How mod is too mod?

[NotSure]

Perhaps I should explain. What are the technical limits of modding an XR? Range is easily added externally, but how about performance? Do battery mods actually improve the capability of a stock XR and if so, by how much? It should be demonstrable if there is a benefit. I imagine the same conclusion could be made for the GT in the future. Could one mod their XR into a GT? I imagine there are limits to the hardware.

@NotSure -- With a deep reservoir of EGO batteries to draw power from, my Plus seems equal to an XR in speed -- I am daily cruising in the low twenties. Add to that the Kiil Suspension with my choice of tires, and in my opinion my Plus exceeds the projected performance a GT.

[b0ardski]

4 yrs from now the gt will be like the xr is now. you can mod it to death the xr will never be 74 volts

[NotSure]

@blkwalnutgrwr wow really? 20+ mph? mind if i ask how much u weigh? I'm about 190.

I have yet to take my XR beyond 18, but i'm just not eager to push it too hard. I wish they had detailed spec charts available.

From what I can tell the stock XR can do 1.8 hp for as long as the battery can delivery it, right? 20A continuous. cbxr claims 30a continuous which is 1800 watts. that's 30% more power correct?

if the stock controller can handle 30A continuous without failing, then that's 2.4hp, right? a significant upgrade by any definition..

[NotSure]

@b0ardski stunt pack by chi boasts 45A continuous discharge. that's 3.75-ish hp! but i admit i have no idea how the onewheel hardware actually manages that potential power.

[blkwalnutgrwr]

@NotSure -- About 160 with another ten lbs of clothing, doo-dads, jacket and gear. Paved Rails-to-Trails Greenway. Pushback is something I feel when I slow way down -- and it lets off!

im not sure i understand.

[blkwalnutgrwr]

@NotSure -- I ride pushback so constantly that I do not notice it at all... until I slow down. Then there is a feel-able, marked relaxation of the nose at what seems to me like a very slow speed... probably about 15 or 16mph.

[NotSure]

@blkwalnutgrwr oh ok i get it! thx for clarifying. that's interesting. i just ordered some flight fins and i'm considering just modding the shit outta my xr n seeing what happens with the GT.

[NotSure]

@blkwalnutgrwr said in How mod is too mod?:

what does the board feel like at 20 for you? As a comparison, when i get up towards the top end i spend more energy attempting to "hold" the board under me in an effort to aid the board's ability to keep me upright. Perhaps that's not necessary on the paved surfaces i normally ride on, but I feel very solid on the board while doing so, especially while above 16 mph or on highly variable terrain. Problem is I haven't figured out where the horizon is lol. Not eager to find it tbh lol.

I did some googling n it seems the 5.0ah ego has a max continuous discharge rating of 40A. The 7.5Ah can do 60A! If the stock xr hardware can handle 60A, even for small lengths of time, that's 4.75 hp! that's a cement mixer!

[blkwalnutgrwr]

@NotSure -- And these days I have been running two EGO batteries, sometimes two 10ah in parallel, although more often a 10ah and a 5ah, and sometimes a 10ah and a 7.5 ah. The power feels wonderful!

[NotSure]

@blkwalnutgrwr well clearly the controller limits that power. ur def not running 80A thru ur hardware everywhere you go right? this i clearly where my knowledge of electrical engineering breaks down. I would imagine it's a temperature issue beyond a certain current. would need to start actively cooling the hardware at some point. i dunno. @Lia why doesn't ur XR fly yet?

[Lia]

@NotSure wonder what sort of wingspan I’d need to get 13kg airborne lol.

Regarding current. For the most part current is drawn, not delivered. The motor is pulling all it needs so even if you provide a higher amperage sources it won’t use it. The motor windings have a fixed resistance being the wire making the coils.

Voltage = Current x Resistance
Aka
Current = Voltage / Resistance

As resistance is fixed only changing the voltage would change the current.
However since Power = Current x Voltage you’ll always end up with the same power no matter if you tweak either current or voltage since they inversely change the other.

Realistically if you want more power you need to change the resistance which means a different motor.

That said increasing the available current will be useful since you offset the performance sag you otherwise get when reaching the limits of the existing batteries built in.

I personally notice pushback more with my external pack although I chalk this up to a diminished voltage sag allowing the pushback to be more pronounced.

[NotSure]

@Lia well if that aint definitive! so much for that myth. so has anyone replaced their motors lately?

[Lia]

@NotSure The 750w motor FM use might still be capable of more. Motors are a bit of dark magic that I have yet to understand. I need some electrical wizard to sit me down and explain it >.>

The wattage rating on the motors seems to be some sort of estimated power rating that I have yet to find consensus on how they measure this. For instance my old eBike's 250w motor to this day manages to let me put over 500w through it if I just change the controller and battery to allow that to be delivered.

So that being said I assume that 750w motor on the Onewheels is capable of way more that 750w if it is given the ability to draw it. Leaving us looking at the ESC that manages power delivery.

so here we are... full circle... back to vesc. So to clarify for those reading this looking for answers: there are no known means of upgrading a onewheel XR into a GT bc there are considerable technical hurdles to doing so. That's not to say it's genuinely impossible, just that it's possibly very difficult. Reddit will be so displeased lol.

So, anyone try a floatwheel?

Nope. Why? Because of >this thingy< ?

so considering the implausibility of "simply" boosting the supply of current, has anyone "simply" attempted to amplify the voltage of the existing esc? Sorta like using the esc to control another esc. Does that make sense?

[NotSure]

@Sirgu i don't understand. what is it difficult or something?

[Lia]

@NotSure No idea, I'm only on reddit and don't hear much about it. At most I see people replacing the controller with a VESC and calling it quits.

That link from Sirgu is a good find, you can attach the floatwheel hub/wheel assembly to a stock board using that adapter so you could in theory put a higher wattage motor on it.

[NotSure]

Oh i get it. So ppl have tried apparently... So [gulp] where are they? lol.

@NotSure 88 mph with 1.2 gigawatt battery should be possible

[NotSure]

@b0ardski said in How mod is too mod?:

@NotSure 88 mph with 1.2 gigawatt battery should be possible

that's impractical. as @Lia explained, it doesn't matter how many gigawatt hours we have...

maybe we can decrease resistance instead? cool it down a bit maybe?

[Lia]

@NotSure I dunno, 1.2 gigawatts might be enough...

If we can hit 88mph we could maybe even stop the hardware lockdowns~!

I have yet to feel pushback on my XR. I purposely rode it up to 17 mph the other day and didn't feel anything. I slowed down of course and didn't go further. I normally ride around 14/15 mph most of the time. I'm one of the few that likes the pushback of the pint. Without even paying attention the pint gets my attention because the pushback is so strong. I don't have to think, at pushback I know I'm at 14 mph. I use it as a speed gauge.

I go above 18 only for brief moments when im carving hilly roads. yeah XR pushback is super subtle. I don't prefer stronger pushback as implemented in the Pint. Maybe the px is better than og on that. og is like hitting a wall compared to xr.

I prefer the pint board design to the xr. xr is rather wide making it more difficult to dynamically torque the board angle but i do still have the vega on there.

tire recommendations anyone? currently 75% street, >20% trail, <5% beach (soft inclined sand)

[Swinefeaster]

@NotSure here's a good video about the px, apparently push back is also just as strong on the px as on the p. https://www.youtube.com/watch?v=CmTqpVQjtl8&list=LL&index=1

i recently felt really strong pushback on my xr for the first time because i drained it down to almost zero battery lol. it was weird, like hello, i didn't know you did that.

tire? ff hoosier t2 all the way baby. it's nice and carvy, sticky as hell, and pretty quiet. rides street real nice for a treaded. i'm on my second one, lost all my treads after about 2000 miles, so something to consider if that's not enough life for you.

Do u know of another tire that might be the mid point between max durability and the t2 d30a?

[Swinefeaster]

i've only tried vega and t2 on the xr, so no personal experience to be shared.
but here is a vomit of info for you:

Same, on my second Hoosier T2 as well, but my first one made it over 4000 miles (90/10% paved/trail)! I've been riding treaded since my +, mainly for the traction as it handles wet grass and leaves as well as patches of mud way better than a smooth tire. I've had a Hoosier v1, a Burris, then the 2 Hoosier T2s. One other thing I've noticed with treaded tires is they almost never pick up leaves into the fender well, which is why I put magnetic fenders on my boards, but no longer really need to take them off very often.

On pushback, I've only barely felt it on my + and my XR around 19 mph, though I have felt the low battery major pushback. I ride around 16/17 mph with an occasional spike up to 19. I have the app on my watch, so I can check my speed anytime. I gave up on @Future-Motion ever adding a customizable speed alert to the app (no matter how many times people have asked for it), so that's been my solution to preventing a second nosedive at 21 mph!

[NotSure]

@OneDan said in How mod is too mod?:

nosedive at 21 mph!

yeah not eager for that. i'm just looking for that same little bit of traction on wet surfaces. mag fender seems useful too.
