Can an eBike without pedal assist really be called an eBike? As the core feature that defines the category, PAS (Pedal Assist System) has evolved rapidly—and different brands design it very differently.
So, what would your ideal pedal assist look like? Do you prefer something simple and easy to use, or would you rather have full control to fine-tune every parameter?
What Is Pedal Assist?
In simple terms, PAS provides extra power from the motor on top of your pedaling. It may sound straightforward, but how that power is delivered makes a huge difference to your riding experience.

Some eBikes divide PAS by motor output levels. For example, Blix eBikes offer:
- Eco Mode → light assist, maximum efficiency.
- Tour Mode → about 50% power.
- Turbo Mode → full motor support, maximum speed.
Other eBikes adjust PAS by target speed. These systems constantly push maximum power until you reach the set speed. This can feel unnatural: you might pedal harder but not go faster, or hear loud motor noise when the bike accelerates. These models often rely on cadence sensors instead of torque sensors, which means they can’t “read” how hard you’re pedaling—leading to a less refined riding experience.

Common PAS Designs on the Market
Different brands take different approaches:
Some, like Blix, label modes clearly (Eco, Tour, Turbo, Auto), making it intuitive to understand.
Others simply use a level system (1–5), where 1 is minimal assist and 5 is max.
Premium brands may allow detailed customization—letting you fine-tune the output of each mode through an app. Blix also offers this level of flexibility for riders who want precise control.

The Blix Advantage: AUTO Mode
So, is more detail always better? Or is simplicity the real goal? In practice, what most riders need is intelligence.
Why? Because your needs change constantly:
You might start in Eco Mode for exercise, then suddenly face a hill that calls for Turbo.
You might want faster speeds on open roads, but in traffic, Turbo could be too much.
Constantly switching modes can be distracting and inconvenient.
That’s why Blix developed AUTO Mode.
AUTO Mode uses an AI-powered chip and torque sensor to analyze your pedaling force, terrain, and riding style in real time. It then delivers exactly the right amount of support—no manual switching needed.

The result? Riding feels seamless, natural, and empowering—like you simply grew stronger legs. It’s not just a bike supporting you; it feels like the bike has become part of your body, responding instantly to your mind’s command.
So, what’s your vision of the perfect pedal assist? Shouldn’t it be smart enough to adapt to you?
Both flagship models—Blix Vika X and Blix Sol X—come equipped with torque sensors, AI smart chips, and the highly praised AUTO Mode.
