They generally:
* Wear tires surprisingly quickly
* Absolutely suck in any form of weather or terrain condition (dirt, rain, etc.)
* Have ~20% less efficiency than any other drive form.
But, they are easy, and they do work.
That being said, having driven electric bikes for a while, here in France they're ridiculously limited in speed and power. 25km/h limit on flat land usually makes sense (except on long straight lines), but when you get climbing even slightly you get down to ~10km/h and have to provide more effort. I guess that's where the 750/1250W 70Nm unrestrained motor comes in handy, and if you live in a place with lots of small hills the choice is either that kind of motor or a car, not the 1000€-total Decathlon/Carrefour electric bike.
To compare: a tour de france runner outputs 400-500W on mountain climbs while keeping up to 20-25km/h. So a 500W motor (plus 100W power output from yourself) should be enough for smaller climbs!

Enviolo stepless bicycle automatic transmission (never manually shift again, accelerate while continuously shifting under load), with a carbon fiber belt drive (maintainance free, silent, never get grease on your pants or hands again), and Bosch Performance Line mid-motor (strong zippy performance from the geniuses who paid a €90 million fine for Dieselgate), plus GPS tracker with "recovery service" (required for insurance).

It's a dream bike, optimized for comfort and city riding, but Koga is not available in the US, though.
Here's an American bike that has similar features (not as nice as the high-end Koga Evia Pro Automatic though), the Harley Davidson Rush/CTY (step through model is easiest to mount/unmount/ride):

The Enviolo Automatic also come in a heavy duty version paired with high performance motors for bakfiets (cargo bikes), for 3-4 children, big dogs, and groceries:

Edit:
Fair, they're ideal for city bikes, stop-and-go traffic, and the flat Dutch landscape where they're produced, where the biggest "mountains" you encounter are the bridges over canals. Their city model has 310%, trekking 380%, and the new utility hub has 400% gear range, which you can use on a normal bike, bakfiets, or speed pedelec.
How nice should one's bike be that you'd rather turn it into a mediocre ebike for the price of buying a good ebike?
A proper e-bike needs to be designed as an e-bike from the beginning.
* you cannot install them on bikes with a rear rack. Here most city bikes have them.
Which makes me wonder about the cleaning after it rained..
It says on the website it will fit hardtails but not full sus, and that it isn't recommended on knobby tyres due to performance which isn't ideal either.
I could be wrong on all of this but those are just the concerns coming to mind as another mountain biker.
I recall a wheel-mounted rotor system from a few years back that did address theft, tire-wear, and weather, but it suffered from far too little torque and very limited battery life.
Simply bolting things down harder is still defeated by a battery powered grinder.
I think it's ok to define "survive" as an addict who needs (<-also loosely defined) a fix.
You don't generally commit serious white collar crime, tax fraud or do crypto grifts to survive. For petty street crime, I don't really see any other motivation.
Phew, good to hear. Here I thought it would be a hard and complex problem, with lots of unknown unknowns, difficult political compromises, a generation-spanning efforts and many potential solutions with uncertain outcomes, partially contradicting each other.
Instead, we just have to make society better. So, what's step 1?
And if you are still worried about theft in the mean time, you could try looking at wage thefts which has a value greater than all other forms of theft combined.
Making the search process easier makes locating stolen stuff becomes more of an office job that’s cheaper to do so the math works out better.

AngryData> No one goes around stealing bikes just because they want to do bad things.
But people go around stealing Flock cameras because they want to do good things.
So once you take them off the streets for a couple of years, or decades for the more hardened ones, it's fine. It has an added benefit of breaking criminal networks so the future adepts have no place to fence the stolen goods.
I also think you have no idea how much it costs per prisoner per year.
I also think you have no idea how much harder it is for someone to get a job, housing, a partner, etc after they have a conviction. Or how much whatever life they had falls apart, which includes partners, friends, family. And guess what happens when you strip away all of someone's social connections? They lose that safety net, and are now dependent upon whatever society as whole provides. And in the US we have people saying "pull yourself up by your bootstraps" non-ironically, not realizing the whole fucking point of that phrase is that recovering from poverty in the US is extremely difficult.
That money is better spent on helping people who are not able to afford basic necessities, because that is why a lot of people commit property crime.
I suggest you actually open up some studies on this subject because you clearly have no idea what you're talking about. Or just open up a chart reflecting the economy over the decades and compare it with property crime rates.
The US has the highest incarceration rate in the world by both headcount and percentage of the population. How's that working for us? We have one of the higher property and violent crime rates among developed nations. Far higher than nations where criminals are imprisoned for rehabilitation, not to punish. Things like giving them a cell that looks like a bedroom, not pen in an animal shelter.
No, it's actually solved by providing social safety net programs and managing the economy to have entry level accessible jobs that pay a living wage. People steal because they run out of other options. The cost of flock contracts would be far better spent on food pantries, job counseling, emergency housing...
There is nearly zero correlation between the number of police and the amount of crime.
Sure you can use all number of locks, security bolts, and stripping the bike down yourself every time you leave it, but it’s sucks. You’d rather public spaces just be safe.
If there's lot of theft and you can't store bike at a secure place - have a cheap bike.
When i was young all bicycles came with mud guard (then called "fenders") front and rear. Now they seem to be anathema.
Every bike I rode w/o fenders put a stripe of mud up my back!
Of course most bikes still come with fenders, but that's also a major limitation for this device: you've got to remove your rear fender. Maybe this device acts somewhat as a fender, but the site says you can't use it in heavy rain, exactly when you need that fender the most.
Here in Germany if you want to get a cheaper bicycle, other than flea markets, usually they make you mount the pedals yourself, doesn't have fenders, lights might also be missing, depending on the offer.
If, however, they are doing that for commuter bikes...
This is the approach if you go offers on regular supermarkets that also sell bicycles.
Personally I am never going to give more than 400 euros tops, for a new bicycle, it is either that or not much beyond 100 euros at a flea market.
Getting the bicycle stolen or worse, revenge damage when they fail to steal it, is not worth more than that.
You often don’t get pedals on new bikes because you have your favorite pedals that work for you and anything that’s included with the bike goes straight to the bin, because it’s useless trash. You don’t get fenders, because you don’t usually use those on any kind of sporty bike. They’re heavy, they don’t usually work that well, they are often hard to use in bikes with suspension with longer travel or and they can rattle or simply break and fall off if you ride hard. You don’t get lights and reflective elements, because they’re heavy plastic crap that breaks and falls off. If you often ride at night, you probably own some kind of night gear, high powered LEDs, reflective stickers or spokes…
And obviously once that is the norm for “bikes” in general, then why not save a few cents on supermarket bikes.
That plus “already has a bike” is a massive market.
There’s also the fact that many people have bike racks that are fine for traditional bikes but not the additional requirements necessary for some (most?) e-bikes such as weight and strength.

Just because it doesn’t work for you and your specific worldview doesn’t mean others wouldn’t see value in it.
I'm not in the market for this, but I am in the market for making my cargo bike electric. Having to slow down at a traffic light and then start from zero absolutely sucks. It goes very slow, it is rough, and you won't have time. I'd use it just for that specific use-case.
I ride an all-original 1970s steel-frame road bike, which seems like a prime candidate for this sort of product. I'm certain no sprocket-based design would fit it. I'd buy one of these if there was any way to lock it up.
So they say there's a button on the thing itself which is not so much more practical. If they insist on wireless controls, the cost of a waterproof battery-powered button to stick on the handlebars sounds worth it.
I was fine, but surprised he so carelessly and thoughtlessly sneaked up on me and tried to pass when I was already going fast downhill off of a bridge over a canal, on my legal eBike with 25 kph maximum assist.
Pedaling makes you pay attention and gives you direct control over the speed, and the assist drops out once you're going >25 kph. The asshole who hit me from behind probably didn't have time to find the throttle with his hand, and was never really in control of his bike or paying much attention up to when he freaked out and hit me.
What to do about fatbikes endangering our safety?

Fatbikes in the Netherlands 2026: What You Actually Need to Know
Although in my experience when your bike/cargo is heavily loaded, a throttle is nice to get running, especially when stopped at a red light going uphill. Borrowed one like this and it was really useful. But i agree with your sentiment i see many people with throttled bikes going really fast and careless.
Unfortunately ASUS brand is not getting better with these actions.
Bicycles without fenders are typically used for specific recreational activities and those sure as heck do not want this clumsy thing attached.. If they want any form of electrical assistance they would want it a lot more sleek and efficient.
Other than that, it reminds me of the Spartamet, a Dutch piece of tech from 1985 which added a small combustion engine to an otherwise regular city bike.
Obviously I'm talking about good electric bikes, with mid-mounted engines that detect pedaling strength. These feel great, unlike electric motors strapped to bikes, which feel like, well, electric motors strapped to bikes.
Find a bicycle without mudguards and ride very slowly, or just ride on clean roads on a sunny days.
“Easy installation” with two screws seems like a benefit to customers except when they come back to their parked bike only to find their expensive mod also had a hidden feature: “easy uninstallation”.
https://www.pitlock.de/en/set-sichert-2-innensechskantschrau...
From a cyclist’s perspective, this is fundamentally a stopgap product for “curious” customers dipping their toes into e-bikes. I don’t say that necessarily to criticize it. There’s a place for a product that someone can put on any old bike and see if they want to buy a more expensive long-term solution. But that doesn’t make it a product I’d recommend.
The tire wear problem is significant enough that there are heat resistant tires specifically for this type of drum application (designed for old-style indoor trainers, not for use on the road), because use on a drum will cause premature wear for normal road tires.
1. someone has a cheap disc brake bike for pleasure rides (mostly in the sun)
2. they get something like this for commuting or whatever
3. now they're on their disc brake bike most days (including when it rains), going faster than they're used to
it's not the end of the world, but it also doesn't seem great
From experience I can say that it seems like a lot more common sense to simply replace the front wheel of your bike with a wheel containing an electric motor, rather than attaching whatever Asus is selling to your bike.
