- We used a speed gun to see what speed I am actually going before hitting jumps and features. This is kind of interesting, since it's hard to get a frame of reference with the tunnel vision you get while riding.

Not going to lie. I was always skeptical of an older friend of mine saying he was doing 40+mph down the trails around Bent Creek.
It would be really funny to ask people what they think their speed is, and then whip out a radar gun
@@BermPeakExpresshaha yes
@@BermPeakExpress next video idea
I remember my early 20's when there was an officer running radar in our neighborhood...I had my Robinson BMX 20" and was asking if he could tell me how fast I was. With a 44/16 gear and 175mm cranks and a 145lb body with a 30 inch inseam... 34. Speed limit was 25. I thanked him for letting me see...he didn't wanna give me a ticket and be ridiculed in court for pulling over a kid on a bike.
Fastest I've ever been on a road bike was 54mph also around same time period on a Specialized Allez 54 cm. Down a very steep short hill where it was hard to keep up with pedaling...
So yeah.. on a dirt trail with less ability to just mash the pedals and not die with rocks/roots/wildlife etc.... I'd also be skeptical...
Trying to get my funds right so I can put some bikes back together...
I'm 51 now and still have that kid in me that wants to ride bikes and jump stuff. I just never got beyond the no handers and my feet were never wanting to leave the pedals...still love riding. I am no R Williams with those bike flips! Crazy stuff to watch!
According to my Garmin watch, so who knows if it was correct, the fastest speed I've ever achieved was 39mph. Not on a trail but a very steep dirt road in the mountain neighborhood I use to live in. Very straight and very long. Needless to say, my butt was puckered the whole time. On a trail, the fastest my watch recorded me was 25mph. Again, very long steep straight section of trail. I don't do that much anymore...but I'd like to. Going up the trail? I'm thinking if I achieved 5mph it would be a milestone.
Those metric conversions wen't out the window pretty soon. Seth making me do math in my head while watching his videos... 😄
Yeah, thumbing down for that.
I just multiply mph by 2 and divide feet by 3.
@@Mike-oz4cv mph to km/h is about 1,6, so multiplying by 1,5 is way closer than 2.
@@megatryn better leave a comment like this, since downvoting doesn’t show up anymore, just influences the algorithm for you mostly, and only a bit for others
@@tbread1128 It doesn't matter. The algorithm counts it as interaction anyway. Thumbs up or down don't matter.
The great thing is that you don’t need to have a degree in physics to MTB. Seth you inspired me to start my own channel and record MTB footage. Keep up the good work!
the bad side of the equation is that a physics degree won't make you a good MTBer either.
Even worse, it won’t even make you good at physics.
@@ff00005 you don't need to have a degree in physics, nor be an MTBer, to be do a lot of things in life. So there's that 😂
Same! It’s exactly why I made my channel
I agree 💯 that going 24mph feels like 500 mph!
805 km/h!
I road bike and 24 on a flat open road is not slow - can't imagine in the woods.
I'm in the mid 30s on some downhill sections on my mountian bike, its sketchy but fun. And yes I track my speeds
@@sapperROSS that's gotta be absolutely terrifying
@@theGiver3 haha depends on the trail.
Thanks for the promised km/h conversion on screen THAT ONE SINGLE TIME YOU ACTUALLY DID IT!
Great job, Seth. It’s always fun watching your videos. You have inspired me to build my own Berm Peak in my backyard, and keep up the great work!!
Thanks so much for providing the metric information too😁
Banana: 18 mph = 29 km/h
Double: 17 ft = 5,2 m, 18 mph = 29 km/h
Snake pit skinny gap: 7 ft = 2,1 m, 14 mph = 22,5 km/h
Rock garden: 20 mph = 32 km/h, 24 mph = 38,5 km/h
Doing Seth's job for him
Where is oscar?
thank you
Why is it an American's job to translate our system of measurement for you to understand? I mean there's plenty of better ways to seek attention then to wine about someone not calculating things for you.
@@silvajay6443he converted the fastball. But couldn’t convert the other shit? Lazy af
@@silvajay6443 because he set it up in the start of the video and didn’t follow through.
Also imperial measurements are stupid to begin with, get up to date americans!
Best MTB videos! Keep it up Seth!
Since getting into ebikes, I have a speedometer on my bars. I'm not often able to look away from the trail at speed, but your speeds are pretty close to mine. Except a-line, where you add 8mph to clear the big jumps 😄
That was my first thought...how fast was something like A line? Thanks for answering.
Love the vids seth!
Thank you for making this video. it's a big question I've had for so many years. I now understand how speed works when it comes to jumps.
Big thanks for putting the conversions❤️❤️
Excellent vid, thank you!
love your videos Seth !
Very good video. Really like the way you explain things. Keep up
Never have I ever seen anyone with this content and bring up a speed gun to make a point. Kudos
Love you work! Binge wt hung while work on my bikes in the garage… thanks!
That story about what people think mtb is, reminds me of when I started taking my son with me on trails with a trail a bike. He was maybe 4. When told non riders that I took him with me they lost the color in their face and had a far off stair like I had just pimp slapped them. I know they must have had every old Mountain Dew add or whatever going through their minds, that’s on them. Same continues as he got older. What people don’t realize is that this is all learnable, individual skills. When he first started to ride on his own bike, he walked a lot. But we kept on the same trail loop for years, he kept getting braver, and I’d praise him for riding through something he had been walking through for years. He is 12 now, and we start every ride with a new skill, we run drills till he is ready to ride and he chooses to use or not use what he has learned. Sometimes it’s weeks later when he does use it, sometimes instinctively. Teaching kiddos and having them light up when they get the technique mid trail, is one of the best things ever.
So cool. Good video of you going fast. Looks fun. 😁
Great video! However, the uneven helmet visor is killing my soul😂
I think it’d be kind of interesting if you made a video all about filming techniques you use! Like different GoPro mountings, settings, different angles, filming the same shot from different locations, etc.
Be interesting if you had a racer and a freestyler hitting the same jump just to see the difference between speed and pull up power!
Thank you for the mph to km/h conversion
For the rock . What matters did not get a conversion.
That's exactly what i needed
Love your videos keep yhem up
How my friends imagine mountain biking, is
riding in a gravel path.
Glad people see me hurling myself off a lip aimlessly as me being a super smart physicist
YES NEW VIDEO
Very cool content 🤘🔥
What I learned is to hone my intuition. Thanks Seth!
Great test !
Thank you for including the metric System!
Hey Seth I've been with you since the very beginning. I remember when u were Seth's bike hacks and you had been creek. It's so cool to see how much you've grown as a TH-camr. Keep up the good work
I was there before the beginning.
I was here before you were born you look 10 years old
I was there before both of you put together!
Congratulations. Do you want a cookie for your achievement?
@@theGiver3 yeah sure
the friction-less plane reference got me ;)
Omg I love this, teacher Seth in the HOUSEEEE
Great vid
Seth's Visor @0:23... My POC visor is ALWAYS crooked. THX for keeping it real, Seth!
That awesome Industry Nine Hub🤩
"I'll put up some conversions" proceeds to not put up any conversions lol
This Is really creative
Its the best thing of the week when Seth posts a video
I think the most valuable part of this for me was watching you jump. I'm still figuring it out and just seeing you do it over and over - full speed, no slow-mo - was really interesting.
Great idea! I'll share this with my friends jumping on Electric Unicycles and ask if their speeds are comparable.
This is an interesting video, and I like how you put in the conversions in the intro. However, right at the first jump and every jump after that, you forgot to put them on the screen for us non-imperialists. :D
great new vid!
Funny subject. Reminds me that Douglas Adams referred to "playing catch" as "performing amazing feats of differential calculus".
Awesome content as usual, Seth. I think it would be cool to compare someone else's speed across the same features in another video.
Yay new vid
Wish I had a big that was that smooth over the rock gardens.
I learned I will watch absolutely anything
Very interesting my g
Thank you for straightening the visor
Seth it would be great if you could do more crawler videos I love them
Hi Seth,
I just ran some calculations:
On the Banana Cannon, the theoretical speed (assumption of ideal conditions) required to clear the 17ft (5.18 metres) gap would be 24.1 mph (38.79 km/h), which is 7.1 mph (11.43 km/h) off of the measured 17mph (27.36 km/h) and 10.1 mph (16.25 km/h) off of your prediction of 14 mph (22.53 km/h). The accuracy error of this calculation is therefore 41.74%.
On the double after the Banana Cannon, the theoretical speed would be 16.07 mph (25.86 km/h), which is only 0.93 mph (1.5 kilometres per hour) off of your prediction of 18mph - the error would only be 5.5%.
In theory you should have gone at least 3.3 ft (1.01 metres) into the air.
In order to clear the snake pit gap of 7 ft (2.13 metres), in theory you would need a velocity of 11.7 mph (18.83 km/h), 1.3 mph (2.09 km/h) less than the measured speed of 13 mph - error rate 10%.
On average, your guesses were on average 88.24 % accurate.
Does this include preloading and the 'pop' when you jump?
@@zmfb No these calculations only account for a passive jump, so basically just rolling over the lip in order to get air.
More advanced physical models of jumps incorporate complex systems of differential equations, for which I am probably underqualified.
However, due to the difference between the measured and the theoretical velocity, it can clearly be seen that preloading the suspension and the rider actually performing jumping motion lowers the required speed by quite a bit.
That visor has seen better days.... LOL
Love this video Seth. I've been watching the channel for years now and have never owned a mountain bike or been on one since I was a kid. Just love your creativity and genuineness. You're the best.
Yoo seth love from 🇦🇺
Haha the classic bent visor on your helmet 😂
At first I was really happy as a non American for the conversions but then... they went out the window hahaha better luck next time, I guess that I got some homework for tonight. good video still
I learned something but then I forgot because you told me to forget, I think? 😕🤷♂
Great video!
friends that dont understand mtb always make you feel like such a badass.
That is interesting. I'm curious now how other riders with similar or different styles hit the same jumps. You should record Alex and your other friends riding with you and see how different riders tackle the subject of speed over those same jumps.
Very cool
That bent visor is sending me.
This helps a lot since we use km here and I don't know how to jump. Might as well get a data
I'd like a same style vid on control while jumping. How to not loop or dive or freeze up in terror. All I've heard is heels down, stand tall, etc. Is a trampoline the only way to learn air control ?
Seth is one of the most entertaining mtb youtubers
Seth is definitely THE most entertaining MTB TH-camr. Bet he is top 3 of ALL TH-camrs
4:34 got a Doug Demuro "This" going on for sure!
Entertaining yes
Love it, thank you that you do Meter and KMH for the European love it!
Once....only once...
@@Jan-Cort true but he tried
Well done video! More unit conversion to metric would have been nice though. I guess a large part of a flowy feeling comes from the ideal speed of a trail being somewhat constant.
Thank you for the kph and meter conversions for us Who dont know anything about miles and those things😁
I don't know how accurate they are but you can try those magnet things that tell the speed on bicycles
I have a physics degree among others. There's lots of fun things you can calculate. The trajectory off of the airbag jump would be fun to analyze. Distance, height, and airtime would fun to calculate
Gotta unlearn what i learned now, however i did find it entertaining!
I use the local 'your speed is...' traps on the roads. They're probably no more accurate than an Amazon special radar gun, but it's handy to gauge how much push in which gear results in what speed.
Also, my phone freaks out when GPS signal drops, and I've seen 2,550mph indicated. If only! Pretty sure I could clear anything at over Mach 3.
Does anyone else want Seth to do some brainstorming and episodes with smartereveryday?
What are your thoughts on belt drives? You should do a video reviewing them!
Hey, Man. Nice vídeo. Let me ask you: I simply love trail and I really would love to jump like you guys (I mean, whoever is able to do those jumps) but I confess the will is there but the akills are not. Specifically, how do you do? Doesn't matter if it isnthe double or the banana...do I have to yank up the front of my bike or simply passe through the jump? Do I need to move my body back (like trying to "hold up the horses")?
fun fact if you press the button on the radar gun once and hold it down for 3 seconds and let go it’ll switch to kph I think. Love you Seth 👍
Better than looking up the MTB launch angle web calculations out there going into Parabolic Jump/Projectile Trajectories.
How u liking your Mous case?
Would be cool to see some measurements from berm park
The helmet shield in the beginning.... Saving James Ryan? 😆
Can you do a review on the canyon neuron cf?
You should do another video with the speed reader but you go through all of your bikes, even your wacky ones, and figure out whick one can keep more speed through different corners, or if its a carbon bike, how much that affects your speed out of a corner or jump.
I have speedometer mounted handlebar from cateye and when I was editing footage from thunder bike park, black jump trail and I was able to see the speed around 25mph at takeoff. So I guess my speedometer is pretty accurate.
Waiting for the next bikeflip video
Interesting. What radar gun did you use and how much does it cost?
I wanna see this on emtb now, to see if speed is different
Hey seth i was curious, could you run the entirety of berm peak without pedaling and just letting a trail dictate your speed
do you think you went faster in some points for the radar gun?
good to know i have to be going the crusing speed i sit at while im on my road bike to hit a jump
The rock garden feels like you're going faster than you are for the same reason you feel like you're running fast in a hallway.
would be interesting to compare your speed using your different bike, carbon hardtail, TI hardtail vs full suspension
I think any hardtail would be about the same because 1 or 2 lbs isnt going to make a huge difference compared to your bodyweight but full sus would be faster
So, we did learn something today, the speed we need to clear jumps when we got invited to berm peak! lol
wow thanks so much for converting like you said you would...
Can I recommend trying going to your limits of how slow you can still boost over the jumps and how fast you can get goin over the gaps. Just wholesome scientific fun.
cheers and great stuff as always
So funny to see your helmets visor twisted, jajaja
