Thank you soooo much! I am building a motorized bicycle and my dad and I could not figure out how to put the coaster break back on and have it work until we watched your video. Thanks again so very much
So recently got a bike with coaster hub I tightened it too tight and destroyed my dust cover and bearing now here I am with new bearings stressing out because I don’t have a dust cover and didn’t know if I needed it to make the bike work thanks to your video I know now I can run it with out one thank you for making this video it helped me
Got a question and I can't find any videos on my issue. I am having a BITCH of a time trying to get my rear wheel to line up perfectly straight, to where the drive chain doesn't rub up on the rear wheel. How do I fix that issue? 3/4 of the wheel clears the chain, but when it's rotating I can't see and hear the chain rubbing when the wheel wobbles a bit while I'm spinning the tire. I can't fkn figure out for the life of me why I can't figure out a solution. I REFUSE to pay a bike shop $40 for such a simple thing. I should know how to do it and I don't and it's pissing me off. Any help or suggestions would be greatly appreciated 🤘🏽
Thanks for the very simple to follow directions. Most people simply rush through to the finished product. With advice and directions like yours, even a novice like myself can complete this project.
3rd motor in. completely tore apart 2 rear assemblies attempting to find out what every self proclaimed mechanic in my neighborhood couldn't seem to help with. (How the rear assembly works with a coaster brake). If I had found this video sooner I don't think the chain would have snapped off the second motor and the first braking mechanism would have worked out without replacing the 1st one. Now all I need is a video on removing the coaster brake without stripping the nut and how to re-center the inner parts so my chain isn't so close to the tire.
Good video , I used a wheel and ground down my dust cap and used it a s spacer over the motor sprocket and the brake arm clears the bolts and keeps everything tight while still protecting the bearings .
Thank you! I was worried that I put the dam thing together wrong and your video helped me see that I did do it right. I was worried I put the two little caliper pieces in backwards but now I know for sure I didn't. Thanks again!
Dude you are the mando you know I have watched almost every single video and none of them show me which way the brake pads are placed cuz I freaking tore me apart and forgot how that damn thing goes back together
you dont need to throw out your dust cap. You can dremel out the opening in the sprocket to be large enough to go over the dust cap and save your bearings.
Hughes motorized has a video about trimming the dust cover down so you do not have to automatically chuck it. It is not all that difficult to do, either.
i have done that before , you have to trim so much off its like you aren't using one anyway plus i never ride in super dusty offroad areas anyway so it doesnt matter
I got a question I just got a new hub I've done it before thought I had everything correct having a little trouble getting it to not have any play how much play is acceptable and I wasn't clear on which ones to hold the way you were moving the camera so much I would really appreciate a reply thank
I left the dust cap on and placed the new sprocket over it. I found an untraceable rubbing and chain not moving as it should. Now I see that I must remove it and rebuild. Any advice on which way the sprocket should face?
i normally face the sprocket out so the chain is the furthest from the tire i have had problems in the past with the chain eating away at the sidewall causing blowouts ,
@jumpa01 i think people know not to stomp on the brakes doing 40mph the bike will slide down and it will ruin your day thas why i sujest in other videos to put a cable brake on the front wheel for added braking also what is with the grease crack if you dont like the video fine i figured i would make the video to help make sure someone does not have there bearings fly apart on them from lack of grease dont blame me if you did something wrong be mad at yourself
Excellent explanations this is exactly what I needed to help me put my new wheel on. I used a coaster braker wheele on my mountain bike converted to a motor bike.
I have a 26×2.125 heavy duty tire it locked up on me and had a lot of wobble it does not have the star shaped figure messed up the tire thinking of ordering the same tirw how should i go about the next one i put on it?
you do have to bend the coaster brake lever to clear you need to toss the dust cover it will rub the sprocket if you dont these motors work suprisingly well on the 29" genesis onyx from walmart very mean looking bike my only gripe is you have to throw away the handlebars and buy smaller ones because the throttle doesnt fit the larger tube used on the bike
Hello just bought motor kit but have a 29er from wallmart im trying to use it on. Can you tell me if you bent the coster brake arm so it would clear the bolt heads? mine won't clear the bolts. or will removing the berring dust cover some how make it clear? any help with this I would be much greatful for. PEACE...
can't get the coaster brake arm to fit, I remove the dust cover,gonna remove the pads inside and put the wheel on and install front brakes,what you think, hey I am new at this ,I need a hobby,been work n on this a month now

Hi am putting my bike together. Am having trouble when using back brake, the motor chain is still turning the sprocket and back brake kicks back. Any help much apprieciated.
And leave it off ? No that is the only way your brakes can operate and without it the first time you forget and pedal back your brake will overtighten and your axle will either break , threads will strip or it will spin in place damaging your entire hub and probably the rear of the frame , i had the coaster arm center strip out once and thats what happened .
I have other brakes. I don't want the coaster brake. Not worried about that. Worried about fitting sprocket on back rim. Without the coaster brake working. So it will spin free backwards. Like you can pedals backwards with a freewheel.
sorry it took so long to get back to you this whole new comment system is junk i tried every day to answer my comments but the reply button didnt work its working today for some reason the direction of the sprocket realy depends of your bike if it looks like the teeth or chain will rub your tire or frame then you can turn the sprocket around to get some more clearance you can then use the tensioner to align the chain where the sprocket meets by tiping it left or right slightly to center the chain links with the sprocket teeth
just got in to this for a hobby, I got a huffy cranbrook got the motor and everything together,put the sprocket and hub in the back,could not get the coaster brake arm to fit, so I took it off and put the wheel back on ,have not drove the bike yet is it ok to ride
if the arm wouldnt fit what you need to do is bend it so it will fit , it is not a good idea to drive it without the arm attached unless you want to replace the rear wheel or end up going to the hospital it could literally lock up self destruct at any moment without the arm , every bike i have ever made needed the brake arm bent to fit after the sprocket was added , its annoying but necessary , btw nice choice with the cranbrook which one did you go with ? the black and green one walmart has now looks pretty boss
do you mean the hole in the middle of the sprocket no i left it alone you can open it up if you have to the guts in a stock HiStop coaster brake fit perfectly through the middle of the sprocket if you need to open the hole up you can file it or use a dremel to get the desired clearance
Hey man, building the motorised bike and I've got the default alloy wheels... but was planning on reinforcing the spokes with copper wire and solder. Do you think this would be much of a problem?
While it's a very interesting idea, the spokes need to remain tuned and flexible. The more tension you add to them the greater offset tune you are likely to face. I would recommend something like the 'manic Mechanic hub adaptor' rather than potentially damaging your spokes. It's all up to you, and if you actually follow through with the soldering project I would love to watch a video of it. Really an intriguing concept :) ~Mike
the coaster brake hub needs the arm to function properly it might work normally unless you back peddle at all or the brake is somehow engaged due to centrifugal force , in that instance your peddles will be forced forward and your hub assembly may over tighten itself since the parts that were originally stationary can now spin with the torque of the brake causing self destruction of the hub , i had a brake arm strip out once and that is what happened to me thats when i switched to the star pattern brake arm ,
Stevie Magana either the coaster brake needs to be cleaned and re greased or the inside of your brake surface is worn down to the point that it is fixing to break internally or lock up look for scoring on the inside surfaces , metal shavings , or old nasty grease , it could also be that your brake arm has been wallowed out and can spin on the shaft if that happens the nut will over tighten when you brake and cause severe damage often busting the rear hub in half
99% of sellers refer to the motors as an 80cc so most people looking for tips will search for 80cc motor tips not 66 no one knows more about these engines than i do if you are trying to be a know it all you will have to do better than that
yes you can , a coaster brake is optional you can replace the coaster brake wheel with a standard wheel or one from a mountain bike and just use a brake pad setup , i use both on my bike myself you never know when one will fail it is always good to have a backup
Posted 12 years ago and still helping people! I wouldn't have got my hub back together without this video! Thanks for this man you rock! 😀

you dont need to throw out your dust cap. You can dremel out the opening in the sprocket to be large enough to go over the dust cap and save your bearings.
is it bad to attach the coaster brake arm to the top bar instead of the bottom? I found it is out of the way a bit more
That helps a lot. How long do the bearings last?
I clean my bearings every hundred miles or so and repack them with grease , ive never had a bearing fail

dosent the coaster brake interfear with the motor? mine is a tomos a35 and must be back pedaled to start but it is mounted in a CFL schwin chpper bike
Hi am putting my bike together. Am having trouble when using back brake, the motor chain is still turning the sprocket and back brake kicks back. Any help much apprieciated.
What does it mean when u try to brake and the engine makes the pedals turn despite you countering the forward motion
It usually means that the coaster brake arm is stripped out , the hole with the two flat sides has become completely rounded out
So the dust cover is not necessary!?
Great video thanks for taking the time to do this ,it helped me a bunch
So can I just take the coaster arm off completely?
And leave it off ? No that is the only way your brakes can operate and without it the first time you forget and pedal back your brake will overtighten and your axle will either break , threads will strip or it will spin in place damaging your entire hub and probably the rear of the frame , i had the coaster arm center strip out once and thats what happened .

On the rear sprocket what side is the best, teeth facing in or out toward the frame? I see yours is facing out?
sorry it took so long to get back to you this whole new comment system is junk i tried every day to answer my comments but the reply button didnt work
its working today for some reason
the direction of the sprocket realy depends of your bike if it looks like the teeth or chain will rub your tire or frame then you can turn the sprocket around to get some more clearance

what happens if you remove the coaster brake arm only,and put the wheel on and start ride n
the coaster brake hub needs the arm to function properly it might work normally unless you back peddle at all or the brake is somehow engaged due to centrifugal force , in that instance your peddles will be forced forward and your hub assembly may over tighten itself since the parts that were originally stationary can now spin with the torque of the brake causing self destruction of the hub , i had a brake arm strip out once and that is what happened to me thats when i switched to the star pattern brake arm ,
I want to remove the coaster brake and put just front brake pad setup
so using this method I dont need a cone wrench?
That is correct ,
@@TheRandomMechanic thank you really helped me out I'm up and riding now
Can I keep spinning my tire with out putting it on
My braking all the sudden got extremely sensitive and will squill really loudly. Any ideas?
Stevie Magana either the coaster brake needs to be cleaned and re greased or the inside of your brake surface is worn down to the point that it is fixing to break internally or lock up look for scoring on the inside surfaces , metal shavings , or old nasty grease , it could also be that your brake arm has been wallowed out and can spin on the shaft if that happens the nut will over tighten when you brake and cause severe damage often busting the rear hub in half
my coster break is slipping when peddling forward,,,what's up with that
it sounds like you may have a worn out hub or broken part , you should pull it apart and look for excessive wear ,
Crazy helpful
What tire do you recomend i use?
i normally use the diamond tread pattern Duro 26/2. 125 , holds up well and sticks to the road ,
I couldn't find a video that showed me how these freaking things work and what the hell i was doing wrong
no problem glad i could help
Thank you man
Thanks for the video needed that
in metric its a 66 everybody knows that
what does this have to do with coaster brake tips ?
why not change to seal bearings
99% of sellers refer to the motors as an 80cc so most people looking for tips will search for 80cc motor tips not 66
no one knows more about these engines than i do
if you are trying to be a know it all you will have to do better than that
good video
gahhh you saved my day!
All that breathing.......:
it was 110 degrees in the garage without the fan running , normal texas weather
can I ride with no coaster brake at all
yes you can , a coaster brake is optional you can replace the coaster brake wheel with a standard wheel or one from a mountain bike and just use a brake pad setup , i use both on my bike myself you never know when one will fail it is always good to have a backup
