I visited Nunavut in 2019 as a researcher, the town I was in still used these at some places. Being born after their widespread use I had no idea what it was
I'm pro e-bike for reasons other people have mentioned:
-It's a big win for the elderly and out of shape who otherwise would not be getting that exercise and fresh air at all. I have a friend who's Aunt has a heart problem and apperently otherwise wouldn't be unable to bike without an e-bike.
-It brings many new people into the orbit of biking that otherwise wouldn't. The more bikers the more demand for good bike infrastructure, and the fewer cars on the road, and the more attractive biking becomes as a means of transport in a virtuous cycle. This could be huge.
Though I do worry about a few things:
-I think with its battery an e-bike is significantly more of an issue when people do stupid things like throw bikes in rivers/lakes/ponds. Even if this weren't common in places it still needs a good end of life for recycling.
-I do think maybe some people will be so used to an e-bike smoothing out the ride that they will never go to a full bike, but this may be a relatively low number (e.g. many people choose to bike over driving because they want to exercise)
-Many people on e-bikes in my area are a bit of a menace. Because it takes no effort to use, people fly around at max speed (well above the limit posted on our bike paths) and e-bikes are heavy; if someone gets hit it might seriously injure them. I think it may end up giving them a bad reputation if they aren't managed well.
Currently I've been using these to deal with fungus gnats in my indoor plants; they are quite effective, just put one in my watering can, keep the watering can full so it can steep, and water as normal. It kills the larvae in the same way and after about a month I had no more fungus gnat problem (after trying many other things with no success)
I do wonder about the eventual mosquito adaption to this if it is employed on a large scale though.
