  • Bikes are generally pretty maintainable I would say. Some characteristics that I like about bikes that keep from me having to maintain them to much are:

    • Internal gear hub: the gears are internal which means they don’t get dirty as easily, don’t wear the chain as quickly, and the chain doesn’t need to be oiled as frequently either. Lastly, there’s no real maintenance required of it, while still lasting a long time. Downsides are it’s extra weight, and cost (if you’re using it for urban biking, i would say the weight added is negligible)
    • Check out whether rim breaks or disc brakes, or pedal breaks(forgot the name, but it’s when you back pedal to brake) last longer and whether they require more maintenance. I know disc brakes are better performing and don’t really wear out the bike rim in the same way rim brakes do, but I’m uncertain about their longevity. Disc brakes I believe. Are the more expensive option I believe.
    • Dynamo hub for lighting (if you need it) is pretty expensive but also means not having to worry about your lights and their batteries wearing out, or having to reattach and detach them from your bike.
    • Bike frame: I’m not too familiar with materials and their longevity, but I think if you avoid carbon fiber bikes (which are usually higher end) your frame will be very resilient.

    Another important question is what will you be using it for? Urban biking? Mountain biking?




  • All these people saying its 135 are making big assumptions that I think is incorrect. There’s one triangle (the left one) that has the angles 40, 60, 80. The 80 degrees is calculated based on the other angles. What’s very important is the fact that these triangles appear to have a shared 90 degree corner, but that is not the case based on what we just calculated. This means the image is not to scale and we must not make any visual assumptions. So that means we can’t figure out the angles of the right triangle since we only have information of 1 angle (the other can’t be figured out since we can’t assume its actually aligned at the bottom since the graph is now obviously not to scale).

    Someone correct me if I’m wrong.


  • Can you clarify what you mean? this doesn’t make sense to me. There isn’t an “outer” triangle. There’s one triangle (the left one) that has the angles 40, 60, 80. Both triangles are misleadingly drawn as they appear to be aligned at the bottom but they’re not (left triangle’s non-displayed angle is 80, not 90 degrees). So that means we can’t figure out the angles of the right triangle since we only have information of 1 angle (the other can’t be figured out since we can’t assume its actually aligned at the bottom since the graph is now obviously not to scale).


    • Not everyone has the budget to openly spend 20K plus on a new vehicle, which means lower demand
    • Since not everyone will just buy a new car, companies need to make as much money per unit sold which means luxury cars make more sense These points together should make sense. They are marketing to people that have a lot of disposable income. If they have a lot of disposable income, they probably want a luxurious car. People with 200k+ annual salaries want to keep up with the Johnses so a 20k EV car they can easily afford doesn’t look as cool compared to their neighbor’s 80k+ car. So they want a 80k+ car with all the bells and whistles.

    The reason we stop China is not related to supply and demand so much as stopping companies that China has given unfair advantages to. If BYD was making cars without signifcant Chinese subsidies, then yes I would be bothered by these tariffs as well.


  • I mean the tech is still new as well as the point that SSJMarx mentioned. To add to the list of reasons to make expensive version of cars first:

    • New tech is more expensive usually
    • Not everyone has the budget to openly spend 20K plus on a new vehicle, which means lower demand
    • Since not everyone will just buy a new car, companies need to make as much money per unit sold which means luxury cars make more sense
    • additionally lowering demand is the fact that not everyone wants an EV or feels comfortable driving them (due to its different fueling method)

    I do expect that over time manufactures will begin to release cheaper EVs over time that are aimed for average consumers.






  • What would be the alternative? China is no releasing numbers to how much they subsidize BYD, I doubt BYD would want to be that transparent either.

    From my point of view the US could either wait, try to study and figure out the puzzle for how much China subsidizes BYD in order to come up with a good tariff amount, all while China still accomplishes its goals, or they can put tariffs now and make adjustments later. For all we know, 100% tariff may be too low, we don’t know for certain.

    Let me know if there’s a better plan that’s being talked about.


  • Because China is not fairly competing with other countries. They are subsidizing BYD manufacturing and supply chain with the goal of making BYD the largest electric car company in the world. Yes, their vehicles would probably still be cheaper than other manufactures even before subsidies (Lower cost of living in china, ignoring of fair wages, ignoring of environmental concerns all reduce costs), but they are unfairly trying to make the world reliant on their products.

    That being said, i do agree with your sentiments that we should be making it easier to purchase electric cars. Providing additional discounts or high turn in credit for returning your current gas car would be appreciated so that we can actually make progress on reducing global warming.
