Here in the UK, you can literally buy a decent used car for the price of a new ebike. With prices like this, and poor bike infrastructure, they will never be seen as anything other than a curiousity.
Here's the thing though. I arrived at the conclusion that buying both a car and an ebike is cheaper than buying a car alone, provided the bike replaces the car for the bulk of your trips. You save enormous amounts in fuel and maintenance. The amount of electricity you consume is a rounding error on your monthly bill while you need to budget for fuel when driving, and automobile maintenance costs are easily 10x higher than for a bike. And last but not least, you can go for a long time without replacing your car since you put so little mileage on it, and when you do go looking for a replacement, you can lower the bar in looking for a bargain. Since it's something you will only drive sporadically, it doesn't have to be great.
Y'all are NOT thinking about the incredible way cars are a fiery pit that you throw money into. You don't just buy the car and then use it, it costs money to use a car every damn second you are using it, not to mention the stupid things depreciate value like crazy.
A bicycle takes a laughable amount of maintenance, honestly there just isn't that much to go wrong, it isn't even remotely close how much more money, headaches and time it takes to maintain a car vs. an ebike.
I imagine that is super frustrating but remember, if you buy a used bicycle for cheap, someone could steal your bicycle practically every month and it will still be cheaper and less of a headache than owning and using a car.
While that may be true, the original post stated that you could buy a used car for the cost of a new ebike. It didn't mention the additional costs of ownership, hence we can leave them out of the qualifier. It's not unreasonable to say that the purchase of a used car could be similar in price to that of the purchase of a new ebike.
