Are 2-Stroke Bicycle Engine Kits worth it? Let's find out!

Thanks for making this video man really helped with putting together my motorized bicycle

I'm on my second build now!!

Not really? I've had a 2 stroke engine. That was specifically manufacturer. One of those high speed ones that were very expensive and very efficient it's quality over quantity

And yet 3 days for me. Was all that last because, after 3 days it broke down, didn't even work anymore. I have to take it to a mechanic. And he can't figure out what's wrong with it

And it's costing me over hundreds of dollars to try to fix the other one

I think 4 stroke engines are more worth it than a 2 stroke engine

I've had one for a while and never had 1 issue. Not a single one sure I may have to adjust. The chain and the sprocket, so it wouldn't jump. Or loose

But never had an issue. With The 4 stroke engine unlike a 2 stroke engine

I used one of those engines for a year, and every thread in it stripped out, the first time I retightened them, turning it into scrap. I now have a Predator 212, non hemi engine in my bike, which required a frame stretch to make it fit, which cost me $500.00. After some research, I found the Monster 90 engine, which is a 4 stroke, 78.5cc, that will fit, without frame welding, and with a Comet 20 series CVT, and a Juggernaut clutch from Go Power Sports, you have a bike that performs just like a motorcycle, taking off from a dead stop, in low gear, it's like having a 3 speed transmission, with the cvt, and the GPS clutch works flawlessly, no more peddling to get started, no 2 stroke oil dripping off everything, no mixing gas and oil, just riding, topping off gas at a gas station, doing a half liter oil change, once a year. The Monster 90 engine produces about 3.5 to 4 hp, at 4,000 rpm, and, depending on the rear sprocket teeth, will comfortably reach 60 or 70 kph. This engine is very well made, and will last for years. I made a chain tensioner that attaches to the backing plate of the cvt, and eliminated that dangerous piece of scrap you have there. I also replaced the rubber sandwich sprocket mount, that ends up snapping the spokes on one side of the wheel, after about a year of use, with a 5 spoke mag wheel, with the sprocket bolted on where the brake disc normally goes, and caliper brakes on the rim of the wheel. I have been riding this set-up for 7 years, and it runs as strong today, as the first ride. I installed Honda 10 amp charging coils, and a 3 magnet flywheel, with some machining involved, and I have a Harley, 7" front led headlight, a double jet led taillight, with turn signals, and brake-light switch on the rear brake lever, and a battery that stays charged. If you want a serious bike, this is the answer. PS Don't use that chain tensioner, it's dangerous, for obvious reasons.

I have no practical use for one of these, but they're so cheap and I love working on old bicycles (they're a dime a dozen and there's an infinite variety of projects you can do with them), so I'm probably gonna build one of these someday. I have this crazy idea to build one and then build a makeshift trailer for it and take it out to the lake and go camping. 😎

Dumb question can you still go through all the gears??

How are these things even legal?

fuck e bikes we bring back classics sound and vibration i love it

is a two stroke worth it
that depends who you ask
some would not trade it off if their moms life depended on it
others can't stand to look at them

How's it holding up 4 years later?

For the first run a broken in the engine with AMSOIL SAE30 break in oil. I used a 25:1 oil gas mix. I got the best result besides using regular two stroke oil. After the second tank of gas I want back to 2 cycle oil. Using a 40:1 mix. Or you could used a regular 20w50 high zinc oil 40:1 mix. The problem with two cycle oil is there not enough high pressure and zinc additives inside so a lot of those engine fail prematurely at low hours. So using a 25:1 AMSOIL or which ever brand break in oil 30 weight will coat the bearings and piston stirt with a good layer of zinc to prevent scratches and scuffing during the first 1 to 3 hours of running.

I need some help connecting my kill switch on a Pexmor 100cc kit. The kill switch has a green wire and a black wire with a white line. The engine has a black wire and a red wire. Anyone know which way these wires connect? Thanks

This is the video on Amazon

Your videos make me happy

What's the Km/h mileage on these?

I bought one for 100$ with tax and shipping. You need some mechanical skills but it came out great! It flies!

If we are destroying the planet we better have a fun time

I have a question about 2 stroke Gasoline engine Is it Safe for my 2 stroke engine to use Diesel as a 2 stroke oil

Is there a way to make the 2 stroke engine quieter 😅

Thanks Project Farm 👍

Why would you use an ancient, loud and dirty 2 stroke engine instead of en electric kit?

will it work with rear disc brake?

About 18 years ago I bought a 49cc kit but bought a 41 tooth sprocket instead of the standard 44, put it on a solid steel Malvern star 26in bike with no suspension and it went great, Max about 60kph which was slightly faster than my friends better quality more expensive kit on an alloy bike... the sprocket was a prick to get on but was alot of fun.
Although if the 80cc only does that same speed you won't see me buying one, the stealth bullet 1000w scooter I had was ALOT quicker albeit more dangerous (broke 7 bones in 3 crashes) lol

These things are unconscionably filthy.

Nice. Very informative. I had always wondered about those Chinese versions.

I have an IMAYCC 80cc I ride it a lot broke a few chains but overall it gets me around to run errands

That's awesome. I'm gonna put one on a beach cruiser.

I know it's old but a fun video. The compressed air on the hand grip was worth the price of admission!

In most countries if you would want to drive this outside of your private property, you would need to register it (have fun trying that)

I did one in high school. Had probloms with the chain eigher breaking or falling off the sprocket. I reached like 38 mph once.

More oil more compression more vibration. Or it could use a little tune.

Thanks for the Turkish subtitles

exact same one i just got in 80cc and my cruiser bike tubes were to big for the braces under the engine it ended up flipping sideways and breaking my chain and pulling out the spark plug boot but after getting that all fixed for 30 bucks (bought a chain breaker for 40 bucks but returned it when i was done lol) it now works like a dream so fast to

What's the performance, like speed and power?

Engine on a bike?

Skyhawk is the top of the line for motorized bicycle engines. I had one about 10 years ago in high school. I used cheap components with the expensive engine so I worked on it all the time lol. But I could get that thing up to 50 miles an hour. I miss it. I should build another. Maybe this time with nicer parts.

I've seen these in foreign countries but think e bikes make them obsolete

Yeah I came coming down from tehachapi down Cal City boulevard blew my tire out over the 58 freeway and 14 freeway

Hello, i know this video is 6 years old but ive seen that you still respond to new comments, so i plan on buying 80cc engine for my bike, how fast does it go?
Sorry i havent watched video carefully so i maybe missed something

the bike brakes and the chain gets hard without putting or using the brake, how do you fix it?? Is it possible that the motor is tied or the cloucth is stuck??

Does anybody know what fuel this takes?

But what if you have disc brakes?

Do think this is legal in Iowa (no license)

i bought one, thanks for the tips.

do you need oil changes on these things? for the crank

One I had had two cables to a bigger carby. The single cable carby one is the base model kit.

They are, I've had a couple. One I had up to 40mph.

It looks fun, but in my country if vehicle have internal combustion engine – you need a driver's license(scooter if 50cc and lover, and motorcycle if more than 50cc)
