EUC Failure Database

[Asphalt]

With EUCs being relatively new technology and manufacturers operating without serious oversight or accountability, it would be useful to have an open dataset on the failure rates of EUCs. Riders could use this data to make more informed purchasing decisions. This would also (hopefully) reverse the trend of manufacturers using early adopters as guinea pigs.

What data would you like to see in a failure report? 

Here's some to get started:

• Model
• Manufacturer
• Dealer
• Manufactured Date
• Batch ID
• Failure Date
• Failure Time
• Failure Description
• Geographic Location
• Ambient temperature
• Elevation
• Weather
• Rider weight
• Rider riding style aggressiveness
• Rider experience
• Wheel mileage
• Wheel battery level at time of failure
• Wheel temperature at time of failure
• Wheel speed at time of failure
• Wheel customizations
• Damage to wheel caused by failure
• Damage to rider caused by failure
• Damage to third-party property or people caused by failure

We could use replies to this forum topic to log data until it grows larger.

Good idea. But for this information to be useful we would also need sales numbers. Otherwise the most sold wheels will automatically be the most commonly failed. Failure rate requires knowledge of sales figures and those are not easily available. 
 

Our best hope is for the dealers to publish this information. I’ve seen Ecodrift and @Jason McNeil release some failure rate figures earlier.

If manufacturers want to supply sales numbers, that's up to them. They might see it in their best interest to justify why there are so many reports for a particular wheel.

There's value in an open dataset (not controlled by manufacturers or dealers) where riders can see what failures have occurred and if trends start to appear. Currently, there's a lot of rumouring and "mis-rememberings" about reliability of particular wheels (often tainted by brand loyalty). An open dataset would enable objective analysis.

Would the failure reports be guaranteed to be fair? ie would wheel owners who've crashed after a cut out just accept that they were going too fast or would they they just enter the accident as a wheel failure? Or worse, would they be tempted to "threaten" manufacturers that they'll enter their "crash" as a wheel failure unless the manufacturer repairs their wheel? Also, at a time when many riders are trying to legalise EUC's in their country, is it wise documenting failures.

Really good topic, more work needs to be done in this area.

Slightly related: the more I read about people having cutouts the more I think these EUCs should have a black box, similar to planes. We should be able to go back and check the speed, acceleration, temp, battery stats etc etc, after a cutout. These black boxes could "phone home" once and a while to create some really useful databases. Of course, getting the companies to share this info is a different story.

There already are “black boxes” for both Android and iOS, they just have to be manually enabled for each ride...

board failure for gotways is 10-20% depending on model, battery failures around 1%, motor failures 0.2%, misc component failure 10-15%. 

Anecdotal failure rates while discussing potentially being a gotway vendor. ROI isn’t there unless volumes are very high.

Meh, i dont need no stinking black box. We can already record most data for every ride, BY CHOICE. I'd rather NOT lose my choice to NOT have all my data recorded, especially if it can be used by a 3rd party. My wheel happily operates as a standalone device. Having it talk to the internet on its own, or even track gps data with imbedded hardware, sounds like an infringement to me. Hell, I still drive cars that don't have much logging ability. I sure as hell don't want it on my wheel, reporting to some Chinese company.

Getting help from companies to publish actual failure rates, would be a lawyers dream and a company's nightmare. Getting this data in an unbiased way, when so much $$ and competition is at stake, would be a VERY tough feat. I would LOVE to know the honest failure rate and lack of QC for almost ALL the things I own. So far, I havent seen anyone chomping at the bit to broadcast the figures.

Well, there's this
