Hello fans to craft, this time we will consider how do it yourself make a very simple electric bike based on a screwdriver. The drive is carried out to the largest driving sprocket of the bicycle using a separate chain. A visually used engine is similar to. If the battery runs out, you can always reach your destination with the pedals. The drive sprocket on the engine from the rear wheel of the bicycle is ratcheted, so you don’t need to twist the engine when working with your feet.
The author uses two batteries from a screwdriver as a power source. Of course, everything is not assembled reliably, but, nevertheless, homemade has the right to life.
Materials and tools used by the author:
Material List:
- ;
- two batteries from a screwdriver;
- switch from a screwdriver;
- bike (with gears);
- boards;
- a bottle;
- wire;
- screws, screws;
- epoxy glue, cold welding or the like;
- chain;
- an asterisk with a ratchet from a back wheel of the bicycle;
- wires.
Tool List:
- glue gun;
- drill;
- soldering iron;
- a hacksaw;
- scissors.
Homemade manufacturing process:
Step one. Gearbox installation
First you need to disassemble the screwdriver and remove the gearbox from it. We have to install it on the frame of the bicycle. As a basis, we take a piece of the board, to begin with, the author glues the gearbox with a glue gun.
Next, the author wraps the screws in a tree and makes a clamp from copper wire to secure the gearbox. Well, then this whole thing can be covered with cold welding or something else based on epoxy glue.
As for the drive sprocket, the author glued it to the screwdriver's chuck, the installation process is not shown.
We fasten the board with the mounted gearbox to the bicycle frame, using screws for attaching roofing materials. After that, you can already pull the chain.
Step Two Switch Installation
We do not need to install a bicycle switch, here we use the same switch from a screwdriver, which will allow us to smoothly control the speed. Under the switch, the author made a frame of wood, gluing the details with a glue gun. We install this whole thing on a frame using a clamp made of a piece of rubber from a bicycle chamber.
Step Three Battery Installation
The bike will be powered by two batteries for screwdrivers, the author connects them in parallel to increase capacity.Next, you need to make a case for the batteries; its author makes it out of the bottle by cutting a window under the battery. And after that the bottle is mounted on the frame of the bicycle, there is a special holder for it. To make everything look aesthetically pleasing, we paint the bottle, and we securely attach the batteries with electrical tape.
Step Four Final assembly
At the end, you need to connect the switch, we will control it using one of the handbrake handles, connect the cable so that the loop is compressed and pressed on the button. We fasten the motor to the gearbox, not forgetting to lubricate the gears well, also solder the wires.
Everything is ready, connect the terminal to the battery and try to start the engine. Unfortunately, the author did not show us the test of the car, but from the spot the bike twitches quite confidently, the torque should be enough to ride.
I hope you are interested in homemade good luck and creative inspiration, if you decide to repeat it. Do not forget to share with us your ideas and homemade products.
