Chinese Startup Develops Light And Compact Kit That Converts Regular Bicycles Into Electric Bikes In Minutes, With High-Power Motor, Removable Battery And Up To 90 Km Of Autonomy, Focused On Sustainable Urban Mobility.
A Chinese startup formed by former engineers from BYD and Huawei has presented a compact kit that promises to facilitate the adoption of electric mobility.
Called Kamingo, the equipment weighs about 900 grams and can be installed in approximately three minutes, according to the manufacturer.
The system was developed to convert conventional bicycles into electric models without the need for tools or structural modifications.

There is a hidden city 30 meters below the streets of Springfield, in the United States, where 700 trucks disappear into the ground every day and thousands of tons of food are stored at a natural 17°C without spending a watt on refrigeration.
According to the company, the motor has dimensions close to that of the palm of a hand, but achieves a maximum power of 750 W and torque of 40 Nm.
The performance is achieved through friction drive, where the motor is coupled to the frame and acts directly on the rear wheel.
The setup allows speeds of up to 32 km/h, a limit compatible with regulations for electric bicycles in various countries.
The kit includes a removable battery weighing 1.4 kg, designed similarly to a water bottle.
The component can be fitted into the standard frame holder and, according to the company, offers a range of up to 90 km, varying based on terrain and riding mode.
Charging occurs through conventional outlets, allowing use in domestic and commercial environments without additional equipment.
Installation And Usage Modes
The assembly process is one of the distinguishing features highlighted by the startup.
The system is modular and intuitive, allowing for the fitting of parts without specific tools.
The proposal is for the cyclist to be able to adapt the kit and remove it quickly, facilitating transport or use on different bicycles.
The electronic control is installed on the handlebars and features a color screen that displays information on speed, distance traveled, and battery level.
There are three operation modes: standby mode, where the bicycle operates without electrical assistance; assistance mode, which reduces the cyclist’s physical effort; and cruise mode, which propels the bicycle without pedaling, respecting the legal speed limit.
According to the responsible company, the system was designed to provide stability and immediate response, maintaining control during acceleration and braking.
Mobility experts consulted by local vehicles state that this type of technology is likely to popularize the use of electric bicycles, especially due to the simplicity of installation.
Friction Drive And Technical Limitations
The Kamingo uses a friction drive method, which transmits the motor’s movement directly to the rear tire.
This format eliminates the need to alter hubs, wheels, or axles, which according to the developer, expands compatibility with different bicycle models.
On the other hand, industry technicians point out that the efficiency of this type of system can vary in rain or humidity conditions, as the friction with the tire depends on the adherence between surfaces.
There is also the possibility of greater tire wear over the long term, depending on the intensity of use and calibration.
The startup indicates that the product has automatic pressure adjustment and disengagement mechanisms to reduce friction when the motor is not in use.
Bottle-Shaped Battery
The battery model, with a design similar to that of a water bottle, was chosen to utilize the standard bottle holder already present on most bicycles.
This solution distributes weight in the center of the frame and avoids structural modifications.
According to the manufacturer, range of up to 90 km is achieved under ideal conditions of flat terrain and moderate assistance mode.
Electric bicycle experts note that, in common urban routes, the actual range tends to be lower, which is still considered sufficient for daily short and medium-distance commutes.
The charging can be done directly on the removed battery, connected to a conventional outlet.
The total charging time has not been officially disclosed by the company so far.
Power And Urban Performance
With 750 W of maximum power and 40 Nm of torque, the Kamingo falls within the performance range observed in conversion kits for urban use.
The system was designed to maintain constant speed and assist in gentle climbs, according to the startup’s specifications.
The limit of 32 km/h complies with current safety regulations for electric bicycles in several countries, although the regulation may vary between regions.
In standby mode, the company claims that the motor offers no perceptible resistance, allowing the bicycle to be used as a conventional model.
Digital Panel And Mode Control
The color panel installed on the handlebars displays indicators for speed, distance, and remaining energy, as well as allowing switching between usage modes.
The assistance mode provides additional boost when pedaling.
The cruise mode activates the motor automatically without pedaling.
And the standby mode completely disables the system.
According to the startup, the goal is to provide an experience adjustable to different user profiles, from recreational cyclists to workers who use the bicycle for short trips.
Expansion And Mobility Market
The proposal of the Kamingo follows the trend of portable and lightweight solutions in the electric bicycle market.
Urban mobility specialists evaluate that reducing the cost and complexity of conversion can widen access to technology, especially in countries where the price of complete e-bikes is still high.
The company has not disclosed, so far, the sale price or the markets where the product will be available.
There is also no information about security certifications or plans for launch outside of China.
Industry analysts state that the simplicity of assembly and low weight are factors that can attract cyclists interested in trying electric technology without giving up the bicycle they already own.
However, they note that the actual performance depends on variables such as tire type, calibration, and weather conditions.
As the supply of conversion kits expands and lithium-ion battery technology advances, experts believe that products like the Kamingo may represent an intermediate step between traditional bicycles and complete electric models.
Although the initial performance is promising, it remains to be seen how the equipment will perform in prolonged use, heavy rain conditions, and uneven pavements, aspects that often determine the durability and viability of such products.
The growing interest in compact solutions indicates a shift in commuting habits.
Rapaz, no final não tem notícia nenhuma só embromação.
Perdi 5 minutos de vida com essa reportagem que não disse nada
Nossa!!! Como essa internet tá cheia de pseudos jornalistas, são reportagens sem pé e nem cabeça.
Nem mais leio, a grande maioria são horrorosas!!!!!
Realmente esta internait é mais um passa tempo só quando a gente não tem nada pra fazer ne?
Até já puseram até que um moléque aqui em Franco da Rócha consegue ganhar ou robar 32.000mil reais por dia. mais do que um presidente da republica emmmmm
Inacreditável tais mentiras como estas não é?
Eu moro aqui em Franco da Rócha já 20 anos e ainda não consegui encontrar este **** debaixo do chão cavando não se encontra este **** emmmm
🤣🤣🤣🤣
Onde esta internait quér chegar emmmm🤣🤣🤣🤣🤣🤣
