Is this like high school peer pressure?
It's 2025 Is an Emtb in your near future?

I could just Google this, but, I figured I would ask here. Do E bikes have any kind of ERG mode? Like a trainer has. It would limit you at whatever watts you want to pedal at. If you go over say, 200 watts, the cranks would just spin with no resistance
This would be good for recovery rides, or any intervals really.
You could take an E bike and make it a training tool which is kind of interesting.

No, and I truly wish they did. I use my e-bike for recovery trail rides and it's been good, but not perfect. This is what it typically looks like in trail mode.
Not too dissimilar to a road recovery ride IME.
The design room session:
Engineer: Oh hey we should put erg mode on this
Product guy: So the user can set it at 650 watts and just go balls out consistently? Then run into a tree at 44 mph and die?
Engineer: Yes, exactly that
Product guy: That's a hard no

what I’m saying, it actually would not assist you at all. It will just cap your power at a certain watt.

I was never a solid "no", but I was planning to wait a few more years as I knew the technology would continue to improve at an exponential rate. However, when a lot of my riding friends started getting them the timeline was accelerated. I figure I'll get a new one in about 4 years. Maybe the tech progress will settle down a bit by then... 🤣
You have PM pedals?
It comes with a built in power meter which broadcasts out. I was pleasantly surprised to find that feature after I bought the bike.
Check DCRainmaker. I just did a quick search but gave up as I don't know the search term that doesn't come up with 500 other things.
I can swear he reviewed a hub a few years ago that basically added resistance like ERG mode. Part of it was a "Use this and you can ride with your wife and also get a workout" thing.

Ok, not as "smart" as you probably would like.
Hands-on: The AIRhub Pro Resistance Wheel
Last year about this time I tried out the original AIRhub while down at the Tour Down Under. That product is essentially a front wheel that provides resistance that you can control from your smartphone via Bluetooth Smart. It has

So you are doing 300w,@90 and it starts to add assist to keep you from going over?
It’ll just spin faster. Like erg mode on a trainer
Yes, I think that means you are putting in more watts, cause you'll be going faster. To counter more watts it adds assist. Hence, @Norm's statement
The trainer removes resistance when you spin faster. To support this, it adds resistance when you spin slower.
It doesn't care about your target cadence, it cares about the wattage

Still a no. Cant see paying what you need to for a decent Ebike, when I could get a somewhat older, but decent moto for the same or less money. To be honest,I paid way less for a good trail horse, and these days I ride him more than anything else. It's as good as a workout as an Ebike, probably the same amount of expended energy, and no stupid battery to charge. I dont hate Ebikes, I think they're great for folks who wouldn't be out riding without them, but I cant justify what they charge for what is basically an electric moped. Never thought much of mopeds when they were a thing in the '70's and '80's. Still dont now.
Maybe I’m not explaining it right. Or maybe it doesn’t make sense.
I'm getting the idea you want a clutch that slips and prevents you from putting out too much power...
Yes. That’s the idea
with electronic controls it's possible but the ebike aspect seems unnecessary except that it provodes the power.l to run the clutch. (Or did you want the motor to provide the extra to maintain a given speed?)
A torque limited system could be mechanical in nature. Or a cadence based system (centrifugal clutch).
