The video provides a detailed guide on how to build a homemade electric bicycle that can reach speeds of up to 60 km/h, cover distances of up to 100 km, and is significantly cheaper than market alternatives. The process involves adapting a normal bike with an electric engine and components, which are relatively inexpensive compared to commercial options.
The video begins by emphasizing the cost-effectiveness of the project, noting that a similar product in the market can cost thousands of euros. The video's creator used a bike with a gasoline engine, which he modified to increase power and reduce noise. He also mentions a previous electric bicycle project, but it was not related to the one being discussed.
The video then provides advice on choosing a suitable bike frame and engine. The frame should be sturdy and able to withstand the pressure of the electric motor. The video's creator recommends a steel frame with simple tubes for their durability and affordability. The engine should be installed in the rear wheel for better wheel grip. The video's creator suggests buying an already assembled engine kit for ease of installation.
The video also discusses the importance of choosing the right batteries. The video's creator recommends li-ion batteries for their reliability and power. The batteries can be bought raw or with a plastic casing. The video's creator also explains the difference between amps (capacity) and voltage (power), emphasizing that combining two cells with the same amps will double the voltage, not the duration.
The video then walks through the assembly process, which involves removing the rear wheel, installing the new wheel, and connecting the wheel's cable to the controller. The video's creator also explains how to install the battery and controller in the frame, and how to adjust the brake. The video concludes with a discussion on the reliability of the electric bicycle, noting that it can last up to 10,000 km with proper care.
The video also provides recommendations for other electric bikes, suggesting alternatives to the QiCycle due to its high price. The video's creator recommends the basic model of the Xiaomi scooter and another bike model with two disc brakes and a 48v battery. The video concludes with a note of satisfaction and a promise to see the viewer again.
