  1. Today I was riding my V8 on my daily commute like I've been doing it for 2 months. I was around 15mph on asphalt flat terrain, when suddenly the inmotion v8 gave up and I went body against pavement. It didn't play any different warning sound it just suddenly didn't do anything. As I've had a couple events where the wheel slowly titled completely and now gave up totally, is there a data logger where I can retrieve the wheel facts of the issue ?? I really want to know if something failed, overheat, frozen, over-speed. I can't really trust it, this thing might be trying to kill me. Maybe it has a buggy firmware, this device must have a log memory that logs every event and then later be retrieved, just like a tesla car. Facts: As I dragged myself to grab it out of the road I noticed the blue lights were still on. Temperature this morning 30 degrees Fahrenheit. About -2 celsius. Battery was probably around 92%. I do full charge at home and I had only ridden about 1.5 miles. I've set its max speed to be 19mph so the wheel beeps at 16mph and start tilting back. Not sure if it's even possible to go to 19mph as it plays the warning sound and tilts back. Yes, lots of cuts, lacerations and pain. Lucky is winter and I was riding with a big jacket. Not sure if I had any major complication as I'm still waiting for the pain to go away. Please let me know how do you guys troubleshoot falls, if I can retrieve logs it will be very useful.
  2. Shutdowns generally end like this and are as painful as this looks. Notice how her feet are in space and can't push against anything to break the fall. If, like me, you ride slower than you can run, overleans and other mishaps can be recovered by stepping off but the physics is different in a shutdown and you can't just step off. It is like this. This guy demonstrates the technique for an unpowered dismount. From the moment of unbalance he is falling but he lifts his knee quickly enough to get his foot forward under his body and uses the forward momentum to lift him like a pole vaulter. He knows it's coming and the physics is not opposite to what he is expecting so a shutdown for you is more difficult than for him. My four ended in more pain than any other mishap. On many wheels battery protection has been prioritised over rider protection which can lead to a shutdown without warning. Wheels designed this way and fitted with low quality batteries can shut down at any time but even with good batteries they become dangerous as the batteries age. A rider is only likely to be aware of a rare and mysterious catastrophic failure on a wheel that was for a long time safe. Early battery replacement with good cells will avoid shutdowns or the battery can be modified. The graph below for an Airwheel X8 shows published battery data overlaid with testing data of an aging cell X (black), damaged cells X (grey) and a generic battery with different, damaged cells X (blue). The discharge rate for the X tests was 0.2 amps. The aging cells were still able to sustain a voltage above the tilt back/warning voltage long enough to warn a rider but the damaged cells went from above the warning voltage to below the shutdown voltage too quickly. The generic battery had a shutdown voltage higher than the warning voltage, making it unsuitable for this Airwheel X8 from new. A longer version of this summary is published elsewhere.

    KS 16 - B Not Working

    Good evening everyone, long time reader, first post, The following situation occurred suddenly this evening, please read and share your 2 cents. Was out on a evening ride, when i stopped to have a piss, the sun had just gone down... I then returned to my KS that was leaning against a park bench.. i reach for my unicycle, and immediately notice it is not balancing anymore, i try lifting it, nothing... then i remember a similiar case and i predict i will not be able to shut it of, i try, and yes, the euc will not shut off, i wait one minute and try to connect with my phone, it connects but no information is available, its like the app is -empty- i continue to try to shut it off, after a few tries it gives a long beep and shuts off. now of course i am feeling optimistic, so i go ahead and turn it on again, only to observe the following: Some more info: battery level was at 62% at time of incident. Total distance about 1300 km, we have suffered some minor crashes along this way, we've had a broken fuse about 2 months ago, nothing seemed to be out of order before the defect, sound and tingling in the toes felt good. Any ideas what i could try?

    Cutout / Faceplant Metrics

    Thankfully I have never experienced a cutout, and I believe i've pushed this thing pretty hard from a Wattage standpoint, but not so much speed out of fear of a faceplant. Has anyone experienced a cut-out on the MSuper 2? Is there a hard speed limit that it cuts out at? Or is there more a Wattage exceeded after a certain speed combination? For example I know @logos122 has a high speed version and will try to keep wattage under 1000 when riding > 30kmh (correct me if i'm wrong). Could he theoretically go to 50kmh as long as wattage was under a certain number? It would be nice to know the metrics, or combination thereof that keep us from face-planting due to a shutdown without learning first hand. If anyone has experienced a cut-out on the MSuper2, please reply with your model, power, and what what going on when it cut out on you... Thanks!

    Unexpected shut down

    I just want to put it out there that my Airwheel X3 has shut down unexpectedly four times now. I have been badly hurt. You are merrily going down the street and then fall flat on your face. Absolutely nothing you can do about it. I don't trust the unit anymore and want a full refund (the unit was only 4 weeks old when I first experienced this). The company I bought the unit from Airwheel.com are being unhelpful. They didn't respond to my emails for some time and now the burden is on me to get the unit up there for them to have a look. Would be interested to hear other peoples experiences of this.
