    MSuper X wheel wobbles (misalignment?)

    thanks for the tip. The wobbles are more from the acceleration than the braking. I'll try lowering the pis (once the replacement pedal rods arrive). For some reason I figured the X would use a similar psi as the Tesla (tried everything from 30-45 and 45 felt about right).

    MSuper X wheel wobbles (misalignment?)

    I heard a werid squeal yesterday and tried to remove the side panels, when I got to the left pedals, it was stuck. A long painful process later, turns out the left rod is dented. I’m thinking maybe my rods weren’t centered or something about it was causing wheel wobbles. Hopefully when the new rods comes in, it’ll be wobble free

    MSuper X wheel wobbles (misalignment?)

    Thanks, surprisingly I am getting better results by mounting with my weaker left leg instead. Seems like it’s my mechanics at this point

    MSuper X wheel wobbles (misalignment?)

    Hi everyone, On the Tesla, I can quickly and cruise at 25-27 mph without any speed wobbles along the way. On the MSuper X, replicating the behavior leads to automatic wheel wobbles where I have to compensate by re-positioning myself off-centered to lead with my left shoulder (or slow down and retry again) I tried the wheel lift test but can't be certain of the results (appears to wobble) since I', not strong enough to hold the wheel steady till cutoff (could just be my body shaking and not the wheel). My wheel is 49psi and with a bit more than 6oz of slime (I don't get how its possible to measure from that bottle). Thanks everyone for your help! I'll try to setup my phone to record the wheel test later tonight.
  5. hey @verizo43, can you elaborate a bit on this? You use this to detect wheel misalignments? My problem is resolved now but I'm curious to hear/learn more
  6. hey @Glasco Martin IV, I purchased a spare one from eWheels. @Jason McNeil managed to find a spare handle (inside half). I haven't installed it yet but I should since the handle is a bit loose now. Someone did a carbon-fiber wrap on their MTEN3 so I purchased a roll and plan to sand down the scratch area and wrap the entire wheel with it. Just have to find time to do it.
  7. @Marty Backe and @meepmeepmayer, this is the Post fix Tesla tilting without any vibrations
  8. Hey @Marty Backe and @meepmeepmayer, following @Jason McNeil advise to “re-center” the motherboard, this resolved the problem. at first, I had no idea what he meant. However, after removing the 4 screws on the left side panel, I tugged the motherboard closer toward me and made sure it was sitting on the case properly and voila, problem went away. I’ll post a video when I get home (rode the MSX to work instead). note, the Tesla vibration was really strong yesterday when engaging the brakes downhill, strong enough that it threw my balance off a bit. I’m glad everything was resolved and didn’t require taking off the outershell (which I still can’t do, probably bc I don’t have the right tools to safety dislodge the plastic)
  9. Thanks @meepmeepmayer and @Marty Backe. I'll confirm the motherboard is fastened and not shifting on a tilt. I got a response from eWheels and Jason mentioned that the motherboard could also be off-centered. The vibration is getting a bit worse and starts to vibrate as I'm braking. I"ll report back tomorrow. Appreciate the help as always
  10. Hey @Marty Backe, since no one replied. I was wondering what your thoughts are regarding the weird strong vibration noise coming from the left side of the wheel when the wheel is tilted and not moving
  11. Hi everyone. I was teaching my friend how to ride an EUC and the Tesla dropped on the left side a few times during the hour at about 3-4mph. When I rode the wheel later, I noticed a weird vibration when the wheel is tilted left and my dominant right leg has weight on the wheel (basically every red light). Following the advice on another Tesla vibration thread, I retightened the interior pedals screws and the taped anywhere on the outer shell suspected of being the culprit. However, looking at the videos, it seems like the vibration is coming from within the motor and only appears to be on the the left side. Does anyone have an idea what's happening? Thank you!

    MSX customizations-sharewhat you’ve done

    I’m also curious how you added the extra batteries
  13. Thanks for the detailed response @who_the. I'll open the case after work tomorrow and run your recommended diagnostics. Fortunately, I don't think there's any side-to-side free play of the wheel or I would have fell today during the daily 4 mile ride (the app said I reached 24.3 mph). Thanks for the grip tape tip @Hansolo. I'll have to decide between your recommendation and @who_the 3M suggestion. @Marty Backe, I can't believe you were able to jump off the Tesla, land into a run and then hurdle over a 4inch divider. I think the divider would have gotten me if I stuck the landing. @Scooter Man Fran, your MSX looks like how my tesla (minus the rim dent). Sorry to see that your baby is in that shape. I am interested in how you end up repairing the wheel [outside of buying a brand new battery-less MSX =) ].
  14. hey @Marty Backe , wish you had a video of that fall. I'm impressed you were able to land on your feet. I was aiming for that but the second my right leg planted, I knew this was beyond running speed and planting the second leg down would mean a full face+chin with chest plant. The Killer 187 Wrist Guards are pretty good but it left the wrist a bit bruised / swollen. (I ordered the Demon United Flexmeter Double Sided Wrist Guards D3O hoping those won't leave bruises in the future). My hands has no scratches so I'm grateful to retain my skin. I also wore the Fox Racing Titan Pro Elbow Guard which helped since I landed on the elbow into triceps quite hard after the hand (sore elbow and tricep but nothing is broken). What really is shameful is the backpack is stitched with 1000D Cordura "ripstop" fabrics which I now know is pure marketing and doesn't really stop all rips. Amazing the contents of my bag weren't damaged (portable air compressor, battery pack for the phone and the eWheels fast charger) btw, thanks for all your youtube videos (added the slime + always carry an air-compressor). it's extremely helpful and I plan to get a leatherman soon (those are pricey).
  15. Hi, I already mentioned the below to @Jason McNeil but figured maybe someone on the forum has recommendations. My questions are: 1. Are there some specific MSX grip tapes or does any skateboard grip tape do (seems like the latter would suffice)? 2. Has anyone successfully hide/fix carbon fiber scratches (unfortunately it's not the side-panels which seems more easily replaced. There is a YouTube solution using sandpaper, a grill-pattern to mimic carbon fiber, and a bunch of different spray paint colors [black/silver/high gloss something]). 3. Is there anything I need to check with the internals after 10-12 miles crash? The wheel slammed into a curb and I rode approximately 6 miles post accident without hearing anything strange (I'm planning to reopen the wheel and tighten the obvious screws). 4. How do other MSuperX owners mount their lights? I have an upgraded Evolva and resort to using it with my hands since the clamps I tried would fall off. Thanks everyone. Below are post-accident screenshots and the back story for anyone interested. After almost 6 months of daily riding, I was involved with my first EUC accident late last night when a cab driver took the wrong turn at a fork and decided to rectify the solution by making a hard right to cut across 2 lanes of traffic + the adjacent bike lane (which I was riding on) and over the sidewalk / concrete divider to reach the correct fork (go lost NYC cab drivers). The location of the fork was unfortunately after the apex of a hill which limited visibility and I was going about 20mph when the cab started its super-illegal maneuver. I had to decide whether: 1. swerve left out of the bike lane onto the main road into unknown traffic behind me (this would have prevented the crash but if there were cars behind me, I probably would have gotten rear-ended with a trip to the hospital or worst). 2. stay on the bike lane and hope the driver climbs over the divider by the time I get there (seems quite risky since the current trajectory is directly into the cab). 3. swerve right and take that fork (this would have also prevented the crash but that fork was the service road entrance onto the highway and I would have been vulnerable to any traffic behind me that were speeding over the apex. Also the would place me in front of the cab driver after he climbed the divider). 4. slow down as much as possible and eject with the hope I can stop well ahead of the cab's path over the divider. (this was the safest choice in the 2 second window to make a decision) I slowed down as much as I could prior to the 6-inch tall curb (about 10-12 mph) and jumped into a hard plant with my right leg (slow down attempt #1) then I tucked my left shoulder forward and slammed my left hand (intentionally) into the concrete to force my self into a tumble (slow down attempt #2) onto my shoulders and back. As I was sliding against my backpack, I slammed my right hand (slow down attempt #3) and planted my feet to stop sliding. I was hoping not to slide into the path of the cab as it was driving over the divider. Fortunately, the crash made such a loud commotion that the cab stopped climbing over the divider and despite my efforts, I did not stop sliding far enough. In addition, somehow as I slid, I managed to look behind to track the MSuper X (did not want the wheel to crash into me). Luckily when the wheel jumped the curb, it landed on its side into what @Marty Backe calls "the Gotway dance" and spun in a circle until I retrieved it. I did not know what do in this situation. Call the police? Is my EUC going to get me into more trouble? Do I assault the cab driver out of anger because he knew he was wrong and was very apologetic that he "didn't see me" despite all the lights I had on (could be because of the apex of the hill). I decided after catching my breathe for a minute to do nothing except decline the driver's offer to go to the hospital and rode the remaining 6 miles home. As upset I am about the damage to the new wheel and gear, I'm extremely fortunate to walk away from the solution on my own. My only wishes were that if it had to happen, that I was riding my already scratched-up Tesla (the first wheel I learned on) and the accident was captured (trip was 17 mile / 1.5 hour and I must have turned the camera off at a prior intersection). The photos below shows the extent of the damage. (my TSG Pass helmet did not hit the floor, super lucky here). Note, the front trolley handle was already slightly cracked before the accident as I over-tightened the screws following @EUC GUY waterproof tutorial ( @Jason McNeil already sent a replacement part last week). From now on, I'm using the high-intensity upgraded Evolva at night, I rather blind someone ahead of me than risk hearing how they "did not see me"
