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 in this case, there is also no need for fuel, just recharging the electrical controller is enough. 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.
In winter, you especially want warmth and comfort. And a warm handmade blanket in this case is the best New Year’s gift!

Dilute fabric paints in water: each in a separate container. Dip white napkins into each container of paint one at a time. To get blurry patterns, you can start by twisting the napkins into a rope. And when finished, unfold it. If you want a smooth gradient pattern, dip only one end of the napkin. Or use a wide paint brush. Let the wipes dry. Wash and iron.
Arm training: extreme in 30 minutes, exercise technique, arm training program for the strong-willed.
There are few ways to better feel the load after training your arms, as there is after, but in order for the effectiveness to reach its maximum, it is necessary to reduce the duration of the workout.
It is provided for practical application here and now, this is a powerful engine that will make your arms increase in volume in just a 30-minute period of time.
1.Biceps Curls – 3 sets x 10 reps
Superset:
2. Dips – 3 sets x 10 reps
3. Narrow grip push-ups from the floor - 3 sets x 10 repetitions
Superset:
4. Incline Dumbbell Curls – 3 sets x 12 reps
5.Tate Press – 3 sets x 12 reps
6. Lifting the barbell on a Scott bench – 2 sets x 10 repetitions
7. Arm extensions on the upper block – 2 sets x 10 reps
This exercise is best done near a wall to eliminate inertial movements and body tilts back and forth. If during the exercise your forearms begin to “twist”, then you need to take an EZ bar, it will help relieve the load and more accurately feel the biceps.
First take a light weight for warming up, approximately 50% of the maximum, then choose so that you can clearly perform 10 repetitions without violating the technique.
First perform 10 repetitions with wide grip , after a rest of 45 seconds, bending the arms narrow grip for the same 10 repetitions, rest again for 45 seconds and the last 10 repetitions again with a wide grip.
These 2 exercises massively pump up the back muscles of the arms. First, perform 10 push-ups on the uneven bars without weights, paying careful attention so that the body does not lean forward, but is vertical, the elbows are fully straightened and close to the body.
After immediately without rest, perform 10 from the floor with a narrow position of the arms, make sure that the elbows are as close to the body as possible, inhale down, exhale up. Rest between supersets is also no more than 45 seconds.
This Double punch for the biceps and triceps, first perform curls on an inclined bench, in the starting position, the arms are fully straightened at the elbows and behind the body, when lifting the dumbbells, the elbows bend forward a little, at the top point try to strain the biceps as much as possible.
After immediately unfolding the gymnastic bench in a horizontal position, perform the Tate press, the elbows go strictly to the sides, and the dumbbells up; when lowering, they only lightly touch the chest, otherwise the load on the triceps will be removed for a short time, which reduces the effectiveness of the exercise.
The descent into Tate takes 2 times longer than the ascent. Rest between supersets is no more than 45 seconds.
A great option to finish off tired biceps. The training scheme has been improved; instead of the standard 3 working approaches, the following is performed:
Perform 2 sets of 10 reps, rest 45 seconds
The 3rd approach is done for 10 repetitions, then rest for 10 seconds and an additional 2-3 repetitions until failure, then drop 20% of the weight and perform in the style, then rest for 10 seconds and again - 25% of the weight, after this exercise is over.
The last exercise in a 30-minute arm workout, in order to eliminate and maximally work by isolating the triceps, extensions can be performed on your knees, as Jay Cutler, Mr. Olympia champion, did.
The training scheme is identical to the exercise on the Scott bench; at the end, your triceps will burn as if boiling water was poured on it.
Train smart and achieve the goals you want!
