4 STROKE MOTORIZED BICYCLE 50 MPH

[@07slowbalt]

This is crazy fast on a bicycle. I hit 38 mph peddling down a hill and that was terrifyingly fast on my road bike. Id be afraid with all that vibration your nuts might come out of your shorts and fall into that chain drive!

[@TimpBizkit]

44.5 mph down Aberystwyth mountain road. 42.6 mph down Bathwick hill, though what made that scary was unpredictable drivers more than anything. I did that in the evening when the road was quiet as a truck almost killed me pulling out when I was doing 38 down the hill. On a MTB both times as I hadn't got my road bike yet. I've done 38 fairly uneventfully on an almost flat gradual down with a tail wind and lots of pedaling. It wasn't that scary being a straight main road. I would have been fine going faster but I ran out of leg power and gearing.

[@gamingwithscoob2433]

The max I hit is like 34 down hill on a dirt patch it was scary too

[@TheDustyShredder]

Actually, the suspension will provide better traction, more comfort, and a MORE predictable ride. With that added shock absorption, your bike can actually eat up more of the bumps on the road, leading to less time the wheels are in the air. Please, learn your bike stuff before you comment on bike stuff.

[@charliepatterson9321]

I've been riding all kinds of bicycles since 1969 and have delved into the motorized world over the last year and a half ( my single speed 2 stroke only does 40 mph ) .

[@RemyRAD]

I know this is about three years late but I really enjoyed your ride. 40 mph on a bicycle just about takes your breath away. Especially when you can do that on a straightaway, by only leg power. No external motor. No gas, no electric. Just good old leg power. Multiple 100+ mile marathons. Gives ya, some leg muscles. But that was nearly 50 years ago. But it is that thrilling to go that fast, not on a motorcycle. I love those just as much and have been writing those just as long. But a nice little motor on a bicycle. Down here in central Texas at 60+ years of age. I'm kind of late getting to my second childhood. Oh and it looks like it's almost time to retire. Time to buy an engine for my mountain bike. Since I haven't been writing on any mountains for some years now. I wonder how that would be with my original Gary Fisher? I might also want to look into the other drive mechanism. That allows the use of your rear derailer gears. What's that thing called a, Shaq Jack, Jack Shaq, Jack strap? I mean an old, 10-21 speed cyclist and motorcyclist. Needs more than, an automatic transmission. Well that's it! I've got to get to this before springtime. That'll keep my blood pumping.

[@homerelesperance2857]

Awesome build and video. I had a brand new 2 stroke engine and brand new bicycle build and its top speed was around 38 mph (Using a 32 or 36 teeth sprocket). After reaching over 1100 mileage, according to my speedometer \ odometer, the rear wheel gave out (The side cap on the rear hub where the ball bearings is pressing against it just torn the side cap out (due to metal fatigue, I assume) and out flew out some of the ball bearings). Luckily for me I was able to manage to control my motorized bike and slowly stop my motorize bike without losing control because I was going under 25 mph at that time. What some people may not be aware of is that all bicycle wheels or the hub get worn out from all that mileage it accumulate throughout time, the hub take a toll and when it does, a piece of metal (ball bearing cage or whatever) inside the hub breaks loose, it locks up the ball bearings in the hub of the wheel (I believe that's how it was engineered for), preventing the wheel from moving, that has happen to me before on two different occasion, peddling. Now when you add a motorize gas engine (Which bicycle aren't never meant for a gas powered engine to be placed on and used for) the torque of the engine is strong enough to tear a metal piece that supposedly lock the hub or jam the ball bearings from spinning when it exceed its life expectancy or mileages sort to speak. This is why I always used a speedometer \ odometer to let me know when to change wheels and put brand new ones. When I watch videos of people exceeding more than 25 mph on their motorized bicycle, I sometime cringe 😬😖😓😰 thinking that those wheel or hub will fail someday, they will end up losing control, getting to an accident and \ or injured 🤕. I hope people reading this can learn and take the necessary steps to prevent an accident or injury from happening.

[@zackbfortiscuejr9849]

That's a pretty good setup👍 but those bike rims aren't very reliable at 50MPH😵!!!

[@djasewhole7734]

Bob Most bike rims are typically weak as they weren’t designed for high speeds. The spokes can easily break when under decent pressure, this happens a lot on motorized bikes.

[@youngchild9294]

@@djasewhole7734 really depends on what bike. i mean a DH bike's wheels are pretty tough, some of the high end DH bikes have rims designed after dirt bikes. unless you were thinking of road bikes or cheap bikes.

[@dmoore0079]

It depends on a few variables - what the rim is made of, how it's constructed, etc. Aluminum alloy double or triple wall rims would be more than up to the task. Old school steel rims with at least 12 gauge spokes would be fine too. Tires on the other hand might be the weaker link than the rims.

Properly adjusted rim brakes are WAY stronger than people believe, In dry situations they can even match disc brakes, Issue is in motorized bikes they gotta get replaced every 2 months or so, But as long as they're well adjusted they should be fine.

[@dmoore0079]

@@Jenoxen Rim brakes work very well as long as they're used with allow rims with a good machined edge (they're about useless on steel wheels). Overall though, i like disc brakes using 203mm rotors front and rear. They're unaffected by rain, mud, dirt, etc and provide stopping power that rivals some of the best rim brakes.

No. Those cantilever brakes will never match disc brake performance in any conditions.

A four stroke will also be cheaper in the long run because they are more reliable, are more efficient, and they dont break down on you quite as often.

[@jorelldye4346]

Cheapest entry into decent power is the YD100 2 stroke kit on Amazon for $200. Zeda Firestorm YD100. These bigger harbor freight engine kits are expensive and can be hard to get by the cops because of their size.

[@brianmccann666]

2-stroke... Carry oil with you to refuel with at the gas station. 2 strokes are faster. Easy to install. 4-stroke... Easier to refuel. Try not to use ethanol gas. More torque. Climbs hills better. Slower. Quieter though.

[@jaayse]

@@brianmccann666 2 strokes aren't slower necessarily it all depends on the fuel mixture and sprocket size, as far as the easier modifications go.. The only thing you have to worry about when installing 4strokes is completely overhauling your pedal drivetrain to let your motor have the clearance it needs. 2strokes are easier to fix and have less of a learning curve. If you're going to go with 2 strokes here is an easy way to know how much oil to put in your tank: Say gas is 2.65 for 93 grade and I'm at the gas station. After break-in, which I use 8oz oil for first tank, 6 for the next then 4.5oz for the next tank (not gallon), my bike likes a good 3.5oz oil per gallon. My tank holds about .45 gallons. So if I'm gonna put in 50 cent, which is half a tank for my 2 liter gas tank, I divide 2.65 by 5.3, that gives me .5, or 50 cent.. Now I divide 3.5 by the same amount, 5.3, which gives me roughly .7 oz oil. I first shut off the petcock valve, then I just pour the of the oil in, fill up half the gas I'm putting in there, then pour the rest of the oil in and pump the rest of the gas. After that, I close the tank and lift my bike and shake it all about front and back side to side for 10 seconds and open the petcock and prime the carb. Hope this helps

Mario Salinas That depends if it’s either classified as a moped or a motorcycle. Any 2 wheeled vehicle with a large enough engine that has more than 6HP (more or less that, I’m not sure) can drive on a highway so long as you have a motorcycle license and put all the safety features that motorbikes would typically have. If you’re less than that then you can’t because it would be classified as a scooter.

The motor has a 12t centr. clutch that drives a 30t sprocket on a jackshaft mounted with pillar blocks/pillow bushings. On the other side of the jackshaft is a sprocket with an unspecified number of teeth that drives a 38t sprocket on a freewheel with a 22t sprocket as his final drive gear for the 7 speed cassette/freewheel. Other parts included: aftermarket freewheel for the pedal side, aftermarket intake manifold and carburetor, aftermarket exhaust, and higher grade fuel line.

Use a brake lever or simular application so much easer to use then twist grip junk and breaks less often because not made of plastic ..And the motor bikes i use I rip that twist grip sht off ...

Holy crap a 79cc with a shifter kit. I hope your dad is smiling down on you and not rolling in his grave. But even if he is just know that every motorcycle that breaths air has a lil F you dad written into its DNA. Just ask any 16 year old kid that has pushed his bike down the street so he wouldn't wake up his dad at 3am or Paul Teutul Jr.!
