  • Get a good quality bike with standard components and you should be able to repair it easily.

    As other said avoid cheap low cost bike but also very high end bike that are more likely to use proprietary parts.

    For the frame the best option would be steel, if it does break you can easily weld it back with a regular welder.

    Aluminum is the second best option, a bit lighter but it will fatigue, so over the years the frame will wear out slightly.

    Carbon is the worst for reparability, very fragile and impossible to repair.






  • Imagine you want to build a cabin in a very remote place in Alaska.

    Getting there is quite difficult, you did it a few times in the 60’s but the path is so bad that you had to throw the truck away each time (around $45,000 per trip, for the truck + gas)

    You are still planning to build your cabin but having to buy a new truck for each trip is not great, plus the fact that only one company can make this SLS truck so you can’t get more than once a year.

    Building a cabin in these circumstances is close to impossible.

    Now SpaceX makes a new Starship truck that can go all the way AND be reused. The trip from the hardware store to the build site now only costs you around $100 for the gas plus truck expenses AND you can now do the trip to the hardware store multiple times a day !

    Now building the cabin becomes way more accessible.

    Replace the Alaskan cabin with a scientific base on the moon or Mars and multiply the amounts by 100,000 and you have an approximation of the situation
