THE TOP 3 MECHANICAL BMX BIKE MISTAKES!

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.

6:38 “spin it and look, it’s straight” the sprocket is bent lmao 😂

Lol

[@Khris_Man]

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.👍🏻

[@kyeflores2725]

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.

[@AlfredoMancuso]

[@DirtDigglerDetecting]

This is Genius. Thank you i didn't know a lot of this. Spokes and truing ?

[@soulgunner6455]

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" 👈||

[@renemadsen809]

I'm 6'4 and I ride a 21" frame with 13.5 backend + 10"bars and I think thats perfect for me

[@feeterican]

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.

[@cfmechanic]

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

[@kimoarmstrong3519]

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.

[@Catalan.17]

Hope you feel better Fredo

[@AlfredoMancuso]

Thanks so much Bryan

[@andreasheimann3310]

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

[@loganburdette6344]

Love these vids at epic keep doing them plz

[@user-zc9zt2vl5s]

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.

[@zemertv5950]

Thank you Alfredo sir for the video, so informative...👍👍👍

I sometimes need to replace the hatwasher because i crank so hard that i force the splines of my axle in de washer

[@KD-wy2cc]

lots of knowledge

[@williamgrissom1995]

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. 😎👍

[@kristianacearasula3085]

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

[@kerrboturbo]

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

[@blvck______]

Bro comment that in a newer video maybe he’s seeing it faster

[@tjbmx6440]

With my first bike, I had the hat washer issue. As soon as my part came in the mail. This video came out. 😂😂

Steering tube heightener on a BMX, good or bad idea ?

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

You’ll have to come straight to the shop one day

[@TKirkMedia]

id love to see anything design process related.

[@THEBEANLORD4]

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

[@Short_knowledge]

Next vid idea: chains, best ones for, not stretching, most durable, weight?

[@ogasthmaattack4145]

can you make a video about building up wheels?

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

[@logangarbiso3547]

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

That's a good idea because he could include the heat treating part into that video..

[@benbudd1376]

@@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..

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.

[@bmxscape]

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.
