How to assemble the electric bike with your hands in 30 minutes?

Today we tell, is it realistic to make electric bike for 30 minutes. The popularity of this safe, compact and easy mode of transport is increasing continuously. The algorithm is nothing complicated described below. We pay special attention to the option of creating a folding structure. Such a tool will serve for many years in the case if you follow safety measures.

Advantages

Experts say that if you use ready-made kit for electric bicycles, the assembly for 30 minutes it is possible to be smart enough. Such a vehicle has many advantages. It may be convenient to move around the city, where there is a lot of traffic jams. To such means are not required right.

In this case, in the fuel and there is no need, just enough to recharge elektrokontrollera. Such a solution helps to maintain in its owner's fitness because it uses muscle power.

It should also be noted that the electric bike can be done at home with their own hands, thus not depend on market prices and stores. Average unit can reach 42 kilometers per hour. Weight around 35 kg.

Make transport

Collect electric bike for 30 minutes - the reality even for a schoolboy. But before you start to collect the model, you should decide how the result should look like and what kind of tasks will be assigned to this transport. You can buy a special kit for the assembly of electric bicycles. This approach greatly simplifies the job.

However, the most essential element stands alone unit, which should have a thicker frame. On it we have to install the motor. Find the necessary parts and components can be on the technical direction of the market, in special shops for inventors on sales.

Main components

We need the engine at 48 volts, bike, able to withstand it. In addition, it will go a number of fasteners and tools. As well as resourcefulness.

Also required:

to

• for fixing the motor made of stainless steel;
• fuses;
• switches;
• "star" on the 66 and 13 teeth;
• moped chain;
• disc brake rotor type (2 pieces);
• acid batteries for starting the power supply system;
• a special controller, equipped with a programmable control.

Next, modify the brake and wheel fork. Electric bike with his hands for 30 minutes to collect as possible, but should start with the front fork. Then set the engine, battery, resistor. Yourselfers prefer to make a folding bike.

Such means may in a few seconds to become a commercial embodiment, either fit in the trunk. Demountable embodiment in many respects may be considered more convenient, for example, ease of transporting the lift and the reduced size of the wheels. The essence of the modification can be reduced to the frame cutting.

To it should weld connecting the nodes in the two places. They are fixed by means of special bolts, screws and wing nuts. Procedure for the disassembly of the unit takes about one to two minutes.

Motor Selection

If you decide to collect the electric bike with his hands for 30 minutes, it should be remembered that such a means requires appropriate technical add-ons. This will ease the muscular effort. The engine is the main structural member. It should be selected according to the required amperage and voltage. The power should be about 400 watts, in this case it will be possible to achieve a speed of 30 km per hour, provided that the gearbox. Trip distance is also within thirty kilometers. However, the latter figure depends on the battery capacity.

Before selecting a model should take into account the balance between capacity and the battery voltage, as well as relevant indicators of the engine. Consider this relationship as an example. When using a motor 12 volts and 500 watts, needed a battery that has a capacity of forty amperes per hour. Permitted indicator can be calculated by Ohm's law.

With good battery discharge level can last longer. To save energy, it is advisable to accelerate the muscle power, you will need to stand on the pedals. This approach will save energy in the coefficient exponent 1 and 2. It is better to consume charge during movement to more complex road segments. For example, the path can pass through the dirt road, slides and hills.

Set up resistor

To assemble the electric bike with his hands for 30 minutes, you should take care of special handles gas. Variable resistor option allows you to manage the number of turns of the engine and speed change. You must first calculate the AC power, and then use the appropriate instrument with the required voltage.

Brake lever set for opening the contacts. The position they are always closed and transmits electricity through the circuit. Pressing the contacts provides circuit and open circuit - motor accelerates or stops. Standard kit typically contains parts necessary for assembly. Master task - to collect them so that when you press the brake lever on the engine stopped. To do this, use two pieces of aluminum. One set on the moving elements of the brake, and the second to those who are at rest.

By welding in this combination we connect circuit in the engine. To do this, we use brackets. This solution provides a functional design electric brake.

The final touch

In order to design electric bike with his hands for 30 minutes, require knowledge of several laws of physics. For example, the conductivity of different materials and strength of materials. It is also useful to Ohm's law.

When properly designing can see beforehand in the spaces created by the design and identify the causes of possible failure or possibilities for subsequent modification. The structure of an electric bike includes the following elements: a housing, a power source, a battery, a variable resistor engine.
