In one of our previous articles, we discussed batteries and the role of microprocessors in making modern electric vehicles possible. One of our readers asked: “Is it true that thanks to electronics, your battery can last more than eight years?” The answer is yes. Battery life depends heavily on how it's charged and discharged, the speed and intensity of use, and the power demand at any given moment. But it's not just the battery as a whole that’s monitored — each individual cell is checked for its condition and level of wear. This data is collected every second and processed in real time to choose the optimal mode for every situation, whether you're charging, accelerating from a stop, overtaking, or just riding leisurely in the park.

Imagine speeding up at a traffic light, braking suddenly at an intersection, then slowing down because a squirrel jumps onto the road. Each action is unpredictable and requires instant reaction. If your e-bike hesitated for a few seconds before responding, it would be frustrating. These algorithms are programmed and executed in real time, handling massive amounts of data and variables. Electric motors add another layer of complexity — their speed and torque are controlled by adjusting electromagnetic fields, which means we need a dedicated controller. In the past, electric motors were used for simple tasks like lifting loads. The algorithm was straightforward. But with electric bikes, situations change constantly, requiring much smarter and faster control.

So, in our e-bike, there's a "smart" battery that communicates with a smart motor controller. Their interaction must be seamless, exchanging information and making decisions. The better this communication, the longer the battery and motor will last. But that's not all. To start moving, you might use a throttle or a PAS system. How fast do you want to go? Smoothly or with a burst of speed? Again, the bike needs to react instantly. It has to send the right signal to the battery, which delivers the necessary voltage to the motor without overheating or causing damage. That’s why the system is designed so precisely.

It’s important to understand that an electric bike isn’t just a regular bike with an engine attached. The difference is like that between a potter’s wheel and a 3D printer. Both can create beautiful objects, but a 3D printer opens up far more possibilities. Note that the diagram doesn’t show pedals — that’s key. A traditional bike relies on human power, while an electric bike uses stored energy from a battery, managed automatically by a processor. You can still pedal, but the effort remains consistent, and the motor supports you when needed — just like your smartphone or laptop. It’s a smart device on wheels, capable of doing more than just moving.

This means that features like GPS, anti-theft systems, and other smart functions are not just possible — they’re essential. All these systems can work together under one central control. For example, a GPS module could calculate a route and tell the system how fast you can move to ensure enough power for the entire trip. If the battery is low, it can suggest nearby charging points and estimate the time required. Integration with anti-theft and user identification systems makes the bike truly personalized. Even cameras, sensors, and communication modules can function as a unified system — something Tesla has already demonstrated.

So, why is Delfast considered a smart bike? Because it’s not just about power — it’s about intelligence, integration, and endless potential. And that’s exactly why it’s built for professionals. But that’s a story for the next article.
