novazeus Posted March 25, 2018 Author Share Posted March 25, 2018 charged the wobbler up and rode it a bit. the wobble is still there but it does seem to get better and worse during the ride. it’s almost like the axle nut could be loose? idk. but while i was riding and thinking what a pain it was to ride that new s1 in learner mode, maybe it’s because i grew up at a golf course with degenerate gamblers and carnies, how fun it would be to go to a parking lot after hours and set up some cones and have s1 races. u could do it in learner mode which is really slow. riding that tiltback.

Much be worth a try... i’ll give that a try. it was really bad at one point today, like dangerously bad. i’m starting to think it’s the tire. i may play with the pressures, like pump it up to 60 or 65 psi. still have no idea why the s1’s freewheel so smooth and silent spinning them by hand and the s2 has much more resistance and noise. i use to spin my inline skates by hand to make sure the bearings were in top shape. almost tempted to buy another s2 if i could find a steal on one.

Smoother Posted March 27, 2018 Share Posted March 27, 2018 (edited) Well, those vids are quite interesting. I'm not sure what conclusion to draw except there is movement in the tires, and that's not as good as no movement. When I pick up my wheels they shake as they rotate too. I suspect everyone's do/does to some extent. I think that balancing video might help some of us, or at least eliminate the shake. I don't think balancing will stop the central rain grove of those tires, or the flat central rib on most tires, from wandering left to right as the wheel turns. Whenever the contact patch of the tire is to the side of the center, there is a side load which will force the wheel to one side. The more the deviation, the higher the force. Move this force rapidly from one side of center to the other and back again, and there is a chance that it could be felt by the rider. ALL JUST CONJECTURE, of course.

It's definitely odd that it has just started... The balancing aspect is very interesting though - it's something I'm playing with at the moment (time permitting). My Lhotz needs about 40gm to reduce the wobble - once l work out the final numbers, I'll make a video explaining what I find. Quote Link to comment Share on other sites More sharing options...

GoinPostal Posted March 29, 2018 Share Posted March 29, 2018 On 3/22/2018 at 9:58 AM, novazeus said: so a couple days ago i decided to give my wheels a little exercise. started with the 9bot1e+, then switched to 9bot1s2 and i noticed wobbling. since beginning to learn, i never had wobbles, except for a very short distance i attributed to my feet being to far back on the pedals and once i repositioned my feet, they went away. so i checked the tire pressure and it was down to like 46 psi, so i pumped it back up to 54psi. still got wobbles. so i thought, maybe this is the leg tiredness people have talked about because i hadn’t been on the wheels everyday. then i took the 9bot1s1 out, and no wobbles. then the ks-16s, no wobbles. just the 9bot1s2. my feet are positioned exactly the same way as the s1. if it were leg tiredness, i would think this would happen with the other wheels, especially the s1 which is identical except for speed and range reduction. i’ve noticed spinning the wheel by hand, the s2 is different then the s1. the s2 doesn’t have that may miles on it and has been lightly used but i suppose something like an axle bolt(i have no idea what the guts look like) could have loosened. these wobbles start around ten mph. very noticeable. not fun to ride. When I ride every day.. no wobbles. Ever. If I don’t ride for 3 weeks.. guaranteed wobbles until my legs are back in peak EUC condition. 1 Quote Link to comment Share on other sites More sharing options...

novazeus Posted March 30, 2018 Author Share Posted March 30, 2018 (edited) and i might miss a day or two but generally i ride daily on an assortment of wheels from 14” to 18” and inbetween. Edited March 30, 2018 by novazeus Quote Link to comment Share on other sites More sharing options...
novazeus Posted April 4, 2018 Author Share Posted April 4, 2018 i thought i had it figured out. running high pressure 60psi in the tire. but now i’m thing it wasn’t that at all, i may have ridden the wheel backwards. here’s two videos from today a little while ago. first one in the tire direction way, power button in the front. second one moments later in reverse. 1 Quote Link to comment Share on other sites More sharing options...

I think I know why you are wobbling. Your feet are placed too much towards the front on the pedals . Move your feet back by a couple of inches. You must have changed your foot position at some point and got used to it. If this doesn’t work let someone else ride your wheel and compare notes Quote Link to comment Share on other sites More sharing options...

If this doesn’t work let someone else ride your wheel and compare notes ha, that’s funny, let someone else ride ur wheel. if i moved my feet back a couple of inches, my heels would be on the pedals. no that’s not it. if u look at the two videos i just posted, my feet are in the same position. i own and ride 3 of these 14” ninebots, 2 s1’s and one s2. if u have ever seen one, u know they are identical, except the s1’s are detuned. the s2 is the only one after close to thirty miles on it, started wobbling. so i thought, i’ll calibrate it and see if that makes a difference, nope. riding it opposite direction of the proper tire rotation cures it though. look at the videos. the first one is the proper direction and the wobbling is apparent, second video is seconds later in the reverse direction, no wobbles. it’s either axle nut, tire or motor.

Are you saying the rear of your feet do not project beyond the pedal at all? They should somewhat...It’s great if you pinpointed the cause of the wobbles. I just know that in some wheels, putting your feet too much forward will create similar wobbles. Perhaps, in your case it’s different Edited April 4, 2018 by Cloud Quote Link to comment Share on other sites More sharing options...
novazeus Posted April 4, 2018 Author Share Posted April 4, 2018 no my heels hang off the rear of the pedals on all 6 of my euc’s. only one started wobbling at thirty miles on the odometer. the other 5 do not. i never had “beginner” wobbles. thought i had a theory on that because advice given on this forum for newbies is lower tire pressure makes it easier to learn. i learned with my tire pressures on all of my wheels higher than the max pressure listed on the sidewalls. when i increased the tire pressure from 47 psi, some had leaked out, to 60 psi, the wobbles went away, but now i’m thinking i might have been riding it backwards. look at the videos. if anything my feet are more forward in the second video with no wobbles. it has nothing to do with feet position, but if i moved my feet more rearward, all my wheels would wobble.

kour Posted April 4, 2018 Share Posted April 4, 2018 every so often i wobble, but i don't think it's due to my feet placement. i think it's a combo of how much force is being applied to either side of the wheel, and also whether i'm leaning forward or backward. when i mess around with crouching down while riding about 50% of the time i start wobbling Quote Link to comment Share on other sites More sharing options...
