It’s not that hard to fold sheet metal into three sides. I’m not sure why these are notable in any way at this point.

Linnaean taxonomy classifies apes and monkeys as two closely related groups. This is the classification system most people are taught in grade school.

Cladistics is a style of classification that seeks to organize species and groups of species from when they branched off of other groups of species. In this style, everything is defined by novel features, but they are still members of the more ancient clade. Birds for instance, would be a novel clade emerging from Dinosaurs, and thus all birds are also dinosaurs, but not all dinosaurs are birds.

Because there are two groups of monkeys with unique characteristics (new world and old world), and apes have unique adaptations not found in either group, we have no way of cladistically defining a monkey in a way that meaningfully does not also include apes.

As a side note, this is where the phrase “there is no such thing as a fish” comes from. ‘Fish’ in the Linnaean sense are a huge and diverse category. Two random members of the fish class would likely be far, far more distantly related than a random mammal and a random reptile.

I got mine about a year ago after a test-drive, I absolutely do not regret it.

Previously I had done a moderate to low amount of biking when I could, but now I commute ~20Km to work and another 20 back most every day in the spring, summer, and fall. I even commute occasionally in the winter when paths have been properly cleared.

I went upper ‘mid-range’ and ended up spending up spending about $3000 CDN on it, (as a daily commuting vehicle, it’s much cheaper than a second car would be.) I researched reputable brands, and I would absolutely not trust a strangely branded discount Li Ion battery from the internet.

You still have to put in a decent amount of work peddling, but the electric motor makes the bike’s speed, acceleration, and range much better than it would be normally.

The infrastructure of your area and what you would be doing with it will play a big part in what sort of ebike is right for you. I prioritized distance, speed, and carrying capacity, but I am going about 40 Km a day on it, so other bikes might be better suited to other purposes.
