That might be the easiest ebike retrofit/conversion I've ever seen. I have concerns about the grip in wet conditions but this looks like a great way to get that ebike I've wanted and not put my perfectly good frame to waste.

So ah, can we buy it? What's the price? Not seeing unless ad blockers are hiding something.
How do these things work legally? Wouldn't the bolt on process count as manufacturing or modifying a motorcycle, depending on where you are?
Friction drive e-bike conversions were popular years ago.

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.

All these sites have hype about AI features like AI Chat. however I use the chat, and it wastes about 3-10 seconds just to load, then I ask for the price, and it fails to understand even the page we were on (edit: "I don't understand what product you're referring to, please tell me the product"). Then I literally paste the page's product from the page into the chat, and it finally wastes my time more and sends a whole essay blob about why it can't tell me the price.

Is this what investors sell to the board about how they are using AI for greater efficiency? Just to waste consumers time even more?

You are not the target audience. The "AI" label is intended to attract stupid people.
If I'm carrying around a giant battery I ought to be able to charge my devices from it, but it is silent on that front.

The design doesn't work if you have a mud guard or pannier rack. Also unclear how easily it is detached. Do I have to take it off everytime to prevent casual thievery? How do I take it off to charge inside? Does it have anti-theft bricking?

I'm struggling to understand who the target market is.

Similar things are on amazon today 300-500. Not worth it imho. If you are going to keep it on, convert your bike with middrive or hub motor once.
These suck, just buy an e-bike they are awesome.
Ouch, love to see a great product like this. However, hate to see that bike theft wasn’t discussed at all.

“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”.

some bike vendor told me that the biggest problem with regular to ebike conversion was that regular bike frames were not strong enough to support the additional forces that the electric bike imposed. And it was why the ebikes were much heavier than regular bikes.

Does anyone know if that’s true and if that applies to conversions like this one?

They aint new. I had one that was driven by a honda gx35 4 stroke

there was another company named "bee" something that did these (gas as well 2 stroke)

and many early scooters, conversions, that all followed the friction style

A couple other people here mentioned that theft is an issue. That's yet another reason why folding bikes seemed like the best use case for this. Not as good as a folding bike that's made for being an E bike, but if you've already got a good folding bike and a bit more zip on your commute is what you need, this seems like a interesting product.
i have a folding cycle and a fat bike. my only two devices still analog and keep me reasonably fit. i dont wanna e-bike them. but if i wanna long distance, this could be nice.
Haha, I like all these adapter designs though my favourite was the Copenhagen Wheel[0]. I saw someone ride one near Mission and S Van Ness and loved it. Sleek device. This particular one in the OP is definitely built for safe societies, right? Definitely not for the North American market, haha!

Am I missing something or that thing can be trivially stolen?
Anything for the world to actually avoid the health benefits of riding a bike. What is wrong with a standard human powered bike? I expect a global obesity epidemic in 10 years as people begin buying/building WALL-E-style beds.
It is decoupled from drivetrain. So, without torque sensor, how does it know when the rider wants to speed up vs. slow down?
