Pedal-assisted bicycles, commonly called e-bikes, are revolutionizing the concept of urban mobility. Thanks to the presence of an electric motor that assists pedaling, e-bikes make it possible to travel long distances without fatigue and without polluting emissions. In this article we will analyze this new and environmentally friendly means of transportation in detail, highlighting its main advantages, how the integrated technology works, the different models available, legal and safety aspects, as well as practical tips for maintenance and use. We will also find out what impact electric bikes are having on urban traffic and users' lifestyles, including through real stories and experiences.

Le bicycles pedal-assisted bikes have many advantages, both practical and ecological. First of all, they allow longer trips, up to 50-70 km, with less physical effort. In fact, the electric motor complements human pedaling, making it easier and smoother. This allows even those who are not in top physical condition to use the bike on a daily basis. An additional benefit is the savings in fuel and parking costs compared to a car. In addition, e-bikes produce no harmful emissions, which benefits the environment. Finally, moving around by bicycle, including assisted bicycles, results in improved health and fitness.

Let's look in detail at how an e-bike is made and how it works from a technological point of view. The heart of the system is the electric motor, usually located at the bottom bracket level. It is powered by a battery, usually lithium-ion, located on the rear rack or integrated into the frame. Sensors, attached to the pedals or bottom bracket, detect when the cyclist starts pedaling and send this signal to the controller, which in turn activates the motor. The latter then kicks in, supplementing the cyclist's thrust with its own power.

When the cyclist stops pedaling or reaches the maximum allowable speed (25 km/h in Europe), the electric motor automatically turns off. The intensity and mode of assistance can be adjusted via a display or control unit mounted on the handlebars. Higher-end e-bikes can also connect to a smartphone app that allows customization of each parameter and analysis of ride data.

There are various models of e-bikes, designed to fit different needs. We find folding e-bikes, ideal for those who need portability on public transportation or due to space limitations. City e-bikes have low frames and narrower wheels, for easy disentanglement in urban traffic. For bumpy road surfaces and long out-of-town rides, e-MTBs are suitable, with wide knobby wheels and suspension. Trekking e-bikes make it possible to tackle long routes even with luggage thanks to their elevated position and rear rack. There are also models specifically for children or for loading goods.

One of the key elements of electric bikes is, of course, the rechargeable battery. The most popular models mount lithium-ion batteries, which are lightweight and have high energy density. Battery capacity is expressed in Wh (watt hours) and determines the range of the e-bike. Entry-level models offer 300-400 Wh and provide about 60 km of range. Top-of-the-line batteries go as high as 1000 Wh, giving a range of more than 150 km. The range also depends greatly on the level of assistance selected and the type of route. After depletion, the battery recharges in 4-6 hours by plugging it into the mains. It is important to store it properly, in a dry place and mild temperature, and never discharge it completely to preserve its longevity.

In Italy, e-bikes are equated with normal bicycles, so they do not require a license plate, license or insurance. However, there are regulations governing their characteristics. To be considered a pedal-assisted bicycle, the maximum power of the motor must be 250W and the supported speed must not exceed 25 km/h. Beyond these limits it is necessary to register the bike as a moped. It is mandatory to keep position lights on in low light conditions. There is also a requirement to wear a reflective vest at night outside built-up areas. Finally, e-bikes must ride on bicycle lanes where present and follow traffic regulations.

To function properly over time, electric bikes need periodic maintenance. It is important to frequently check the battery charge and clean any oxidation from the contacts. You must then check the functionality of the braking system, tire wear, and proper tightening of hardware. At least once a year it is advisable to have all electrical components checked at a specialized workshop to prevent any problems. Routine maintenance work, such as replacing brake pads or adjusting the transmission, is similar to regular bicycles.

E-bikes have advantages and disadvantages over traditional "muscle" bikes. The pros are greater effortless mileage, versatility of use, and lower pollutant emissions. The disadvantages are higher weight, higher costs, and the need to recharge batteries. Muscle bikes, on the other hand, require more physical effort but have lower costs and no electrical components to maintain. The choice therefore depends on one's needs. For many, the future of urban mobility will lie in a combination of the two types.

The rise in popularity of pedal-assisted bicycles can have positive impacts on urban mobility and quality of life in the city. Replacing the car with e-bikes for short trips, combined with an increase in bicycle lanes, would help to decongest vehicular traffic resulting in reduced smog and accidents. Administrations should therefore actively incentivize this environmentally friendly transportation solution, such as through purchase bonuses, parking discounts, or installation of battery charging stations. Large-scale promotion of electric bikes could really change the face of our cities.

The e-bike industry is undergoing great ferment and development. New models integrate more accurate pedaling sensors, feature-rich digital displays and geolocation systems. Future trends will include batteries with increasing range and reduced charging times. Electric motors will further improve, providing more natural pedaling assistance. There will also be no shortage of smartphone-integrated solutions for route analysis and anti-theft. Finally, the spread of torque sensor technology will make motor action proportional to the cyclist's effort.

But what is the real impact of the spread of pedal-assisted bicycles? We gather here some direct testimonials from users about their experiences of use. Mario, a 45-year-old office worker, recounts, "Since I have the e-bike I go to the office without stress, I don't sweat when I arrive, and parking is easy. I feel more fit and I save money every month on gasoline and car box." Anna, 35, says, "I take it instead of public transportation, environmentally friendly and low cost. I can go anywhere without getting tired." Marco, an out-of-town university student: "I reach the faculty in a few minutes without traffic or parking problems. And thanks to the engine I effortlessly overcome all the climbs." These are just a few of the many testimonies of how pedal-assisted bicycles are positively changing people's mobility and lives.

E-bikes represent one of the most exciting trends in sustainable urban mobility. The environmental and practical benefits are undeniable: zero emissions, reduced traffic, ease of parking, improved health. Technology to support human pedaling has reached impressive levels. With the continued development of batteries, motors and sensors, e-bikes are set to carve out an increasingly crucial role for themselves in the context of modern mobility. It is now up to local governments to promote and incentivize this clean, cheap and efficient transportation solution to relieve congestion in our cities.
