LI Trail Riders Roadtrip - BeastWheel Underground Racing 2023
I've been riding trails with this group for the last 3 years, and this past summer for the first time we took a roadtrip! We got an airBnB in NH, and planned a 3 day trip. We ended up getting completely rained out on day 1, so we had to squeeze everything into just two days. It was a jam-packed couple of days where we rode trail systems in NH, MA, and RI. The segments are from the Beastwheel Underground racing segment for 2023, and we had a blast exploring their trails. This video took a long time to put together, and it's my best attempt at capturing the fun and adventure of the trip for all of us to remember.

Escaping the cold! Sunny ride in FL - Inmotion V11 and P2F
Просмотров 9353 года назад
This is my favorite type of riding. Low key, relaxed exploring with my wife, somewhere we haven't been before. The best thing about the electric unicycle and electric bike is how far we can explore together. Without a car, you can stop and investigate anyplace that looks interesting along the way, and it's a completely different way to experience an area. Join us as we venture from Green Spring...

What would you say if I told you that all the 3D objects you see in HS Geometry fall into one of two categories? In this video I'll introduce you to the second category, which I call "pointy" objects. Many different shapes fall into this category, and your textbook has a different formula for the volume of each one- but if you understand how these shapes work you'll see that they all follow the...

i think you are mistaken with the last question, yes rounded off the answer is 5,7 but the ratio is tan not sine, the distance from the hot air balloon to the house is the horizontal length not the diagonal length.
Hi- thanks for watching and for the comment. This does sometimes trip students up at first, as they want to measure the distance along the ground. However, the distance from the hot air balloon to the house is the length of a line segment connecting those two points (the balloon and the house). If you were to draw that line on the picture it would go through the air, not along the ground. The distance you're thinking of (along the ground) is the distance from a point on the ground directly under the balloon to the house. Does that make sense?
Fun
❤❤
Love you man, even if it's 8 years ago, you saved me from dropping out.
Oh wow- so glad it helped you out. Thanks for letting me know 😀
thanks sir
You’re very welcome- glad you found it helpful 😀
My college professor doesn't explain well. Thank you so much for this video
You’re very welcome, glad to know it helped you out 😀
We watched this in math today while we worked
How fun 😀
Brother. Wicked. Looks like you and the wife had a fun day out. :)
Oh wow- this is an old video 🤣 Yeah, that was a really fun day 🤙
your intro is fire
Why thank you 😄
You're a good teacher
Thank you so much 😄

20:34 how did you get 64
I'm not sure what you mean, I don't see any questions with 64 as the answer.
Question. I have jump pads for my V11Y but what are power pads? Where do I get them for my wheel?
Best to ask in the Telegram group- my wheel's been setup for 3 years and I have no idea what's available now.
@@RealMikeDobbs ok
I was finally able to get telegram to work for me and I hooked up with a rider named “HOTT”. Thanks for letting me know about meeting other riders. Mark
Alright- glad to hear it man 👍
9:29 leaning tower of pisa
That's fair 🤣 I'm better at math than at drawing, but as I always tell my students: it doesn't matter if your picture is good, it only matters if it's useful.
I hear ya. It said that it would send me a code on my other device. I only have one iPhone, an iPod touch and my IPad Mini that’s at work. I gotta wake up 3:30am for work so maybe tomorrow is a better day? Later. Mark
The most beautiful and truthful lyrics 😮❤ Especially as someone who is afraid of factoring and quadratics😂 Btw your rapping is so great😊
Oh wow- thank you so much ❤️ Nothing to be afraid of by the way- it’s the same as anything else. Scary at first because we don’t know what we’re doing- but once you understand it’s no big deal- keep at it 😀
Every example is knowledge of the hypotenuse. What if you know nothing about the hypotenuse, but know the 2 legs - “A” & “B”? How do u solve for the altitude?
Thanks for watching. In that case, use Pythag to find the hypotenuse and then proceed as shown in the video. Remember, anytime you have two legs of a rt triangle you can always find the 3rd with Pythag 😄
How do I hook up with the group? I’m in Brentwood.
There's a telegram group called Island Ridez if you want to check it out. t.me/lirides
Tnx! I will check it out when I get out of work today. Is it mainly only V11 riders? I have the V11Y, V5F and mten3. Mark
@@EUC_Senior I don’t really ride with the group anymore (I mostly cruise around with my wife these days), but I’m still friendly with them. Probably mostly higher powered wheels than the V11, but they welcome all types of riders 😀
Cool! I will try to check out the group with the link that you sent me. Happy riding! Mark
Hey Mike, I was just looking up this telegraph program thing and it’s asking for my phone number then on the IOS App Store the app wants money per month. I’m getting red flags with this method. If you have telegraph up and running, can you just pass a message along to that group? Or think of something else?
Wow 😲
This is an unrelated question to a Blokart video you did years ago. Can you share how you made the connection from the kite buggy to the Blokart. I’m most interested in how you connected from the Blokart axle to the copper tubing yoke. Thanks
Oh, I was very proud of that idea actually 😄 It was a very simple connection, but did a great job. I took some braided rope and fastened it to the axle of the Blokart with a Clove Hitch. Then I took a short section of PVC (or maybe a coupler) and passed the rope through the PVC, around the copper yoke, back through the PVC, around the Blokart axle... repeat this 4 or 5 times until the rope fills the width of the PVC, then attach the loose end to the Blokart with another Clove Hitch. Fast to setup and take down, and the connection allowed for rotation and some lateral movement.
Thank you so much. It's helpful ❤
You’re very welcome- glad to know it helped you 😀
Thanks a lot. Amazing explanation.
Thank you so much! Glad you found it useful 😀
This video really helped me. My mom bought me a workbook, but it makes no sense.
That's terrific, I'm glad you found it helpful 😄
Very well presented. I'm doing this for kicks, and it's applicable to Celestial Navigation.
Thanks very much 😄 Sounds like an interesting application.
That's terrific, I'm glad it helped you. Thanks for letting me know 😄
BRO OMG YOU SAVED ME ‼️I have a test on this 😭 thank you
That's terrific- so glad it helped you 😄
Wow amazing video! I understood so well!
That's fantastic- thanks for letting me know 😄
Is this considered a real sport? 🤔
I suppose it depends who you ask- we certainly think so 😎
Using electric bikes defeat the whole purpose 🤔🤔
I guess that depends on your purpose. My purpose is to get outside, spend time in nature, have fun, make memories, and share it all with some great friends. We're checking all those boxes every time we go out 🤙 *It's also more physical than you might think- pretty similar to skiing or snowboarding; and we're developing our balance and proprioception.
What if you aren’t give your own vector, and you had to make your own shape?
Well, in order to construct a translation you need a vector to define the translation, so you would always be given a vector in a test situation. You can certainly create your own vector and shape for practice- but in a testing situation I would expect both to be provided to you.
For my class project we were given a black piece of paper and told to make our own “unique shape” and do all 4; tessellation, rotation, translation, and dilation.
Sounds like a good project 😄
good video
Thank you 😀
Tomorrow I have a math exam, and I was so stressed, but after watching your videos, I understood everything. All the love from Saudi Arabia
That’s terrific to hear, I’m so glad it helped you. Thanks for letting know 😀

Thank you I watch for Papua New Guinea and that really helps me .I am so grateful 🙏🙏🙌😁
Wow- so cool that people from all over the world can benefit from these. Glad to hear it helped you out- thanks for letting me know 😄
thank you for teaching me this, i was absent when my teacher teached this lesson and my friends are horrible at explaining things, i am definitely going to pass the finals
That’s terrific- thanks for letting me know 😀
Where is the kite,the isosceles trapezoid and the right trapezoid?
Ah yes, you are correct, I haven’t included those shapes. I make these videos primarily for my own students, and the kite isn’t in our curriculum. We do cover Isosceles trapezoids later in the unit, so I guess when I made the video I wasn’t up to that yet. Thanks for pointing that out 😀
Where is the kite and the isosceles trapezoid?
Hi Mr A I really enjoy your lesson because your video always brings me into right direction and also with brilliant ideas which my teacher don't teach me. Thanks.
Thank you so much 😀 It’s great to hear the videos are helping you.
I used to get totally confused to work out the angle of depression and evaluation but now from your video I get to understand and I want more of your video. Thanks
Oh that's terrific. Thanks so much for letting me know, I'm glad the video helped you understand 😄
Well done
Why thank you 😀
One paper this works since angle and one length is given but in real life, if given the hyponuese, angles becomes useless. Climbing a tree is easier than using a tiny protractor on meters long paper to measure angle.
Hey, thanks for watching and commenting 😀 I’m not sure I follow exactly what you’re saying. In practice it’s much easier to measure angles in real life than it is to measure distances. I suppose it all depends on what you’re trying to do. These days if you wanted to know how tall something is you could just send up a drone with an altimeter- but if you go back 40 years or so, it would be much easier and more practical to measure a distance away from the tree on the ground and then measure the angle of elevation and use some trig. That’s more or less how all maps were created before we had GPS. Surveyors would pace or measure out distances along the ground, and then measure angles between points to calculate other distances. Climbing tall objects also introduces many risks that walking on the ground does not. It’s also worth noting these are sanitized examples designed to allow HS students to practice basic skills and don’t accurately represent the many additional complications you would encounter in the real world. For example, over long enough distances you need to start taking the curvature of the earth into account depending on how accurate you need your eventual calculations to be.

Hello! I noticed you stored some numbers in your calculator as A and B would you mind sharing how to do that on a calculator? I have a Casio fx-300ES PLUS
I’m sorry, I’m not familiar with that calculator. If you google the manual you should be able to find how to do it, or search RUclips for a video.
me watching it in 2024.it helped a lot. thank you
Hey- that’s awesome! Glad it helped you out 😀
