Why Single-speed Mountain Bikes are Crazy Fun - Build & Ride

Today, we take my tired old hardtail mountain bike and turn it into a unique and fun shredding machine! Step one, switch out the 140mm suspension fork for a 150mm, and then take off all the gears. Yep, this video is for all of you single speeders out there. I've been to the dark side before, and I ain't going back. This bike is staying as a single speed for skatepark, street riding, trail shredding, and hiking—'cause this thing can't climb worth a sh*t!!!

For those of you asking, my gear ratio is 32/16. This is no good for climbing, but I need it for sprinting. With a single speed you need to choose and commit!

Is it a dirt jumper? Err not exactly. A DJ would have 26” wheels, slightly different geometry, slotted dropouts, and a shorter, stiffer fork. To me, this is more versatile than a DJ—and with all the great parts!

You perfectly encapsulated the single speed mentality: "I don't care. It's fun."

[souljaboi]

“You don’t have to worry about being in the right gear, because your NEVER in the right gear!” As a person who uses two primary bikes, one being a single speed, it’s SO true!

Seth breaks handlebar that’s more expensive than my bike: “bummer”

This is one of your best videos EVER! 🤘 That shot of you climbing up the last part of the mountain had me 😂😂😂

If you ride a single speed in the forest and no one is around to see it is it still cool?

This video really shows how freakin skilled you are dude. Unreal haha

I think we got a new bike name. Seth's Murder Machine seems acceptable right?

[magmachicken]

Dude you're like in your 40's and you're killing it at the park, i thought i was too old to do any of that! That's inspiring

[kevinhall]

At 53 years old, I ride singlespeed almost exclusively...and with a team of 20 guys who also ride and race singlespeed exclusively. Bring that Murder Machine down to Atlanta and ride with us!

I always said this three speeds to a single speed bike.

1. Sitting down
2. Standing up
3. Walking

The Murder Machine can legitimately murder you while going up hill.

I just love when Seth pulls his old bmx tricks on his new mtb's.

"It makes you feel like a kid again." That's why. Good job. Nice build.

The whole time watching this I could think about was my first single speed when I was a kid. I still have it and it might just be a big enough frame to build. Hard getting into the hobby again during a lockdown but you're channel has been guiding me through my journey again! Thank you so much and keep posting videos there great!

Single Speed! The way of The Single Speed is this; We are bikes that ride it all, not the fastest or most aggresive but we will teach you flow by showing you new lines on old trails. Endurance will come from varied cadence. Suspension will be found in you, as some sort of levitation holds your core as you relax your grip on the bars and dance on the pedals, hopping and spinning to the sheet music of the trail textures.

Awesome vid dude! Glad to see a return of the sync'r pro

[josiahhorning]

I watched this video the minute it came out four years ago, had to come back! I now have recently built my own single speed as well it’s so fun

What was the cheat code for the speed boost? 🚴💨
