6 Chain Tensioners Tested | Motorized Bicycle | Bike Berry

[@mikesbarn1858]

Great information as always. In my experience the tensioner should always be mounted for the bottom chain. The top part has all the engine torque on it. Second the tensioner should be mounted as close to the engine as possible to minimize deflection. It puts less strain on the links. Finally I love the versatility and security of the arch tensioner

Tony. On some of my builds I have used an Industrial rubber torsion tensioner, available from my local Industrial Supply store. make mounting brackets to fit the position on the frame and use the stock guide roller. Once positioned, tensioning the chain is easy. I note in your video and others that I have seen, spring tensioners, the spring tends to resonate. This does not happen with the rubber torsion one. I have not had any issues with the Kit tensioner on any of the 23 Motorized bikes that I have built. I have seen the tensioners improve in quality from 2014, when I started. The first ones the guide roller did not have a bearing. The latest kits with the double bracket and angled adjuster are the best. I replace all bolts and nuts that come in the kit with High tensile cap bolts and nuts with proper steel washers. .

[@tonytaylor5087]

Well thank you 😊

[@DG-fe4ht]

Wow great video! I’m on your fb page and recently posted my homemade “X factor” … took heat for drilling small holes in my frame, but it works great. Thx for all the hard work you put into this hobby!!

[@tonytaylor5087]

It’s great to have you in the group! Appreciate the kind words!

[@stephenfhauk]

I have tried 4 different tensioners and found only the Arch tensioner to be truly reliable in design. The spring tensioner that I bought for my friends bike pulled the bearing through the mount and failed within 1 hour. The stock tensioner with the 2 straps stripped out the bolts and nuts before even getting tight. I even tried a small tack weld, Unfortunately the tensioner itself bent due to cheap metal. Cool video though, I like that you tried so many of them.

[@andrewgonzalez4230]

Yea the bolts are like a soft aluminum. I ended up going to local hardware store to get better quality. I had to cut a bolt off on the rag joint it was stripped so much.

[@panzerwolf494]

Best one i ever got was just like the bare bones spring type like the one in your background at the start of the video modified with some other parts. I work in a steel stamping shop and we used to run a part we called the boomerang because it looked like one. It had a few holes punched into it that when the part was bolted to the bottom and top bars of the frame the tensioner arm could bolt on and the spring hooked into a hole on the part. There was another hole I fed a bolt through so when turning the bike over the tensioner arm would stop stretching all the way down, but still had enough clearance to function while riding. Never had an issue with it

[@kevinw2241]

My thoughts.1st of all many thanks dor your video. Im in the process of finishing the assembly of the F-zero bike w/ S4 engine taking my time dor about 6 months now. Taking my time by choice only as i am often enjoying and wrenching my Chinese enginered 200 cc ATV. The #3 case mounted tensioner you stated that on ruff terrain the chain will jump off the spured sproket and its not meant for tight tension. I actually was thinking the same thing while watching the video before you mentioned this and was thinking instaed of the spured sprocket why not replace it with the smooth walled sprocket from the one that came with the engine kit. I have the case mounted tensioner that arrives yesterday and will attempt to finish the assembly with test runs today. I will try both sprockets starting with the original spured sprocket afterwards will be the smooth walled sproket i mentioned early. I will post my results when completed. But please dont hold your breath waiting for my results. This will be completed as soon as time and the days events will allow.

[@LaCourierInCrysis]

I've done em all and customized them by changing the mini sprocket for a wheel on the case mounted ones. I like the duel wheel and arch without mini u-bolt

[@earlgarcia9824]

I would recommend beefing up those springs that come with the tensioner they're to thin ,I've used motorcycle kickstand springs, they don't bounce around so much.

[@JosuePineda-lz7jd]

Great video thanks for yout time ,I have tried several tentioners ,for me,the arch tentioner is the best ,I aded a second puley ,so is mind free ,

[@Crashwithabang]

I used the nice billet one and just drilled a hole on top of sprocket cover right under top bolt for the spring. The angle of spring and additional tension remedied the centering and spacer issue. I also changed gear to a plastic roller and it has MUCH QUIETER mesh and resistance. Thanks for all your videos and advice....Have a GREAT HOLIDAY SEASON!😁 PS, I can share a video or send you a pic if needed.

[@danbrownellfuzzy3010]

Just from eyeballing it I would say an ideal setup would be a tensioner very far forward and an additional one very far back. Tensioners seemed to be all designed with a monoshock frame in mind where perfect alignnent under extreme conditions exist. I just went from a stock one to a simple three bolt case mounted, only because failure of the stock one would throw it into my rear wheel. Im only taking her on asphalt and i keep my speed down.

[@LycheeChudha]

i thin arch one is good but on the top the also need spring tensioner much better for long time no trouble ty

[@dogswhistlesharam9029]

I ended up not using them as I wasn’t impressed with the quality, I ended up fitting a Jack shaft kit, and now I have x8 gears to use with the motor, a far better upgrade , use a stronger e-bike chain and you have to replace your rear sprocket set more often (which is understandable).. It’s best if you have the centrifugal type clutch for this set up and ease off the throttle when shifting gears..🤔

[@tonytaylor5087]

I’m interested in the jack shaft assembly.

[@bryduhbikeguy]

It sounds good.I'd like to know which brand you used.The 1 I'd saved to my 'Wish List' isn't available anymore.Thanks.

[@edj9202]

How do I assemble the billet spring chain tensioner mine came disassembled and I don't know where to place the bearing and the plastic wheel..

[@N9197U]

A quick note, make sure the chain tensioner runs parallel to the chain! on my beach cruiser, I had to bend the main plate in a vice to get it lined up, and it works flawlessly.

[@kimdecastro9156]

great video . the last chain tensioner i guest you can't youse the chain guard ?

[@shadlaflure262]

Good stuff Tony great content very informative....

[@drohrstestes]

My experience with the arched chain tensioner is that if you don't go fast enough to start the engine and engage the clutch the kick back from the engine can bend the crap out of the arch tensioner. It seems that these are made from cold rolled steel and the metal is very weak. At least the one from BB is. That's where I bought mine. I don't use it since it's garbage now. Just something to be aware of. Tony - i noticed your black arched chain tensioner is thicker than the one BB sold to me. Where did you get it?

[@N.S.F.C]

That double tensioner is secure. I really like the arch. I would want to weld it on the frame. ( bummer I cant weld aluminium.)

[@JO3BID3N-is-a-P3D0]

i think ill go with the arch one. thx for the vid 🤙

Links to the chain tensioners

[@tonytaylor5087]

Yup, I added them in the description! Thank you!

[@kobematthews24]

Don't use the cheap bolts that come with it! what I did was went to my local hardware store, match the size of the cheap bolts, to get reliable one's, sturdy one's, brass works extremely well. machine nuts and bolts. you literally can replace them all for under 4 dollars! Very cheap but will leave you with one less headache, thank me later!

[@andrewgonzalez4230]

I did exactly that. Them bolts that come in the kit are pretty cheap and strip out with no effort. The lock washers were even popping out.

[@apexseeker3821]

I’ve seen some builders eliminate the tensioner altogether and just shorten the chain. Is there a downside to that other than when you need to remove the rear wheel you would need to remove the master link.

[@JO3BID3N-is-a-P3D0]

maybe when your chain needs tightened. when it gets worn out and stretches the tensioner would be nice for fine fine adjustments

[@jonathanwilson1380]

stock tensioners worked fine for me when its used properly on an oval chainstay, i did blow up a wheel once when i had rubber between it on a circle chainstay.

[@tonytaylor5087]

For sure.

[@POSTALHIPPY]

I have a friend who refused to use one but also throws the chain often. What are the repercussions of not having one?

[@timothynance9827]

Hey Berry that bike behind you in this video is the kind of bike I want to put my moto on with a 32 tooth so it will run better I have it on a rock creek huffy 18 speed and it won't run faster than 28 miles an hour and I want it to run faster like 45 or 50 miles an hour.

[@erasmosilva3424]

Espetacular!!!🇧🇷

[@nygivenpoint]

How did you fit sprocket over disc brake mount?

[@shtboxgarage]

Looks like the sprocket fit between the disc brake and the spokes. Intriguing

[@TheCrazzyToobinator]

I find this to be the hardest part of getting these engines set up especially if you have a small frame. I honestly love the idea of that curve tensioner, it is the only one that looks reliable. I have tried the spring tensioner and the stock one and both do not really work for my set up and I now have damaged spokes after having the chain drop off too many times. I think best of both worlds would be to design a tensioner that is both adjustable and uses a spring but uses the same mounting as the curve one so that it always keeps the chain where it is supposed to be.

[@Bransomware]

Agreed

[@kennethlloydr.sentino934]

Brother can I ask what the size of your disk brake adapter is it 203mm by 180mm?

[@stelthcamo357]

Hey Tony I have the case spring that mounts on the engine only problem I'm having is the long arm that the the spring and pully attach to keep coming lose making the arm flop what can I do to keep the bolt tight so I don't back off

[@survivalishardstaystorng]

Just get rid of the slack in the chain all together you're probably wondering well how can you do that if the links are only so big you take one out too many it's too small too tight you put spacers on the brackets for the motor mounts it's adjusting the motor itself you can move it forward slightly if you have the room inside your frame you'll be able to move it forward and maybe even slightly up this will take your slack out of your chain eliminating the need for a chain tensioner eliminate as many moving Parts as possible on any type of machine and you will have less room for error and breakdowns simple is better.

[@MrCbell57]

Hardly ever can you work it out to not need an adjuster. Just saying. IMO after building dozens.

[@jacobboyington6606]

​@@MrCbell57 right, slack will always return

[@cressonhorton7982]

I got a new motor kit, 50mm board out. I was running my bike with no chain tensioner for a long time with no issues. Now I have to get my chain about 1/8-1/4" out away from the new brackets for clearance. My thing is the new chain is longer and I'm not sure how many links it should be cut at than completely right fit, I was told about half inch longer?

[@midnightrunner684]

My original chain tensioner that came with my engine kit .Twisted and went into my spokes and tore them out

[@MikeNBikes]

Once I hit 25 mph it dawned on me that if that tensioner goes in my spokes I'm a deadman

[@Nostalgik64]

The best setup is two chain tensions. One right by the motor guiding the chain back into the motor and one right in front of the rear wheel holding the chain like a 4 wheeler does when it’s sliding on the plastic protector. At 3:17 you can watch how his top chain is bouncing everywhere that’s what the second tensioner does is hold that vibration down while the one by the motor is actually keeping the chain tight. Also please don’t be like this guy and just let your chain hit your rear wheel. Dangerous
