It's also nice to be able use your knees to aid in steering. Could be the reason you felt mine had a 'squirrelly' feel to it when you rode it is because of the air pressure in the tire. I have it pretty hard for my 193 lbs, not for your 170lbs. That's probably why your Monster felt kinda 'mushy' to me because it was set up for your lower weight.

kour Posted June 23, 2017 Share Posted June 23, 2017 actually - maybe a grassy field would be the ideal place to test for this problem? no? so many dips and irregularities. then, if you wipe out it's not half as bad as concrete/asphalt/oncoming cars/babies in carriages Quote Link to comment Share on other sites More sharing options...
kour Posted June 23, 2017 Share Posted June 23, 2017 also, (forgive me if this has already been addressed) what happens when one of these affected wheels is turned on and lifted off the ground? 1 Quote Link to comment Share on other sites More sharing options...
Hatchet Posted June 23, 2017 Share Posted June 23, 2017 I had the same thought. Lift it and give it a violent shake before it goes into shut down. See if it freaks out? 1 Quote Link to comment Share on other sites More sharing options...

I see that you guys are acquainted personally, so I don't mean to interfere/impose - but I have to say that when it comes to qualifying for 'taking a beating' I'm pretty sure my msuper meets the requirements. also, @TremF , whose monster was damaged shell-wise. his is undergoing expert surgery, but not as a result of his riding mishap which damaged the shell - to my understanding his monster was still riding fine after the accident.. it was a reconnecting of battery wires snafu that disabled it.

Maybe they thought they had the bug figured out and fixed, but it makes me wonder... why not just roll back to a known good version? If they can't reproduce the problem themselves, I hope they aren't just blindly trying to fix it without testing. Unfortunately, I've seen this a vast number of times with computers and copy machines. Techs under contract come in, mess around for a while, declare victory and dart out the door without testing. They can be slippery as eels. A huge percentage of them seem to be allergic to testing and will try to get away with not doing it even when caught again and again. 2 Quote Link to comment Share on other sites More sharing options...

Only remembering that some here said that the fatter new ACM's felt less comfortable on their legs, and that some fatter versions of an EUC made them have to bow their legs more and/or ride with their feet pushed out more toward the edges of the pedals. 1 Quote Link to comment Share on other sites More sharing options...

I'm very hopeful that everything will be righted within a week or so. Keep practicing in preparation. You should feel confident that if Jason sends out the fixed wheels, they will be fixed.

Let's all knock-on-wood I do. I believe Jason is fully invested in getting this business straightened out and in doing the right thing. I actually haven't been practicing for a week because of a minor work injury that I don't want to make any worse, so luckily(well, kinda) my schedule for getting on the MSuper probably won't be affected by this delay, unless it really drags out. What concerns me is that we track down the cause of any and all problems and fix them so that they don't reappear in new iterations. I guess we can just roll back to an old version. But a new version will come along some day, and we don't want to see the same mistakes repeated.

Marcos75 Posted June 23, 2017 Share Posted June 23, 2017 (edited) @Marty Backe I have seen my video thousand times in slow mow. I cannot upload the video for to see it. I am sorry. But in slow speed you see and here the wheels shaking forth and back. Very scary at high speed. I have taken a belt through the wheel and went outside to make a video. If i have the new board i will test it like this again. I have the oscillation even at low speed over curbs. At this was my luck if not i will have injuries at higher speed.

Popular Post em1barns Posted June 23, 2017 Popular Post Share Posted June 23, 2017 FYI, I just purchased an Msuper3 820wh with manufacturing date 20161116. The motherboard had to be changed after unboxing it as it grilled the LEDs (?!). New motherboard received with manufacturing date 20170603. Wheel was feeling like v8, it was like the algorithm was much harder. After 2 miles, I had the same oscillation issue, luckily at 10mph, and managed to run without falling.... My 4th motherboard is ordered again (I had a temp spare used one in between from the vendor). 4 Quote Link to comment Share on other sites More sharing options...

My 4th motherboard is ordered again (I had a temp spare used one in between from the vendor). I think that if you have an 'older' wheel with a new MB and you got the oscillations, you might conclude that all problems are caused by the MB or the firmware that is on the MB. I still think it is the firmware as the MB probably hasn't changed, except for the 12 mosfet change (but these are parallel connected I believe) Edited June 23, 2017 by MichaelHensen Quote Link to comment Share on other sites More sharing options...

I actually rode @Marty Backe's Monster on side walks for about a mile and didn't really like how wide it was. My knees actually hurt when I got off. I kinda felt like I was 'bull legged" when riding it. @Sven Has a newer version of the Monster and the pads at the top appear to be about half as thick as the pads on @Marty Backe's. I think Marty stated that Sven's Monster felt more comfortable when it came to knee pain. Allen Edited June 23, 2017 by abinder3 2 Quote Link to comment Share on other sites More sharing options...

Popular Post Puce Posted June 23, 2017 Popular Post Share Posted June 23, 2017 Before reading this post I bought this friday morning a brand new Gotway Msuper 3 820, motor 1608 I have several hundreds kilometers experience with a inmotion V5F. The gotway was setup by a Belgian dealer, 3 bar 43 psi tire pressure, sport mode, tiltback 33 Km/h 20 mph. My weight is more or less 60 Kg 130 lb. I rode only 3 Km 2 miles before passing a small road repair not higher than one cm half inch high with smooth border. Immediately the wheel started bumping with strong rotation acceleration while not touching the ground. It only took 2 meter to have the motor beeping and shutdown. I was at 20 Km/h 12 mph when my face kissed the road. I came back home on the pavement at walking speed and had the issue a second time while going down from the pavement to the road where the pavement border was almost at road level. At that speed I was able to control the bump oscillation and could feel my heel going up and down while my toe were stable. Since this problem has been discovered two weeks ago and there still no official communication from Gotway I think I'm better asking for a refund.
