Alright, I didn't mean to say I could not at all drive straight straight with the V8. Just, that I feel quite a bit of instability when driving straight which shows in particular when passing longitudinal grooves. I would say that a 14" Gotway MCM2s doesn't feel that much different in terms of stability, but after all it is a 14" and it feels like I can more easily adjust to wobbles on it. A 16" IPS with a Chao Yang tire of the same width feels considerably more stable on straights but much less agile in producing small curves. Like you, I am not even close to be tempted to change tire (yet). On the other hand, I found removing the side panel to access the battery relatively smooth, contrary to what had been said by others.

Tim Koffler Posted January 9, 2017 Share Posted January 9, 2017 I've been riding the V8 for over a month now and am totally in love with it. It is the smoothest, most balanced and responsive, incredibly stable riding wheel I have been on. I own 4 other wheels, and generally when my tire pressure is lower I experience wobbles and slight delays in motion...when it's 45/50 PSI + it's squirely and over responsive. I would say to the original issue posted that it is probably a tire pressure thing or rider not in sync with his wheel, yet. 1 Quote Link to comment Share on other sites More sharing options...

I know this from one of my wheels-KS18- also....And: I have it much more on my KS18 as on the the V3. The reason for me is the tyre...i can not describe it in english exactly, but the Profil on the V18 has a 1cm wide roundgoing rubber exact in the tyre middle with rubbergrooves to the left and right. When i have the pressure high, this grooves have the tendancy to get a hang to the straight rims from Stones of sidewalks....and if you ride exactly beside this rim , the contact of tyregroove and rim can really push you a bit to one side! On the V3 the rubber Profile is not this Kind, so i did not get this "hanging on Stone rims" Quote Link to comment Share on other sites More sharing options...
Popular Post nomad Posted January 10, 2017 Popular Post Share Posted January 10, 2017 Yes it's the tire! I've read some are saying the V8 rides almost as agile as the V5 you'll hardly notice you're riding the 16".. The tire is the reason for that. If you use it as a toy, keep the stock tire it's easier to turn with, play around and do tricks. But if you're going to use it mainly for commuting then I would trade off some agility for superior directional stability! I'm sure my V5F+ is more stable than a V8 with that Kenda tire. Changing the tire on my V5F+ did make it noticeably less agile, but it really solved this issue. The old tire was snapping into all kinds of groves, cracks and even passing over painted lines on the ground I was constantly 'railed'. Cobblestones were an uncomfortable bumpy wobbly mess but now it's totally fine, night and day difference! Also the Inmotion wheels are thin with high pedals making the effect worse. My V5F+ handling transformed so it behaves closer to the Msuper v3 now than to a stock V5, yes still big difference to the 18", but indeed closer feel to Msuper than to the stock 14" tire believe it or not, that's the kind of difference my new tire makes. Also I never pump it to 60-70 psi like I did with the old tire because it's already as hard at 45 psi, it's rigid and at the same time more comfortable, because it also has much better impact absorption too! 7 Quote Link to comment Share on other sites More sharing options...

The tire will make a significant difference on directional stability for sure, the Kenda is more of a slick type great for smooth surfaces and very agile for tight turning. But the Inmotion wheels won't be as stable as a thick wheel for example the ACM 1300Wh that is 'grabbed' between the legs. The thin body allows more play side to side between the legs.. Plus your stance is narrower, think circus act balancing on a board on a stretched line in the air. With a wider stance balance will be more stable than if you put your feet together. So it's a combination of tire type, narrow stance, thin shell and high mounted pedals. Higher pedals are less stable than low pedals because the chassis pivots more higher up, than it does closer to the bottom. 4 Quote Link to comment Share on other sites More sharing options...

Popular Post Jason McNeil Posted January 10, 2017 Popular Post Share Posted January 10, 2017 (edited) In a recent communication to Inmotion, mentioned [again] that while majority of the feedback with the V8 is overwhelming positive, on the very simple matter in the choice of tire, the consensus of informed opinion is that there are better choices available. As some others have pointed out, going to a lower tire pressure [35-45 psi] somewhat mitigates the irregular tread pattern. This message doesn't seem to be getting through. I'll try to get a suggestions email address for Inmotion owners to get their voices heard. We've got a batch of Chaoyangs on the way, they're 2.125" width, so I'll need to test to make sure they fit the width. 16" Tires: the general feedback from experienced Customers who have owned another Wheel has said they're not very happy with the stock tire that comes with the V8. Please note the difference between the tire on the Ninebot One (also a Kenda) and the V8. The problem is that the tread is too narrow which distorts the ride -----As we know,our current 16'' tires also be used on Ninebot and KS product,but just for different batch production.Actually,that is from the same supplier. Except US,there thousands V8 have been sold out,but have no any quality and such distort riding feedback,frankly.

Mono Posted August 5, 2017 Author Share Posted August 5, 2017 Indeed, I was riding for a week or so on 2 bar tire pressure and the wobble is practically gone. Tough call, as I don't want to risk my rim or tube either. Quote Link to comment Share on other sites More sharing options...
LanghamP Posted August 10, 2017 Share Posted August 10, 2017 One big reason I love my little KS14c is because its relative indifference to tire pressure. From between 45 to 60 the wheel feels neutral at all lean angles. Not so with my V5F+. I have always had handling problems, and it often seems impossibly hard to ride. Other people rave about the handling of the V5F yet to me the wheel is a very difficult wheel to ride. Last weekend I took it out to a park, with my air pump, and tried a lot of different air pressures. I discovered the air pressure has to be within 52-55 PSI for it to be neutral with me. That's 3 PSI difference, an itty bitty band of good handling surrounded by a gnarly ocean of bad handling. For people who weigh less than 200 pounds, the V5F is probably forgiving but for those approaching and above 200 then you're looking at a very narrow range of tire pressure.

Stan Onymous Posted August 17, 2017 Share Posted August 17, 2017 I bought a 2" Haro tire. Much better tread pattern. I havent tried it yet and am away from home, but it's more like a 22" monster tire as far as tread goes Quote Link to comment Share on other sites More sharing options...
Stan Onymous Posted September 7, 2017 Share Posted September 7, 2017 I have a 2" Haro tire 16" diameter, and the treads are more logitudinal running with tread arrows smaller than others. It was on Amazon. Very reasonable at $13 and its shape looks like it would minimize that zigzag pattern of the Kenda. On a separate note, sometimes when I get the wobbles its just poor foot placement on my part. On the V8 I switch where my feet stand depending on terrain, slope, and speed. I still think the tire contributes to this phenomenon because it has happened on my KS14C while going down hill and it also has the dreaded treaded Kenda. 1 Quote Link to comment Share on other sites More sharing options...
DavidM Posted September 16, 2017 Share Posted September 16, 2017 Hello all I have the same feeling moving from a Ninebot to the V8 and assumed it was also because the pedals are much higher: the center of gravity is higher. I got used to it with time! 1 Quote Link to comment Share on other sites More sharing options...
Mono Posted September 19, 2018 Author Share Posted September 19, 2018 On 1/7/2017 at 1:33 AM, Mono said: its directional instability drives me nuts. Driving this wheel straight along longitudinal grooves is more challenging than making small backward circles (which is, admittedly, with this wheel surprisingly easy). I didn't have any crash, but the wobbles are crazy scary and make precise steering super difficult. What is your experience? I suspect the main or even sole reason might be the Kenda tire? I am now using a different Kenda tyre (see link) and the wobbles have virtually disappeared. 1 Quote Link to comment Share on other sites More sharing options...

I have the Kenda k1039 on my KS16S; it has awful directional stability for the first hundred or so miles, especially inflated to 62 psi, but afterwards it becomes more directionally stable until it becomes too difficult to turn. I bought mine on Amazon USA. Or, rather, two of them, for $20 each. Yes, I have three of these exact same Kenda and one innertube with 8 patches in it. 1 Quote Link to comment Share on other sites More sharing options...

Thewheelone Posted January 15, 2020 Share Posted January 15, 2020 So...Did a few things that seem to have mitigated the wobbling by big amount (enough to be fun to ride again)...and I thought I’d share. Not entirely sure which action or combination of made the most impact but here they are. 1. Re-installed the inner tube with the valve pointing up 2. Filled air to 50 psi (on stock tire, at least) 3. Placed feet further apart when riding (and possibly even a bit further back than center) Let me know if it works for anyone else! Quote Link to comment Share on other sites More sharing options...

I think the only solution for users with the narrow and quite slick Kenda (the 1,95" tyre) is simply to change it. Impossible to avoid some wobbling at fast speed and almost impossible to ride it in a straight line for long. Even more if the urban streets are damaged with holes and cracks.
