Bike geeks who actually make solutions to their problems are amazing!

[@troypeterson6057]

This is so bizarre- I went to school with Mark. I’m more into bmx racing but all kinds of bike videos pop up in my feed. I was about five minutes into this video and was suddenly hit with the realization that this is the guy one class ahead of me that was always tooling around on a freestyle bike. I haven’t heard from or seen him in 30 years. What a bizarre world to come across him in a random video like this.

[@Brant_Moore]

It never ceases to amaze me how small the world can be!!!! Either that or there’s some super super way too deep stuff going on with Google knowing the history of both of your lives

[@TheOtherMAJ]

Troy! I didn't know you rode, I thought you were more into skating? Crazy world, I haven't been back home in ages...

[@troypeterson6057]

@@TheOtherMAJ started racing bmx three years ago, I love it! I’m so happy to see you are still riding - you’re a true lifer! Oh and that bike is incredible!

[@TheOtherMAJ]

@@troypeterson6057 Racing is crazy, but the closest I've gotten is the pump track!

[@TheOGBasement]

@@TheOtherMAJguys get together to make a video that would be amazing and so wholesome!!!

[@guillaumebarrette9040]

As a diy enthusiast that recently got back into bmx, this man is awe inspiring ! Thank you mark and Brant !

[@alleng332]

Necessity is the mother of all inventions. How bad do you need it or how bad do you want it. Super trick and inventive, mad props. 😎🤙🏼

[@TheOtherMAJ]

Great edit Brandt, was great talking shop with you too!

[@speedmeade1]

His bike is Def one of the best ever in bmx

Using all of our experience and knowledge as we grow older to improve the things we loved as kids and make them even more amazing. This is the future of how we will advance in all aspects as humans. Individual advancements for the improvement of all.

[@pirate_duck4985]

Oh Boy! This'll be a good'en!!! Can't believe you kept this a secret Mark!! Thank you for all these bike checks Brant. Get to nerd out big time & I don't think a bike can get much nerdier than Marks!!!

[@TheOtherMAJ]

I was secretly hoping he'd lose all the footage!

[@pirate_duck4985]

@@TheOtherMAJ Hahahaha! C'mon Man, your bike is a work of art! You've put so much work into it, you gotta show it off.

[@mcsharkypmusic9298]

Teach me!! I’ve done some cool builds. But this!! This is LEVELSSSS!! 😮👌👌😀

[@dantoth3199]

Ive been into bikes and worked in shops for 35 years, this is impressive and very well done, congrats!! .. btw, the brakes are almost identical to a some vintage mountain bike stuff also the front hub looks like a Nuke Proof from bitd!!

[@dantoth3199]

Btw, what's the total weight of the bike, just curious?

[@TheOtherMAJ]

@@dantoth3199 Riding at 17.5 lbs, with full brakes and a 4130 frame

[@djta630]

I couldn’t wait to watch this video & it didn’t disappoint! Mark’s a great & talented dude. I feel fortunate to be able to ride with him every so often. Funny about the background noise - wasn’t a problem for me and I apologize interrupting your interview! 🤘🏽🤣

[@lovehate1982]

I am a flatlander and I met Mark last year in Colorado Springs in Battle In the rockies! He has so much good parts that he made that I was amazed! Too bad I don’t run brakes! But maybe next time! Thank you both for the interview

[@TheOtherMAJ]

Was great meeting you, your run at BITR was crazy!

[@thisisnotmyrealname9049]

Flatland with no brakes is wild!

[@siTTinLo]

Wow! What a talented dude. Incredibly smart. Sick bike too. 🤘

[@there_is_nothing_here]

Parasailing cord for the spokes is wild

[@nickepps1746]

This is so awesome on every level, very talented man.😊

[@MadelynHorecky]

love the S&M seat post but this mad scientist could make a carbon fiber seat post! would be sweet. The carbon brakes are sick too! tell him to make me some springfield carbons! haha cant be messing with those regular springs lol

[@joegaskill8742]

Dam! Incredible parts and attention to detail

[@GhostZero1111]

Incredible bike, my mind is blown.

[@tristancarver734]

I'd love to see all the modifications.

[@quoththeraven3985]

This Man is dangerous Thx guys.....mind blown!

[@philipparris4287]

Love this,the meaning of life!

[@nicholasbuttery511]

The sealed bearings in the U Brakes is interesting but i remember using ACS Boa Caliper Brakes that had open ball bearings that were hidden behind a rubber seal and a dial on nut and having to crack open sealed bearings in a vice to replace the bearings i had lost when they failed.

[@Wooder_Designs]

My favorite bike! 🙌 So stoked to see those barends on such an awesome bike 🖤🖤🙌

[@TheOtherMAJ]

Best bar ends I've ever had, still the first set and hasn't worn out yet. Might need you to print me some pegends!

[@briwelch07]

I love my purple carbon fiber brake!

[@mitchelltrollope94]

Very talented man

[@reggielavoie5048]

As a flat rider myself sometimes you need to make your own stuff to keep riding. Once had to use an unsealed axle in a sealed hub cause i couldnt find a replacment axle . Did it by theading a nut to act as a shoulder for the bearngs to seat against inside the hub shell on both sides and i never had a problem. Even recently had some frame mods to do to except 14mm axle on the rear because most flat bikes only made for 3/8ths.

[@G60syncro]

I'm not into BMX... more road and gravel cycling. I guess the algorythm pushed it a little when this appeared in my feed.... My day job though, is mechanical designer and my dad is a retired machinist with a shop full of tools and machines... I totally get this and csn confirm this is proper mad scientist wizardry right there!!!

[@910BMX]

This is insane!

[@brianstevenson5315]

The spokes are crazy

[@joereadel]

Always been a fan if Mark’s riding. Dude’s awesome. Great video, but maybe somewhere more quiet next time!

[@Brant_Moore]

Definitely gotta either go somewhere quiet next time or get a mic. Hopefully it was at least bearable!

[@souprememc]

I was looking for vids on custom painting rim brakes…this dude made his own lol

[@travisyork3915]

Sick build.

[@GolfSux]

I want a pair of those brakes.

[@tristancarver734]

I hope you get pattern pending on these because corporates might take it.

[@smokenal2]

The coloured carbon callipers he makes are amazing

[@HighVybeTribe]

that is a bad ass boy, I told you that

[@kingkong81icloud]

rope spokes 😮crazy

[@evotechcaeltd1583]

Amazing. It’s cool to see so much innovation - brakes, spokes, forks etc! Did you get the weight of the bike? I’ve been weening my flatland bike down to 26.5lbs (ground master with carbon rims, two brakes, 145mm cranks etc), but I’d imagine Mark’s bike would be a fair bit less?

[@TheOtherMAJ]

It's riding at about 17.5 lbs right now, with full brakes and gyro

[@FunnyAlligator-yy6te]

Sickness

[@tristancarver734]

How similar are your brakes compared to Dominik of Autum bikes, with bearings he's got? I think his calliper is alloy though l think.

[@offmynutzplz231]

I'm trying to find that brake saucer thing. Where can I buy it?

[@GhostYT_lat]

background noise unbearable...

[@DibeezyTheGifted]

Did he ever say what the total weight was?

[@Brant_Moore]

He replied to another comment here saying it's around 17.5 pounds. You can probably find the comment pretty easy if you wanna read his exact details.

[@DibeezyTheGifted]

@@Brant_Moore that's nutty. Bike is an absolute feather

[@DGass87]

What's the bike weigh?

[@user-tl4ki4oq2r]

Hard to hear the interview with all the background noise

[@MrFuchew]

I bet he's a mechanical engineer

[@eddieknight9234]

Should have we t with hydraulic brakes instead of cable pull....

[@brandonhoffman4712]

How much were custom made tires? $60,000? Oh wait those are store bought... Some parts are too expensive to custom make for a client. Unless Elon really wanted those tesla logos in the tire...
