Phantom 85 Motorized Bike - Hits [52MPH +] & Could've Gone Much Faster! 

This is how motorcycles started a hundred and fifteen years ago and there still fun as hell

Big respect man! Takes big balls to ride that thing that fast

Thanks for the ride. Can hear the power band double echo when you got started.Godspeed ⚙️🚲⚙️

Just ordered one all fixed ported and balanced by Don Butler. Can't wait to test it out.

Sounds beautiful.

Yes man nice video nice speed man Wicked🚴💨💨💨💨 as you were

Nice work MJ

Thats really fast for a motorized bike!

Bike sounds good great video make video going 60mph. Bike life enjoy the ride

She was eatin, deff had a lil more, but time to suit up going that fast, ggz 👽

it sounds awesome 35+mph!!

Sounds nice bro good vid

nice . sounded like it was pretty happy between 35 and 40 . thats still crazy fast on a bike . not a big fan of the phantom with all its problems . but i feel once they get it dialed in it will be a good engine . that leak if it dint crack at the wields it was more then likely coming from the gas cap . them cheap tanks suck . the caps can be fixed with a inner tube . just cut out a new rubber seal or use cork gasket maker . they dont fit tight enough . take care . ride safe .

Next video, yes do more tests! Take it all the way past 60mph wide open.

Ripping 🔥🔥🔥

Dopeeee 🔥

Wow amazing vehicle

I hear the rod pin bushing is weak with this motor and Phantom or whatever the company is, is offering a free upgraded replacement. Just a head's up for those who are thinking about buying this motor.

That bike will fly in it even looked like you were a little bit rich on the mix

That's awesome. Glad to see some safety gear bud.

my tank had the same problem, you can wrap the bikes pipe with a rubber strap and then put the tank over the rubber, worked fine for me

I'm goin try to build one of these for myself

She go!

Thanks for the ride.

Careful with fuel leaking from gas cap. End of one of the test videos i saw ark from the plug wire from CDI against frame

Nice work! you got it sounding and running clean :) If you take any long trips with that motor let us know how it does on gas.

Very cool…. What app are you using on your phone? Also, what mount are you using for your phone? Thanks for the video

that fast man

Nice ride and presentation.

I will be so happy if you teach me the process involved in creating this

very impressive!! like the auto start. this is a 2 stroke motor what was top rpm's. was this put together from a kit or do you buke the bike as is? how much invested?. thanks

nice :)

Not bad :)

Use inner tube pieces and ultra copper high temp gasket maker under the rubber seal two should be enough clean well and hold together w the gasket maker Wich is fuel proof will seal well

Sounds like the pipe is starting to come into resonance at around 46, was a bit rich leading up to that. You might try making a header spacer that is gasket matched and spacing the pipe out about an inch to lengthen it about. It will come into resonance sooner. and Yes, it did sound like it would go lots faster.

Kid..... you got long way to go. .

I been dealing with failure as soon as I started messing with these phantom engines on all three version

So cool, i want to put a thumb throttle on my bike. I see the link you put, was it easy to install. Did the throttle cable work? Any tips help thank you

That's a really nice bike can I please ask what kind of carbrater you are using on it I like it

What type of bicycle you you recommend for this? Are the bolts long enough to connect to any bicycle?

Love it! I'm sure your ask all the time what GPS app you use?

Wow that screaming on a bike!

These gas tanks all have a flaw with the gas tank cap and it's really a design to allow air to come into the gas tank so your fuel can gravity feed down to the carburetor to solve this issue is you simply get another gas cap that has an actual gasket but on the center of the gas cap it has an air inlet valve that's about a half an inch above it a little stem if you will this prevents the gas from splashing out but the gas cap itself will have a gasket sealing the cap like a real gas cap and you're welcome

Nice working bike!! 👍👍😁 On a side note, the adrenaline kicks in at 50mph? I'll bet the pavement would kick in really good too, especially on those bare arms/legs. 😮🤪

What oil do you use for this engine? I can’t seem to find what’s mentioned in the instructions as “Valvoline Two Stroke Racing Oil,” is this the same as Valvoline multi purpose oil for two stroke engines? I also already have Lucus’s semi-synthetic 2-Cycle oil, is it safe to use?

yo man, i switched my tank to the supposedly 1 gal tank. worth it for daily rides but I'm sure you'll need one as well. note though that I'm looking for replacement petcocks for the stock one seems to me be weaker than a motorcycle one

I hate 2 strokes, had the worst experiences. Made my bike fall apart, 10 gas tanks in 2 months, went through a few engines, one was a generic cheap Chinese engine, went through a stage 1 engine from bikeberry, completely damaged the engine, bought the stage 2 engine kit, everything worked fine until i tried putting that upgraded compression head on, would not work no matter what i did, like it was obnoxiously annoying, i gave up, but bikeberry’s customer support was absolute top notch, like its something you can really appreciate. Ended up getting a cool muffler, didnt work with the bike i had because the mounts on the engine were at a weird angle which wouldn’t work, they gave me store credit, had got a speedometer they had, better grips and throttle, they were always there, i may check them out later to see if they got anything new, since its been a few years. I on the other hand just got a phatmoto 2022 fat tire, absolutely fun to ride, i was iffy on the speed, but its to be realized that speed isnt always everything you need. I do plan on modifying the governor to get a little more out of it without losing torque from a smaller sprocket. Where I’m at, i cant really avoid the hills so the torque is good to have, got this one hill that has this weird double incline, it’s difficult to drive up with a car in the winter, everybody usually avoids it and take the less not so double inclined hills. All in all, as expensive as the phatmoto is, to me its 100% worth the 1300$. Ive heard the clutch is bad, but i havent had any problems with it.

How many miles you get out of that tank? Your builds are awesome btw!! 😄

How is it so loud with the silencer on it I have the same silencer on my motorized bicycle and it's real quiet did you take something out of yours to make it loud and how is the back pressure well that's probably not the question because in the video I can see it rash real good

Did you change the catb jet? Sound like she's running rich four stroking on low end and not clearing until mind throttle, even though she was pinned most of the time

I wish these were legal it beats battery power I mean you said keep at 42mph you can't do that with battery ita pity there should be a good silencer on exhaust pity about the tank if I was younger I would get one even if the law is to register its worth it no worries of loose power not like battery good video

saludos .loco de ver ese video . no es facil lo de el gps recuerda grabarlo con el screen record de el telefono .porque elgps sale pero cuando lo pones en el edition gopro no lo pone ,recuerda grabarlo con el tel ,muchas felicidades en la 63mph yeeeeeeeeeeeeee

Is that a MZ65 clone and Great 🤘 sounds powerful

Okay I'm going to give a comment a lot of people are saying out there that the yd 100 don't hold a candle to the phantom 85 but the yd 100 don't come with a read valve don't come with other stuff that the phantom 85 comes with so at all fairness. I bought a why do you 100 put that motor on a hyper bike it did 55 mph and I did not have a big pipe on it I used a knockoff mz65 pipe did mild porting to it ran a 32 sprocket on it all I did was clean the ports up on it that's it and the bike would do 45 mph. With no problem so then I pulled it apart out of all fairness because the yd 100 don't come like the phantom 80 kit with the big pipe the Reed valve all that I didn't even break the b**** in I ran it at 40 to 1 right out of the gate stock carburetor stock everything all I did was cleaned it up that's it then what I did was gave it a little bit more work and the funny thing was I didn't even put a re valve nothing on it I ran the stock carburetor then the bike hit 47.49 mph I learned my mistakes on the yd100 so now I got a new one. The fastest speed I hit on my yd 100 was 55 mph but I learned from a mistakes what I notice about the phantom got a lot of low-end power probably mid-range power I'm going to have to get one of those and then we'll see personally in my opinion I've seen guys run 70 plus miles per hour on bikes using s*** carburetors tiny carburetors not big ones it's really not that necessary when I built my first why do you want 100 I went way too big on the ports didn't change the pipe made mistakes we live and we learn it's velocity that's what you want when you're porting staff it's not always let's gouge it out make it huge I found out on these two strokes that is not the answer I've seen guys with stock carburetors f*** somebody up that had a carburetor three times in size tiny little carburetor tore their ass up in the top end it's the velocity it's the flow that's just my opinion

Bro where did u get the phantom from I keep getting them from this one company and they keep blowing up after a few miles just got the"new" one again and had plug out walked it to door and ring snagged on port and broke .I'm trying to find out if the ones off Amazon are breaking like these ones

Is that the stock engine only without any modifications added?

Runs great! Hot Exhaust by your calf isnt ideal lol

Awesome video. Go for the Gusto! You got 57-60 easily 👑

Бро,это круто.

what upgrades do you hjave on it cause im new to motorised bicycles i wanna buy one since they are so fun but i want a fast one like this how much does everything cost? and do u have links

I wish there was a way to just buy that exhaust pre modded to work on the phantom 85.

Hey I know this is one of your older videos but im always looking for a good speedo/gps App and your looks sick... What's the name of your Speedo App if you don't mind ??? OR does anyone else have one similar to his ??? Thanks in advance !!!!!

I want to put a second pasenger on the motorized bike is the phantom 85 good for that or should i buy something else

Is that a stock setup and what size sprocket are you running?

I have a friend that has a Yamaha mate v50 that can reach 120 with just 15 tk carburetor,boost electricity(you know wht i mean), boost exhaust and a 46.5 mm kit ......what type engine is that???

That's awesome how did you get it to go 52 mph and where do you order a phantom 85

Where did you purchase the expansion pipe and the muffler?

How many miles can this engine go??

nice video this engine have more to go . 60mph mmm the bicycle handle that you have good tires and rims red locktite all the bolt torque all the bolts you sure be good . you have a nice set up . ? you change tyhe cluch pads . cant wait to see that 52 on mph on a gopro you have video / what i do i save the video on the gopro app then on the seting you can see on the screen on the same video ones you have that you can record that on the cellphone screenrecord and you can post thst on here . nice 52 mph sorry for my missspeling we be back

I have a 100cc motorized bike kit and it barely reaches 35mph when I try tuning the carb it doesn’t change a thing any Solutions

What app are you using on your phone?. Thx

That awsome speed

Hi can i ask what carb you running and what pilot and main # ?

What sz sprocket you using?

Where can you find that type of exhaust you have?

I just got mine but haven't installed it yet cause it's still too cold out. What oil do you use for break in. The paperwork said 20 to 1 but did you use any certain brand of two stroke oil?

I'm gonna bet once you crack the jug you will find a piece of piston broken off under the wrist pin, for some reason the pistons are cracking around the skirt. I suspect bad casting methods

i notice you still have the stock spark head on it still add a high proformance head on it and you could probaly go alot faster

Sounds like a Yamaha 2-stroke. Love the pipe! what size rear sprocket you have on there?

What size cog do you have on the back

Do more teeth on the sprocket mean faster speed or just faster acceleration?

Hi mj what kind of frame is this thank

Why did you put everything except the sprocket size in the description? That's an important detail.

I didn't clean up till after 40 mph. It definitely likes high RPM.

I really like this engine too and it makes me sick that they are having so many issues with it..I spent 300 on it so I didn't have to make my own ish work and yet I'm still same spot with these engine's 😑I keep getting fools telling me to just do upgrades to it but ish like I said I paid for something I expect to work they way it's intended to.i should have to drop 40 more on it to do what' it's supposed to do.ifvthat was the case I would have just bought the yd 100 and it it my self.that like going to a truck dealers place and buying a new truck with no miles on it and having to take it home and put better rinds on the Pistons lol naw man .I ain't do ish to it so they can say cuz my upgrade is why it broke.the company I been dealing with has definitely kept their ends up with any issues I been having so good looks to them but yea man if it would last it's 6 months warranty I will do upgrades but till then naw I want what I paid for to work

what app is that cause im trying to test mine too

Where do you get that exhaust?

You are CRAZY!!!!!! #1- speed limit on motorized bike is 30 mph or less. Lucky, no cops around, speed checking. #2 - you are in T-shirt and short, at 40-50 mph if you fall or crash, you can say good by to your skin at best, but you can break your neck too. I knew a guy, he was going to the beach on his motorcycle, dressed to the beach, in shirt and short. At one intersection, he had a green light, but a car pulled in front him, so he laid his bike down to slide to stop. He survived, but on one side of his body, he lost his skin and broke an arm and collar bone, some ribs too. He was in the hospital almost a year, laying on his stomach, many surgeries, skin had to be removed from his ass and leg to patch his upper body. Have you noticed, motorcycle riders wear protection, like helmet, gloves, leather dress, rider's boots. Not by accident!

Is that pwk carb I have a 28mm with the Dio set up but it revs up I went threw check all vac leaks what size jets you using if you don't me asking ?

What part of Florida are you in?

Hi rev

50 miles an hour on a bicycle that's a bit fast for me however that is a very nice motorized bike good job

Im buying a Phantom 85. Its asking me to pick a sprocket thooth size, options are 36tooth, 44tooth, 48thooth. Does it matter which one I pick?

Can you send the recipe for it. And how can we limit speed

Did you buy the 36t

What size sprocket

Rid you add anything to it?

Am I can do 110 with a jackshaft kit

What about when hitting pot holes with those tires, and no forks/ suspension???

Get a wheel adapter to mount the cog. That takes alot of the vibration away. Even a few mm out on the back cog makes it a lot more unstable.
