  1. @chrisjunlee has a good thread about it:
  2. I swapped my board out yesterday for the v1.5. Interestingly, the antenna on my v1.4 was pointing the same direction. They must have started doing that before v1.5 came off the line. The replacement board did not fix the issue. I have a feeling King Song thinks we are talking about the random pedal dips caused by EMI. Jason has been compiling info and videos from us to provide to King Song about this issue. I remember the pre-production wheels having oscillation issues at higher speeds, which was fixed by firmware. It's a shot in the dark, but I'm wondering if that previous fix is limiting the power supplied to the motor at higher loads/speeds, resulting in what we are seeing here. I feel like this motor should have enough torque to not be overpowered this easily, so I'm very curious if further tuning of the control algorithm would fix this. Still love this wheel though, and I'm having a blast commuting on it.
  3. I have been using these for a few months now, and I really like them, too!
  4. @ZenRyder Thank you! I've thought about something similar. It would be super nice when I get in to work to be able to just lazily roll my wheel onto its stand. One hard thing is that it makes the dimensions of the stand much more dependent on the specific pedal height of a given wheel, so the ramp would have to be adjustable, or I'd have to make different versions for different wheels. More to think about when I have the time, I suppose
  5. Yes, my stand is on Thingiverse: https://www.thingiverse.com/thing:3778280
  6. Oops, I guess I didn't actually fully explain! But your guesses are exactly correct.
  7. Hmm, probably something like 12-16 hours, depending on how dense you want them to be. For cheap PLA, maybe $4 in material. The PLA I used for my stand, around $7 in material.
  8. I am flattered! In my free time, I've been working on improving the assembly process for these side pads, and actually also new ones for the Nikola based on what I've learned from my 16X pad design, too. But, once I've gotten things more dialed in, I am definitely willing to produce these side pads in small quantities. I'll make a new post when the time comes! As for the stands, I'd have to think about it. They can be pretty long prints... Maybe I need to start my own print farm 😛
  9. On the 16X, yes. On some other EUCs, the pedal hanger comes out below the pedal a bit when folded. So this feature remains there from the original design of the stand, which was meant to be fairly universal.
  10. No problem, dimensions in millimeters and inches:
  11. Hmm, I haven't noticed this. I'll have to check it out when I get home later.
  12. What I know is that, for me, it makes it so that, rather than putting more weight on your toes and using your feet, ankle and calves to put force down on the front of the pedals, it lets me put pressure onto the pads instead, which reduces the amount of muscular effort and fatigue. This is especially noticeable when I'm climbing steep hills! I really like side pads.
  13. Yes, I understand that most people haven't experienced anything like this, and I'm glad! It's pretty scary. I don't know why it is only happening to a very small handful of wheels. Could be some components/portions of layout on the board are juuuust enough out of spec or something on only a few boards. Who knows? 🤷‍♂️ I don't think they would yield the same input into the system, nor require quite the same output from the wheel, I agree. However, you do need more power to keep you up in the case of a large bump (caused of course, by the wheel lagging behind the body of the unicycle/one's own body when the wheel snags on the bump, or when a sudden drop causes one's weight to shift forward hard and suddenly), and believe me, when you feel how limp the wheel gets from the ankle flicks, it is not confidence inspiring that the wheel would have enough power to keep you up after a bad bump in the road. All said, I am looking forward to folks' feedback on the new boards. Fingers crossed it resolves this issue for those of us that have it! I would love to be able to ride 25mph+ on my 16X with the confidence I have on my Nikola+.
  14. @Patton250 The thing is, when I'm riding at 25mph, and the wheel doesn't have enough apparent power to keep the pedals from dipping from a large bump in the road (which we have been simulating with ankle flicks), I really don't think I'm taking it outside of its design parameters. This wheel does use a new technique for delivering power to the motor than previous KS wheels (which is why it is so quiet). Additionally, the effect of back-EMF has a stronger effect at higher speeds, reducing the amount of extra deliverable power to the motor. I suspect this is why we only see this issue at 25mph or more. How the PCB is managing the back-EMF may be a contributing factor to this issue as well. I haven't been as vocal as some others have been in their complaints, but I am patiently waiting for an update from King Song on this. I love this wheel. Jason got a new version of the 16X control board in, and has sent some to a handful of people that have experienced this issue, and we are hoping it addresses this very issue.
  15. I've printed it in PLA and that's been good. Other common plastics like PETG or ABS would likely work well, too. I would recommend at least 4 outer perimeters, and 25% infill has been adequate for me, though 33% wouldn't hurt, especially for PETG or ABS, since they aren't as stiff as PLA. The sides are 1.5cm thick, and the base pieces are 2cm thick.
