Dear Everybody,
Today I would like to introduce How to Build An Awesome Motorbike Using Truck Wheels And Engine With Capacity 150 cc.
I hope you feel interested in my video.
Please like, share and subscribe my channel to see more videos.
Thank you so much!

Personally, I reckon Fawa Bros should be banned, from the internet! Heavens know how many will injure themselves,
emulating their nonsensical "fabrications".
Well, I have seen people built much more dangerous things. It was actually pretty well constructed. I found it interesting that they have so many parts "just laying around" that fit into that build so perfectly!!! HA
Fawa Bros are on my "do not watch" list...Quote:

Pretty much a given the entire build was pre planned most everything on the build was new parts and materials except for the truck tires, even the little engine looked out of place on that rusty old frame it was removed from, just a little dust that blew off way too easily. If the bike was meant to be ridden for more than just the test run in the video it really should have a completed frame instead of just a stub holding the gas tank that tube needs extended to the back of the frame to complete the loop.Quote:

Idea looked entertaining; until comparing tire/ wheel weight & diameter to snack crackers identifying as brake rotors. Then, such a tire section would not be a turning sensation, entering a corner on the corner of a tire.
WTH, isn't a kickstand still needed?
Turns out less appealing than modern 3 wheeled vehicles that look like Batmobiles.
Something that underpowered to weight ratio due to the tire and wheel weight the square shoulders of the tires might just be benefit for slow riding. Obviously too much gyroscopic energy to take corners at very high speed. Simple fix to the tread shoulders would be to shave them down to a radius.Quote:

I once bought a Honda 50. At the time I might have weighed 100 lbs. it would carry me up to about 55 MPH 60 if I had a long enough level road. It had a 40 tooth drive sprocket, I made a 36 tooth still ran 55 but now only in 3rd gear. 4th required a slight downhill or it would lose speed but could get about 70 eventually. so I made a 32 tooth gear could only get about 45 in 3rd, 80 in 4th with a decent long downhill. This caused me to think the opposite direction made a 44 t sprocket now I could get to 60 fairly easy even with a slight up grade, but the engine would wound a lot tighter. I made 1 more sprocket with 60 teeth 30 to 35 was tops and the engine was wound as tight as a banjo string, but the little bike could climb hills with stock bikes having nearly twice the CC's. This was my 13/14 year old self-taught gear ratio learning experience
