Making a Honda GX120cc Motorized Bike

This is part 1 of a 3 part video series on building a Honda GX120cc motorized bike. I wanted to challenge myself to do this build, as I strive for quality in all of my projects, and in doing a lot of research, I found that the Honda GX120 engine was similar to the Preditor 212cc motor, so I knew I could figure out how to make it work. Honda motors aren't made in China, and they are very good quality, so I'm hoping this will be the best motorized bike build out there!
Stay tuned for part 2!!
Parts I used:
Transmission-- amzn.to/3966RiX
Engine-- www.amazon.com/Honda-GX120UT1...
Exhaust Pipe-- amzn.to/3dkxd3Z
Centrifugal Clutch-- amzn.to/3a7mWX9
Parts I used to build the bicycle are in the description of this video: • Building an 80cc/66cc ...

Tip: Get the bicycle called - "The Chief" from company Firmstrong, (comes in one frame size only size- 21.5") the whole engine will fit in the frame including the tank and the stock exhaust.

This is a nice video. We don’t really work on bikes or small motors but this is very informational.

[@st.paulmn9159]

Just make sure your bicycle can handle the power. I’m comfortable with 3-5hp on steel cruisers from the 50s

[@Initial_Gopnik]

I have used old bicycle wheel spokes with great success, they’re usually stainless steel so they don’t rust easily and they are very stiff where they are bent and can be used for odd bends and L shapes to clear different components.

Great video

[@buckboula1304]

Where did you find the transmission plate you put on that motor?

[@ENTHUSIASTICFIFAFAN]

Love the video. This is gonna be my project once i have enough money to buy the engine!!

[@noahhamilton2130]

When is the part 2 I want to see you ride that bike

[@Libertymongoose420]

Obviously you never seen my videos on my previous channel libertymongoose420 I had the clone of this engine a 118 cc lifan 4 HP mounted on a modified friction drive mount I use a centrifugal clutch for the drive its been very reliable for the past 3 years bullet proof engine.Anyways glad to know it will fit in this frame good job

[@crazycarpes]

beautifull engine!

[@paulgibson8846]

What is the length of that engine? I got a post on my Diamond back 26" that OHV gets in the way of success.😢

[@callum8143]

Great vid 👍

[@norcal8718]

Cool video bud. It's good to see the next generation getting into mechanical work and adapting with your own ideas. I want to give you a suggestion if you don't mind, you should probably get rid of that Governor all it does is slow the engine down by keeping it from full throttle. Good luck and be safe 👍🏻

I have a phatmoto with 79cc, i. Thinking of rigging either a 120 or 160, cant decide yet which would be easier/better but was wondering what you think about the 120cc comparred to the torque and power of a 79cc, do you think its a noticable difference? Can maybe climb hills better? Thanks

[@larryshaver3568]

where did you get your engine? i'd like to know Honda makes something smaller too
