Seeing jan using the 3d printed pinky makes me smile
I hope one day Jan gets an Ian Davis level mechanical pinky.
@@mf-- yeeees!!!
Honestly 5 years ago i never thought one day we will have Wren and CC talking about PIDs and Mahonys...what a time to be alive.
Wicked talk. Fortunately, the battery situation isn’t really that hard anymore. I published a video and write up of a great configuration that fits in the XR box with no modifications, that works with a couple of aftermarket BMS models.
It’s great to see the spread of the DIY spirit. Wonderful podcast.
So guys we're officially calling DIY Onewheels Funwheels. ok? ok.
Crazy how much the ride has changed just from FloatLife Fest haha, I raced on it to help bring in attention to VESC and push it forward, but I'd be absolutely lying if I said it wasn't sketchy 😂 Now, with Mitch's IMU filter and my own tune, I can pretty confidently say I enjoy my VESC board more than I have any board from FM.
GT power (and beyond) in the XR platform is truly the best of both worlds, and like you guys said, this is basically the perfect outlet for enthusiasts who are after hyper-specialized setups that Future Motion just isn't in a position to offer. I've honestly never been more excited about the future of the sport and can't wait to see where things go from here 🔥
Niko has such a calm reassuring way of giving instructions. He could talk me through building a VESC board, or through an emergency tracheotomy on someone asphyxiating and I feel like I could manage both without losing my cool 🙂
Just FYI, the bar isn't nearly as high as everyone is making it out to be. I went from zero electrical knowledge last August when I bought my first XR, and built my vesc just fine. There were a couple speedbumps cuz I was so inexperienced but the online knowledge and community is there to help and back you up. Love my 84v vesc now. Hit 32 before pushback and I weigh 190. I'm also just a factory worker so you don't need to be loaded.
That last sentence was the most important for me haha
I know I’m late to this comment but this is really reassuring! I just ordered the makers pev Foc kit and I can’t wait to build up my board! Planning to jam a 19s2p pack into the badger torquebox.
Yea it just takes a willingness to tinker, and not be afraid to burn some money if you burn out something. That said I feel like having a FM board to compare my tuning to really helped me figure out what worked for me and what didn't and really nail my tune.
You can buy the front footpads with sensors off of us too...and they wont ghost😉
As someone who built their own VESC as their first (and only) onewheel, this is a very interesting podcast!
Hell yeah vesc onewheel ogs :)
But where did you get a hub motor? Aren't these built with FM's hub anyway?
@@ac.creations floatwheel.com once had a pint sized kit with controller, hub motor, rails, footpads and battery
But these now they only sell their new "adv" series which should be a GT killer
But other than that I belive spintend sells a hub motor as well
I'm the sort of person who saw a onewheel for the first time and my first reaction was "how do I make one of those" and when I realized it wasn't possible yet at the time, I said "I'll wait." I think it might be time.
yeah I'm the same way. all the problems described here are just working with the existing platform. I built my own electric mountainboard but now I think I want to move onto making one of these.
Jan nailed it. Hearing people talk with passion is one of the greatest joys in life.
Hey guys. I'm about to tear down an old Plus and convert it into a VESC. I've got an XR, a Pint, and this soon to be VESC Plus, with about 2k miles between all three boards. I loved this episode for a lot of reasons. First and foremost I think it really sums up the current feelings of the Onewheel Community on a variety of topics. From Jimmy Chang to Bodhi, we have all said we love the GT, but he hate the turn away from mods and ability to DIY your board. You guys nail the justification for why VESC is growing rapidly right now, what's right with the XR, what they nailed with a GT, and why we're unhappy. You also do a good job of defending FM, who does hold a lot of liability and risk associated with making this happen. I appreciated your takes. Second, this serves as an amazing record of where we're at. In a few years this video is going to be more of a record of vesc history than a build guide and that's perfect. This is one of the most complete archives of where the community is at on building vesc boards and will serve as a source of reference for a long time! Last, you guys show the best parts of the community. We just love to ride. We love our boards. We want to be able to make our boards the way we want to, unique to every rider. You guys hit the nail on the head again and again, and make me so stoked to get out and ride. Float on my friends!
I want to say in addition to this, the discord channels and subreddits for onewheel, funwheel (fungineers), and the vesc project are amazing resources that you should check out!
Wren sold me on onewheel 2 years ago. I was pandemic shopping for a bike. At my big and tall size it would have been 2k for a bike that would last. Ended up renting onewheels for an anniversary and had one 2 weeks later.
I'm an average rider (15mph for me) and have put a JWXR battery with a third party shop. 3k miles later and it is absolutely my vehicle for many purposes.
Niko: "Step 1-"
Wren (under his breath): "... cut a hole in a box..."
🤣🤣🤣
I've been making electric skateboards and battery packs for years. You can totally build your own battery pack with as many cells in series and parallel as you'd be able to fit within the frame. Source your own BMS and solder it in accordingly. Simple enough and it would make a good crew video I think.
Cheers!
The problem isn't the fundamental creation of the battery pack. I can do that. In fact I HAVE done that before. The challenge is fitting the battery pack within the frame. THAT is the wall we're already running up against. A 20s2P pack is just a litttttttle too big, but with VERY heavy modification we got it to work.
I also wouldn't trust a lot of people to be careful enough with the batteries to build their own packs. You've got as much energy per weight in a lithium ion battery as TNT and while not as explosive, it can have very catastrophic failures.
@@SirWrender Pretty sure Mario Contino recently said he'd be temporarily building 20s2p packs. He also gave some good suggestions for BMS options but I don't know if he's providing his own czcams.com/video/Oxrt1soLs9w/video.html
With how clumsy some people are (me) and even simple soldering might not be the best idea when it comes to li-ion batteries. I'll leave it to the ones with experience who have done it before
as a university student that is studying as a engineer I find myself wrestling with the ideas of modern transport the one wheel is amazing. Much love to the continued knowledge that has been shared though this channel and community another great podcast.
Same here. Cant afford a onewheel on a college budget though 😢
This is just epic, can't wait to build my own VESC and break some bones!
hopefully at most your own...
@@quinnfoster1234 just imagining absolute mayhem of this guy rolling around swinging a flail at passers by haha
I appreciate that you guys take the time to explain things for us that don't really know anything about Onewheeling. I know you've spoken about it in the past, I don't have a horse in this race, but even if I don't have a horse in the race I'll still watch the horse races. Thanks for the podcast :)
Excited to see so many content creators jumping on covering VESC at the same time it's going to be good for the marketplace and the community in the long run
Great podcast! I’m lucky enough to have smart friends with dope vesc settups.
Little misinformation at 26:18. The battery is actually one of the cheapest components. The bms is $500 used because it’s proprietary. Batteries with low mileage and are $80-150 tops for xr or pint because of chi batteries
This feels like a Windows vs Linux discussion, but civil
Perfect. I was just researching building a vesc earlier this year, but got a little discouraged by FM shutting down an outfit selling a near complete kit plus reading the firsthand accounts of those that had tried. But now? Seems now is the time
Hearing a madcat like Wren say 20mph is the sweet spot for "fast enough and don't really want to go faster" making me realise how dumb I was going 40kmph on my board. Yes, my elbow is very much held together by metal. RIP.
Average max sprint speed is ~19 mph, so at that speed you can still technically run out of an accident or bump. Makes sense that would be the comfort limit for most.
@@ZacDonald yeah which is what I typically did on my traditional boards. Very good points thanks. Unfortunately this one was a slip, no running haha. Elbow straight into road. I was like the rock and people elbowd that road haha
Yeah, but now you have below the skin metal shielding 👍so if anything you can go even faster! 😎
@@xavicon64 time to unlock 5th gear 😎
I remember having a short interaction about my VESC build on Twitter with Wren in like 2020, it has come a far way now :D
You guys are the people that made me discover Onewheel, and now I have two of them ! So thanks for introducing me to the wondeful world of floating !
I like how the random guy in the background at 1:45:19 gets on to a onewheel 🤣
Thank you for making all of this possible!
This is great info for an unexplored opensource hobby , i have a plus conversion planned once all parts are in!
The PC building analogy definitely instilled confidence!
I say this in almost every videos on Corridor about Onewheel but I'll say it again, you guys are the reason why I got a used Pint even though living in Asia where Onewheel is rare and hard to get.
I got a good XR deal months later but it was lost in the transit, and there's no way I'm getting my money back. Filled with anger and desire that I SOMEHOW HAVE TO get my hands on one, I got into the VESC community and have been learning to build one albeit that the components are pretty hard to get right now but I'm pretty stoked - the future is VESC (for the rest of the world).
You mean building a vesc board like soldering all the components together ? I’d love to do that
Niko better take back that "not Floatwheel" statement!!!
Thank you and thank VESC !
Given the amount of moderate to heavy injuries I've seen you guys sustain when riding those things I'm not convinced they are that great an option to get around the city.
Could be said about any means of transportation though, especially if people ride them without protection.
Consider though that most of those injuries were from tricking and distracted riding though. With any transport making smart choices is always going to be the biggest factor in safety.
There’s been this judgement on VESC that I’ve seen because earlier firmwares that people had worked on wasn’t amazing, but with the software being as… honestly daunting with every little variable being able to be changed and laid out in a fairly technical way, I knew that people just needed time to be able to really hone in on how to make everything work together and fully understand it all. It’s a complicated device with a lot of components that rely on eachother to work and not harm someone by dropping them. Not as straight forward as a bike motor or longboard motor.
as a fellow rider, I greatly appreciate this being uploaded :)
Just FYI that the link to Indy Speed Control for the battery is not working. Otherwise, love this video and love you guys! What great service this is for the community. Thanks!!!
I got my favorite XR off craigslist for 1400, only had 136 miles on it and came with the hypercharger and tonnsss of accessories I was going to get anyways
OMG YESSSSS I've been waiting for this podcast for so long!!!!
I have a OneWheel which I ride for fun and I love it, but I never travel with it because it's just so inconvenient.
When I'm not having fun and just need to go places, convenience is most important to me.
The OneWheel is slow, has short range, no suspension, long stopping distance, when you're not riding you have to carry it and it's a heavy awkward shape to hold.
I commute across a very rocky gravel road and farmland at 30mph which would take me twice as long on the OneWheel and I would risk injury every day.
Again, even though I love the OneWheel, I see it as more of a quad-bike: a fun recreational activity, but not a serious mode of transport.
Onewheel AND Opensource? you go me hooked
This episode convinced me to buy a One Wheel 😅. I was waiting to see how the open source stuff matured, but you convinced me to learn on a real board before trying the DIY route.
If you only plan on JUST riding get a stock onewheel.
If you will need ANY modifications, start Your vesc build
I'd suggest a used XR. You'd get to experience the sagginess at under 50% battery (going back to the foot control you get from riding a V1) and by the time the battery gives out, you can upgrade it and reuse a lot of your hardware.
The Indy Speed Control 20S2p with included BMS is verified to fit in an unmodified Stock XR enclosure!
Yes. Love it. More onewheel
Love u guys. So I'm looking to build to build a 84v vesc. I'm a bigger guy and want all the extra power. What would the mileage be on a 84v? Less than a CBXR?
nico explaining a pid loop is something i never thought would happen. on a second note, do their vesc have a blackbox ? in fpv quadcopters is a really powerful tool to tune the pid just right
Yeah it has everything you want
Bro I didn't even know there was a one wheel festival in bentonville, and I live here.
can't wait for the Corridor Cruise video!
While I do love that side stance of a OneWheel coming from a longboarding background, people like Hayden Wu and their carving on an EUC look so awesome
Check Smarter Every Days video about the helicopter thing. If the engine dies in your aircraft you are MORE likely to make it in a helicopter, because you can pretty much always make a soft(ish) landing by auto-rotation. A plane can only glide so far to find a large enough open space to not crash when landing. The helicopter only needs to find a tree/building free area much smaller than what the plane needs to land safely.
VESC is the future
Jan this whole podcast: "Sure sure sure"
The D value or Derivative actually reacts to a sudden change. If you imagine the difference between desired tilt angle and actual tilt angle as a function and take a derivative of that, that is what the D is multiplied by. The derivative shows you the rate of change of a function. I can finally utilize all the suffering through control theory at the university 😂
You can get just the front sensor from Future Motion if you send them an email. Recently did it with a Pint ($60) and an XR ($100)
Interesting
I love my OneWheels (Pint & GT), they are much more fun than my EUC (V8F), in my opinion. However, I completely disagree, IMHO, with the idea that a OW is better at commuting.
Louis Rossman has a fantastic video about One Wheel and independent repair. I'm of the opinion. That I should be able to repair. Service or otherwise modify anything that I purchase with my own money. I expect that with that freedom, comes responsibility. Fundementally, everyone wants to pass the buck.
They talked a bit about Louis Rossmann's videos during the last podcast talking about the Onewheel.
Did you listen/watch this podcast? This company is run by by lawyers and unfortunately those 70 or so lawsuits is holding the company back. I wouldn't be surprised if Future Motion goes kaput in less than 10 years. Louise is a great advocate for right to repair but his One Wheel rant just came off as loud and angry on a product he's never any experience with, I'd rather to people wreen & Niko who come off way more objective and actually used a one wheel.
@@ronch182 Honestly the impression I got from this podcast is that Future Motion is the kind of company to strong arm you into only saying good things about their company if you want to maintain any sort of functional relationship with them, they clearly don't have the competence or the funds to offer proper services to their customers yet they go out of their ways to ensure you are unable to repair your own device anywhere else and create as much of an anti-repair device as they can all while holding their patents hostage, their strategies are exactly what's holding them from growing and if the company goes downhill no one is to blame but them.
@@ronch182 I recommend you watch his video with Josh Haley from Boardworks, it goes into specific details about this company. I don't understand how a lawsuit could hold any water after the board has been modified by the end user and the fault is generated by that user.
Theres a consistant fanbase of who view products as a Utopia. "You shouldn't open a macbook, you shouldn't open an Iphone!" Batteries are wear components, and to brick a machine after replacing a battery is a tactic to generate revenue. You can't convince me its about safety, especially when FM could sell replacement batteries when they don't.
Its about money.
@@ronch182 Did you actually watch Louis Rossmann's videos interviewing guys that specialize in repairing Onewheels? The bricking the board when the battery is unplugged is a universally criticized move of Future Motion. Try watching "A talk with Mario's Board Garage about Future Motion & the Onewheel" and "Introducing Onewheel repair wizard, Josh Haley from Fiction Factory Boardworks".
sponsor message is such a throwback to ep 100 :)
Man, i wanna get into vesk! Getting onewheels on Norway is stupid expensive
Lol. Everyone else is putting up halloween related videos.. and here you are with one about onewheels! 😆
Though I'm totally here for it! 😁😁😁
Hi there Corridor Cast!
Any tips for someone to begin their one wheel journey? Like a 'training wheel' model so to speak.
Thanks!
yo could you guys make or link a shopping list with all the things you need and possible places to get them?
description!
Okay so I have no experience with one wheels outside of Corridor Digital for the last several years. Is it time that I get one/make a VESC? Seriously is it worth it? Great podcast btw, not just this one the whoooole Fam Damnly.
Absolutely get one, it is the best purchase I've made in a while. Without having tried a VESC I would recommend getting a Future Motion board first to get used to riding. It takes so many miles to get comfortable and understand how to properly ride and they make it very user friendly, jumping in on a VESC I would think would create a more negative experience than it should.
This sounds cool from the title. Let’s dig into it. ✊✊😎
You can still pick up eucs and they also just roll down the stairs no carrying necessary.
Loved this one. Can we get another conspiracy cast with Jan again someday?
I think the issue with FM as a company and VESC is that Onewheel has become somewhat like Velcro. Any device that looks like a Onewheel, in the eyes of a layman, IS a Onewheel. FM has such a monopoly on one-wheeled skate-stance electric boards that it's becoming a problem for them, since their community is making aftermarket batteries, modified controllers, and this and that. FM has been in the game so long that they're always going to hold liability in the public eye for things that may not be their fault OR their product, as long as it occurs on something that resembles a Onewheel. That's why the word VESC leaves a sour taste in their mouth, because soon the community will be flooded with fully-custom boards that have zero FM parts and still look like a Onewheel. I can't wait 😎, competition breeds innovation.
Actually at high temperature the stator lost efficiency meaning even if you push more current to it it doesn’t output the increase magnetic force.
I'm not sure but I think future motion also has a patent for the design (and any similar one's). Like this format of E-mobility format. So the onewheel name, they have a trademark...but also have a patent of the design format of a onewheel. Correct me if I'm wrong.
Look up the trotter. Clearly this isnt water tight argument.
The parts are as easy to get as FPV drone parts if you can make one. Nobody owns the drone design.
Have you checked bajaboard? All terrain electric skateboard, they’re awesome
Propel endeavor is better for $
Wow. A mode of transportation that I never knew I wanted until now... But where would I ride?
Anywhere! That's what's great about them. Street, dirt, mountains, doesn't matter 😁
Do you think it’s possible to find schematics of the vesc and solder everything together (or at least order board with smd and solder the other components ?)
Yep! Look up the cheap FOCer. It's designed by the same person as the VESC based ESC seen in this video. It's less than $100 if you solder it yourself. The next version is releasing soon ish.
Haha so cool you mention it bcs I was doing some research about it actually ! Do you know if it’s gonna be before the end of the year or not ?
@@philou1234 you can get a little focer in the mean time ;)
You can make a vesc for sure by getting a pcb and line traces printed and soldering components on it.. you then need something that can take arguments in logic like a raspberry pi or a arduino.. and a bunch of relays .. its doable ( the first ever onewheel was a arduino board ) but not easy
I’m in!
What brand of headphones does Jan have around his neck? I see the crew with them all the time and I’m trying to get a pair
What about winter tires for a one-wheel? I live in Norway, i can bike around in the winter using snowtires for my bike, does it work on a one-wheel?
Yes! People have made custom snow tyres for the XR
you can put a tube in and diy stud your tires lol
You guys should put this all together into a diy kit and sell it on your merch store.
With a huge disclaimer that "you are not responsible for what you do with these parts"
Maybe even call it something stupid, like "random electronics parts"
they could sell their custom tunes!
@@quinnfoster1234 i just want one pack. I'll pay a premium.
Shipping to Norway is so expensive and time consuming that I'd rather just pay $500 ekstra and get it all in 1 package
I'm NEW to wanting an VESC, Adventure EV, Onewheel, but motivated and ambitious Is there any solid shops where I can find used onewheels and the Vesc up grades online that you could share?
so how much to have the corridor digital kit? haha they buy everything and send it to your door (in Australia ;) ) in a package and have links to the DIY assembly, where wren is not allowed to explain the process unless supervised by niko incase we hit an interesting topic n the board never gets built haha
I absolutely love the concept of the onewheel. However, given my location it's impractical as a means of transportation, so I could never justify the price
The timing on this is impeccable. My XR fried it's BMS just outside warranty. Future Motion will not sell me a replacement BMS, they want me to ship the entire board (at my expense) to San Jose from Miami, then charge another $60 just so their techs can confirm what I have already diagnosed. I'm so over this company.
Repair stations in Europe don't really matter, because Onewheels are largely illegal over here, and only rich people who buy it to ride on trails once a year have them. And they can afford shipping to cali.
put four of them together and make a speed racer car
Would rather have a Cybertruck with 20 Diy boards in the back.
You mentioned that charge-and-ride is sketchy. On a VESC, is it sketchy from an electronics perspective (if the physical stuff like quick disconnects and protecting the port is well-handled?) Is running a parallel battery like Wren described for the enduro race less sketchy? Until we have swappable batteries, it seems like one of these is the best choice for long uninterrupted rides, I'm just trying to get a handle on whether it's a bad idea even if implemented well. Thanks for the video!
There's a slight risk but electrically if it's set up right it should be okay. If you use two different batteries and one of them is weaker than the other that can cause a problem. Also wiring coming out of the board is quite exposed and could be shorted so you definitely have to have a fuse.
"Charge-and-ride" as it's specifically implemented is sketchy simply because it's not how it should be done. This routes power through the control board's charging circuit while it's being used. The purpose is to use another battery in parallel, however the Onewheel prevented that so the CnR method was really a hacky compromise.
The better method is to splice in another battery in parallel directly into the battery wires going into the Onewheel. THIS is how it should be done, and is fairly common practice in other PEV vehicles like skateboards and bikes. The sketch factor here comes in that you HAVE to make sure the two different batteries are at the voltage / charge level. If not, it can overload the other battery and cause a fire. If they're sync'd then there isn't an issue!
@@SirWrender "floating" voltages should match 😋
@@SirWrender Thanks for the reply Wren! I suspected as much, I was just imagining CnR might be less sketchy in a VESC with a separate circuit and a charge-only BMS. And yeah, keeping the batteries at the same voltage in VnR seems like a hassle. In any case, since my comment I've been thinking more about swappable batteries as the solution for longer rides. Mario Contino's 20s2p pack looks like it would fit between the rails, so I'm thinking a gasketed battery box lid that hinges up taking the footpad with it might be possible. Then a quick release lever (like on a mountain bike wheel) at the tail to lock it down and apply pressure to the gasket. My Little FOCer is in the mail as of today, so I'll start with a simple build and then consider getting fancy.
Gues you never get invited to FM events annymore 😅..... you guys rock💪
Would increasing the torque at high speed be considered a brake? Would it be possible?
maybe could try it
My XR has lost torque. It’s gotten easy to push the nose or tail to the ground. Overall seems to have less power. I changed the battery out with another used battery I bought off eBay. It did not make a difference. I wonder if I bought a battery just as bad as the one I replaced it with. Could it be my motor or do you think it’s still need a new battery?
I just can't get over how these things are still so damn expensive! Normally building yourself is cheaper but this looks like it would actually be more expensive once you're done. Is there no way to decently build these for a grand total of around $500?
Not atm
I have almost 2k miles on my XR and I think I'm close to needing a new battery. Under 50% battery it gets sketchy. What have others been getting for lifespans on the stock battery?
Also I might save some money for an EUC
You've likely long since discovered this but drain your battery to 0% and then charge it for 2 days .. balanced decks make a difference. 30,000km ridden here .
@MrDmadness I've definitely left it plugged in for many days before. But specifically i need to drain it to 0? I don't think I've been below 20 because it's just so dangerous
You absolutely need a BMS. Without it, the battery will eventually blow up when your charging.
No it won’t. The controller acts as a BMS when charging and riding. It can’t monitor the individual cells but it DOES monitor the overall voltage. So it does prevent overcharging and overdischarging.
The man. The myth. The legend. 😎👌
you have a BMS, just not in the board. That is where it is safest for the rider.
Wow, big fan!!!
While I respect your opinion and most people will likely get away with not having proper protection circuitry on a batty, there is a high enough possibility that one or more of the cells voltage will diverge from the rest of the pack, that it's probably best to not recommend it.
Unless you have a Analog Front-end (AFE) monitoring each cell you can't guarantee the safety of the pack.
Over discharging a cell is less likely to cause a problem than overcharging will, which is what happened to me with my unprotected 12 volt auxiliary battery on my 1985 Honda xl250R electric converted motorcycle. My battery blow up while charging after about a year. I thought that I could get away with it by checking the balance of pack with a voltmeter regularly, but I went a few month without checking and boom 💥. The explosion actually dispersed most of the cells so there wasn't much left to burn and I managed to save the rest of the bike:)
I understand that modular BMS systems can be pretty expensive which, is why I made my own based on the BQ76952 from TI with active cell balancing. That said, there are some cheap enough options, that it doesn't make a build prohibitive. Especially if you plan to charge overnight in your home.
Again big fan, I love how you've made science cool when your have the chance in your videos!
P.s. next time you are in San Francisco, come try my motorcycle, or checkout the onewheel night ride:)
@@steevethebeeve yeah external balancing regularly is the trick. It's about as dangerous as making a diy gasoline pump then if you let that go unattended in a unsafe space, that's on you.
47:43 .. You are welcome
What is the total price for the build?
My fastest onewheel XR speed so far was 29.9mph😬
That's so cool! Thank you for informing me about that, i almost bought one, but the whole future motion anti-repair is a big no go when in Europe.
Also vesc is the name of the esc inside the board no ? Why call it that way, really confusing
calling it a VESC is just for differentiating the DIY onewheels from the Onewheel by FM, there are different diy "brands" like floatwheel and funwheel/fungineers
@@caution0001 yes but i wouldn't be calling my drone a "betaflight" or my gps a "u-blox" or my laptop a "intel"
Here's your chance to come up with something catchy that doesn't evoke a e-unicycle and doesn't violate Onewheels trademark.
While I understand that FM would see VESC as competition, I don't think the need for VESC would be as prevalent if not for all the issues with the GT and what in my opinion are poor choices regarding right to repair.
Regarding speed limits of the GT, I'm sure those that are willing to spend 23 minutes watching the podcast may have already seen this video, but if you haven't, here is Jeff Adair clocking in 32mph on a GT. czcams.com/video/IwHTTA4uKJM/video.html.
Something like this is pretty much exactly what I was hoping for! Suffice it say, and to probably very few's surprise, I am not exactly convinced of the quality of the onewheel GT. One of my many gripes with the GT that changed for the worse from the XR is the rails going from being anodized to powdercoated. Specifically because of how powdercoating negatively affected heat management. Now, I'm no laywer but you'd think one can reasonably assume that if you inform someone of any/all potential risks of trying your VESC, and they make the choice to do so in spite of that information, and were not forced to, the responsibility would fall unto the person who made the choice. I'd at the very least expect it to carry some weight as a part of a greater legal argument.
For anyone who needs help with building a Vesc, or has questions in general, the Vescify D1$C0RD (code to keep from triggering the system. Comment keeps getting deleted) Server and the Funwheel server is a great place to start. It has a lot of helpful and knowledgeable people who are willing to help. I don’t think I can put a link, so you might have to do a little digging to find it.
I wonder how the downhill thing works on a onewheel, because surely it's not just going to accelerate forever, right?
Nope. It will accelerate to about 20ish mph- depending on your weight, and once it reaches that speed it will lift the nose, forcing the tail down, causing you to slow. IF you push past that the board will drop the nose to the ground and shut off, effectively increasing acceleration to an unsafe degree. No more magnetic balancing. No more braking. You're kinda f***ed at that point.
Respect the board and ride within your abilities. 👉😎👉
@@KING_PHILLIP Thanks! 😁
Yea I actually hate FM and want nothing to do with them. I have a float wheel and just love it and feel so much more confident on it.
But when people ask me about it I just say its a onewheel, cause the onewheel really is a finished product in a way that not even the float wheel is, and I want people to enjoy onewheeling. Plus once their hooked I can always turn them to the dork side with more ease.
I'm thinking about getting one but does it hurt your legs after a long time of riding?
I assume it'd be like riding an electric skateboard mixed with riding one of those hoverboards from like, 2017.
if you do longer rides it can start to hurt.
In my case my feet, knee and thighs sometimes hurt/ache (not at the same time)
However over time you build up these sore muscles and you can do longer and longer rides
I'm doing 8km (5 mile) communtes twice a day for uni, in the beginning (1.5 years ago), it was pretty tough bu these days it without much trouble at all
@@caution0001 thanks,👏 so ama get stronger legs.🤣😂
They make padded footpads if you want more comfort
Check your local facebook groups. Float life/stoke/onewheel, ect. They'll have friendly people willing to meet up, talk about it, probably even let you ride one.
Its a very very friendly community. 🤗
You know how some japanese electronic giants of today started out as bicycle or baseball card manufacturers like 70yrs ago? Imagine corridor becomes a top ev vehicle manufacturer in a couple decades. It all started here.
"Corridor Conglomerate: Your corridor to a brighter future." Just don't accept contracts for hunter killer drones for an unrestive populace.
YUHHHHHHHHHH
I have no idea how wren is invited to commentate official onewheel events while also ramping up right to repair in his personal channels. I hope increased pressure causes FM to change.
He got uninvited from the last event after he *briefly* mentioned VESC/R2R while also gassing up the GT on another podcast. Maybe why they went full send for 2 hours, they have nothing left to lose with FM.
Shout out my one wheelers
Well the floatwheel part didn’t age well😂
