Introduction: Mini Motorbike From Kid Bike With 80cc Bicycle Engine Kit
In this instructable I show you how I made a small motorbike using an old kid bike together with the available 80cc Bicycle engine kit.
Most people use this to power their regular bikes, but I used it to make a little moped/motorbike.
The total costs of my build are below 120 usd.
5 for the bike
100 for the kit
15 for small materials
The bike kit is available here:
- Old Kid Bike, make sure it's a strong one (no plastic)
- 80cc bicycle kit
- Some metal pipes to make the frame/mountings

Step 1: Check Out My Video!
I hope this video will help you create a motorized bike, or at least give you some inspiration for your own project. Along with the video you can follow the steps below :-)
Step 2: Bike
Start with getting a strong metal bike.
I found one second hand.
Try to picture if there is enough space for an engine or if you are able to create space.
Step 3: The Frame
Remove the old bike parts like paddles and so.
Then we can fit the 80cc engine kit.
In my case I needed some frame customization.
The good thing tough with this engine is that you can just bold it on.
So when I had it mounted the right way I welded back the frame tubes.
Make sure you frame stays straight and strong.
Step 4: Add the Other Parts
Add all the parts to make the engine work.
- Electrical components
- throttle handle and cable
- gas tank
- clutch handle and cable
Step 5: Add the Sprocket and Chain
One of the last steps was to add the sprocket and chain
Step 6: Custom Exhaust
The kit comes with an exhaust, but the position looks weird.
I did some customization to let it look like a proper moped exhaust.
Step 7: Ready
The bike is now ready to go for a test ride.
Later I will add some brakes, but for now I just use the soles of my shoes haha.
Step 8: Enjoy
Make sure to make a 2 stroke oil/petrolmix and enjoy the ride.
