Motorized Bicycle Must Have Parts! Rear Hub Sprocket Adapter and Chain Tensioner Idler Upgrades.

[@asphaltcowboy7868]

I have been on this kick lately about chain tensioners..and you have it right..this is the way I have mine set up..spring loaded off the clutch cover, (away from rear wheel) plus changing out the plastic guide wheel with a metal sprocket..way to go..great setup and build

Hey man, I used to build these things for sale and I completely agree with you 100%. In addition I also would get completely aluminum throttle with rubber grip since the stock ones have broken for me many times.

[@theatom7264]

Had them break on me to. So for my next build I plan on getting a high quality motorcycle throttle. Would be a huge step up fromt the kit stuff.

spacemonkey yeah jnmotorbikes I believe is the business name sells all aluminum throttles I got on one of my bikes, works amazing and very durable.

[@0Kizzy]

A huge world of difference, takes all the vibration from the assignment an smooths everything out

[@metal-lm6ue]

Hell yeah❤ the only thing different I’ve done in comparison is shorten the chain more you only need an 8th to a quarter inch of slack on either side of chain . Too loose it can bind up on the engine drive sprocket and causes damage to engine case.happened to me several times. After shortening that chain that all went away and even cut the noise more.. adapter sprocket’s are the best and the spring tensioners are the best I’m agreeing with you 100% except for shortening the chain more for added stability

[@anthonyharman7837]

I have just bought one of these engines i have ordered all the up grades as I didn't like the chain tensioner air filter or rear sprocket set up well Done good explanation

[@samurphy]

With those horizontal dropouts, you wouldn't have needed a chain tensioner at all. You could remove the right number of links, and slide the rear wheel back until you get your proper chain tension.

Spring tensioner would be the ideal solution, but I used the stock one. I put a rivet in it to keep it from falling into the spokes. I did the same with the coil and tank to keep them still. Very cheap upgrades!

[@wildbill23c]

I'm still using the original chain tensioner and yes, if you aren't careful that thing can easily slip and lock your rear tire up. One thing I did to prevent it was take an old bike inner tube and cut a couple pieces to wrap around the tube on the bike then installed the tensioner over the inner tube and cranked the bolts down, it hasn't moved at all since doing that. I'm thinking about updating my rear sprocket to the adapter type setup you have, it looks far superior to the rag joint setup. I'm using the rag joint setup right now, but the sprocket & adapter is definitely on my upgrade list. As for the rest of the engine I don't really plan on doing anything else to it for power, it does 30mph on flat ground, that's plenty fast for bicycle tires LOL. BTW, great detailed video and explanations of why these items need to be addressed, the tensioner is a major safety issue, if that thing slips into the spokes of your back wheel, it can throw you off the bike in a heartbeat. I didn't know about gasbike.net until running across your video, I got my kit from Bikeberry, but looks like gasbike.net has far more accessories and options.

[@rimshotrecluse9345]

Careful with gasbike though man. They have HORRIBLE customer service. I don't really deal with em anymore.

[@jumpa01]

I never did self-taught we know more about them than the people who sell them

[@wildbill23c]

Rimshot Recluse They're all chinese engines, none of the places that sell this stuff have any sort of customer service skills :(. I bought an analog speedometer kit it broke after the first ride of less than a mile, was far from impressed, bikeberry wanted me to pay to ship it back to them, I said hell no threw it in the trash and ordered a digital one from ebay which has worked great. Reminds me I need to get more fuel LOL, ran 87 miles on a gallon. Seems to run great other than the couple issues I've had one broken mounting stud, and the speedometer.

[@adamcolbertmusic]

This is at least the third hack I've seen/read about for using old innertube ;) One was to use it between the engine mounts/brackets and the frame to reduce shaking, and the other was to cut circular "grommet" type pieces to seal the [cheapo kit] gas can cap to the can so as to prevent leaks while riding.

[@jets8991]

This comment seems an awful lot like a gasbike.net advertisement

[@4514rooster]

I figured out you can extend your chain tensioner if it’s hitting on something with one of the sprocket plates incase anyone has had that problem.

[@kalleklp7291]

The chain tensioner was my nightmare too..! I saw this piece of shit tilting towards the wheel while I was doing 40 mph. So, I made a similar solution myself. Yours is made out of aluminum mine is stainless steel but only 2 mm thick plate and the arm has a little bend lengthwise in order to be light but incredibly sturdy. I might invest in the sprocket because I haven't the tools to CNC machine it. Happy riding..!

[@austinbennett1463]

I bought my bike already built and ready to go from a guy. I road the bike before I bought it and everything, everything was fine until I got home and tried the bike again. The tensioner that they give in the kit is horrible! I had 4 spokes ripped out of the rim!had to get a whole new wheel, then broke 3 spokes out of that one. You are way better getting a tensioner like that. I will be getting these parts as I get paid. Loving your videos, I am learning a lot, thank you man.

[@ciciw4158]

I have that problem on my bike with the stock chain tensioner

[@Jim-ee6pz]

Always change out the bracket bolts for grade 8 hardware! the stuff that comes with the kits will strip before they can really hold that bracket tight enough not to move. Then, buy the black spring loaded chain tensioner from eBay - Works great and comes from Montana.

[@honorb4glory606]

I have the hub adapter, but I've been putting off the tensioner. I can't believe I never thought about the stock tensioner being pulled into the spokes. As long as it's tight, you're good, but I'd rather eliminate that possibility altogether.

[@0Kizzy]

Very good idea not only eliminates that issue and makes the bike a lot smoother all around

[@dominickdunham648]

Very good idea getting a different tensioner. I have had mine rip several spokes out but I can't afford to get a different one.

[@dylanbrixey9913]

They can be ten bucks on amazon

[@pauls5745]

i think even better than the pinch mount adapter is to use a disc brake wheel, mounting the sprocket most securely in place of the disc rotor

[@joshuadulaney5559]

2 each there own, rag joints are working fine for me. I do have mags with screw on 1 way. Have 2 sets of mags still using spokes and rag joints without problems tho. I heard those adaptors r expensive and have there own issues. Idk no problems going with rag joints.

[@sandworm3]

I did the same thing. Did my research and people said the rag joint and spring tensioner is crap so I never even used them. My adapter slipped (used some different materials as a shim and failed) and messed up my spokes. Problem is that I bought a one inch hub adapter and my hub is just barely smaller than that. Thus right now I am grounded and considering mag wheels or fixing the current rim and really working hard to engineer some shims so it doesn't slip again.

[@shtboxgarage]

Bike Berry did a video on what you need to do to the hub mounts to make them work. Have to shave a bit off one end of one half so it clamps tighter and make a keyway in the hub & hub Mount. I'm sticking with rag joints as I don't have the tools to machine all that. I have one of those chain tensioners tho, they are phenomenal

[@eduardodiaz5762]

Wow that idler pulley is the Original junk Idler, that has very high chance of snapping a chain. I have the newer idler but it's still snapping chains, I'm going to upgrade to the HT Spring Idler like yours that chain looks flawless.

[@thebrokeway9838]

I put this chain tensioner on and it makes the chain bounce just a little. so on start up the motor throws the chain forward for a split second and with those two motions combined at just the right time it locks the chain up in that curve in the sprocket housing and it flipped me of my bike

[@MarkBaldridge]

I just took the tensioner off. I cut a couple links out of the chain and it's pretty snug. Also: You don't want your rear wheel REALLY crooked, but you can get a few mm of tension adjustment just by moving the wheel on the frame.

[@sparkiegarage8083]

The sprocket hub adapter kept slipping for me

[@dab-pre-ss-ionaustin1986]

Lol I did have the problem with the tensioner going towards my wheel but after I tightened it up more it went better but I'm also still using rag joints but I just ordered the adapter and new tensioner can't wait for them to come thru

[@mijanngellerman91]

Love all your opinions except the standard tensioner works great if you bolt it into the frame and the further back its mounted the less binding. I've tried both ways I still recommend a spring one but I have a problems with chains jumping on the springs

[@zedee2000]

On my motorized bike on the top chain after about around 2 inch of slack or more top drive chain in middle. I try to periodically check this measurement before riding. I knew I should have tightened it before I took it out but you know how that sometimes goes when you want to go riding. the chain jumped off the first time then the second time from chain too loose come off and binded up I replaced it. But I find if the drive chain I'm speaking of is too snug it's very hard to pedal. The looser chain gets the faster you can pedal it. And I'm sure this goes for the pedal chain too. And I have the stock flat wheel chain tensioner non spring loaded. About how much slack did you have in the top chain when it jumped off if you noticed?

[@WTR-mf8ki]

Agreed. I have rear mag wheel sprocket is must Spring tension yes must have

[@Shyzah]

the original rear sproket is not useless been running it for 700 miles no problem i off road with the bike and do city riding for fun.

[@thenivoldoog]

Nice video... I did end up ruining a back wheel when the chain tension-er ended up in my spokes on my first build.

[@burnt_toast305]

I baught the same chain tensioner for my motorized bicycle and I love it. The only thing I don't like about it, it's the roller that come it. The chain comes of when you ride and sometimes you have to put the chain back on which is so annoying and worthless. Please change the roller and put on the other roller that comes with the stock tensioner, that way you have problems with your chain coming off. I hope it helps for someone who have the same issues that I have

[@burnt_toast305]

I meant you won't have problems with your chain coming off with changing the roller to a stock tensioner roller.

[@SecondComingTwice]

I'm going to use the original chain-tensioner that came from the kit from China, but use taut -twisted copper-wire to ensure placement, and polish the wire before clear-coating it. Yeah, all my bikes are "art-bikes." The new Krylon 'color-shift' paint is da bomb if you have a bag of graffiti tips lyin' 'round yer flat.

[@eduardodiaz5762]

I got the same tensioner but with a gear Roller not the plastic junk. It still falls of but due to my tire being too fat and the sprocket being unaligned. I'm going to fix that tonight, but other than that I love the difference its semi easier to install too

[@jimmyvara1550]

[@JamesNickersonThePhotoShopGuru]

Thank you, great video, I am off to get the sprocket adapter and chain tensioner ... 👍🏻👍🏻🙏🏻

[@nathansmith3608]

sprocket adapter and spring chain tensioner FTW! I have a similar gas bike style rear adapter. interestingly, it actually works put on either way because the recessed side allows it to sit further onto the inner Hub so the space and comes out almost identical either way you put it - although I still prefer the way shown in the video where the bolts are flush, so even if things start to come loose you've got less chance of the bolt shearing off against the freaking coaster arm or something like that. rear sprocket adapter is one of the only parts I assemble with Red (permanent AF!) Locktite so it lasts at least a couple thousand miles. Blue Locktite it the first time though, and it'll last you couple hundred miles unless you tighten it too hard or too weak next upgrades on my prefs list could maybe be expansion chamber and Sturmey-Archer front drum brake or disc brake

[@robertsmith5323]

when you say you use red Loctite, do you mean between adapter and hub to prevent slipping? or on the adapter/sprocket bolts to prevent loosening?

[@stevensherman1802]

U just have to make tensioner really tight and that should stop it from going into spokes that what I did no more problems so far but I did order spring tensioner off ebay.

[@codelicious6590]

Looks like you got that chain lined up straight- that's so important! In my opinion, those xxhain tensioners are waaay over priced for the materials they're made from its ridiculous. People reallyneed to be wary of parts for these on the internet; make sure to shop around for Everything you're looking for cuz there are a wide range of qualities and costs and the kicker is that those two do not always match up!

[@martinlicht1969]

Bet an upgrade exhaust would get you a couple more miles per hour. I've always had best luck never needing a chain tensioner..but if you must..that one looks good.

[@mrbungle6505]

right on , built a mongoose fat tire, this is a must, for the build, even I'F I built a regular run of mill bike I'D still install, them coggs made of rubber is a death sentence

[@jasonjohn2395]

What is the best chain tensioner there is for a 4 stroke that's similar to this one in the video?

[@dennisleger3398]

rag joint if done properly is the most solid in my opinion. Those hub sprockets bolts love to unscrew its so friggin annoying. Even with locktight!!

[@carlseiz1266]

The other rear sprockets not dangerous it's just a pain in the ass to install I know from experience I wish I had the sprocket you had right now it looks so much easier to install and it looks way better

[@adoriusthomas3286]

Thats a lie if your using a old bike its dangerous like poeple dont have money to buy a 98 dollar huffy cranbrook lol

[@connorbarnedt7687]

If your having problems with top speed I would definitely invest in an aftermarket exhaust

[@DogsaladSalad]

That tensioner is 100% necessary. I use the rag joint though lol

[@DashzRight]

Very useful video, however I don't share the same thoughts about the hard rubber adapters for the sprocket, the 2 stroke engine is not soft in normal use there are more pulls and push to the chain than we may think, this can punish the bearings inside the hub of the rear wheel so the stock adapters act like dampeners between the transmission and the wheel itself, they come with lock nuts and lock washers which will never fall off, as I said its just my theory. I drilled a hole in the middle of the chain tensioner between the tube of the bike and the 2 14mm screws, it works amazing, Im thinking about building a homemade spring tensioner since I can't find one for less than 40$ which I think its too damn expensive for a metal piece and a spring...

[@lezenfilms]

Just get a piece of metal, drill three holes, one middle and two on either side, put a bolt through the mid hole and put where the tensioner went. On the left put the tensioner wheel and the right put a spring pulling towards the bike

[@cbgreenbay]

Yes that's exactly what I did . Except I used half an old brass door hinge for the metal and just cut off the part that the hinge pin went into. Maybe you got this ideal from my video ? Idk .

[@aculasabacca]

Iv'e seen the stock tensioner fall into the spokes. Iv'e also drilled the little set screw to hold stock tensioner. The guy that bought the bike with the set screw forgot to pull the clutch at a stop and the frame bent where we drilled the hole. If you are 200 pounds think about heavy duty rear wheel, If your 250 think about a 29 inch bike.

[@codelicious6590]

Beekibye YES! Exactly my thoughts! They sell those for way too high because they know there are only a couple options out there. There is Tons of DIY creation space in the motorized bicycle world and people just need to start developing new and better ways of doing stuff then sharing that knowledge on the webs so everyone can benefit from it! We dont need to give those Chinese corporations any more money than is absolutely necessary.

[@WTR-mf8ki]

True talk a agree must have for sure 👍

[@zedee2000]

For all you guys that want to turn max speed top end. Record max speed, then loosen up your drive chain record Max speed again, for me it seems on my 4-stroke motorized bike top chain slack measurement is in the middle of chain. measured with tape measure is about 1.250 - 1.750 is where I run the best at pedaling that is. when I snug up the drive chain more than than 1.250 I could barely pedal the bike at all. because it has more resistance and I'm sure that goes for the pedal chain also. Loosen your chains before and after and check your top speed and give us some feedback. And I think when I let mine go a little too far on the chain slack on the top drive chain in the middle it was about two inch or a little more when it come off the first time and the second time it was within chain slack spec. but it come off so I replaced with a new drive chain. Chains will get worn with time and stretch making more chain slack, so periodically you'll have to tighten it. And at some point you'll have to move wheel all the way forward, move engine back toward rear wheel, put chain tensioner all the way down and then take Link out if needed and still have enough chain slack. Before I installed my chain I soaked it in oil a few days before installing it.

[@doomracing7769]

You can always drill threw the chain tensioner and chain stay to keep it from moving. I prefer the tensioner shown in this video.

[@greenmachine55]

To get more speed you need to upgrade more smaller sprocket tooth count gets more speed but also to get better performance from your engine get a boost bottle and the intake for the boost bottle line to connect too and replace the stock exhaust with an expansion chamber exhaust also a higher performance cylinder head instead of the stock one it came with for better compression and better flow

[@derrickcarroll4932]

[@kigykabark154]

the most important upgrades are to put a long tailpipe that reaches the back tire and the carb that you have. I mounted a motor on a chopper bicycle and did not have to use a chain tensioner and the rear sprocket that came with the motor works fine. the motors should never be put on a normal bicycle to begin with they are made for high quality beach cruiser bikes and chopper bikes not BMX or mountain bikes

[@kamilb.5758]

chain tensioner is a must have, that's for sure ;) however that sprocket mount is too stiff, makes your ride twitchy, you loose a lot of smoothness, believe me

[@cbgreenbay]

Oh it will be real smooth when your spokes bend and break and the chain comes off and locks up the back wheel . Because the last thing we need is something stiff or solid when it comes to rear drive sprockets LOL. The only thing I noticed when I switched was the peace of mind I had knowing that my sprocket was secure and not damaging my spokes anymore .

Nice build, very informative on the parts, I'm building a 79cc predator setup, the engine is mounted on the rear rack, 12 tooth top gear and 48 tooth on bottom, using the maniac hub system, they are a blessing, this using a centrifugal clutch with a high end #41 chain, looking for quality chain tensioner, your setup won't work on this build, this a brand new Trek 7.1 very light touring bike, I'm hoping to reach 35 mph, I had a Station Chain friction drive kit with a high end Zenoah 43cc two stroke engine on it, sold as a kit by station, very high quality, it could reach 31 mph, not bad for a friction drive.

[@rimshotrecluse9345]

+sc1212able Thanks man. Yeah I don't know where you might find a good tensioner with that set up. I'm working on a skyhawk build from the frame up right now but my next build WILL be a four stroke. After jetting my carb on this set up I was able to hit 32mph and I'm 240lbs using a 44t sprocket. IT made a real difference in overall engine performance just with the right size jet.

Well a bit over a year into the engine and I've managed to break 2 engine mounting studs so far.

Then I plan on getting that new idler pulley setup you are using as well as replacing that rag joint setup. Other than the engine mounting studs I haven't had any issues out of my engine. Its a pain to start after it sits for months on end, but once you get it going it runs great...tops out at 25mph and I've only got about 160 miles on it.

been think of buying this bike and riding it as a pedal bike. is the bike alone any good? i am 6'2" and 210 lbs. think it is too small for me? any thoughts would be appreciated. i can not find any reviews on this bike that is why i am asking you. thanks in advance.

First time I put that garbage stock tensioner on, it turned inwards on start-up. Complete destroyed the spokes and rim

Is that adapter better than the 6 hole hub adapter?

I want to get that chain tensioner setup this is the best setup yet you said you can only get it off Ebay?

I agree those rubber rag sprocket adaptors are junk. I am 63 years old and have been a professional fishing guide since 1976 so I build these motorized bikes to leave at the boat take out for the end of the day when after using the drift boat to fish a long stretch of river then use the bike to get back up the river to get the truck & trailer to come back to the boat launch take out to load the boat. I don't need speed I just need reliability to get back up the river to the truck and boat trailer which could be a 10-mile motor bike ride and ride just before dark you don't want to peddle a bike the 10 miles. I have one bike with a 212-predator engine and a second bike with a 2 stroke 80 cc motor.

Chirs Burkett Nice!. Where did you buy your sprocket adapter?. Thanks

[@lemuelleequinones8575]

first thanks for the video I do agree with you in both of this items. I have a question as for the carburetor, I noticed that you are using the stock exhaust, did you re-jet the high performance carburetor and if so what size jet are you running? I ask you because I tried one of them with my 80cc and with the stock exhaust it would choke, after putting and expansion chamber it still does, not as bad but I choose to take it off, because it was still choking. Something else that the sprockets guys make is the rubber motor mount, these are nice also.

sorry for the late reply man. I did rejet to a .64mm. It's a little cold blooded with this lean of a jet but once it warms up it runs great. These carbs are limited in tuning to either jetting or the idle adjustment screw. Chances are you will not have perfect throttle response from idle to wide open throttle but a .64 jet was the best overall for me.
