His pants leg that came unsecured is what broke that chain guide.

It also occurred to me, JB Weld and a good gluing clamp is often stronger than the objects it's bonding, that would probably hold you until you get a new one.

I'd make Yamaha pay for a new pair of jeans & replacement derailleur.
I'm not even convinced the front derailleur is needed; it only has the single chainring!
Maybe I'll take it off and see if I have problems with the chain dropping. If so, I'll glue it and put it back.

I would absolutely not do a chain guide. I have heard of plenty of problems from those.
My solution to the pants thing has a 100% success rate over many years: Use a wider 2" velcro cinch strap. Like one of these:
![71mN-y6bBpL._AC_SL1500_[1].jpg](https://ebikesforum.com/attachments/71mn-y6bbpl-_ac_sl1500_-1-jpg.17244/ "71mN-y6bBpL._AC_SL1500_[1].jpg")
I always keep the straps (one for each leg) on the bike in a bag or something. They never leave the bike so I can never forget them.
You want them to be a little bigger than you need them to be so you can engage the velcro and have it still be relatively loose on your leg. They don't need to be tight and this lets your pants move with your leg as you cycle. And a 2" wide velcro cinch connection is just never going to come loose, ever. Your leg will come off before the strap does.
I wouldn't call this a mid drive thing. Its more about having your chainring at just the wrong spot to eat your pants, and that varies bike by bike. My orange hub bike was a pants-eater but none of my mids are and I generally only wear the ankle straps when I have my rain pants on.

I took the chain guide off and rode 23 miles yesterday. 11 miles in, it started randomly shutting down. It was about 1/2 gravel and 1/2 paved. During the roughest part of the gravel, it didn't shut down at all, so I strongly doubt it is a connection issue.
On the way home, there was an uphill stint and I decided to energize it again, hoping for some assistance. Lo and behold, it went the whole way home on Standard or Turbo at 25 mph with no further issues, but the intermittent nature of the fault is sure annoying.
The more I think of it, the more I think it is the battery, hence the "free second battery" as part of the offer.
I will still continue following up with the dealer, as the promotion said nothing about the first battery being shot or excluding it from warranty. ;-)
Here's some ride data:

I followed up with the dealer’s owner via email again today, he had the mechanic call me back and tell me how he fixed another Yamaha ebike with the same problem. He bent the metal support clip up to support the battery more firmly.
He said that customer never came back, so he assumed that fixed it for good.
It didn’t fix mine, I once again found out ten miles into a ride and pedaled the beast home mostly unpowered.
I just sent him an email requesting that he get in touch with Yamaha and tell them about my plight and ask what the problem is; I’m sure they know about it by now, as well as the fix; they just don’t want to volunteer the info and have a bunch of people demanding service all at once.

This was on Shifters Christmas Gift Guide on YouTube. I had never seen it before. It screws into any of your bottle bosses, especially the ones on the front fork, then you can attach any of your strap on lights to it, giving you a different position for a headlight, seems cool.
I really like Shifter's channel. Thanks for the recommendation.
Another one I like, I can't remember the name of right now, is hosted by a Filipino-looking guy who's NOT trying to be a racer boy. He used to be obese, and then got into biking and lost a bunch of weight, but he's good at keeping it real. Do you know who I'm talking about?

Actually, I don't. I'll have to keep an eye out for it.

The PDW Light Nug is one of a few different flavors of this idea. I am having a truss fork made for one of my bikes and a couple of M5 bosses are being put on at the upper apex, or whatever its called, specifically for a pair of these. Also a couple more on the forward steerer extension in case I want to go there instead. So I've looked around quite a bit for whats out there on the market. The Light Nug sticks out a little further than some of the variations out there. I'm not certain if thats good or bad. Its also more expensive. The ones I came up with as alternative solutions are
- PDW Light Nug
- Paul Gino
- Origin8 Eyelet Stub
- Restrap US light mount
I found him; his channel is Path Less Pedaled. He's a big proponent of The Party Pace and is open-minded to new (and old!) tech.

Back to the Wabash. I put the bike in the back of the garage and was going to just wait until the spare battery came. No rush, since it has a 5 year warranty, right?
But my biking buddy at work lit a fire under me and reminded me that I signed up for TWO working batteries, not one. So I drove the bike the 55 miles up to the dealer and dropped it off.
He was accepting and the first thing he said was: "OK, and do you have the key?"
No, I didn't. I left it at home along with the battery, which I had removed to the basement for winter storage.
I asked him to get in touch with Yamaha with the symptoms I've given so far, taking my word for the moment:
Looks like I'm making another trip up there in a couple weeks.
I told him once they have fixed it with Yamaha's advice, I will drive back up with my cycling kit, prepared to ride it at least 20 miles before I bring it back home.

- Battery is not showing any error codes
- Bike works fine for ~10 miles, then it throws the "Er71" code and shuts down. Happens repeatedly after ~10 miles, not at all before.

Oh, thanks. I know this guy. For a long time he financed his channel by selling Party Pace biking stickers. He and his girlfriend packed up and moved to Portugal. I think now he bikes at Picnic Pace, lots of siestas. Although, they did do a video on moving their furniture across town to their new apartment. They managed it strictly using an acoustic, cargo bike, that was fun.I found him; his channel is Path Less Pedaled. He's a big proponent of The Party Pace and is open-minded to new (and old!) tech.

Dropped off the battery & key last Saturday, Dec. 7.
Not sure what to expect in terms of resolution and time frame. I hope it's something like: "We talked to Yamaha and they acknowledge it's a controller firmware issue, so they sent us a new controller to install." and not something like: "We couldn't replicate the problem; come pick it up."
I'm expecting it to take many weeks, anyway.
This is a perfect example of why a fellow should have multiple eBikes. (or at least multiple bikes)
