@Lia -- Sounds to my damaged ears like the rapid, flutter vibrations of a buzzer. To my eyes it looked like the buzzer noise only occurred while moving -- not just standing still. Interesting puzzle. Good luck with it!

@Lia -- Thrilling it is to watch your process and progress!

Currently a total of five Onewheel riders show on the Leaderboards more than once: HanahsDax with longtime 1st in the XR Daystreak and 1st in the V1 Daystreak; fuser in 2nd in XR Daystreak and 10th in XR mileage; FranKtheTanK in 3rd in the Plus Daystreak and 4th in V1 mileage (as well as above #1 with another board on that same V1 chart); OnewheelJefe longtime 1st in Plus mileage, and also 6th on the same Plus mileage Leaderboard; and hafid is 4th on the V1 Daystreak and 10th in V1 mileage. All Onewheel riders who are strong in performance!

Last year riding my V1 daily for miles in the very wet Northeast Ohio spring weather, despite Badgering months before, moisture got to the BMS and caused it to do strange things, dumping me a couple of times. First, I took out the BMS. Then, tired of charging EGO batteries and the onboard battery both, I took the onboard battery out -- replacing it with a weighted dummy battery box. I had picked up a technically unusable wiring harness that was throwing an error 16, cut off all the little lines except the main power cables and used that to connect to the EGO battery on the fender. Works just fine. No back lights, but I rarely ride where they would be meaningful.

This year, nervous that the wet weather might get to (or might possibly have gotten to already) the BMS in my Plus, I made a similar modification. This time I completely took out the battery, BMS, battery box, and wiring harness -- with no dummy box in its place. I must say the Plus feels light beneath my foot with only the footpad and bumper there. Road noise is slightly increased. Slight adjustments to riding make it feel somewhat like a different board, adding some variation to my many thousands of miles. Works and feels fine, but no back lights. With the weight of the board reduced, the weight of the 7.5ah EGO on the fender seems less noticeable -- at least on the paved rails-to-trails I mostly ride. Now the only batteries I have to charge are the EGOs.

(A footnote on charging the EGO batteries: Household funds paid for an EGO Nexus Power Station with two 7.5ah EGO batteries included. In the case of an electrical outage, like we had in high winds here last week, I contribute my other EGO batteries to the power station for longer run time. In return I can use the 7.5ah's for my Onewheel, and for EGO firewood-cutting chainsaws. And, the EGO Nexus Power Station doubles as a very convenient, four EGO battery, sequential charger. Beneficial all around! The Nexus, nearly silently with NO generator fumes, ran our upright freezer and some lights for close to 24 hours until line service was restored.)

Fresh flowers and Onewheel Plus.

@LidPhones -- I enjoyed being a pair for a while, sorry for your linkage problem. But I also know the release from riding three boards -- I did it last summer briefly maintaining a Plus streak, while trying achieve two places on the same V1 Daystreak, which I then learned cannot be done. So then I sold one, and this winter concentrated on riding one board at a given stretch of time.

@LidPhones -- Took your place as #10 in the Plus Daystreak. Guessing you are now #9.

@HorsePlay -- On the Leaderboard screen in the app, click on the gear-toothed icon in the upper right. Then you choose the board you want to unlink and click the bar at the bottom that says so.
A Onewheel can be ridden without the app: for example, yesterday I had forgotten my phone, rode fourteen miles or so, and reconnected when I got home; for daystreak purposes the app said that I had ridden ten miles -- anything over ten simply shows as ten.

@HorsePlay -- In the app is a place to 'UNLINK' your board. I unlinked my V1 so I could monitor progress on my Plus -- as the app only shows the more prominent board. Unlinking for more than 24 hours breaks a daystreak.
Relinking restores position in mileage rank -- for example, if I relink my V1 I will be #2 on the V1 mileage Leaderboard with 10127 miles logged, and behind mekegul ahead of me as #1 (but then I would not be able to see the ranking on my Plus in my app). If FranKtheTanK relinks his 15,000 mile V1 he will appear at #1 for V1 mileage, mekegul would drop to #2, and in that case I could be #3.

Got to #31 and now sliding backwards again to Plus mileage rank #33 -- even with averaging sixteen miles a day. There must be more boards being relinked lately. Holding steady at #11 on the Plus Daystreak.
EDIT: Still sliding backwards in rank -- #34 with 4470 miles now, three days later.
