Post high speed here! OWheelbuddy app

[dcosmos]

@thehoff very nice but technically, it was a 270.

[thehoff]

@dcosmos lets not split hairs here! im lucky if i can do 180 and ride out in switch

How fast can you go over grass?

i haven't run Owb on blacktop yet but was surprised to hit a 22.4mph burst on a flat bumpy grass track i ride.

@MichaelW said in Post high speed here! OWheelbuddy app:

What happened to posting your highest speed... We got off track... lol

Yeah, stay on topic people! We're talking about Onewheel high speeds here! And while we're at it, what's everyone's favorite movie?

[mrb]

@thegreck

i was thinking The Gods Must be Crazy, as i was hurtling to my knee after a nosedive at 18.5

[thehoff]

@thegreck sorry,, we did get a bit off track yesterday. But hold on..... @groovyruvy and I are trying to bring the onewheel world together. This is history in the making. Ireland rider comes to LA for first transatlantic meet!! 😏😜

[RLY]

First day of riding. 17.8

[RLY]

Second day of riding. 19.5 mph. Age 36. No helmets, no pads. All pavement.

[thehoff]

@RLY please be careful.. Most nosedives happen in the first month or so.. Enuf said

[MichaelW]

Impressive @RLY but careful in the beginning.

[RLY]

@thehoff @MichaelW Thanks. Everyone's wisdom hidden in this forum is pretty helpful. There should really be a 2.0 of the owner's manual.

[slydogstroh]

I've only had the app for about a week, but so far my high speed is almost 23mph! I ride in a local Boosted Board group and have had no problem keeping up with the other riders.

[thegreck]

@slydogstroh WTF???

[Hubbitron]

Srsly I can get that in a burst but going beyond pushback is terrifying. This board needs to allow a bit more speed.

[MichaelW]

A new high! Holy shit... Like a boss!! @slydogstroh

[frotozoa]

18.5 mph. like a 3 second burst.

[Hubbitron]

@slydogstroh how? Mine is ready to throw me just past 15mph. Tell me your secrets.

[slydogstroh]

lol @Hubbitron - No real secrets to tell. I keep it in extreme and ride on Lakeshore Path here in Chicago to work every day. The path has a nice long straight away where I slowly build up speed, feeling out that acceleration limit of the board. I hit 21mph on almost every commute.. but right around 18-20mph is the sweet spot where I tend to cruise.
Every once in awhile I will find the pushback is stronger and the nose of the board raises up a bit more. I use this opportunity to fight the pushback and gain just a little extra speed. BAM. ~23mph.

It also doesn't hurt that I have put over 1700 miles on my board in the last 10 months.... ;D

[mathfreire]

So today coming back from work got the notification for top speed, a bit after I passed a boosted board rider, 26.5 didn't really think that could be possible, tried again and got 24.6

[dirtyjersey]

5$ for the app though?? I'll stick to the lame one wheel app

[LidPhones]

Ok... Time to buy. Too many good things being said. Just take my money. LOL

[sonny123]

Just downloaded pOnewheel and hit 13 mph.

Now being the chicken I am,
I know I never go past 8-9 mph.

Methink these apps are little too optimistic.

[groovyruvy]

@sonny123 said in Post high speed here! OWheelbuddy app:
Methink these apps are little too optimistic.

Yea Bro, agreed!

[thegreck]

@sonny123 The speed shown in the OWheelBuddy app is computed based on the rotation and diameter of the wheel, so it's super accurate. The GPS-based apps are hit or miss, though.

[Hubbitron]

In that case the OG app and pOnewheel are both underestimating the speed and the device goes 5-10 mph faster than FM says?

[LidPhones]

@groovyruvy & @sonny123 yeah seems that the margin could be + - 20% or more. Does anyone have access to a radar gun?

[groovyruvy]

@LidPhones based on @thegreck's note about OWheelBuddy computing speed based on rotation + diameter of the wheel, that app should give pretty accurate readings. I don't have a radar gun to test. Seeing others ride is one gauge I'm using, and I've just not seen riders hit some of the really high speeds that are posted here. I'm no slow poke and even on steep downhills past pushback I've not hit (per my own estimate) more than 20-ish MPH.

[LidPhones]

@groovyruvy

I agree the per the method of speed calculation the OWbuddy app should be spot on. I just downloaded it so I can check it out and see where I am at.

[slydogstroh]

ayyyyy sooo stoked on a new high!!! Was just a commute ride too!! @mathfreire You're on man.

[MichaelW]

I can't believe this! How can people get going that fast!! Unreal... Bravo @slydogstroh

[sonny123]

Well, going the old fashioned way. Found me an old bicycle speedometer laying around.
I think i got it pretty close as the smallest tire circumference is 100 cm.

According to my friend, it should be:

If the diameter is 11.5" then the circumference works out to 91.76cm.
If you entered 100 then it is going to be true about 91% or report 8.2% higher speed.

[groovyruvy]

@sonny123 I dig the tech talk, work at the bench, field testing video and documentary photos- it's awesome! I'm learning a lot from all of you with mechanical and engineering abilities. My technical skills are such that I can charge OW, inflate the tire and use the app. Oh yeah and I can clean the board. I also changed out the footpads once. Woo Hoo. Beyond that if your findings are accurate it seems to suggest speeds are over-reported.

[jordo]

This conversation is cracking me up. The owheelbuddy app is using good ol' fashioned math calculations, tough to dispute. This is almost as funny as trying to blame nosedives on hardware/software failure (almost).

[sonny123]

@groovyruvy

Pretty darn accurate.
Just did a test run and rode side by side with a car while he was giving me his speed.
My guess it's within 5% over reporting.
I usually experience pushback at around 11+ mph and did just that.
My average all around speed is actually 10 mph as I thought it was less.

[dirtyjersey]

Not gonna lie I had to get it just to see how many miles I have on my onewheel that's pretty dope

[sonny123]

https://www.youtube.com/watch?v=iwlwmqKYOjg&feature=youtu.be

[mathfreire]

@slydogstroh hahaha nice man 24 is pretty good!! Going to work and back never been so much fun! And I used to have a boosted board before my onewheel!

And yeah I don't get it why does FM says the board top speed is 15mph and only 5-6 mile range

What kind of mileage do you get on your board with one charge??

[sonny123]

Sure goes way faster with no load.

https://www.youtube.com/watch?v=x4njY141b1k&feature=youtu.be

[slydogstroh]

@mathfreire Depends on the terrain. At the boosted meetup a couple weeks ago I got 10 miles on one charge because we were going over bridges with large downslopes at the end and the regenerative braking charged us all back up. My commute is 5 miles long, pretty flat, and I usually have about 30% battery left.
In my experience, 22 mph top speed and 6-8 miles range is more accurate, as I hit those numbers consistently.

[Hubbitron]

I stand corrected.

[No]

18.9 is my max speed, after that the OW cuts out, but I weigh 215 lbs so that probably has something to do with it...

[frotozoa]

@dirtyjersey
I bought a tablet just to use the android app and wish I wouldve waited for this app. I wanted to see the total miles and thats the only reason. But the apple one light function works and the android app doesn't. I think android is like microsoft. They make you keep buying hardware to run the newer software.

[LidPhones]

15.9 MPH so far.
I think that was achieved on my down hill carving as the OW nose was pushing back. That is plenty fast for me and it remains fun. I do not want to tempt the OW limit and taste the ground.

As a side note the GPS app Strava showed the same max speed as OWheelbuddy.

[Hubbitron]

@LidPhones I hit over 21 mph last night and it nosedived but I was able to run it out. I am mentally prepared at all times for this thing to dip and if you use the momentum of your rear foot being thrusted forward by the rear of the board kicking up it puts you into a sprint.

[hustle]

19.26 is mine. I've hit it twice now.

[thegreck]

@Hubbitron Top speed run-out... love hearing that!

[skideeppow]

ok now i am feeling like an idoit. I can not figure this out. I delted the app and reloaded it as well. Still in metric.

[kelp]

@skideeppow press your home button, swipe down, type 'settings', scroll down to OWBuddy app, tap it, change from metric :D

[kelp]

havn't seen it mentioned yet, but another bonus/feature of the OWheelbuddy app is that it has GREAT integration with the Apple Watch!

[skideeppow]

@kelp ok, the only options i have are
allow notifications
show in notifications center
sounds
show on lock screen,
then alert style when locked.

I will update my iphone 6s and see what happens.

any other thoughts?

[kelp]

yea you might need to update ios. what version are you on?

[skideeppow]

that was it, updated i phone and worked. Thanks for your help

[thegreck]

@skideeppow The settings you listed are for Notifications, so I think you just went too far the first time and clicked on OWheelBuddy and then clicked on Notifications, instead of staying in the OWheelBuddy settings.

[kelp]

@skideeppow np man i help people with their iphones a lot :P

[depressedguy]

Did a speed run just now during my regular commute. I could upload my helmet cam footage if anyone's interested😊

[dcosmos]

Would definitely like to see any video of your top speed which equates to 27 mph which is unheard of.

[Polle]

@depressedguy Sorry, but I really think this is not correct?

[Hubbitron]

It's in metric units.

[groovyruvy]

The top speed can be gamed

[ahxe45]

@groovyruvy I totally agree. I honestly don't believe 90% of these speeds are even close to accurate. I tested this out last night using a radar gun and OWeelbuddy was telling me I was going 25mph and the android app was telling me I was going 27mph and the radar was saying 17mph. I have hit 22mph using one of the slow down radar signs and my board felt and sounded like it was about explode on top of not having the self balancing anymore.

[ahxe45]

I don't believe the board is even capable of going 25+ I think it would just shut down at that point because like I said the board sounds awful once you go past pushback and you can feel that it is being overworked.

[Hubbitron]

I could honestly give a shit what my top speed is, that's not the reason I saved a month's salary for this board. That being said, it would be ideal if it comfortably went up to 20mph for commuting and didn't struggle with quick acceleration. I can only hope these things will be addressed in future models (motion).

[dcosmos]

If we were all able to monitor our top speeds accurately, I believe we'd all be within 3 mph of eachother. True values would be useful because it would give both noobs and veterans a reference for assessment of their own hardware performance or their own achievement. For now, it's circus talk.

[depressedguy]

@dcosmos https://youtu.be/5FrA77wvcsg

[groovyruvy]

@ahxe45 @Hubbitron you nailed it. In this thread I posted a screenshot of the app showing I topped out at 27.8 mph, and @depressedguy showed a top speed of 44.81 km (27.84 mph). As they're currently configured the boards can't reach speeds this high. These artificially high speeds are a function of wheel slip- if during your ride the wheel loses traction and spins freely, that speed is then recorded as the high. If I'm going fast and then do a quick hard stop + reverse, I can trigger wheel slip and boost the top speed. Similarly when I'm charging grass hills I often get wheel slip right before I lose it, which also shows higher speeds. I've done rides where I made sure there was no wheel slip and on one downhill run I hit 18.5 mph, which was legitimate but also dicey as I was past pushback, I didn't have the advantage of the software self-leveling the board, and it was all pure balance. The board basically got away from me and I was able to hang on and ride it out to the flat. Once it slowed down, I was able to resume control as the software kicked back in.

@Hubbitron's comments about not being concerned with top speed, and wishing the board could reach 20mph without struggle, resonate with me. I feel confident that I could handle the board at 20+ mph if it was configured differently (say if pushback didn't kick in until 22 or 25 mph). But as the software is designed now, it limits speed, and that's very likely due to legal concerns. The faster these boards go, the more people will wipe out and get hurt, and FM may be trying to prevent lawsuits by limiting their liability by limiting top speed.

One thing I've come to appreciate from this forum is that older boards with 3034 software behave differently than newer boards that have a newer version of the software. I have 2 OWs, both with the older 3034 software. Their natural top speed is right around 14.8 mph. What I mean by that is they can both ride all day long at that speed without pushing back, and you have full control of the board with the software still in effect. You can juice it faster if you push, but the board behaves quite differently and feels totally different (and not as controllable). From what I've read, boards with the newer software seem to have a lower pre-pushback top speed, but allow for pushback to be passed by, unlocking higher top speeds. Even with that I don't think they're natural top speed is more than 15 mph.

Would be amazing if FM produced an Extreme version of the OW with a beefier motor, maybe a little bigger tire and higher top speed.

[depressedguy]

@ahxe45 You definitely have a point there. I feel that onewheel is definitely not meant to be ridden that fast and there is probably some zero error when it comes to the speed meter. Its also pretty dangerous to fight the pushback like that.

otherwise the board would shoot out from under you and you'd fall off the back. .

Yep, I remember having a Honda with a busted clutch when I was a teenager.
I picked up my buddy and took off leaving him falling down on his ass without me knowing it..

[Hubbitron]

@thegreck I will look up boosted board fails on youtube!

Prehaps the most famous one.

@sonny123 said in Post high speed here! OWheelbuddy app:

https://youtu.be/_I5w5jUboQU?t=246

Exactly! I actually like the way it eases into acceleration. It gives me a moment to get my bearings before acceleration really kicks in.

It's the same reason cars don't start out in fifth gear. You have to ease into your speed, or the tires just spin. Well, in a car that's what happens, on an electric skateboard, you see what happens in Casey Neistat's video.

[sonny123]

@thegreck

There's always the slow start option but most people looking for how fast they can hit 20 mph.
Most boards give the option of slower accleration.
I always liked Metroboard and they just upgraded their remote.

https://www.youtube.com/watch?v=Wcw6PB_eNTI

[thegreck]

@sonny123 Agree, options are always good! I'm all for having sliders on the app to be able to make adjustments on those types of things (acceleration, top speed, what speed pushback starts, etc).

[SeeTheInvisible]

@sonny123 @ahxe45 @groovyruvy @MichaelW You were all so right, I've just changed the speed calculation - I've not taken the wheel crushing into account when calculating speeds. Of course, it depends on rider's weight as well as your tire's pressure. Thank you very much for the effort to verify the actual speed's accuracy!

On the latest version, which has already been released for testing, the calculation is done with an average crushing value of 5 mm (about 0.2 inch) subtracted from the wheel's radius due to compression caused by the rider's weight.

So e.g. a speed of 30.2 kph (18.8 mph) equals a speed of 27.6 kph (17.1 mph) in the new version.

@kwatts you could also update your app's speed calculation in order to display proper speeds, just use this for e.g. kph -> topSpeedRpm * ((11.5-1.0)2.54PI/100000.0)*60.0

PS: as only the wheel's rotations per minute are stored in the app's database, it'll update your speed automatically when installing the new app.

[thegreck]

@SeeTheInvisible Well, it looks like I'm going to have to try even harder to kill myself after the update!

[ahxe45]

@SeeTheInvisible you are awesome man. I wish FM would take what suggestions people are saying on the forums and do something about it the same day. That's true dedication right there keep up the good work and like I said before I love your app I just noticed that speeds being posted seemed a little exaggerated.

[SeeTheInvisible]

@thegreck haha, yeah
@ahxe45 thx!

I had to think about my calculation all the time and I finally found out that I made a mistake: in the calculation I posted yesterday I subtracted 0.5 inches from the wheel radius instead of 0.5 cm.

New calculation for kph: speedRpm * (((11.5 * 2.54) - 1.0) * PI / 100000.0) * 60.0;

So with this revised calculation a speed of 30.2 kph (18.8 mph) equals a speed of 29.2 kph (18.1 mph) which still looks a bit high.

Could anyone of you also veryfiy the compression of the wheel?
How to do: put you board on a flat ground and measure the distance between the frame's upper edge and the ground - do this measurement where the axis of the wheel is located.

For the second measurement, you need someone who assists you in order to get precise values: Do the same with a rider on the board.

At the end, please subtract the second measurement from the first an tell me the difference and the weight of the rider which was on the board.

[thegreck]

@SeeTheInvisible This is getting really mathy! You'll also have to take into account the psi of the wheel, correct? People of all different weights ride at all kinds of different wheel pressures, from 12psi to 20psi.

[SeeTheInvisible]

@thegreck yes, I'll just use
the average value

[thegreck]

I guess this is probably what it looks like to ride at around 20+ ... this guy is flying!

[tr6]

19.5 quickly followed by a crash; no pads no helmet no injury!! Now I'm scared, haven't gone over 15 since....I think that's going to b my record until I get a +...

[groovyruvy]

@tr6 you're down to 8 lives left . . . . . :)

[MichaelW]

My high speed is 19.2. Also ended with me skating on the front end of the board and falling. I had full pads on Thank god! @tr6

[badcheese]

With no load, the motor can spin fast enough to report about 35 mph in the apps. Ideal conditions for riding at that speed are when resistive forces (aerodynamic drag + rolling resistance) are in equilibrium with forward force due to gravity, resulting in no load on motor except inverse pendulum adjustments required to keep rider balanced.

In other words, a rider with perfect skill on the perfect slope would have a theoretical top speed near 35 mph. Here's my stab at calculating the perfect slope:

https://drive.google.com/file/d/0B_JYK-b6rIj7RF9GTURhRXRESzg/view?usp=drivesdk

When OWheelBuddy includes Android users on the leaderboard, I'll strap on some pads and see how close to 35 mph I can reach with my imperfect balance.

[Hazeey]

Just curious what the advantage is of paying for the OW BUDDY over using the free powheel app? Does the buddy hold lifetime mileage or something different? That's the only thing that I'd like to have, thanks

[cytoe]

Lifetime mileage is stored on the board (both apps show this). The free app is good, but owbuddy auto connects and connects faster which is reason enough to buy:)

[Hazeey]

@cytoe that's what I thought but swear last time the app only showed my trip total while app was active....I'll have to look again. Thanks

[dalisdair]

@Hazeey

I read somewhere in the forum that riding until it's completely dead can reset the total mileage back to zero, but that hasn't been my experience.

[dalisdair]

@depressedguy

Nice OneWheel track.

[dalisdair]

@sonny123

I don't know how a bicycle speedometer works. Wouldn't accuracy depend on being a particular distance from the axle?

[sonny123]

@dalisdair

Not as much as the size of the tire.
I think the minimum has to be 16"
So I was off few percentage points on OW

[Hazeey]

@dalisdair I have done that once or twice so maybe that happened. Given its been 34-40 degrees max so far when riding in WI since I got it 3 weeks ago I've had to reboot to get every bit of 2.5 mi. Cant wait to actually ride 6 miles per charge!
I know it showed when I first used the powheel but not last few times when I was looking. Guess I'll have to try and not sap it every time I ride and see if it holds. Thanks for sharing!
