- As some of you guys know, your boy is struggling with Kidney Stones, so keep me in your thoughts. But today's video was filmed yesterday, before my first run in with the issue. Thanks as always for the Vu's, willingness to help me with the weekly content! In today's video Phu Vu (@_epicbmx) goes over the Top 3 Mechanical mistakes on your bmx bike! The first is the sprocket hat, chainwheel reducer or adapter, which is what causes issues with loose chains or tight spots in your sprocket. The second is the lack of spacers in your headset which lead to a loose headset, ovalizing your headtube, and crushing your headset. The last is adding a race, to forks with built in races.

Man if a shop like this was in my city id go every friday!
6:38 “spin it and look, it’s straight” the sprocket is bent lmao 😂
Lol
i just put my bike together weaks ago nd i made very simple mistakes so it took me longer to put it together. it was my first time doing it next time i won't be making the same mistakes.👍🏻
I’m more into mountain bikes but I have a 12y/o who lives and breathes BMX. I’m completely out of my element when doing any repairs/upgrades. These videos are hugely helpful, so I appreciate the time that goes into making them. As a suggestion, a video about cheap parts vs expensive parts. Thanks again.
Thanks Kye! Give this video a watch :) ua-cam.com/video/x_qZREXQNjw/v-deo.html
Keep riding , he can't keep up with you on a geared bike.
I've had that problem with my chains so many times and never knew that was the problem thank you
Stoked we could help :)
Phu, you are awesome !! Thank you for sharing these great insights ... seems simple, but only experience can give you the best results.
Great vid man ... I can watch this dude all day !
Great vid Alf and some great advice From Phu
Thanks my dude
This is one good channel,subbed here in australia🤙🏼
Thank you Alfredo sir for the video, so informative...👍👍👍
Very educational, thanks!
Everyday you learn something. And it is cool. I loved it. Thanks.👊
Master Fu at work :D . I like the no BS style. Too many safe space cupcakes these days. Fu is keepin it real :D
Hahah he really does
Im old school so all this stuff is second nature to me so i just watch for the entertainment!
So old school i still build my bikes upside down on the floor 😝
Lmao same.
@@dantegerard70 Wait! The youth don't do that this day in age. Tisk tisk on the youngbucks.
@@randydube1423 I do that
this dude is a gem great content for the channel
Love these vids at epic keep doing them plz
I just built my first bike in ten years and this video helped me figure out my sprocket problem thank you
Glad we could be of help :)
These are so helpful
I needed this and i didnt even know it. Thanks Epic
Phu da man!
Hope you feel better Alfredo thanks for getting this vid out
Love the tech stuff. I'm from the late 70s,80s Era and this is new to me. But I love some of the upgrades that's been made since then. Threadless forks and stem system is one of them that I really like.
I really like the sealed bearings in the hubs and bottom bracket. Though I'm not sure what have with sealed bearings in my current (customized from previous owner) bike from the early 2000s a Kink Freebird. I will want to change to sealed bearings whatever is not sealed, eventually.
Subscribed. 😎👍
These are some of the most detailed and easy to understand videos ever! Thank you so much for doing this. A bike shop that's upfront and knows exactly what they're doing. With that being said, I would love to see a video on how to properly install cranks. Because I have run into a problem where I rotate the cranks with my arm but they seem a bit tight and don't rotate freely. If I loosen one of the crank bolts then it fixes the problem but then the crank bolt is loose. How to fix this problem so that the cranks can spin/rotate freely with the crank bolts secure and tight? Also noticed that when I pedal hard that I sometimes here this clicking/pop noise from my chain. Not sure if its related to the issue I mentioned or if it's something entirely different.
More of this guy !!!!
Phu the BMX scientist
✌🏾 Bro.... glad to see the contnt up, hope you feeling better bro ✌🏾...
Informative vid as expected. Hope Alf is ok now.
Heat Treating, hell yeah, pre, post, etc. Riding / geometry too, yes please !
Master mechanic. Experience comes with the work and time on the job.
lots of knowledge
Epic!
Much love Alf 🦾
💜🙏🏻
Good vid
Phu teaches things in a manner my mind easily understands... Thanks Alf and Phu
Best tumbnail ever
Nice shorts!
Thanks man I was wondering if anyone still used that bottom spacer on forks anymore because they don't seem to fit real good so I don't use em also your wheel truing video helped me a lot
this is good knowledge....
Would love some tips on geometry for tall riders 6foot and above.
I'm 6'4 and I ride a 21" frame with 13.5 backend + 10"bars and I think thats perfect for me
I'd really love to see a detailed episode on bottom bracket on installs. Especially involving the spacers. I have a bike where my bearings won't seat all the way in because the long spacer is a little too wide. I hope this isn't a problem.
Niceee. Good info! Can you guys do a brake comparison?
Tbh I had no idea why the chain loose or tight even the head set part very helpful
Glad it helped! :)
This is Genius. Thank you i didn't know a lot of this. Spokes and truing ?
Flip the bike on its bars and seat, bike stands better, Zip ties on fork and or chain stay of the frame if its rear wheel or use your front or rear brake pads and calibers to help with a zip tie on the brake lever in place, when you got 1/4" distance from brake pad to rim... start counting spokes from where the bend starts to end, if its bent from the left then loosen those spokes about 1/4" then tighten the 2 opposite sides from the 1 spoke you just loosened the same exact amount a 1/4" tight.
Mini Diagram: loosened Left Spoke Nipple to 1/4" 👈||
Hope you feel better Fredo
Thanks so much Bryan
With my first bike, I had the hat washer issue. As soon as my part came in the mail. This video came out. 😂😂
Thanks alf for going to epic. I'm stuck ag home under quarantine some of my family tested positive for covid. This vid made my day. Tell phu maybe some tech stuff on brake pads I know there's a wide selection
Damn, I’ll keep your family in my thoughts! Glad I could help send a little bit of vibes
I keep cracking up when he’s saying all types of shit then is like “well guess what, you did it wrong”
id love to see anything design process related.
5:53 When i replace a chainring i bolt it to the crank arm 1st then put the hat washer in then put on the cranks 👍
I literally was just able to fix my chain because it had the same problem. Thanks for the helpful tips!
Phu said 5 mm below the stem, the recommended should be about 2mm. Good info though Phu helping a lot of these BMX jack mechanics out seen too many stripped stem bolts and top caps haha
My friend gage stripped a fork cap from a 6mil to a 10 and the 10 is stuck in there
Can you do a video about rear V brakes? They seem easy but I seem to have trouble adjusting them...
Bill is actually a mechanical engineer and has done some cool ork even before the tv show... I bet it would be interesting to ask him about torque and velocity... haha 100% "whazzap players" gif
#1 the reason why i run a splinedrive system
Can you do a used bmx buying like things to look for vid? Ive been screwed on some secondhand purchases over the years just because i didnt know what issues to look for
Bro comment that in a newer video maybe he’s seeing it faster
I want to see Max Vu The Science Guy
Haha that would be a hilarious episode
I sometimes need to replace the hatwasher because i crank so hard that i force the splines of my axle in de washer
I was a bike mechanic for years in the mid 90's (I was changing my flats when I was 8yo, small annoying flex (I also ended up having to fix all my friends flats too, even after showing them how)) and the the new subtleties to how a bike is build is going in the right direction. I challenge you to find a 3 speed from the 50's and disassembly completely, 3 speed and all and show the viewers how far we come. Just the jump from the mid 90's to now has been a game changer.
Next vid idea: chains, best ones for, not stretching, most durable, weight?
Pooh knows BmX bikes.
I still regret not going up to fu at the house park jam couple years ago but I shook Max’s hand
You’ll have to come straight to the shop one day
that washer is what i need for my bike ive been using my bike without that hat washer and my chain keeps on making sound i cant afford to buy one of those washers because in our country you can just buy the washer alone its rare its either you buy it with the whole crank set and i dont have the budget for it lol
Ya know people would pay good money for phu’s knowledge
A tip also if your bike has chain tensioners clean dirt and grime out and regrease every couple of days stripped tensioners are not fun to deal with
My tire always rubs and shifts against my frame after riding how can i avoid this? I don’t have chain tensions built in to my frame will they help?
ok i need to check my bike now.
Hahaha if you’re missing one of these things I’m gonna be disappointed
@@AlfredoMancuso No, not missing. LOL #LunzBMX my other youtube channel has some cool skate park stuff i did. Old ass jumping up the stepup and dropping in vert. LOL GOood times
@@AlfredoMancuso I can't stop thinking about the skate park. I just want to ride..... So adddicting. Dirt Diggler :)
Wow I could’ve saved so much sprockets I just thought it was bent so I god new ones well I guess I can say support bmx shops
facts
I want to know about cassette hubs and points of engagement, pawls, spings ect.

quit bmx about three years back but i still watch ya videos bro keep it up 🙏🏼🖤
Appreciate that, but you should get back on the bike :)
Alf i want you to get better bro❤
Even if people didn’t know what was wrong with the headset. They would of watched it and then commented and been like, gimme free product- na man ahah
can you make a video about building up wheels?
He already did, not too long ago
I purchased a 1 1/8 front Forks but the Bolt that came with the headset I purchased it's the wrong size it's too small are there different size bolt for 1 1/8 threaded Forks
Make a video about building a wheel!
The difference between a star nut and a expanding nut bolt on threadless steering tubes. Which is better and why ?
What?
Steering tube heightener on a BMX, good or bad idea ?
solución argentina al problema... poner esa pista de rulemanes de spacer... .... es lo mismo poner la arandela de la corona de un lado o del otro? o sea que el lado "ancho" quede del lado de la palanca o de la caja?
Can I take my 24 inch and converted into a 20in if I have a 20 inch frame??
0:40 i first saw that on seths bike hacks channel
What about cranks with spline drive sprockets?
😎✝️
First
Lukassss
How much are repairs. Also would you be able to set up a phone line so were able to call your shop.
714-848-0888 repairs start at $20
Thx
More spacers please
Is it ok if my spacer is loose,but my stem is tight and can still ride my bike?
Those stamped steel sprockets all do that after a while .
True
So what happens If you loosen up the compression bolt before the pinch bolt ?
Talk about brake bosses and how to install brakes
0:53 I have a minor version of that. It isnt as bad as this, but I have the tight /loose /tight/ loose going on. I have checked everything mentioned.
chains dont stretch evenly and even sprockets arent always perfectly round so to have a little bit of tight/loose is normal. if its not way too tight in the tight spot and not slapping your frame in the loose spot you are good.
@@bmxscape Thank you so much. Yes, Im just going to let it be.
Because it is a compression cap then you tighten those and if you tighten it too much then it won’t move but if you time it too little or move
My local bike shop hates BMX with a passion, I was getting my wheel trued & The guy working on it Says I don’t know how to tell you but you broke your axle so I am stressing at this point then I had to explain how female axles worked so they charge me $70 to trim my wheels so yeah fuck that place. I’d kill for a local bike shop that supports BMX
They charged you $70 to true your wheels?!? Dude! 48 Brand new spokes are $25 and labor, at the very most is $45 so for $70 they should’ve replaced everything on that wheel!
Whats a good bmx bike to buy for $300?
16:48 it will be cool!
What is the name of the song playing in background?
Different stems top loads and front loads and other more stens
An old bike shop fella used to describe our junky lookin bikes as well boiled iceicles when i ask what he was on about he replied its the other end of the scale of a well oiled bicycle lol he was calling our bikes crap in a freindy old man way lol .
should there be a washer on the hat washer with a washer behind it
Do a 4130 chromoly Vs Hi-Ten steel video for those beginner bmx riders so they don’t buy the wrong bike
Can you please do a video on how to centre a 2.4 tyre with rear brakes....clearance is tight and sometimes tyres are not 100% even with that 1-2mm play
That's a good idea because he could include the heat treating part into that video..
@@konfushez316 hey I use either a pair of pliers or even a piece of wood and I stick it in between the tire and the frame at the wishbone and if done right will center your wheel and then you can tighten your axle nuts..
7:59 If this happends you need headset spacers 👍
Different frame geo for different riding styles
