postbio Posted August 11, 2020 Share Posted August 11, 2020 (edited) I've hit 500 miles on my King Song 16X and I'm a total addict. I tend to stay around 15-20mph, with some bursts into the mid/upper 20s. As I'm cruising fully geared up, what's always on the back of my mind is the cutoff. Since I don't push it to the limits in speed (31mph advertised), stay above 50% battery, and aware of other things like regenerative braking cutoff going downhill close to 100%, and so on, I don't think I'm in danger of the "usual" cut off factors. What I do fear is the eventual decline of the control boards or other parts of the electronic or mechanical parts that may cause a cutoff anyways as I add on the distance and the EUC ages. What are best practices for inspection and maintenance? I'm a total noob with the specific electrical/mechanical engineering and getting my hands dirty -- which I need to learn for inspection/repair to preempt cutoff. However, I have a graduate degree in theoretical physics, so I can understand things at a high level such as voltage, current, power, Hall effect, torque, vertical component of thrust when climbing, etc. Is there a good app out there for electronic diagnostics? I currently have the KingSong and DarknessBot Apple apps that display this. Is this trustworthy information?

mike_bike_kite Posted August 11, 2020 Share Posted August 11, 2020 Personally I just try to keep the battery within 20% to 80% and check the pressure in the tyre each week. I did consider cleaning my wheel a few months back but then that moment passed. 2 Quote Link to comment Share on other sites More sharing options...
Popular Post mrelwood Posted August 11, 2020 Popular Post Share Posted August 11, 2020 (edited) Inmotion wheels have a self diagnostic feature in their own app, but I don’t know what it actually does. Other wheels do not have such a feature, with any app. These steps will keep your wheel as safe as can be reasonably expected: 1) If you notice ANY change in sound, behavior, range or anything at all in the wheel, heck, even smell, INVESTIGATE THOROUGHLY! Don’t ever think that it may just be a part of aging etc. 2) Keep the battery cells well balanced (every few charges, leave on charger for a few hours after the charger LED turns green). 3) Every now and then check the voltage from an app after charging, before you step on. If it is lower than 83V, balance the cells religiously every time you charge. 4) Store the wheel at 40-60% battery if not being used for weeks. 5) Use a good quality puncture prevention product (Slime, Goop, Multiseal etc). 6) Check the tire pressure every few weeks, and replace the tire before it is badly worn. And of course predict every situation and surface you ride to, well in advance. Imagine a rock and a speeding bicyclist on your side of the road behind every corner you can’t see behind.
