Electric bike with their own hands for 30 minutes. Self-made electric bike

The popularity of such a compact, light and safe mode of transport, like a folding electric bike, grows from year to year. How to make such a design with your own hands to save on buying?

Benefits

Experts say that to make a fashionable and sturdy construction there is a little witty enough to buy the relevant parts - and the faithful electric horse is ready. It has a lot of advantages:

• On such transport it is possible to move perfectly around the city, full of traffic jams;
• It does not require a driver's license;
• Do not need fuel, only recharging for the electrical controller;
• It helps maintain a sporty shape thanks to the muscular force used;
• Made self-made electric bicycle helps to be independent of stores and market prices.

The average unit achieves speeds of up to 42 kilometers per hour, and cruising at 26 kilometers per hour. The weight of the whole device will be up to 35 kilograms. To make a high-quality and reliable model from the available materials, it is worth using the recommendations of experienced masters.

We make wheeled transport ourselves

How does the assembly of the whole model begin? To begin with, it is necessary to decide how the result should look and what goals we want to achieve with the help of this transport. You can buy a special set for electric bike - it greatly simplifies all the work on the assembly. But the most important thing is that it is necessary - this is actually the unit itself with a thickened frame, on which you can put an electric pick.

Find the necessary details and accessories can be on sales, in stores for inventors, in markets with technical goods. Electro-bike with their own hands for 30 minutes to gather quite the forces of an advanced student.

Main Components

Usually you need a 48 volt engine, a strong bike that will withstand it, a few tools and bindings. And also patience and resourcefulness, readiness for technical testing.

Additionally, you will need:

• A special controller with programmable control;
• Acid batteries for the power system;
• Disc brake (2 pcs.) Rotor type, mechanical;
• Moped chain;
• "Asterisk" on 13 and on 66 teeth;
• Switches;
• circuit breakers;
• Fastenings for the engine from a stainless steel.

Then the wheel fork and brakes are modified. Electro-bike with their own hands for 30 minutes begin to collect from the front fork. Then the engine, the accumulator, the resistor are built up.

Some craftsmen prefer to assemble a folding bicycle, which in seconds can turn from ordinary to cargo or fit in the trunk. Collapsible option is convenient for a variety of reasons - reduced wheel size, ease of transportation in the elevator. The essence of the modification consists in cutting the frame, to which the connecting nodes are welded in two places. They are fixed with special bolts, screws and lug nuts. The procedure of assembly and disassembly of the unit in everyday life takes less than 1-2 minutes.

Engine Selection

A self-made electric bike requires the establishment of an appropriate technical superstructure that will facilitate muscular efforts. The main element of the entire design is the engine. It is selected in accordance with the required voltage and current. At the same time, the received power should be in the region of 400 watts, then it will be possible to reach a speed of up to 30 kilometers per hour in the presence of a reducer. The range of the trip can also reach 30 kilometers, depending on the capacity of the battery.

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, if you select an engine of 500 watts and 12 volts, you need a battery with a capacity of 40 amperes per hour. The permissible capacity is calculated according to Ohm's law. At a normal discharge level, the battery will last longer and more reliable. To save energy, it is better to accelerate muscular strength, standing on the pedals - this will save energy at the level of 1.2. It is better to spend a charge on more difficult sites during the movement: on hills and hills, dirt road.

Resistor setting

An electric three-wheeled adult or two-wheeled electric car equally requires the presence of gas handles. Variable version of the resistor helps to control the change of speeds and the number of engine speed. Calculating the power of an alternating current, take the appropriate device with the desired voltage. On the brake handle, the contacts for opening are set-their position is always closed, passes electricity through the circuit. Pressing the contacts opens and closes the circuit - the motor stops or accelerates the operation.

Typically, a standard electric bicycle kit contains the necessary parts for assembly. The master's task is to make the engine stop at the pressure on the brake knob. To do this, take two aluminum slices. One is installed on the moving parts of the brakes, the second - on the stationary ones. The connection of this combination to the break in the motor circuit, which is attached to the brackets by welding, gives a functional electric brake.

Schema development

To assemble an electric bicycle with your own hands in 30 minutes, you need a minimum of skills, but you must know some of the laws of physics. For example, Ohm's law, the resistance of materials or the electrical conductivity of different substances. Having created a simple scheme in accordance with the classical technical requirements, you can clearly see the gaps in the design, the reasons for possible malfunctions or the possibility for further modification.

The electric bicycle scheme includes the following elements:

• Bicycle body;
• Current source;
• engine;
• Variable resistor for insertion into a circuit break;
• Battery.

Different schemes allow to improve the invention and accelerate the transport to higher speeds with the same battery.

Choosing a controller

The main difference between the classic vehicle and the electrified vehicle is the presence of a special regulating device. This is a controller for electric bike, which is a box that manipulates the thrust of the whole unit. If the country has a restriction on the speed of movement on a bicycle, this device will help establish a limit while driving. Most often this is 25 kilometers per hour.

The design of such a sensor does not include an electric brush. But there is a processor that tracks the position of the wheel rim magnets. The controller allows you to optimally distribute the load on the wheels, reduce the release of heat, and the engine - to normalize the effort to move without jerking. The developed algorithms of motion help to move evenly and with the same speed.

Rules of operation

Today you can see with your own eyes enough vehicles collected by craftsmen. They are climbed by mountain climbing, dangerous stunts, conquering gorges. But you can just enjoy a good reliable car, which got a second wind thanks to the engine.

It is important to comply with the technology of manufacturing an electric bike with your own hands for 30 minutes, but no less carefully you need to take into account the recommendations for the correct use of this vehicle. You can not constantly overexert the battery beyond the set speed in the engine. Also, the bicycle should not be placed in the sun - the battery can overheat and lose capacity by 80% of the original volume. Especially dangerous are temperatures around 40-45 degrees in hot countries.

Electro-bike with their own hands for 30 minutes to collect can be quite high quality. It will last for many years, if you follow security measures and correctly follow all recommendations.

So, we figured out how to make a self-made folding electric bike. As you can see, there is nothing complicated in this.
