Let's watch some short videos.
Tools and materials:
-Engine included; -Chain and sprocket; -Voltmeter/ammeter; -LED strip;
-Accumulators (batteries from an old electric bike);
-Various metal materials;
-Seat from an exercise bike;
Step one: frame
In this homemade product, a ready-made go-kart frame is used. The frame is old and some parts are already rusted. Engine, pedals, cable, etc. were dismantled. The frame is free of dirt and rust.
Step two: seat
The kart had a seat, but it was metal and in a rather poor condition … Riding on a metal seat, in a vehicle without a suspension, is still a pleasure. It was decided to install an exercise bike seat on the kart.
The seat has been removed.
Part of the frame is cut out.
Then the parts were adapted for attachment to karting.
Step three: painting
The frame was painted yellow.
Step four: battery
The card uses 5.5 A/h 3.6 V lithium-ion batteries. The batteries are not new, they have already traveled about 5000 km on an electric bike.
Installing batteries in series ( 12) -parallel (3).
To install batteries makes a box of plywood.
Paints it and installs it on the maps.
Step five: the gas pedal
The gas pedal is, in fact, a potentiometer and a strip of metal with a spring. The master glued a rubber pad to the pedal. The pedal itself was fixed to the frame under the right foot.
Step six: installing the engine
Next, install the engine and put on the chain.
Step Seven: Control Unit
The master printed the front panel of the control unit on a 3D printer. It includes a display with voltage, current, capacitance and several switches (forward/backward, switch, brakes, light).
Step eight: installation
Connects the engine, battery, controller.
Installs and connects the control unit.
Step nine: LED strip
The rechargeable battery provides 55 volts. To power the LED strip, you need a voltage of 5V. The wizard installs a buck converter into the circuit. The LED strips themselves are fixed on the frame by the card.
Step ten: chain protection
Children will ride on the map and security was an important task. The most dangerous part in the map is the drive (motor shaft, chain, sprockets). In order to close this part, the master made a casing out of tin.

Another important safety element is brakes. The kart already had a regular brake that worked well enough, but the master wanted to be sure that the child who wants to stop can do it 100%. The motor controller has two digital inputs for completely shutting down the motor. He made a special pedal, + brought out the wire and connected a switch on the control panel.
Step twelve: checking
Before testing karting, the master once again checks all units and parts – wheels, tires, brakes, steering.
Everything is ready.
Kart develops a speed of up to 40 km/h. A couple more videos with test drives.
