Keep trying different things until you fix a problem like this.

Reroute wires, twist wires, ground wires, turn things on, off and so forth.

Thanks Don,
If there was a solid wall of cars to my left (as is common during weekday rush hour), and the engine stalled, I might have had to stop on the line dividing the HOV traffic from normal traffic, a single line.  That would be near suicidal. There is something fundamentally wrong with the 2020 Energica Egos. Something wears out or changes at about the 130ish  mile mark. The other Ego had its first stall at around 130ish miles. So it's a problem that is not apparent during new bike testing. It takes some miles before it manifests itself. 
I'm a licensed professional engineer and an Aerospace Stress Engineer by specialization for 35 years. I deal with failure analysis or new designs every day. If I could figure this out,  I would tell you. I wish I were an electrical engineer to solve this problem.
I have to return this one and get my money back.

Best regards,
Steve

For what it’s worth (and it’s probably not worth much), I test rode a (2018?) Ego and it stalled at ~50 MPH during a full power acceleration from a stop. I got the same “get service” message and turning it off and back on fixed it until I got back to the dealer.

Ancedotes don’t make data of course, and maybe it’s much more of a problem for whatever for 2020s, but this definitely isn’t a 2020 only problem.

Hopefully, it is only an EGO problem and does not affect my SS9. I have almost 2K miles on my SS9,  and I have had no such problem.

Have you ridden the SS9?  If so, how did you find it to compare to the Ego? 

I am curious if you would consider a different model if other Energica models have no trace of this problem, or does this problem make you want to give up with Energica?

Just to piggy back and add even less relevant data, the old Translogic review of the Lightning LS218 had it freeze up on the test ride.
I would guess it's a software issue but I agree it has to be addressed ASAP.

Any owners of EVA 107's have similar issues? I wonder if it could be related to the higher power motor in the Ego/Eva107. I've got almost 3k miles on my SS9 and I haven't had any stalling...yet and I ride my SS9 quite aggressively.

If it's unique to the Ego, I wonder if it could be some kind of software or reboot issue since I believe the Ego's are the only models that are limited to 150mph vs 125mph for the Eva107 and SS9.

Sorry you've had such a bad experience with the bikes and I can understand being at the end of your patience, especially with the cutouts happening in commute traffic. Even if my SS9 starts exhibiting the same behavior I'll probably still keep it and ride it since I have another bike to fall back on if needed.

Stalling issue aside, I'm very pleased to hear about the excellent customer service Energica has provided to date even if they haven't been able to resolve the issue for you.

Hopefully you'll stay in the electrics camp and let us know what bike you get next (even if it's not an electric).

I've got almost 3k miles on my SS9 and  I haven't had any stalling...yet and I ride my SS9 quite aggressively.

If it only happens above 80 MPH, I cannot really say about mine.
I normally ride like a little old lady (kinda slow). Mine has  only been above 80 MPH a few times. And BTW, like most European bikes, 80 MPH shown on the speedometer is probably less than  75 MPH.

Hi Don,
I've ridden full fairing sports bike for 30 years now. It's really what I like.
I would buy the Lightning 218 if it had all the Energica electronics. But it doesn't have ABS or traction control. And as far as I can tell, they advertise it but they haven't sold any yet.
My crash rate of 2 to three street crashes a year plummeted to 1 every 4 years since I got my first ABS/TC bike a 2012 Ninja ZX 10R. I will always have ABS and TC and any other thing they come up with to keep the rubber side down.

Thanks Boardwalk. Tha's a good data point. I'm supposed to have a call with Chris Paz today, head of Energica's technical staff for the US. I'll mention your stalling incident.

FWIW, I once had a similar issue with the RMS controller on my bike.  It turned out that I had programmed two of the throttle parameters too close together.  Unfortunately I can not recall exactly what they were and I'm not at home where my notes are.

Any new news on this issue?  I am very curious how all this will turn out in the end.

The saga is over.
Energica did their best to try an figure out why the Ego was stalling but after the second bike stalled in the same situation they decided to refund my money. They did this very promptly and without any protestations.

I'm a mechanical engineer, so electric motors are not my forte. But I've educated myself on the permanent magnet AC motor (PMAC) and I think I know basically what is happening. The engine shuts off sometimes when trying to accelerate between 70 and 80 mph which is around 4700 rpm, which is the end of the max constant torque portion of the torque curve (see graph). At just the right time, I twist the throttle, and it stalls. Full up with gear, I weigh 312 lb (think viking not sumo), so I ask for more voltage momentarily than most riders. The bike tries to protect itself from an overvoltage before the field weakening takes effect. How do I know it's an overvoltage? The stalling has only happened when the bike is 80% or more charged. So the stalling only happens when there is enough voltage to allow it to happen. The battery voltage decreases as the battery charge is depleted. Maybe an electrical engineer on the forum with deeper understanding can propose a better explanation.

I believe that Energica is a quality outfit that will eventually figure out why this stalling occurs. They say it only occurs with bike's I've ridden which is why I mention the only thing I can think of that differentiates me from most riders is my weight. The fact that I rode the bikes every day in SoCal freeway HOV lanes at around 70 to 80 mph, fully charged every morning, gave my bike more exposure to the regime where the stalling can happen.

I'm wondering if there's something different about the EsseEsse9 and it's lower power (80kw vs 107kw). I'm a heavy guy too...250lbs without gear. Add in gear and my usual commuting stuff in the side cases and I would say I'm not too far off from you.

Hi @BigPoppa,

do you mean that you don't experience this on your Esseesse9? Have you tried to reproduce this?

Not that I'm that concerned, I'm nowhere near that weight, but it is something to take into account that there is a situation which will cause the motorcycle to stall (heavy load + heavy acceleration).

It would really reflect well upon Energica if they tackled this.
