With the introduction of laws and regulations on electric bikes, many riders’ vehicles are restricted or require rectification. And a type of e-bike that is not restricted comes to people’s mind which is pedal charging e-bike.
Definition of pedal charging e-bike
From this name alone, people can have a general understanding of this type of bicycle called pedal charging e-bike. Pedal charging e-bikes can convert kinetic energy into electrical energy by riding to generate electricity, which helps accelerate the e-bike speed and transform traditional bicycles into electric bicycles.
Its characteristics are energy conservation and environmental protection, adhering to the concept of green travel, approaching zero emissions, and protecting the environment.
How does the pedal charging e-bike work
There are currently two types of pedal charging e-bikes on the market.
One type is that the bicycle wheel is equipped with a power generation device. For example, a shared bicycle has chainless transmission on its wheels, and a power generation device integrated into the rear wheel hub drives the relative displacement of the internal magnetic module through the rolling axle during riding. Using the principle of magnetic electricity generation, the rider works to generate electricity.
Afterwards, in order to ensure the stability and reliability of the bicycle intelligent lock, optimize the speed and user experience of the bicycle, the shared bicycle company improved its power generation device, no longer using a transmission device, but assembling a bike chain and a bike chainring like a regular bicycle. Abandoning the design of the built-in power generation drum, it was replaced by a solar panel installed in the car basket.
Riding is also more lightweight and effortless.
The second type is hydrogen powered bicycles. The working principle of a hydrogen bicycle is to add a hydrogen generator and hydrogen storage device on the basis of a regular bicycle. Just like an electric vehicle with a battery, the hydrogen generator in a hydrogen bicycle, as a fuel cell, can generate kinetic energy through the electrochemical reaction of the built-in hydrogen generator.
The market of pedal charging e-bike
At present, in the market there are few electric bicycles which e-bike drive system rely solely on pedaling for power generation. Let’s take a look at the following possible reasons for this situation.
The experience of riders
At the beginning of the e-bike, which drives the generator to operate, riders may feel struggling. When the speed starts to increase, they can hear a buzzing sound from the rear drum, which is the sound of the generator’s electric brush. However, this design does not provide a good riding experience for users, as the wheels feel heavy to press and it can be very difficult to start.
The hydrogen bicycle has a better riding experience, although it still requires pedaling, but the riding speed is much faster than a bicycle, with a maximum speed of 23km/hour. In contrast, the maximum speed of an electric bike is 25km/hour. Hydrogen bicycles are almost unaffected by external temperature, and can output normally and stably in both summer and winter, with almost no difference in range.
But the hydrogen bicycle, which looks no different from a bicycle but is actually much faster than a bicycle, currently has a market price of 12000 yuan. From the perspective of cost-effectiveness, it seems unnecessary to buy a hydrogen bike that requires pedals and has a speed similar to an electric bike. After all, the price of buying a hydrogen bike is about enough to buy three ordinary electric bikes.
The technology of pedal charging e-bike
The hydrogen bicycle industry is still in the exploratory stage, and many projects are pilot or demonstration projects.
The e-bike technology that drives the operation of electric motors through cycling mainly generates electricity in the following three forms.
The first type is frictional power generation, using bicycle tires to generate electricity through friction. When riding, the resistance increases too much. Only by riding can the bicycle generate electricity, and the kinetic energy ultimately comes from the legs. Only when riding at high speeds can the electric motor provide assistance.
The second type of flower drum power generation is the same, and the problem of resistance has not been overcome. The third principle of magnetic induction is used for power generation, but it is not widely applied in the market at present, which proves that the technology is not yet popularized and is still improving.
The common technology for charging bicycles now belongs to the function of assisting bicycle riding, mainly through electric motor power generation. Some bicycles are equipped with innovative energy recovery technology and are equipped with a reverse charging system for cycling, which allows for charging even when riding on foot. In addition, electric bikes can also recover energy while sliding on flat or downhill surfaces, allowing for charging while riding and increasing the e-bike range.
The use of pedal charging e-bike
The pedal charging technology on the market is usually used on spinning bikes, which converts the kinetic energy generated by cycling into electricity to charge their electronic devices.
The latest type of pedal charging e-bike adopts a smooth magnetic plate design, effectively reducing the noise during cycling, and can adjust the resistance gear. Users can choose whether to use a low resistance mode for easy warm-up or a high-intensity training mode for challenging the limits, making each ride more efficient and personalized.
Its self generating technology, silent design, and convenient operation have become an ideal choice for home fitness, but currently this technology is only available on home exercise and fitness equipment.
Conclusion
This article provides a general overview of the definition, operational mode, consumer experience, and technological level of pedal charging e-bikes, as well as the application of common pedal charging technologies in spinning bikes.
At present, this type of bicycle has not yet become a popular trend. In the future, with the continuous advancement of technology, the popularity of hydrogen bicycles and other pedal charging e-bikes will definitely increase in order to practice green transportation. However, whether they can become the main trend of urban transportation in the future may require a long time of precipitation and development.
