Both Pedal Assist and Throttle

Some electric bikes (e.g., Ferla Royce II and Royce MAX) combine the best of the two worlds and feature both a pedal assist system (with cadence or torque sensors) and a throttle mechanism, allowing cyclists to select their preferred riding mode. Need to navigate through heavy traffic without breaking a sweat? Twist a throttle! Want to reach your destination as quickly as possible? Turn on the highest level of pedal assistance!

E-bikes with both pedal assist and throttle offer many advantages:

Versatility in riding styles, as you can get electric assistance with or without pedaling
High appeal to both active cyclists and those with mobility limitations
Improved safety and comfort when carrying kids, pets, or cargo
Ability to cover longer distances whenever needed
More enjoyable cycling experience on rough and hilly terrains

Summary

The choice between the electric bike pedal assist vs. throttle system depends entirely on your riding style, the distances you travel, and how much exercise you want. Each propulsion method has its benefits that cater to different cycling needs and expectations.

Pedal-assist bikes deliver a more natural cycling experience, encourage physical activity, and allow for longer rides. Throttle-controlled models, in turn, provide immediate acceleration and continuous motor power without pedaling. You can also purchase an e-bike with both pedal assist and throttle to get the most out of your rides. Whatever option you choose - pedal assist or throttle - Ferla has a wide range of quality models for any need!
