Today we will tell you whether it is possible to make an electric bicycle in 30 minutes. The popularity of this safe, compact and lightweight type of transport is constantly growing. There is nothing complicated in the algorithm described below. We will reverse Special attention for the option of creating a folding structure. This product will last for many years if you follow safety precautions.
Experts say that if you use a ready-made kit for an electric bicycle, assembly in 30 minutes is quite possible, just be smart. Such a vehicle has many advantages. It allows you to conveniently move around the city, which has a lot of traffic jams. No rights are required for such a tool.
In this case, there is also no need for fuel; only recharging the electrical controller is sufficient. This solution helps keep its owner fit, as it uses muscular strength.
It should also be noted that you can make an electric bicycle at home, with your own hands, thereby not depending on market prices and shops. The average unit can reach 42 km per hour. Weight will be about 35 kg.
Assembling an electric bicycle in 30 minutes is a reality even for a schoolchild. But before you start assembling the model, you should decide what the result should look like and what specific tasks will be assigned to this transport. You can purchase a special kit for assembling an electric bicycle. This approach will greatly simplify all the work.
However, the most necessary element is the unit itself, which must have a thicker frame. We have to install an electric motor on it. You can find the necessary components and parts in technical markets, in special stores for inventors, and at sales.
We'll need a 48 volt motor and a bike that can handle it. In addition, a number of fasteners and tools will be used. And also resourcefulness.
Additionally you will need:
Next, modifications are made to the brakes and wheel fork. You can assemble an electric bicycle with your own hands in 30 minutes, but you should start with the front fork. After this we install the motor, battery, resistor. Craftsmen prefer to make a folding bicycle.
In a matter of seconds, such a vehicle can turn into a cargo version or fit in the trunk. Collapsible option can be considered more convenient in many ways, for example, ease of transportation in an elevator and reduced wheel size. The essence of the modification can be reduced to cutting the frame.
The connecting nodes should be welded to it in two places. They are secured using special bolts, screws and wing nuts. The unit disassembly procedure takes from one to two minutes.
If you decide to assemble an electric bicycle with your own hands in 30 minutes, you should remember that such a product requires an appropriate technical add-on. This will ease muscle effort. The engine is the main structural element. It should be selected according to the required current and voltage.
In this case, the power should be about 400 watts, in which case it will be possible to reach a speed of 30 km per hour, subject to the presence of a gearbox. The travel range is also within thirty kilometers. However, the latter indicator depends on the battery power.
Before choosing a model, you should consider the balance between battery capacity and voltage, as well as the corresponding engine performance. Let's look at this dependence with an example. If you use a 12-volt, 500-watt motor, you need a battery that has a capacity of forty amperes per hour. The permissible indicator can be calculated using Ohm's law.
At good level discharge, the battery may last longer. To save energy, it is advisable to accelerate with muscular force, while you need to stand on the pedals. This approach will save energy by a factor of 1.2. It is better to use up the charge while traveling on more difficult sections of the road. For example, the path may go through dirt road, slides and hills.
To assemble an electric bicycle with your own hands in 30 minutes, you should take care of special gas handles. The variable resistor option makes it possible to control the number of engine revolutions and speed changes. You must first calculate the power alternating current, and then use the appropriate device with the required voltage.
Opening contacts are installed on the brake handle. Their position is always closed and allows electricity to flow through the circuit. Pressing the contacts closes and opens the circuit - the engine speeds up or stops. A standard kit usually contains the parts necessary for assembly.
The master’s task is to assemble them in such a way that the engine stops when you press the brake handle. To do this, use two aluminum pieces. We install one on the moving elements of the brakes, and the second on those that are at rest.
By welding, we connect this combination to the open circuit in the engine. For this we use brackets. This solution will provide the design with a functional electric brake.
To design an electric bicycle with your own hands in 30 minutes, you will need knowledge of several laws of physics. For example, electrical conductivity various substances and resistance of materials. Ohm's law will also come in handy.
With proper design, you can see in advance the gaps in the design being created, as well as determine the causes of possible problems or opportunities for subsequent modification. The structure of an electric bicycle includes the following elements: body, battery, variable resistor, motor.

The popularity of such a compact, lightweight and safe form of transport as a folding electric bicycle is growing from year to year. How to make such a design with your own hands to save on purchases?
Experts say that to make a fashionable and durable design, all you need is a little ingenuity, buy the appropriate parts - and your faithful electric horse is ready. It has many advantages:
The average unit reaches speeds of up to 42 kilometers per hour, and at cruising speed it goes at 26 kilometers per hour.
The weight of the entire device will be up to 35 kilograms. To produce a high-quality and reliable model from available materials, it is worth using the recommendations of experienced craftsmen.
Where does the assembly of the entire model begin? First, we need to decide what the result should look like and what goals we want to achieve with the help of this transport. You can buy a special kit for an electric bicycle - it greatly simplifies the entire assembly work. But the most important thing that is needed is the unit itself with a thicker frame on which an electric motor can be installed.
Find necessary details and components can be found at sales, in stores for inventors, in markets with technical goods. An advanced student can easily assemble an electric bicycle with his own hands in 30 minutes.
Typically you need a 48-volt motor, a sturdy bike that can handle it, and some tools and mounts. As well as patience and resourcefulness, readiness for technical tests.
Additionally you will need:
Some craftsmen prefer to assemble a folding bicycle, which in seconds can turn from a regular one into a cargo bike or fit in the trunk. The collapsible version is convenient for many reasons - reduced wheel size, ease of transportation in an elevator.
The essence of the modification is to cut the frame, to which connecting units are welded in two places. They are fixed with special bolts, screws and the procedure for assembling and disassembling the unit at home takes less than 1-2 minutes.
A homemade electric bicycle requires the installation of an appropriate technical superstructure that will facilitate muscular efforts. The main element of the entire structure is the engine. It is selected according to the desired voltage and current. In this case, the resulting power should be around 400 watts, then it will be possible to reach speeds of up to 30 kilometers per hour with a gearbox. The travel range can also reach 30 kilometers, depending on the battery power.
Before choosing a model, it is important to consider the balance between the voltage and capacity of the battery and the voltage and capacity of the engine. For example, when choosing a 500-watt, 12-volt motor, you need a battery with a capacity of 40 amperes per hour. The permissible capacity is calculated according to Ohm's law. At normal level discharge, the battery will last longer and be more reliable. To save energy, it is better to accelerate with muscle power while standing on the pedals - this will save energy by a factor of 1.2. It is better to spend the charge on more difficult areas while moving: hills and slides, dirt roads.
A three-wheeled adult or two-wheeled electric bicycle equally requires the presence of throttle grips. The variable resistor option helps control the speed change and the number of engine revolutions. Having calculated the AC power, take the appropriate device with the required voltage. Opening contacts are installed on the brake handle - their position is always closed, allowing electricity to pass through the circuit. Pressing the contacts opens and closes the circuit - the engine stops or accelerates.
Typically, a standard e-bike kit contains the necessary parts for assembly. The master's task is to make sure that the engine stops when pressure is applied to the brake handle. To do this, take two aluminum pieces. One is installed on the moving parts of the brakes, the second on the stationary parts. Connecting this combination to the open circuit of the motor, which is attached to the brackets by welding, provides a functional electric brake.
To assemble an electric bicycle with your own hands in 30 minutes, you need a minimum of skills, but knowledge of some laws of physics is required.
For example, Ohm's law, resistance of materials or electrical conductivity of various substances. Having compiled simple diagram in accordance with classical technical requirements, you can clearly see gaps in the design, causes of possible problems or opportunities for further modification.
The electric bicycle circuit includes the following elements:
Different schemes make it possible to improve the invention and accelerate vehicles to higher speeds using the same battery.
The main difference between a classic vehicle and an electrified one is the presence of a special control device. This is a controller for an electric bicycle, which is a box that manipulates the traction of the entire unit. If your country has a speed limit for cycling, this device will help you set the limit while riding. Most often it is 25 kilometers per hour.
The design of such a sensor does not include electric brushes.
But there is a processor that monitors the position of the wheel rim magnets. The controller allows you to optimally distribute the load on the wheels, reduce heat generation, and allow the engine to normalize the effort of moving without jerking.
Developed movement algorithms help you move evenly and at the same speed.
Today you can see with your own eyes quite a few vehicles assembled by craftsmen. They perform mountain climbs, dangerous stunts, and conquer gorges. But you can just enjoy a good reliable car, which received a second wind thanks to the engine.
It is important to follow the technology for making an electric bicycle with your own hands in 30 minutes, but you need to pay no less attention to the recommendations for correct use this means of transportation.
You cannot constantly overstress the battery by exceeding the set speed in the engine. Also, the bike should not be placed in the sun - the battery may overheat and lose capacity by 80% of its original volume. Temperatures around 40-45 degrees are especially dangerous in hot countries.
You can assemble an electric bicycle with your own hands in 30 minutes with sufficient quality. It will last for many years if you follow safety precautions and correctly follow all recommendations.
So, we figured out how to make a homemade folding electric bike. As you can see, there is nothing complicated about this.
