Nice video, brother! Thanks!
For anyone unsure, most Bike Berry bikes come with a 44 tooth sprocket.
Awesome really like this video. Can you do a 4 stroke motor build?
Going back to 36 from 44 T - Great Video 📹!!!!
i used to live in Illinois
Now, do the same tests with the 49cc 4 stroke…..
I've been waiting on this video I get to see them all in action which one I'm going to choose this week after watching this video I currently have a 38 tooth sprocket I had the original 44 tooth that came with the kit after installing the new one I've been able to get around my time more than 35 mph doordashing and Uber eats I'm definitely trying to do a minimum 45 mph and a maximum 50 mph when need it
What kind of frame and Wheels do you use? I need a get a sturdy setup done that could handle those conditions
Do you have a video of a solid intertub on you bikes and what do you think
Your motor has a very severe air leak. Every time you pull in the clutch I can hear the motor rev up. It could as simple as a o ring in the carb or a left side crank seal those are known to pop out very easy.
Yup, it’s the offset intake. Which worked to my advantage on this project. I also ramped up the idle so the motor would rev. I’ve since switched it back to the cnc intake to tame it down.
@@tonytaylor5087 get a longer intake widen the ports 1-3mm no more than 68% bore width or for racing 70%. Raise exhaust about 1-2mm ya can go as high as 4mm no more but on the degree wheel go to 160/165. For exhaust 115-130 transfer 120 good # 125 for 165/170 is ok or 160/110 ex/trans for torque 160/120 for a little both worlds but 180 is as high as y need to go on exhaust 130 on transfers intake well all the way is fine w reeds
Of course it has an air leak it's made out of chineseium these things are garbage but that's kind of what makes them fun
I have a 66/80cc BBR racing engine with high performance head and exhaust with a 32 tooth sprocket and it does great. There's only a few big hills where I'm at but it climbs right up
How fast does it go
@@ezrabroomer565 I've hit 42mph but the rpms were only at 6K but I know it doesn't sound like much but on a bicycle you're flying lol and you gotta remember a car can stop on a dime at that speed but a bike can't. Honestly I'm going to put my 36 tooth back on. It should take my top speed down about 5-7 mph because for one I don't wear any safety shit and I'm a gear head so I'll always go as fast as it will go and I even wrecked once going about 5 mph and I actually got banged up pretty good
I can manage 40mph with a 44 tooth sprocket not a stock motor but still
@@you_dont_know_me6583 that was about a year ago and I've upgraded since then. My main bike has the phantom 85 V3 and my spare has the yd100
I've got a phat moto 80cc 4 stroke bicycle with a stock 50 tooth rear gear. Can't wait to try my new 65 tooth rear gear installed. Should come out of hole faster with 65 tooth gear and climb any hill with barely pedaling. I don't care about top speed. I only go a max speed of 11 mph miles per hour. I have a street/strip car to go fast and race with protection. I bought my rear gear at Sprocket Specialties they can make a gear if they don't have one and pretty fast turn around time.
I have your 48cc BBR tuning. Still breaking in. 44 tooth on. 56 tooth on hand. 18 tooth on pedal side. Would prefer lower resistance to pedal.
?? How about a video on sprockets for the manual side of the bike??
For climbing with these little engines rear gears are everything!!!
Wait what your in arm pit too ? 😳 awesome 👌 but your roads are smooth lucky you ours are potholes landmines & car eaters.
what is break in period and howdo youn known you have passed it? Does the bike make a different sound or noise or something?
I heard that 36t shout out!!! 🤪
I got a 140cc with a 17t front sprocket what size is compatible for the rear sprocket ?
Small world I've been to Kickapoo several times just live about a hour away
I have 36t and works great especially when you peddle to get going
What size tire
I have a 49cc 4 stroke the clutch burns up quick could I switch the clutch to a belt feed one just a question
Can you redo all this with a rear disk brake?
whats top speed 44t vs 40t? can one still get to 31mph in 1 mile with 36t?
I have a stock pexmor 80 cc with 44 tooth sprocket I have no problem getting up some pretty steep hills in Maryland like two to three times deeper than that video
Would've been more interesting seeing the speedometer reading. Overall good video though. Thank you 🍻
meanwhile there's me with a 32 tooth on a 50cc 4 stroke- it's very good for 15 minute+ rides, 30mph on level ground and 40 downhill quite easily! Your 56 tooth really should have less of an issue on hills, I don't see why it was so slow? my 32 does fine on all reasonable hills.
Front sprocket?
@@chickenlittle5916 20 tooth>100 tooth, 10 tooth>32 tooth is my total reduction. 26 inch wheel. My engine is the 142F topping out at 8500 rpm.
Air leak in motor, and the carb tuning looks like crap. Engine sounds all sorts of wrong.
i think my personal longest trip on a 2 cycle system was about 150 miles in a day. 3,500 ish miles later and she still mostly purrs
What kind of handle bars are on that bike
what cc motor is the bike in the video i have a 100cc I built on my bike myself through watching UA-cam vids it came with direction but it might of been Egyptian hIlaglyphics for all the help that was. Because ccs would matter in this situation
From my experiences it takes over 500 miles to break in correctly compare to the manual 310 miles. I try running 20:1 with super synthetic oil it runs poorly. It does like 16:1 it run great and more power. With Z8C plugs runs cooler at about 275F but it take 5-10 minutes to warmer up.
hmm in my experience these oil ratios bog down my motor (*and fowls the plug with oil sputtering out the exhaust), and so I run at 32:1 with no engine problems after 3,500 miles
Is going up a hill the same as carrying cargo in relationship to these numbers? In other words a 56T sproket is going to give you better torque to carry a heavier load? Like groceries or me getting fat?
Correct . However motor compression makes a difference.
I'm currently replacing a 2stroke engine with a 4 stroke engine is the sprocket the same in both kits?
should be.
The best sprocket for me is 40 tooth.
I bet that’s perfect 👌
29.. in Florida
The motor shouldn’t die out like that going uphill on a 36t sprocket sounds like your lacking power and you have a air leak as it revs up when you have your clutch in I would port your cylinder cut the exhaust pot 36-38mm wide 1mm on the roof intake not as wide and 1-1.5mm down you will have more rpm less torque but torque isn’t that important I don’t run reed valves I say you can get better performance out of a piston port with a ph21 carb and there a lot easier to tune I’m running a 32t on a 66cc get 52mph top speed uphill does 20mph but there are some drawbacks to piston port although very informative video good job 👍
Can you help me me out with some information if you could please! I just built a really kickass motorized bike,it’s almost complete! Is it a bad idea to go with a 14 tooth sprocket in the rear! Instead of having the 46t installed, my pure cycle bike came with a 14t already installed on the left side rear and it fit and lined up! Is it wise or idiotic to do! It’s my first build and would appreciate any input! Good or bad! Thank you guys!👊🤘
It won't have much low end performance but will have good top end the stock 44t you can get to 32 to 34 mph and every tooth less is roughly 1 mph faster but it may take a long distance to get to top end with a 14t it may help to have higher compression and a turned exhaust to have pull or acceleration.. me I like the 40 or 44t sprocket to get to cruising speed fast say 28 30 mph because of stop and go for city travel with a 14t by the time you get up to speed you'll have to stop and start the long process all over again unless you're on country back roads
Higher the compression more low end torque I have mine at 165 psi some of the stock engines may have up to 120psi but most are around 90 psi or just in-between
I'm in Costa Rica. Many hills here 20 to 30% grade one even 41%. My driveway is 22%
But a problem. Both the clutch and front hydraulic disc brake are left hand. I have a clutch of surgical hardware in my left arm. So looking for a way to set up a left hand clutch. My engine a Chinese 100 cc 2 stroke without markings or manufacture, mounted on a Gary Fisher 18 speed 29 inch mountain bike with 29 inch wheels and 56 tooth sprocket. And I am 76 years old 5ft 10 and a half, 178 pounds. Until 4 years ago could handle hills on non motorized mountain bikes even in the Andes at altitudes in excess of 16,000 feet.
What's your maximum speed on a 56 rocket
Haven’t done a maximum speed test yet. Once the engine is dialed in more I’ll do it.
i ride the huffy-davidson chopped
hi Tony I noticed last night I have a flat tire on the back also hahaha
Had a blowout on a ride just a few nights ago…. Sucked
For torque 56, for speed 32 or 36
Absolutely!
I am living in area with 12 degree hills. Also i have only 1kW 50cc 2t motor. ( More is forbiden thanks to evil EU)
I just ordered 56 tooth sprocket. At the moment i have 44t stock sprocket and i was only able to REACH first third of the hill.
12 degrees is almost twice what I experienced here!
Můžeš si koupit větší motor. Nikdo tě osočovat nebude. Lidi z mého okoli mají 78 5 ccm a policii je to jedno
@@tonytaylor5087 update:
I got 58 tooth instead of 56, it was out of stock. So i am able to ride those hill with little help of myself, just little pedaling. Also i have looked at map and ita actually 10 degree not 12.
What motor are you using? Mine is 50cc sunway 2 stroke 1kW. its also new motor, 16:1 gas oil ratio
@@Matthew-wj8cm máš pravdu že je to policii jedno, dokonce jsem jednou zastavil a ptal se jich a oni mi řekli, že ani nevědí, že něco takového existuje.
Spíš se bojím pojišťovny, kdyby něco...
@@nasledovniknikolytesly4351 chápu. No vtipné že jsme se setkali na BikeBerry videu. Tihle týpci mají hodně hejtu mezi lidma co těmhle motorům rozumí a zákaznický servis taky nic moc. Takovej F-Zero rám bych chtěl ale dostat to do našich končin? Ten F-ZERO od Minibike-Shop mám doma ale není to ten pravej.
5:23 pittburg area, has way Steeper Hill in parts .. but its Still fun for bikes, i run a 42 .. but i like to putt around ,, and wish you should Show Rpms, at SPeed .. and you didn't , maybe be Video 2 , and 3 , one for hills one For flats,, please buy a 10$ .. Cord that GOes around the Sparkplug wire, and Let us know the rpms , and the Speed your Going with the Gps , or onboard Computer Mph ... i cant Afftord to Buy all these SProkets , and this is something I'm Shocked you didn't do . ( i even Posted this in you questions on What we wanted to see .. and i gues you didtn take anyone ideas ..
So many questions.
I swapped out the stock 44 tooth sprocket for a power 48 sprocket. Only now the chain just fits perfectly and no tensioner is needed. Should I leave it off? I have a spring tensioner but it seems like its just going to add extra drag
Tensioners are often more of s hindrance than anything else. Even with the original sprocket its better to just shorten the chain than to add a tensioner.
I run an 8 tooth for my daily highway commuter.😎
8 tooth?! Please explain 😃
Those aluminum sprockets wear quick!
Only if your chain is wore out
@@zimmhollowfarm8414 should you oil the chain?
-( ."?... Hey Tony why is it if
,.//I ) you had on the 56-T
( x))I\ Sprocket on the
wheel last the bike wheel tier
is flat with a different sprocket,
the sprocket has the disc brake
rotor mounted, we like to see
how you got the 56-T sprocket
and disc brake rotor setup Tony.
I feel like everyone is forgeting the diffrence in tires makes a gearing change i use 20in tires and a 36 sprocket on a yd 100 bmx bike it was tight but i made it fit i hit 25 but im on break in
Btw it goes up hills no problem
It is geared pretty low but I wanna be able to go up hills so that's y
What is the biggest sprocket you can have on the back until it interferes with the disc brake caliper?
The 44 tooth is where brake modification begins. I just took it off for the test but if I was going to stick with a bigger sprocket then I’d enlarge the brake disc and extend the caliper.
Thanks that really helped out. To modify the disc brake for a 56 tooth sprocket , would you buy a bigger size rotor (what size) or would you modify the existing one? Also for the caliper mount, how would you make that bigger? I’m trying to figure it out because I want to get a sprocket as big as I can with a disc brake still working as the brake system
You can't get anything bigger than a 36 tooth sprocket with a 203mm rotor.
Hello sir My name is Melvin I got a question maybe you can help me I got a sprocket in back but I got a better one a lot better team with the kid I bought an updated better one it's a 44 or 43 but I got a I forget that chain but it's a change I think it's four or 15 or something like that and I ain't got a chainer on it yet but I just trying to spin it and the top yeah I've seen the top in with your hand it don't just drop in then you start turning the back tire and once it jump not seat right with the chain in the gear but I knew the gear sprocket is made for that because that's what the lady told me but what do you think or do you have a video on that can you send me a video if you have one or can you make one send it to me I'm very appreciated because I'm going to headache trying to work on it and I know about changing stuff because of the ground go karts all that and motorcycles but that's the first time I see where it don't seat right and you can spend it and then you try to pop off from the top please let me know cuz I ain't got this rocket type down nothing like that yet because I was trying to line it up and when it jumps like that I can't you know tell okay I appreciate it sir have a good day sir
Hey Melvin, no offense intended here but please use some punctuation. It's difficult to figure out what you are saying without any commas or periods. It all runs together and becomes a chore to decipher. Thanks man, good luck with your ride!
Uh...what?
how is it so powerless, a regular 80cc without the muffler cap would have no trouble getting up that hill
For real, Im able to go up decent size hills at a low speed no problem on mine. Cap removed with a tapered end piece is all I've done.
Top speed would be cool
With changing sprocket and chain each time, had to be time consuming.
It was a ton of work! So many hours in this just to make it reliable and accurate 😃
@@tonytaylor5087 it may have been a lot of work but all your efforts show a far more accurate picture of gearing sprockets correctly. Many will appreciate this descriptive information when choosing sprockets. Much gratitude to you as the hill I have to traverse is an average of 14 degrees and over an eighth of a mile. Hard on brakes goin down. Performance engine heavily ported 21mm carb expansion chamber lightweight aluminum with steel swing arm soft street suspension . Even so the hill is at a barely legal grade limit (one short section exceeds the 17degree limit at the very top making it a challenge with my 42 t. Halfway is as far as I’ve got. I’m thinking about that 58 dollar nitrous kit for this one hill. The rest of my travels are small slopes mostly flat so I don’t wanna go to a lower gearing( larger sprocket) If I could attack the hill at a speed nearing the powerband 6800 rpms attempting to accelerate but nowhere to build up speed over 10mph at bottom. Jack shafts rob power and good ones are heavy. I’m thinking about a two sprocket using a modified upside down front derailleur as my motocross chain tensioner will easily take up the slack but I gotta get up this damn hill at least twice a week. Stranded time an again. Pushing it up or leaving the bike roadside not an option so I just wanna sleep in my own bed as opposed to roadside or waiting on a truck or disassembling my bike into 3 parts to carry in a car. WTF am I gonna do? 50mph now w38t now 42t.
Thanks for the kind words. Sounds like a steep hill you’re dealing with that needs a creative solution. Keep me posted!
@@tonytaylor5087 yeah something tells me helium balloons and rocket power might be a bit too much Wylie Coyote for this county to tolerate. Alternate nitro / alcohol fuel tank ?? Maybe even devising a quick change sprocket . One damn hill is not gonna beat me . Actually it’s a mountain but im gonna chop it down with the edge of my hand🎶
Haha you’re the man!
you should of Done a Gps Tracker,, (or computer speedometer... )
And Put the Rpms THing on the Spark plug Wire ( 10$ on Amanzon )
so you can show us
The rpms , at The Speed...
,, up hill , or Flat .
. ( i think just FLat at rpm , and Speed )
you did even need to hold it Wide open ,... i just Want to know , what the gear Ration is ,, WIth Rpms , at Speed .. but i guess your not a car Engineer on Auto / manual Trans
Dude my 72.6 true cc eagle bbr falcon 911 build with 21pwk would idle up that hill, everyone check out my bmx concept build, it’s about 7hp now
Someone needs to make a manual transmission for this kit
I weigh 155lbs. The 32T does me perfectly fine. I like top end speed. I don’t care about torque I can petal like the bike was meant to do. Once I get the rpm’s going I have more torque than your big dumb 44t-53t sprockets on flat ground gaining speed WAY faster than a 44t.
If your engine isn’t ported or upgraded some you aren’t going to get rpm’s with a 32t.
32 and 36t are the best sprockets for the 2 strokes if you weigh 155lbs and like speed.
The 20 mph test is strange for me because the bigger the sprocket the more power/ acceleration and that was the opposite in your video how does a 36 tooth have more power/ acceleration but doesn't go as far up the the hill
Yet on certain set ups one can create great speeds and not sacrifice in power a whole lot. I'm working on providing Proof of my theory yet it's probably been proven years before me.
Your description is deceptive. 634-588=46 feet rise. The graft angle you show on screen is 25 degrees. ???? Maybe you meant 7 percent grade? I have a few hills like that here. 36T l had to pedal at 1/2 way, 44T l start at 25mph, no pedal, and reach top at 22mph, not bad. That's pulling a WeeHoo single wheel trailer. The 36T was stock, the 44T is BBR Stage 4.
They bought Tony speed tool's??? What's next radar & a ticket ? 🤣🤣🤣 speed demon 😈 🤣🤣🤣💪.
get a 4 stroke and put what ever sproket you like, right ?
M stock yd with 36 me 320 pulls better than most all your sprockets
That silver bike doesn't need chain tensioner, especially on top,why,must vibrate like fk
Real Simple 36 tooth faster 4 stroke , 44 tooth more torque
better yey, 10 speed the motor !!!!
These frame styles look awesome.. But they also look and I've been told they are an ergonomic nightmare.
No way that's a comfortable riding position for more than a few miles.
who CAres how FAst you were going , if we Dont know the Rpm ,, And tire Size of bike ...
we need to know ,, SProket size ( tooth ) ,... Rpm ( you don't need ot hold wide open ) .. and WE need to know The speed you are Going at that Rpm ...
we need to know ,, SProket size ( tooth ) ,... Rpm ( you don't need ot hold wide open ) .. and WE need to know The speed you are Going at that Rpm ...( please Make a 2nd Vidoe ... also , just Use FLat .or just do a 3rd video With all up hill With ..Rpm / mph Speed, and Tire Size/wheel size)
those hills are nothing bring it to sf at 41 degree hills
Is this a 80cc motor? Your bike slow.
I would never buy from BikeBerry
Horrible customer service
Oh I forgot to tell you it's a 70cc motor thank you it's a Chinese motor
Rigged to sell parts!
who cares How fast it Takes you to get to 20 mph , lmao !!!
( sorry that was rude ,,, I like your Channel , i just thought you would of Used at least an Rpm Spark plug wrie cord to see that What RPm , was At at the 20 Mph Speed
Absalout garbage sprockets. Aluminum turns to dust in record time
yo he make motorized bicycle look so slow and lame
a stock 80cc without muffler cap can wheelie from +30mph but his bike cant even climb a hill
Lmao what a crap video. Carb is deff not tuned. Engine is not broken in, guy couldnt even use the clutch. And talked way too much.
Here is the answer to the question everyone wants to know, whats the difference in top speed? Here is the answer, on an average 26" tired bike and a standard kit which is based on a 44 t rear sprocket, for each tooth you go down you increase top end 1mph and the opposite. So if you go 30mph on your bike with a stock 44t rear and switch to a 36t, that is 8 teeth or 8mph, so now you will hit 38mph with a slower takeoff and more pedaling. same way, your 44t will outrun a 36t until it tops out then the 36 will overtake it and go 8mph faster all other things being equal. your welcome!
