What a great idea here a regular genius and you're creating exactly what I was thinking

Hey friend, thank you so much for this video. You are about to save me a lot of money and trouble. Really grateful.

Thankyou hutch! I have been looking for this for a long time!

excellent work brother, the simplest and greatest setup i have seen yet..

THANKS again, I'll keep that in mind. Have a great weekend.

That's what i'm looking for, brilliant trick of Diy freewheel crank, thanks for sharing

Nice idea! As a bonus, with the loud clicking from the freewheel there is no need for the old trick to put a card brushing against the spokes for nice sound effects. Sorry it did not last.

Lovely. I need something like that, but for a slightly different reason.

Thinking outside the square. Great work. 🇦🇺

Parabens magnififica ideia, OTIMO PROJETO, nao de ouvido aos comentarios absurdos , sempre virao em torno de algo belo, um abraço do QUERIDO BRASIL

Nice job. Thanks for the great video

Great job. thanks for the advice

Brilliant Video, Helps a lot man!

thank man this is exactly what I was looking for

Brilliant just what ive been looking for to solve a problem i have

This is good stuff man! You need "sleeve bolts" for the smallest chainring, and really some sleeve tubes made up on a lathe instead of that stack of washers. But at least you were able to make it work with basic bits and pieces. Good job.

Nice job!

Very creative! Thanks for sharing it with us! Btw nice channel

that is what gonna do for my motorized bike thanks that is simple was looking for a way to do it.

awesome video this will help a lot

I'm glad to see some one has the same project like mine. But I'm sorry that this project was done 8 years ago.

great idea !

I was having problems understand this type of setup until I saw your video, Thanks for the help. Could you please explain why you used a 56t sprocket instead of say a 44t, more power or speed and what where the bolt sizes and length did you use to put it all together.

Thanks for yor quick reply. That will help me alot. So if I understand you right, by going to a smaller sprocket I'll gain speed, but lose power for climbing hills. I'm planning on using 24 inch rim & tire combination which would give me more hill climbing power. So how do you think your setup would work with the smaller rim & tire.

Good job

Your videos were great! I have to commend you on your effort and the genius way to create a self powered E-bike compared to those other videos on here that are a waste of time. Can you tell me how much it cost you to buy everything including the batteries and controller and so forth. Complete how much? Thanks

If you start welding, there is no telling what you might create!!!! I started my adventures with a 100 buck wire feed welder at Harbor Freight.

buen video mui claro y consiso sensillo de hacer gracias

I like this setup and am wondering if it will work with a mid mount e-bike motor with a bolt on jackshaft for a gas engine to make a hybrid bike? Can you let me know if this would work

Great vid thanks! Maybe someone has a asked this but, how does the drive from your feet transfer to the back freewheel? Like it looks like the crankarm isn't connected to the chainrings. Maybe I'm missing something.

thank you very much ,learned alot

Good video my friend...

Thanks for responding so fast. The info. you supplied helps quit a bit, but you wouldn't happen to remember how long the bolts were that ran though the drive gear and 8 washers? Have you done an updated version of this project. Thanks for the help and keep up the good work.

Thank this is what I need to do diy ebike

Where did you get the special crank arm? What would be a good source for the small motor that will drive this? Where did you get the motor from?

Tankyou

This is a good idea. I read the comment that it failed but it just needed some machined blocks maybe from some 6061 aluminum to make it solid. I do have a question being that you seem to be skilled in building motor bikes. Has anyone used at least a #40 - #41 chain n sprockets ? I ask because I'm a good sized feller who is 6ft + and 200+ lbs and have stripped several bike sprockets just by peddling up hill. My goal before spring is to build a 99cc or 212cc predator with maybe a 3 speed drive the way you have done here. I'll belt clutch a step shaft to drive the peddle sprocket but already know that a regular bicycle chain will strip out.

How is the drive chain and 56t sprocket holding up to wear and tear?

Hi I am thinking of buying a GNG kit but also thinking of a converted hub drive mid drive conversion so wondering if it is possible to build a triple free wheel crank off the shelf with quality products, doing research and kinda thinking of doing custom DIY mid drives in the future as a hobby.

extremely clever arrangement , how did it work out ?

I see sprocket to sprocket is lined up nice and straight. But when you tighten it up. It's not going to be lined up anymore. Will drop a good few mm. Did you put more spaces on to fix it. Just wondering because looks like. You don't have much room left on pedal arm.

chains wont hit each other if you have this same setup for left crankarm (and freewheel hub for left hand), which can also eliminate jackshaft junk for gas motors that have left side motor sprockets.

Nice concept! I want to replicate this. Ecospeed has a freewheel kit that could have worked for you.. Did you ever consider using that instead?

This is a 2 part question. 1: What size of washer did you use and how thick were they? 2: When you cut off the chain-ring mounting bracket did you have to drill the holes and if so what size of bit did you use?

I wonder could you share links disease things you used to make this with because I can't do anything with them myself with my inadequate toolkit of a couple screwdrivers and a pair of pliers but I'm hoping to enlist the help of somebody like you to do the parts that I can't because I desperately need to get this done and get back to work

Hey awesome setup, so I understand the crank has a freewheel built in on the right side with all the chain rings so when the motor turns your your pedals stay stationary, so is there a freewheel built in the left side, I got a project right now, i converted a car alternator to brushless motor

That turned out really well for being drilled free hand :) . Where did you get that threaded crank arm?

I really like what you have done with your mid drive system.. how has the 250 watt motor worked out and do you know where you can get a 500 or 750 watt motor to use as a mid Drive the same that you did. I really like the commercial Baufung mid Drive kit which includes battery for about $1,200 but I don't want to spend that if I can do something similar that you have done

exelente

Where did you purchase the triplechainring set?

Btw I would love to see a video of this in use with the type of setup that I was asking about because if possible I would like to make one my self as I am an avid diyer and outdoors man it would be very useful to get to where I hunt and use a small trailor to haul game and hunting equipment to and from the woods also for going to the store, ect. So I can really use the information.

lo que le pones en el sentro es un espro y el braso le hisiste cuerda mu pudes contestar la pregunta gracias

can you do an update video?

Where did you get crank arm with thread?

Wow pricey so what is the advantage because I saw a front wheel E-bike conversion kit on Ebay 48v 1000w for under $200 includes wheel with motor attached with spokes and controller and throttle and so forth but does not include the battery.

great video... I'd like to see the second video where is it?thanks

Ya I was talking about two fro the chain drive and one for the drive. Problem is most of them are crap, not impressed with Cyclone and want something that looks good, Looking at GNG kit right now but would like to build my own possibly using parts from sickbikeparts..., I want high quality and buy the time you get the parts from china your better off getting local parts. Also thinking custom high end builds. . Read a few posts with the crank threads stripping on GNG kits

Okay so what is the maximum speed I can achieve on flat road? I am looking for at least 28 MPH. Thanks

the freewheel doesnt rotate in the backward position right??

Do you have the video of removing the original sprocket from the motor? Would appreciate if you can please share the steps to remove the sprocket from the motor.

How many mm is that crank arm and where did you buy that threaded crank arm?

so since you have a freewheel, does that mean you can no longer use the pedals to move the bike?

now that was bad ass! fucking sick! got a part 2?

Where did u get those little brackets for the 22t ring ?? and what material are they from ?

hi man, please tell me the exact name or where can i buy this freewheel that is adapted in the middle of the crown? I didn't find it on the website mentioned in the description thanks so very much.

Is it possible to use this combination you made in your eletric bike, but instead of this eletric system i use similar to the sbp shift kit? well, the truth is: i live in Brazil , would be hell of expensive to import the sbp shift kit. (or any other kit of the kind) i have a 2 stroke engine kit on my bike and was planning to make a homemade shift kit, also using this Crank ideas of yours.

Hello hutchtransfer, can you tell me what type of bottom bracket are you using? i am building one but there is no space for the triple chainrings. Im using a 153mm bottom bracket. Can you help me?

👍👍👍☝️

Where did you get the freewheel?

which store or online would sell pieces to change bike pedals to freewheel?

Were can you buy the crank arm with the thread

Many of these mid drive systems are noisy because of the small sprocket and chain. Could you demonstrate the noise level?

What happens if you get your trousers/pants caught in the drive sprocket ? Is it gonna rip your leg off? Like you see on those lathe accident videos

What I men't off the shelf, not grinding or drilling just get the parts and assemble.

Very nice! Does anybody sell a pre-made set like this?

can make a tutorial of zero , because I'm from Venezuela and is hard to get something and import is way too expensive

Interesting, are you the same person as cryptopyro here on KZfaq who also made a triple chain wheel?

where did u get the 56 tooth drive sprocket

buy the complete freewheel chainwheel crank set is cheaper and easier

tell me more about this.... please

where did you get your crank with threads ??

Given the rear wheel already has a freewheel, by making the drive sprocket freewheel-enabled, how is efficiency achieved?

Hey there I really like your video. It was very helpful. But I was wondering is there a way can I pay you to make me one?

where i can bye this crank wheel in india?? please suggest mi???

can i buy one thats like this but not homemade and if so where can i get it

I wasn't suggesting the chain would fall off. It's just it seemed a very basic thing to get wrong whereas in other areas you have obvious skills. I will check your other vids, i'm not usually critical of people but I was shouting at the video when you didn't drill that thing accurate hahaha

Hmmm. . Right at the beginning there when you didn't drill the holes accurately I was disappointed. Surely you could've spent an extra 20mins & a simple home made jig to get them accurate. Even with a hand drill you can drill them small & file to correct them. Anyway keep up the good work.

Im buy

Any updates on your work?

01:20: Sick bike parts?

If I'm off a couple thousands, I say, "Good enough for government work."

buy all this from cyclone built for about the same cost

hello I am from Italy, I would buy this item, could you help me? send in Italy or know a site to buy?

Hi. Meaning no disrespect, but all of these extra gear ratios are totally unnecessary. You have 8-10 gears on the cassette. With 3 extra sprockets on the chainring, that makes a possible combination of 24-30 gear ratios. With almost any bicycle engine, from the China Girl mid-frame engine to the GP460 or Tanaka 47R engine, 8 gears is more than enough. It'd be like driving a car with 8 forward gears. And YOU want to drive with 24 forward gears? Really? I've run both the 460 and the Tanaka engines for over five years on crowded streets and highways. Guess how many gears these engines like, for street driving? They like FOUR GEARS!!! First gear to crawl on sidewalks at walking speed, third gear at Olympic runner speed, and 5th gear to jump into traffic at 30mph-up. And one thing ALL!! 2-stroke engines like is SUPER LOW GEARING to start off at the bottom of a steep hill or a dirt berm. I run a 10-tooth engine sprocket connected to a 72-tooth chainring sprocket(T8F/smaller chain= 7" chainring sprocket). The engine has a 5:1 reduction tranny, so that's (72/10)X5=36:1 ratio. Then I use a 24-tooth driving chainring and a Shimano 11t-34t 8-speed cassette. So 36:1 x (34/24)=51:1 first gear! That's like having a 123-tooth giant rear wheel sprocket! So as not to bore you with 8 gear ratios, here are the other 4 gears that 2-stroke bicycle engines might like: 3rd gear on the cassette is 34.5:1(like an 83-tooth rear sprocket. 5th gear is 25.5:1(like a 61-tooth rear sprocket. 7th gear is 19.5:1(like a 47-tooth sprocket). If it's flat ground, I might use 8th gear, which is 16.5:1(like a 40-tooth rear sprocket). If I use the first 4 gears in a row, my engine says "Come on! Shift wide-ratio, not close-ratio!"Okay, let's try to figure out what your gear ratios would be like on a bicycle with a China Girl engine. Let's gear it very low on the engine and jackshaft, to give you a fighting chance of attaining ho-hum gearing to absolutely un-usable gear ratios. The China Girl engine has a built-in gear ratio of about 4.15:1. Take a 10-tooth engine sprocket and chain it to a 17-tooth left-side jackshaft. So 4.15 x (17/10)=7.06:1gear ratio. On the right-side of the jackshaft, place a 9-tooth sprocket. Chain it to the 48-tooth chainring. So 7.06 x (48/9)=37.65:1. Connect the 34t rear cassette to the 24-tooth chainring. So 37.65x(34/24)=53.34:1! That's like having a huge 129-tooth rear wheel sprocket. Really low. To be fair, this is even lower than my setup. 8th gear is 17.26:1(like a 42-tooth rear sprocket). A 2-stroker would love this combination.Too low and need more speed? Ok, shift to 36-tooth chainring. First gear is now 35.56:1(like a 86-tooth wheel sprocket and 8th gear is 11.5:1(like a 28-tooth sprocket. Unusable for 2-stroke engines). 7th gear is 13.6(like a 33-tooth in-usable sprocket). 6th gear is 15.69:1(like a 38-tooth rear sprocket).Need high speed? Can your engine pull these high gears or fall flat? Switch to the 42-tooth chainring. First gear is now 30.48:1(like a73-tooth rear sprocket). 8th gear is now 9.86:1(like an un-usable 24-tooth rear sprocket.7th gear is 11.65:1(like an unusable 28-tooth rear sprocket. 6th gear is 13.45:1(like an unusable 32-tooth sprocket).So, with 24 possible gear combinations, which do you choose? If I was FORCED to use multiple chainrings, I'd run the 24-tooth chainring. 8th gear would be 17.26:1, which is fine. However, if my engine had the power to reach 50mph, I'd switch to the 36-tooth chainring. I'd do this for the sole purpose of using 6th gear, which is 13.45:1(like a 32-tooth sprocket. For further comparisons, let's use stats from a gear ratio calculator:to be continued while I retrieve the gear calculator link.....Read more Show less Reply 1 Edit Delete myron yamashita1 second agoOkay, 8th gear at 16.5:1: a China Girl spinning 9,000rpm would reach 42mph. A Tanaka engine at 10,000rpm would hit 47mph. A GP460 engine at 11,000rpm would turn 52mph. So my whole point is that you don't need more than 4 gears.....8 speeds at the most. Choose your sprockets wisely for super low gears on 2-stroke engines. If not, you'll be riding a dog.Read more Show less Reply 1

mate! if you can make these, id buy one, i need one, but dont charge four hundred for it ffs

.

I say it's a fail considering that big gear is supposed to spin free from the others

Would you be interested in selling one for a reasonable price? I don't need a triple I just need two change rings with a space where the middle one was leaving me with one for my existing chain on the outside that goes to the back derailleur like normal and then another one on the inside for the short chain coming from a DC motor located in the bottom of the triangle for a DIY mid-drive on the cheap not because I'm a cheapskate but because I'm unemployed and this will be my primary mode of transportation for now until I can find a decent job and save up enough money for a car that doesn't force me to deal with ghost pedaling and allows me to Leverage all the benefits of the so I can get the most bang for my buck out of this little Walmart hoverboard motor I have that I am misappropriating specifically for that purpose which as I see it is by far my best option for an affordable conversion of my cruiser hybrid to make it as efficient as possible considering I'll be using old 18650's from obsolete laptop batteries as my power source which leaves a lot to be desired but is barely within my means as it is assuming I can get it done as I simply don't have the materials or tools necessary to fabricate this part

Update¿

it's not homemade
