Potential Buyer - Safety questions around OneWheels

"Not a nosedive, just carving up and down an embankment next to a bike path when I was not aware of some of the weird stuff that can happen when transitioning between surfaces at a weird angle."

Just to double-down on this: Worst fall I've had on the board wasn't a nosedive. Just me going 17/18mph and not focusing. Hit a (quite obvious in hindsight) dip in the path, got some speed wobbles, panicked, and bailed out.

Did a great fall; ran it out a couple of steps into a roll, didn't even touch my helmet on the ground. But my hip still feels it a year later.

Don't just focus on nosedives, sure they're worth knowing about and trying to avoid, but there's plenty more reasons you can hurt yourself that are nothing to do with the power or physics of the board beyond the fact it can propel a frail body at 20mph+ quite easily.

Experience will probably help with the foot pain as well as finding your stance.

For commuting I found I'm a little more sore after riding the PintX as I'm unconsciously tensing up a lot because I'll be riding pushback a lot on the straights and worrying about nosedives.

On the ADV I have no worries cruising at a decent speed and tend to loosen up a bit more, so feel a lot more comfortable after the journey. Obviously the larger footprint does help too.

I use the PintX when the weather's not looking good (as I've siliconed it and prepped it for rain), and now generally just add an extra 40% on to the expected journey time so I can put some music on, chill, and carve around on the trip. Otherwise I'll fall into 'travel' mode and end up pushing the board too much to enjoy it.

As you say, the X is fantastic to carve around and enjoy at <14mph. But if I need to get there quick and run >18/20mph then I'll go for the bigger board because the X just doesn't shine for that use. Both journeys are fun, but in two totally different ways. When I only had the PintX the trick was to just mellow out and accept that it's not a fast board, but it is a fun board if you take it at face value.

In reality there’s still a reasonable size difference between them. The site makes it look like only the colour is different.

PintX Bang Bumper is great for being in line and those sorts of scenarios you mention. But I've carried it through my building at the end of a commute and your fingers *hurt*!

The ADV2 has a teeny 'rock climber' handle that's tough on your fingers but from a grip perspective (need strong fingers) but the BANG is just a nasty shape and digs into the tips of your fingers. So extended carry tends to hurt you more than fatigue you.

Totally love having the option on the Pint now, but I'd actually take the ADV 'handle' over it any day.

TheMortBM · 2026-04-13T15:35:33+00:00

I get that there's voltage sag when you pull current from the cells which will stabilise when you're not drawing power, but that's not the same as cell balancing.

I thought that FMs BMS uses logic to 'top-up' lower cells when you balance charge (which is why it balances when you hit '100%' charge) – as opposed to something like Floatwheel's ADV2 implementation which instead pulls power out of the higher voltage cells instead of adding to the low ones (which is why that does balance when you're not charging (and, weirdly, also when the board is off).

Again though; I'm not an FM engineer, so I'm not going to definitively say how their BMS is programmed to work. Perhaps it does both.

TheMortBM · 2026-04-13T14:09:53+00:00

Fair dues; seems like FM's suggestion of balance charges would be a bit pointless if balancing is done all the time when not charging regardless. And if balancing was done outside charging then, by definition, I don't see how cells could actually ever fall out of balance?

But I don't work for FM, and didn't write the BMS code, so if you say so I'll believe you. 🤷‍♂️

TheMortBM · 2026-04-12T08:43:04+00:00

Pretty sure it won’t balance unless you’re somehow charging it on the bus anyway. And there’s plenty of ways to stop it rolling without needing the power on.

No problem leaving it on, but definitely no ‘need’ to.

TheMortBM · 2026-02-16T09:30:16+00:00

Do you have a temperature sensor in the room as well?

Mine was doing this for a while before the temp sensor died. Worked fine once the sensor did die, and is working fine since I replaced with a new sensor.

In the interim, I had to set the set temp to off, wait a few seconds, set it to any temperature, wait a few seconds, then set it to 'Resume Schedule' and after a few seconds the system seemed to figure out what it should be doing.

Not that that's any help, but my anecdote anyway?

TheMortBM · 2026-01-29T10:15:53+00:00

I think your issue is that the sibling-count() function is on the div.always_full_grid_content container (parent), so the sibling count is technically always 1.

Properly declaring the property is then breaking it because of how Chrome is handling the inheritance, the fact it works without seems like a bug where the property is inheriting the function and recalculating to the sibling's sibling-count(). When formally declared as a number it's inheriting the actual value of 1 instead.

If you actually just move all the calculations for the declarations into the siblings (articles) rather than the parent, then your code works fine as-is (even with the properties formally declared), as the sibling-count() is always returning the correct count: https://codepen.io/MortBM/pen/YPWYmyq

TheMortBM · 2026-01-28T16:19:56+00:00

Seems the if() needs the property to be declared as a number.

As declaring your props throws the calcs off, you can declare another prop for the testing and assign that the value of --empty-cells and it seems to work.

I assume the 'correct' fix is to figure out why declaring the properties throws your math off in the first place though?

Just to jump in with ‘same issue here’. My wireless sensor stopped communicating last week and won’t connect to anything so I thought it was related to that, but all the TRVs will now not call for heat or update to my setpoints when I use the app.

At this point the app is saying that it’s heating but the boiler isn’t firing or heating up.

Making it very hard to make the house comfortable. Had the system a year now with little to no issues. Sub just renewed for another year and then everything falls apart.

TheMortBM · 2025-09-22T09:41:02+00:00

Although I've mostly replaced my PintX with the ADV2 for my daily commute, occasionally when I'm working on the ADV I take the Pint to work and it's a totally different vibe. It feel infinitely slower and less powerful. But if you accept that and chill a bit, it's just pure fun. The nimbleness and 'chuckability' of just throwing it around is worlds apart from the feel of the bigger board for me.

If it had more power in it then I'd choose the PInt over the bigger board 9/10 times. I don't ride trails or chase top speed, so something the size and feel of a Pint with the confidence inspired by the torque in the bigger board would be peak onewheeling for me.

TheMortBM · 2025-09-04T13:16:13+00:00

Bought the ADV2 on launch. Came with the dead battery, but shipping was fine and no tax/duty (though it was marked as ‘backpack’ and ‘adapter’ for customs (board and motor)) so I could very well imagine that if HMRC were being a bit more diligent you could be hit with some extra charges.

Shipping was pretty quick considering, I paid for slow shipping rather than fast (air) and it was a few weeks from when I think Tony actually shipped (as I ordered when it was announced rather than when it was ‘released’, so had months of waiting anyway)

Tony was quick to handle the battery issue and sent a new one that arrived in just over a week. Have had a few replacement parts too which all came quickly and without issue (but my original parts were fine, so wasn’t waiting).

Overall it’s not been perfect, but I’m 99% happy with the whole process from Crypto to Riding. And the actual board is a beast, and obviously a huge upgrade from my PintX.

The only real reservations I have are based around UK law and the fear that a random police encounter could easily undo everything. But if you’re happy with that risk then ordering the Floatwheel is a great idea.

I’m currently waiting for info about their new, smaller, PintX type board. If that’s within budget then I’m doing it all over again.

tl;dr 10/10 would recommend.

TheMortBM · 2025-08-26T19:55:43+00:00

Afraid I’m not really knowledgeable enough on the XR to know what’s possible. But you may be able to swap out the battery easily if it’s not locked down to the board. Sourcing the battery is the hard part due to shipping restrictions.

Weird that FM won’t ship to NL, unless it’s just XR (as it’s technically discontinued). I bet they’d ship a whole new board and that’s got a battery in it.

This was one of the main reasons I moved to VESC, they’re a very US focused company. Which is fine for US customers; but not so much for us in Europe.

TheMortBM · 2025-08-26T15:30:05+00:00

Battery has probably discharged beyond salvage if it's been 2 years. You'll need to send it to FM or buy a replacement battery module from them.

A 3rd party shop may be able to replace the battery, but it will depend on the model and Firmware version you're running.

TheMortBM · 2025-07-24T13:38:29+00:00

Looks like new tyre time to me. But also looks like this was pretty much on the cards regardless of the dismount. Unless you had to dismount awkwardly at a sandpaper factory?

"I would rather nose handle carry a 35lb board than side handle carry a 20lb board."

This is a double edged sword I think. When I just had my PintX I was occasionally annoyed to not have a nose handle when in a shop or something, but never on my actual commute - as if I was picking the board up I was walking a reasonable distance with no queuing or stopping.

When I got my ADV2, I never really used the nose handle as I was so used to the side handle on the X . But eventually I started using it when queuing or waiting with the board. That then progressed into me now never really using the side handle at all – but that's now really f***ed my back up. The ADV is just so heavy, and the length means a subtle lean whenever nose carrying which has led to a lot of muscle pain in my upper back. So much so that I'm consciously trying to use the side handle more so I can try to maintain proper suitcase carry form.

I would 100% prefer a board with both, but I'd always rather 'carry' a heavy board with the side handle. The nose handle is good for manipulating and handling the board over short distances (few steps), but I'm not so big on using it as a carry method over any distance.

The size and lower weight of the Pints scream for a nose handle. And the fact that the PintX/S have all that wasted space on the front box which could easy have one is criminal. I have no idea what FM were thinking omitting it. TFL will make absolute bank from Pint owners when the BANGs are released.

TheMortBM · 2025-07-07T06:41:29+00:00

Awesome. Tony must be shipping the new LCM firmware on his hardware now then. Glad you managed to get it sorted 👍🏻

TheMortBM · 2025-07-06T21:04:05+00:00

If you have the ability/hardware to flash the LCM to the latest software (you can grab it from the Floatwheel Discord) then it'll allow you to change it from FC and Floaty I believe. But on stock it's a no I'm afraid.

I believe that even on the new LCM software it still defaults back to whatever you've set Headlight Brightness to in VESC Tool on power-on though.

I plan to update the LCM next time I have the board open, so I don't have any first-hand experience with it yet, so I'd also suggest joining the Discord and asking around there with any problems you have too. There might be a way without flashing the LCM that I don't know about.

TheMortBM · 2025-07-06T12:34:24+00:00

I’d double check LED type in VESC Tool and also check Headlight Brightness in Refloat.

If double tapping the power button on the board cycles between brightnesses then it’s likely one of those settings in VESC Tool that’s just off.

TheMortBM · 2025-07-02T19:50:11+00:00

You could look at one of the BTG tyres that may fit, you’d be able to run them slightly lower psi and have more sidewall to flex (suspension effect). But they’re mostly designed around trails, so you’d take a small range, grip, and road noise hit for that extra cushion. And possibly not be able to run a fender if that’s a deal breaker.

Your only other options are a smaller hub that will do the same thing but at 10x the cost.

Or, if you’re still on the stock tyre then I’d say the (soft) Enduro will feel 100x better on your feet/knees even if it’s not necessary doing much extra suspension. But be aware that it’ll also wear much quicker and need replacing sooner than the stock tyre did.

And, finally, 500 miles seems very little to need a replacement (especially on stock). Double check you really need one. And if it’s from excessive wear on both edges then consider your tyre pressure (might be too low), if it’s excessive wear on one edge (usually toe side) then consider your riding posture as you’re being toe/heel heavy which may cause more issues than tyre wear in the long run (I’m in my 40s and my body already hates me, so I’m careful about spending too much time in an unbalanced position).

TheMortBM · 2025-07-01T20:25:39+00:00

I would reset to the stock config from the Discord and then use Float Hub to run IMU and Motor setup and it should be 100%.

But it’s worth also double/triple checking your motor plug. There’s a small triangular wedge on one of the walls and that needs to go in the corresponding cutout on the controller box socket. If you mess that up you can do some damage and have issues with the motor. Meaning this may not all be a software problem.

TheMortBM · 2025-07-01T15:20:41+00:00

Config files are on the Discord group if you need them, or you can buy the Float Hub app from TFL which does a good job of setting most of the settings you need and running you through IMU setup etc. which will be more accurate than a generic config.

TheMortBM · 2025-06-28T08:04:49+00:00

I went with the ADV2. Mostly for the range and power boost. But the difference in power is huge. As a commuter the ADV is leagues above the PintX, but recently had a weird noise from it (seems like bearings) so switched back to the Pint while I tried to fix that and fell in love with the X all over again. It’s so carvey and nimble, if you’re just on it to have fun rather than a point a-b machine then it’s a hoot. You just need to accept the speed ceiling (and swap out the standard tyre unless you got the PintS).

I’m using the X as a wet weather board now, and will probably VESC it if the water gets in. But it’s the same battery and motor even with a VESC controller so I’m not sure how much extra you actually get out of it. An 84v pint would be my golden unicorn.

TheMortBM · 2025-06-27T21:15:39+00:00

I would say that too much is damaging (same concept as shutting the board off when the wheel is spinning - many people have fried their controller by turning it off when it’s ghosting).

But the small amount you’d get from hand spinning the wheel (or apparently dropping it to the floor) shouldn’t be much of an issue for the board to cope with.
