Motorized Bike Coaster Brake Warning!

- Today we made a 40 mile round trip on the motorized Huffy Cranbrook.
On the return trip we found out what happens when you try to use a coaster brake at 30+mph!
Turns out this build is good on gas by the way. At the end of our 40 mile trip we still had at least 5 miles left in the tank, giving this build a 80+MPG rating :)

I was the guy that said sealed bearings where better. I forgot to tell you coaster breaks don’t hold up to super human speeds on the bike. I use mountain bike rims on my cruiser most all of them have sealed bearings and eliminates coaster breaks. My cranbrook is a five year daily rider except in snow. 20,000 + miles on fourstroke 49cc i broke three of those coaster break rims. There expensive, just go with mt bike rims and ignore the large gear cassette, i just run a tight chain on one gear. Way cheaper !
I was thinking about using a MTB rim….but their spokes are punny….and a CNC hub kills spokes’ even if you make a key….it rips the hub apart…then the spokes…it very annoying!
How about those “heavy duty” 12 gauge spoked rims from bike berry? Are they any good?
@@ebperformance8436 no you just had the wrong sized hub I run 3 of those rightnow on mtb rims. No damage,no key,no rubber,no jb weld. Just blue lock. Tite on a good hub with torque. On 55mph+ race bikes.
I have a coaster brake on mine and have had zero issues. I think people are having trouble because they're leanin' on that pedal with every fiber of their being, and, having gone through more than a few coaster brakes for that reason, learned you can't do that. Gradual braking is key, and it also helps to have front brake assist, at any speed. This is all based on my own experience...
Yup just tap it works fine
This is the best Sonic commercial ever
lol :P
Yea, good Sonic plug. I haven't had queso burger before. I'm sold. 😋
I re-laced my stock steel clincher wheels with disc hubs and welded the caliper mounts onto the fork and frame. Although my welding skills are mediocre, they've held up well and give me more than enough confidence to slow down and stop quickly enough.
Good to know that little tip on coaster brakes. We have one on my wife's 50 yr old Vista that I occasionally rip down the road on lol
coaster brakes work, just have to adjust once in awhile. Make sure lock nuts are tight on cone nuts!! they do not spin unless the lock nuts were not tight to begin with.
Good job keeping it upright.
Coaster brake failure can ruin your day. If that’s all you have run it just remember to periodically pedal even though you’re not with cadence of the bikes current speed pedaling slowly to keep that thing from building heat. Keyword pedal slowly and not too fast you may throw your chain off.
Those tower thingies are loading posts for Traction sand, in tough situations where the rails are wet, covered in leaves, etc... Both steam and diesel electric locomotives have air driven sanders that shoot sand in between the rail and the wheel to boost traction.
Having a front disc brake is a good idea.
I had this happen 2 times... do not trust coaster brakes at high speeds! I was going down a road at about 35mph when it locked up on me completely. I did not fall, thank god, but I ended up grinding my tires into oblivion. I did take the brake plates out, and slapped a disk brake on.
I don't use coster brakes on motorized bicycles. The first time I had the little screw vibrate loose holding down the break arm, the brake arms starts spinning a million miles an hour till the hub seizes up. Once was enough for me. I take the brake arms off and use a C break.
I saw this one TH-cam video where instead of a mirror. This guy had a little camera mounted on the back of his bike.
And he had a little screen mounted on his handlebars. I don't have the know-how but it was a pretty sweet setup.
Damn I miss riding these lil engines.its not the same as dirt bikes but I'll tell ya I get almost as much fun... enjoyment I should say
Well, i was planning on running a front v brake and a coaster brake, but that seems like a bad idea now. I think ill just buy a dual caliper set now
Is the only think you have to change out is the coaster breaks for the cranbrook to be semi reliable? Can you put them on the steel rims?
So far the only failure I have had on a Cranbrook is the coaster brake. More specifically the soft coaster brake arm striped out.
@@LAHover thanks. So I’m going to be a first time builder and planning on getting a cranbrook and zeda 80 firestorm. What should I replace right from the jump? Delete the coaster brakes for dual caliper / hand brakes? Will I have to adjust the crank arms? Do you know of any videos with a guide to this since so many people end up getting rid of the coaster brakes? I am a first time builder and new to this so I am scared to get the cranbrook and not know what to do with it to make it more safe. I posted in your discord as well
The 40:1 is slightly richer than 32:1 and back in my racing days, we would do that to change fuel mixture a half jet size. It's not much of a difference, but you can tell easily between 25:1 and 50:1.
Im not sure but if you grease the brake shoes inside the hub, it may help with that. I did the same thing to a cranbrook and it seemed to help
I did the same thing with my Cranbrook packed it with high temp grease and removed the brake plate.I have disc on the front n shoe brake on the back
Hey buddy! Love your vids. Have you ever thought of doing a cylinder swap for a 70cc minarelli ? Makes the bike do at least 50. Also the NGK B6HS is a great plug.
Amazing how some of those colonies looked like they may have been Aztek...See ya next vid.Please let us know if it was the inner hub that locked.
There was a really nice all chrome rectangle flat mirror i got for mine awhile back for ten bucks at J&P Cycles Motorcycle/Chopper company. Its very good quality to me and doesn't move unless it is bumped with a considerable amount of force.
I added a rear U brake and use the coaster as an (e) brake...hope that will be enough for a 80cc motor, can't wait to get this project going will update.
Yes the first time I mashed down the the coaster brakes going over 30 miles an hour, mine spun the pedal crank forward too. I remember as a kid, I was riding down Cemetery hill, this was the first time that happened to me too. I know why local kids called it Cemetery hill tool.
I have a nice set of mirrors I got from Amazon under $20.00.. Mictuning universal hawk - eye motorcycle convex rear view mirror. Thanks again for your help in the past.
I found this video because I heard that coaster brakes can malfunction going at high speeds, and I wanted to see if other people had experienced this. I like to ride downhill on my BMX bike, and hand brakes don't completely stop you at high speeds so I was thinking of getting a coaster brake. I will just stick with handbrakes. Thanks for this video.
Why not go disc brakes
@@Mi_vida_loco Well, I have an older model BMX bike, and I don't think it can take disc brakes.?
@@imagesinla8575 they make disc brake kits for all size wheel and hub I have disc brakes on my stock 1984 mongoose bmx bike
@@Mi_vida_loco So did you just go down to your local bike shop, and get it done? Or did you order the kit from somewhere? I'd sure appreciate a little more info.
@@Mi_vida_loco By the way, I have an early 80's Cook Bros. Racing.
Glad you didn't crash and burn hover. Very weird when it happened to me. Woke me up quick 😂
My coaster brake also failed while I was driving downhill.
Almost had an accident thanks to the Coaster Brake itself even though it failed I was saved by it because the Hub locked inside and the wheel don't spin anymore and that's why it stopped me downhill for being a destroyed but still brakes.
The rpm burned the mechanicals inside the hub, the high heat caused to dried all the lubes and destroyed my brake.
I'm only using a China Coaster Hub.
Only last 1 month on Motorized Bike.
I check/grease my coaster brake about once a month or so. Never had an issue so far
Your mix change is definitely the difference in your high rpm knock/ping.
Go back to your 32:1 and enjoy, the power gain is insignificant if your tuned for the mix right, which it is at your old mix.
As to filing the key, yeah it can be done, but be prepared to crack the case regular to reset it and lock it down, the vibes will not allow it to stay set long
I like those drum brake rims, if I was gonna be riding fast that's what I'd do
Coaster brakes need a really strong bracket or strap, or the bike will pedal YOU when it lets go!
Agreed!
Ive never had a bike with coaster breaks very long, that bike setup is slick as hell though!
I did it's cool because you only need front brake lever on your right but have a lot of cons.
I think the coaster hub can't handle high rpm bevause it burns inside and dried hub the lubes.
Hey have ya tried the mirrors that mount into the grip? I got those on both my bikes, and so far so good with decent viz too...
Yeah I just picked some up and put them on mirrors seem ok 👌
Same has happed to my coaster brake except my wheel locked up. I took it apart and packed it red grease seemed to to the trick. But I didn’t trust it after having to carry the bike back. so I no longer have a coaster. Went with sturmey archer hubs.
Which stumey hubs did you get
I would not grind down the key way because it seems like a weak point. More prone to breaking I think. Also I have the same problem with my yd100. It doesn’t run the smoothest as if it’s missing a fire every once in a while. It has to be our Cdi or strength of the magneto
Damn I haven't seen a sonic in so long
That machine sounds sweet.
Thanks!
Somebodt stole my bike last night. Real bummed about it. I had a bbr racing motor and every part of it was upgraded.
You should check sites like let-go and OfferUp and Craigslist that's the way I found my stolen bike... call the cops tell them where they can find it on the internet and the cops set up a sting! try it
@@tedshredhard23 i tried as well with my bike that was stolen. Unfortunately i didn't find find anything of Facebook Marketplace Offer Up or Craigslist... I didn't have a motor on it but i was riding it to work and was planning to slap a motor on it.
true it does make the mixture more volatile by reducing the oil
What kind of hand brakes do you get for a stock cranbrook? Would love a video on that since so many people get the Cranrbooks and only use the coaster brake.
Leverage on coaster brake outtorques cone nut torque. Need to be converted to freewheel
I went down the snake hill in washington highs uptown nyc. I held the coaster brake so fcking hard trying to stop luckily i met a green light at the bottom when i stopped they were sizzling like butter and smoking hot never worked again
I have never had trouble with the coaster brake on my cranbrook now i don't go the speeds most of you guys go because I think 20 mph is plenty fast for that kind of bicycle. However i've only went about 15,000 mi on mine so I don't know maybe it does make a difference when it gets older.
I meant to say, Looks like you were smokin down the road like shot through a gun on that thing.. Haha
I have always refused to build a motorized bike with a coaster break. It's not hard to disengage the break geto and put real breaks n a double pull lever
i plan to use a freewheel with a 5 speed cluster if i can find a 26" with a frame of that type
Just went out of stock. But look up the Huffy Lockland (mens). It's basically the same frame but with rim brakes and a shifter. Also the Kent Bayside. Similar good for 2 strokes.
The same thing happened to me twice.... almost killed me.... so I deleted the coaster brakes and converted it into a freewheel..... so now I use nothing but mag wheels
The coaster brake operates on a worm gear type thread and with the forward torsion of the motor the way that the coaster brake engages it climbs the worm gear causing the crank to abruptly lurch upward causing the rider to lose control... Just fyi
Beach cruisers make the perfect gas bike….but the damn coaster brakes sucks.
A rear beach cruiser spokes are heavy duty, and a CNC hub is perfect….but the back rim always comes loose and wobbles….I might find a way to make it a free will and put lever brakes on the damn thing.
I even rebuilt the damn thing….and back the coaster brake insert lever is shedded…I miss the last cruiser I sold, I ended up welding a plate on the rim itself, and used a MTB rim….You can also get a phat motto back rim…their $125 bucks but they are one of the best gas bike rims you can buy….and it has the ability to have disk brakes….You will see them on every phat motto 4 Stroke bike….it’s one hefty rim!
Yup that happened to me and I welded a mount for a disc brake
I think some people are accidentally riding the coaster brake while driving
I would have never thought of having a coaster brake hub on a trail bike how do you do quick pedal resets without a cassette or freewheel
It has a freewheel,but if u move your foot slightly more back,you engage the brake,the coaster brake is the worst
I also don’t recommend putting a fixie hub on your motorized bikes! too much of a party lol
I hope you're still doing good buddy
I've had the same issue with the coastal brake arm where has twisted in the arm and caused the pedal to jump forward on a huffy noe loso
I’m not too sure about coaster brakes because I’ve mainly worked on cable brakes but could it be that he was going so fast that he grounded down the brake?
The cone nut spun and striped out the cheap/thin the brake are. I got a stronger brake are to replace it with. Now I only use a coaster brake for slowing down, not for emergency stops.
Hello, what size motor do you have and what size rear drive sprocket? Looks like you were smokin down the road like shot through the a gun on that bike!.. Hehe
This is perfect 😊
I think if you have a motor on a bike you should have at least one disk brake, some much better stopping, that's what I have on my kent moutain bike with bike berry 100cc is front disk and rear rim brake
I m going try take coaster break arm off and just use my rear break I got that same problem
That's y most people stick with either good old c brakes or go to disk brakes my friend that can snap the axle at higher speeds I should know it happend to me I've also bent the axle from them just remember it's a final stop break like ok now I'm at a light and fully stopped its mad dangerous on hot top hopefully u just spun the axle loose
Im considering buying YD100 or YD80 personally i prefer YD100 because i will be using it for cruising ( about 30 miles a day ) can you tell me witch kit is more reliable. I want top speed around 35 mph. Which is better and why?
i always honk anyone and everyone if im in a hurry , just to let them know im coming , be safe.
You should try running a b4hs that's what I've used in all my motorized bikes and I have never once had an issue with fouling or anything.
What’s the weather like around where you live? Colder? Or usually more hot?
@@DudeWithALude97 well I live in Oregon on pretty much always raining and right around now its below freezing most of the day
I like your bike it's nice 👍👍
try a smaller jet. 4 stroking on top end is to rich.
I went with a mag wheel because of the losing problem.
I'm getting ready to install an engine on my bike. So far I've only got the sprocket on and I put the tire back on but my back tire does not spend very freely what the heck I've tried to redo it like 8 to 10 times now and it's still not spinning freely any suggestions
Yeah I wound up taking the customer break off my 2919 crown Burger just cuz of that reason
I HOPE your axles are on really tight
have you tried a smaller gap on the spark plug? the gap may be to big for the upper rpm...
I didn't know Bill Murray road motorized bicycles.
😂🤣💀☠️
I bet he has not touched them in years. But how crazy would it be to randomly see Bill cruzin down the block lol
@@LAHover Hahahah that would be funny but I doubt he actually does. I said this cause you kind of sound like Bill Murray. It was a joke as if you're Bill 🤣 I'm surprised you've never been told this before
Run klotz 2-stroke oil read about the several different kinds on eBay I'm serious and premium gas
The arm has to be mounted down fast or that will happen sounds like to me ?
It was under the chain stay. Cone nut eat right through the brake arm.
I see a lot of what you do but do you do a lot of questions and answer live
Cause it wasn't help me see you riding an you tell me what you did
hello, I can't find any trails that aren't filled with dirtbikes or I can legally ride at. do you know of any good trails in the Melbourne Florida area?
What state are you in? Looks like nice country
where dose thus guy live like in the middle of no where
Louisiana
What do you think the best cruising speed is for a bike build
Lock up back wheel to many times
Have you ever had problem in your bike that the top chain from the engine is hitting the sidewall of the tire once in a while?
Yes, on a stock sprocket you can flip it over so the chain has more clearance from the tire. It's also important to make sure the wheel is true.
What breaks do I have on the front
Bro no coastersssss. Chain pop no brakes. Hit brakes too hard too fast no wheel in best case. Worst case bend frame when it locks up. Or you know an er visit

Your comment: Redundant.
go to amazon and cdh power high performance three prong spark plugs there sevel ones the on amazon z4jc is one of the numbers i might have try different ones
Is 40 miles an hour a good cruising speed and what bike would that be good on
Dang good run though
I have the same mirror on my bike so I know what you mean
32:1 is a better ratio for that engine
Hey, I have a motorized bike and when I wanna turn it on . I pedal and everything but I release the clutch and accelerate and it brakes hardcore , it doesn't want to run at all . I'm not even able to ride it normal
Adjust your clutch
Let it be a lesson to everyone who don’t want to die do not put a motor on a bike with coaster breaks.had he been in Traffic he would have possibly died.
Okay so I have a beach cruiser and it has coaster brakes I guess that's the pedal brakes I'm not really sure but I'm wondering if that would be okay to have on the bike with a motor please somebody answer me back
Yes, but try to and some rim brakes if you can. Coasters can fail during emergency stops. Also make sure both cone nuts on the rear wheel are properly adjusted after installing the rear sprocket.
In my sport once you out of motor you forget to work out and you find yourself using the motor all the time I imagine it's the same thing with bicycles that's why I deleted the motor on all my vehicles
I read this 4 times... I have no idea what you are trying to say.
@@LAHover I think he is saying that once we use motors on our bicycles more and more, we are less likely to use the pedals on the bicycle which makes us dependent on our motors than reverting back to pedaling our bicycles when s.h.t.f.
@@alexanderwhite1020 ah ok thanks... Well if that is what he said than I call it "refusing to have fun because you live in fear"
what size is the cone nut for our bike
Are these bikes easy to build? I’ve watched this channel for a while and I want to build one
Yes it’s very easy to build.
@@NicksBikes putting the sprocket on is by far most difficult. But all u need is patients
Go for it, patients, and loc tite, and permatex liquid metal epoxy 5500psi will be needed, and a willing need to fiddle a bit
easy but may require a third hand
Upgrade from magneto 12 volt or Oz magneto
😆 u love them oz magneto
@@macmotorizedbike3834 that's right the race magneto
How fast
11:00 What did she say?
Is that a thumb throttle? If so where did u get it and how much was it?
Yup, but that one broke. the one I'm using now is an AIO unit.

don't for get the three prong spark plug
what is the part number? thanks
ram mount mirror, Punch that into amazon and it will take you to the type im useing ! I'm only using 1 on my Z.A. bike and it's a hand-me-down from my Suzuki DR650 dual sport. I must of had my fair share of ground interface moments ,and only needed to re-adjust not replace !
th-cam.com/video/FlCzIvDwSx8/w-d-xo.html shows it
the 40:1 would be my bad sorry
It was worth a shot :)
