In one of our previous posts, we discussed the role of batteries and how they are essential for modern electric vehicles. Without the development of microprocessors, it would be nearly impossible to create today’s advanced e-bikes. One of our readers asked in the comments: “Is it really true that your battery can last more than eight years thanks to electronics?” The answer is yes. Battery life depends on many factors — the way it's charged and discharged, the speed, intensity, and the current required at any moment. But it's not just the battery as a whole that's monitored — each individual cell is checked and compared against others. This data is processed every second, allowing the system to choose the optimal performance mode based on the situation. Whether you're charging, accelerating from a stop, overtaking, or riding leisurely in the park, everything is carefully managed.

Imagine speeding up at a red light, braking suddenly at an intersection, then gliding into the park only to slow down because of a squirrel crossing the road. These unpredictable moments require real-time responses. Picture this: you twist the throttle, but nothing happens — the bike hesitates for a few seconds before slowly moving. That would be frustrating. All these decisions are made through pre-programmed algorithms that process data instantly. Think about the amount of information and variables involved. It's no simple task.

Electric motors add another layer of complexity. Their speed and torque are controlled by adjusting the electromagnetic field in the windings. That means, to manage the motor effectively, we need a controller. In the past, electric motors were used for predictable tasks like lifting loads with known weights and speeds. But with e-bikes, situations change constantly — sudden accelerations, stops, and varied terrain. That’s why smart, fast control is essential.

Now you see that our e-bike has a "smart" battery that communicates with a "smart" motor controller. At some level, they must understand each other, exchange data, make decisions, and adapt. The better this communication, the longer the battery and motor will last. And that’s not all. To start moving, you use a throttle or a PAS system. How do you know how fast you want to go? Smoothly or with a burst of power that makes the tires smoke? Remember the squirrel example? Your bike needs to detect that instantly, send a signal to the battery, which then supplies the right voltage to the motor — without overheating or causing damage.

The image of an e-bike as just a regular bike with an electric motor attached is outdated. Yes, it performs similar functions, but the difference is like comparing a potter’s wheel to a 3D printer. Both can make beautiful bowls, but the 3D printer can handle much more complex tasks. Also, notice there are no pedals in the block diagram. That’s important. An e-bike moves using stored energy from a battery, controlled automatically by a processor. Of course, you can pedal all the way, but the engine will assist you smoothly, making your ride effortless whether you're going straight or climbing a hill.

This is the same principle as your smartphone or laptop — a smart electronic device, just on wheels. That means any function that works on a phone can potentially be implemented on an e-bike. For instance, GPS, anti-theft systems, sensors, cameras, and even cloud connectivity. These components communicate through a bus, allowing for endless integration possibilities.

Because all systems in a modern e-bike should work together under one central control. A GPS module can calculate a route and tell the processor how fast you can go to ensure enough battery for the entire trip. If the charge is low, the GPS can suggest where to recharge and estimate the time needed. We can also track the bike’s location and link it to an anti-theft system. In turn, the anti-theft system can be tied to user identification, making the bike truly personal. A media center, temperature sensors, radar, cameras, and communication modules can all work together. Tesla shows what’s possible — and it’s achievable on any e-bike with the right investment.

But the main point is that e-bikes, like all electric vehicles, are already part of the modern world. They fit seamlessly into daily life and offer endless potential for future development. So, why is Delfast a professional-grade e-bike? That’s the topic of our next article.
